What Are The Factors That Affect The Efficiency Of A Process?
Efficiency What is the efficiency of a process? There are many factors that are taken into account when calculating the efficiency of a process, but
efficiency can simply be summed up as the ratio between the energy input and the energy output of the system. According to the First Law of
Thermodynamics, the efficiency of a system cannot be more than one hundred percent. The First Law states that energy cannot be created or
destroyed, only transformed. As stated before, there are many factors that can affect the efficiency of a system. A few examples of this may be
but are not limited to: excess heat dispersion throughout the system and loss of heat during delivery (i.e. copper pipes). A fusion reactor's
efficiency has the same difficulties as other processes do in terms of having multiple variables that can affect the efficiency of the process. A
fusion reaction can lose efficiency due to loss of heat during the delivery of the hot plasma. This is caused by the use of copper piping and the lack
of insulation that copper piping has. The reason that the heat from the system travels to the surrounding air is due to the Second Law of
Thermodynamics, which states that energy also has a quality and flow rate. Energy has a tendency to flow from a system that has a higher energy
state(fusion reactor) to a system with a lower energy state(air or atmosphere). Another way that the efficiency can be affected during the fusion
process is dependent on the length of the pulse. It has been proven that having a long pulse during the process will increase the efficiency. The use of
spherical tokamak in the design from David Kingham, Alan Sykes, and Mikhail Gryaznevich has proven to increase the efficiency of the fusion
reactor as it allows the system reduce the magnetic field by a factor of ten which in turn also increases the stability of the plasma throughout the
system. In their study, the results they found for their "Super Compact Neutron Source" were on the less impressive side considering the hopes for a
fusion reaction were very high. According to their report, they were able to get approximately anywheres from one to two megawatts of of output for
an input of six megawatts of neutral beam

Hydrogen Bomb Research Paper
Hydrogen bomb was first studied at the second world war together with the researches of nuclear fission.The main element used in it is hydrogen.
Hydrogen was first found in later 16th century but it was not confirmed as a kind of chemical element by Henry Cavendish before 1766. It is a
chemical element with symbol H and atomic number 1. That means it is the first one on the periodic table and each atom just has one proton and one
electron.And with a standard atomic weight of 1.008, hydrogen is the lightest element on the periodic table. In addition ,it is the most abundant
chemical substance in the Universe, constituting roughly 75% of all baryonic mass. On Earth,most of hydrogen exists in molecular forms such as
water or organic compounds Hydrogen belongs to alkali metals and its family has three members,whose names are protium deuterium and tritium.The
difference is that protium just have on neutrons but deuterium has one and tritium has too.

Draw the dipole moment of the chair and boat configuration. Which of those structures will dissolve better in water and why?
Ans. Chair conformer of cyclohexane has negligible dipole moment due to symmetry and equal charge distribution. On the other hand Boat
conformation of cyclohexane has dipole moment due to the shape of the conformer making it polar due to charge distribution and steric effects. BOAT
CONFORMER (Note: – Grey spheres are C atoms and Blue spheres are H atoms)
Hence the boat conformer is able to dissolve in water but stabilizes soon and turns into the chair conformer making it non–polar and separating it from
water.
How many different configurations of Fluoro–cyclohexane exist? Draw structures but do not minimize in Gaussian.
Ans. Dipole moments of Fluoro–Cyclohexane have increased by a factor of 611.6 as compared to cyclohexane.
This explains how the presence of a single fluoride atom instead of a hydrogen impacts the structure and charge distribution of the cyclic hydrocarbon.
In turn adding a Fluoride atom also increases the energy of the cyclic hydrocarbon creating less stable structures in boat, twist and half chair increasing
О”G and decreasing the amount of other conformers in a solution compared to chair.

The Major Differences Between UPLC And HPLC
As previously mentioned the major difference UPLC and HPLC is the pressure and particle size. Pressures of up 1000 bar can be achieved with
UPLC, which is necessary to maintain shorter retention times. In UPLC smaller particles are used. These smaller particles provide a greater surface
area of the stationary phase within the column, making the separation of the substances much more efficient. However, the smaller the particles are, the
more pressure that is required. A summary of the main differences between HPLC and UPLC can be seen in the table below:
AttributeHPLCUPLC
Pressure6000 Psi100,000 Psi
Particle Size5Ојm1.7Ојm
Flow RateMillilitres per minuteMicrolitres per minute
Max ResolutionRelatively lowRelatively high
The lower particle size is the true reason for UPLC increased flow rate and resolution. This can be shown mathematically using Van Deemter's
equation: H = A + B/Вµ + CВµ. H being the plate height and Вµ being the particle size. The A constant remains constant independent of flow rate
(known as the 'Eddy diffusion term'). The B constant is the diffusion coefficient, and C is the "analyte mass transfer" coefficient. As Вµ decreases, the

Gumustas et al [3] reviewed that UPLC was more efficient than HPLC. In comparison to HPLC, UPLC can run higher resolution methods, using
shorter columns, smaller size of particles, with higher flow rates under high pressure. The injection volume of UPLC is almost ten times smaller than
that of HPLC, which results in good peak shapes and low carryover effects related to column diameter. It was also reviewed that the major
disadvantages of UPLC were the high prices of purchasing and maintaining the instrument as well as the shorter column life due to the increased back
pressure. However, the advantages of less solvent consumption, faster chromatography and better resolution properties overcome these

Nuclear Fusion Essay examples
The Industrial Revolution sparked a need for large sources of energy. Human and animal labor could not provide the power necessary to power
industrial machinery, railroads, and ships. The steam engine and later the internal combustion engine provided the bulk of the energy required by the
industrial age. Today most nations are still heavily reliant on energy that comes from combustion. Usually coal, petrolium, and natural gas are used.
Some hydroelectric, wind power, and nuclear fission sources are used, but in the US they accounted for less than 20% of the total energy consumption
in 1997 (1). Many experts are worried that natural resources such as coal and petrolium are being depleted faster than they are being replenished, which

Unlike solids, liquids, and gasses, plasmas have no electrons surrounding the nuclei of its atoms.
Scientists have been trying for many years to build nuclear reactors that would allow a sustained fusion reaction to occur. There are several factors
that influence a fusion reaction. Since very high kinetic energies are needed for nuclei to fuse, the plasma in which fusion occurs is extremely hot.
Temperatures in excess of 100 million degrees celsius are required for the easiest fusion reaction to take place. Plasmas are fluids, and therefore they
have no permanent shape and will quickly disperse if not confined. A 100 million degree plasma will vaporise any container in which it is placed, so
magnetic fields are used to contain the plasma.
Since the electrons are stripped from the atoms in a plasma, all that remains is the positively charged nucleus, which can be acted on by magnetic fields.
In magnetic confinement reactors, so–called magnetic bottles are created with magnetic fields that confine the plasma. In experiments, however,
plasmas can only be contained for a few seconds before their oscilations cause them to come into contact with the walls of the reactor. The biggest
problem in controlling plasmas with magnetic confinement is their chaotic behaivior. With continuing research, longer containment times are being
recorded.
Inertial confinement reactors use a different approach. Small fuel pellets containing isotopes of

Harold Urey Essay
Harold Urey – Contributions Harold C. Urey is known extensively in numerous fields, some of which include chemistry, biology, and astronomy. His
accomplishments number in the hundreds, the most notably of which would certainly be his discovery of deuterium, a heavy hydrogen isotope with
one proton and one neutron in its nucleus. Although the theory of isotopes was already in place by 1913, and numerous other scientists had discovered
various isotopes of carbon, nitrogen, and numerous others, Urey claimed that only discoveries surrounding hydrogen could be more significant (Rice,
2007). Urey had a systematic chart of countless isotopes, including both known and predicted isotopes, and used this in his research. This system
included two isotopes of hydrogen, one with double the atomic mass of a standard hydrogen atom, and the other with three times the mass. Both of
these isotopes were undiscovered, having only been predicted. Urey became interested in the supposed isotopes of hydrogen after finding out about a
letter sent from a pair of physicists to the July 1, 1931 issue of a scientific journal called the Physical Review. This letter discussed evidence... Show

Faced by problems in the creation of a diffusion barrier for the uranium hexafluoride, this operation became impossibly complex and inefficient.
Urey's barrier was not chosen for the diffusion plant built at Oak Ridge, Tennessee, and he soon after left his work on diffusion. Despite his position
as the head of the project, Urey soon has second thoughts and tried in vain to convince President Harry S. Truman not to use the atomic weapons on
Japan. After the war, Urey appealed more to the civilian control of nuclear weapons, proposing an international ban on the utilization and stockpiling of

The Rosetta / Philae Mission
The Rosetta/Philae mission was an international space mission sent to study the small icy worlds that are comets. Specifically, the target of interest for
this mission was the comet 67P/Churyumov–Gerasimenko. The spacecraft was launched in 2004 and arrived at the comet 67P
/Churyumov–Gerasimenko on August 6, 2014. This space mission was unlike any other because this mission marks the first time in spaceflight history
that a spacecraft entered orbit around a comet and deployed a lander to the comet's surface. The lander itself was a great research vessel as it included
an array of instruments ranging from spectrometers, to microscopic imaging instruments, radio tomography systems, gas analyzers, drilling
equipment, and various surface sound monitors. When the Philae lander was being lowered by the Rosetta craft, it suffered from an unfortunate
series of events which culminated in the lander making final touchdown on the opposite side of the crater than where it was supposed to observe.
The Rosetta/Philae mission not only set a number of first in space travel, but also increased humanity's knowledge about comets in many different
ways. The mission set history by being the first spacecraft to use solar cell technology as the spacecraft's main power source, send back images from
the surface of a comet, make the first analyzation of the composition of a comet, and have a probe land on a comet to perform surface operations and
examinations.
Despite the lander not being in the

This heterogeneous catalyst can be applied to a wide variety of activated and non–activated primary and secondary alcohols. As shown in Table 3,
benzyl alcohol and substituted benzyl alcohols are converted to their corresponding aldehydes efficiently. In the case of benzyl alcohol, after 30 min,
only benzaldehyde was obtained in 99% yield. In longer reaction times (1h), the obtained products are 97% p–OCH3 benzaldehyde and 3% p–OCH3
benzoic acid. The results show that the substituent's have no major effect on the oxidation of benzylic alcohols. A good selectivity experimental in the
case of cinnamyl alcohol and only oxidized in alcoholic group and no epoxide yield was obtained. Manganese(II)non–heme was also used for oxidation
of secondary alcohols and their corresponding ketones were obtained in good yields. We used hydrogen peroxide (H2O2) as the oxidant and
[Mn(BPMP)(OTf)2] as the catalyst for the oxidation of alcohols. To a mixture of substrate (1mmol), manganese non–heme catalyst (1mol %), and
solvent (CH3CN = 3mL) was added H2O2 (1.2mmol). The reaction mixture was stirred for 30 min at room temperature. This system has shown high
catalytic activities for the oxidation of non–activated and activated alcohols under mild conditions as shown in Table 4. Secondary alcohols were
easily converted to the corresponding ketones in excellent yields and reaction selectivity was over 99% in all cases. Cyclic alcohols

The Modern Lifestyle Requires Energy
The modern lifestyle requires energy. Industries need energy in their production; homes need energy to provide a comfortable environment. With the
growing awareness of the need of environmental protection, however, there are debates about sources of energy. For the past centuries, fossil fuels
have always been the most prominent source of energy generation, but it is certain that they will run out eventually. They are also criticized for
polluting the environment and causing the global warming. There are many new energy sources like solar, tidal, or nuclear fusion. Among all the
choices, nuclear fusion, although still not practical, has the greatest potential and best outlook. Governments should develop fusion as the future
energy source for three reasons. It is efficient, safe, and nearly inexhaustible. First of all, nuclear fusion is the most efficient energy source. It
produces a huge amount of power from little material. Moreover, its 'waste' product can be used as fusion fuel again. Nuclear fusion produces a large
amount of energy. The fusion process happens when two light atoms, typically hydrogen, helium, lithium and their isotopes, are fused together to form
heavier element under extreme heat and pressure and release a great amount of energy. Nuclear fusion is a million times more efficient than coal.
According to a professor at Cambridge University, the energy produced by nuclear fusion with "100kg of deuterium" and "3 tonnes of lithium" would
require "3 million

Big Bang And The Creation Of Energy And Matter

Explain what occurred during the Big Bang, including the creation of energy and matter:
The universe was created by the Big Bang. Just before the Big Bang, the universe was just unbelievably hot and at a very dense point, it burst to
expand space faster than light which was at 10–34of a second. The universe doubled in size at least 90 times from the dense point. But the speed of the
space spreading became to change to a slower rate still continuing at this time and day. As space, expanded universe cooled itself down and matter

Redshift is the red end of the spectrum which is radiation from distant galaxies, stars, and other objects. Astronomers found that the further we are
from a star the more its light is redshifted. This tells us that galaxies are moving away from us and that the further the galaxy is the faster it moving
away. The further away the galaxy the more its light is redshifted. The Theory of the Big Bang says that this expansion started billions of years ago.
Scientists discovered that there are microwaves coming from every direction in space. The theory of the Big Bang says that this energy was created at
beginning of the universe just after the big bang and has been moving through space ever since then.

Taking a Look at Nuclear Fusion
Nuclear Fusion Assignment
1.Nuclear fusion is the combination of two light nuclei to form a heavier one. However, controlling a nuclear fusion reaction has proven to be difficult.
State three critical requirements which must be meet in order to achieve controlled fusion. Firstly, high thermal energies are needed to achieve
controlled fusion. High temperature enable the particles to overcome the Coulomb barrier, the energy barrier due to electrostatic interaction that two
nuclei need to overcome so they can get close enough to undergo a nuclear reaction. This energy barrier of the electrostatic potential energy is that
temperature must be maintained for a sufficient confinement time and with a sufficient ion density in order to obtain a net yield of energy from a
fusion reaction. A necessary part innuclear fusion is plasma, which is a mixture of atomic nuclei and electrons that are required to initiate a
self–sustaining reaction which requires a temperature of more than 40,000,000 K. Second, difficulty of forcing deuterium and tritium nuclei within a
close proximity needed to be overcome. The reason is because the nucleus contains protons, and in order to overcome electrostatic repulsion by the
protons of both the hydrogen atoms, both of the hydrogen nucleuses need to accelerate at a super high speed and get close enough in order for the
nuclear force to start fusion. The net result of these opposing forces is that the binding energy per nucleon generally increases

Energy Through Fusion

and Nagasaki, the first ever atomic bombs ever created that had the capability to destroy entire cities, within seconds, and leave suffering for
generations after. Then came the hydrogen bomb, which used the initial fission explosion of an atom bomb to create the process of fusion, an even
more deadly and powerful weapon. Why am I so fascinated with a process that is so devastating? Well the answer lies within the sun. During the early
1920's, it was recognized that the sun probably produced its energy from constant fusion reactions in its core (Hydrogen). The core, which happens to

The motivation to overcome this obstacle is the fact that the materials are very easy to obtain. Lithium, the element that cell phone batteries are made
from, is a very highly obtainable substance that is found in a larger percentage in the Earth's crust than lead or Tin, and can be turned into tritium by
simple nuclei reactions; deuterium, which is not very common, can be created in an almost limitless supply using the hydrogen in water (Provide).
The only major problem, is that to mimic the reaction found in the sun, there needs to be intense heat and enormous amounts of pressure (Provide).
Also, like the energy from the sun, the energy from the plant will dissipate and become less and less the further out from the initial reaction it goes,
therefore, to get the most out of the energy, the pressure needs to not only condense but contain as well (Planet). The best way to get a confining
pressure field is to create a magnetic field. To date, there are several reactors that use a magnetic field to contain the reaction, including the Joint
European Torus (JET) and the Mega Amp Spherical Tokamak (MAST) (World). There is currently a project in France called the ITER (International
Thermonuclear Experimental Reactor), which will open in the 2020s and will be the largest tokamak built and will have 500 megawatts of energy

Essay on Hydrogen Fusion is the Future Source of Energy
Hydrogen Fusion, the Future Source of Energy Abstract The world is currently in an energy crisis with no end in sight. Many technologies can help
reduce our dependence on fossil fuels and have the possibility of ending the energy crisis. Hydrogen fusion holds great promise with its no pollution
energy output. If more energy can be created than is used to start the fusion process, the energy crisis might become a thing of the past. Over half of
the energy used now comes from fossil fuels, which is around 2.77*10^14 KJ in 2003. ITER, which is under construction right now in France, will

JET is a Tokamak developed by the UK in the 1970's. JET stands for Joint European Torus. The fuel used in JET is a mixture of deuterium and
tritium. It was first fired up in 1983 after five years of construction and in 1997 it hit its peak output of 16 MW. JET is currently shutdown because
it is being upgraded to increase its power output to 40 MV. The upgrades are occurring to help out in the development of the largest hydrogen fusion
generator, ITER. ITER is the newest fusion generator that is currently under construction in eastern France. It is being funded by the European
Union, Russia, the US, Japan, South Korea, and China. The project is expected to run for at least thirty years, ten for its construction and twenty for
its usage. The project is expected to cost at leas 10 billion euros, with the European Union paying a hefty part of the sum. The Torus at ITER is
designed to create at least 500 MW for about 500 seconds. The problem with hydrogen fusion is that it still is in an experimental phase. Humans are
still trying to develop a method to gain more energy than is put in. Molecules of deuterium and tritium are the main components in hydrogen fusion.
Both deuterium and tritium are stable isotopes of hydrogen. Fusion shows a lot of promise because it when tritium and deuterium fuse, they release
17.6 MW of energy, the only problem is creating a way to do this efficiently. We believe

The Physics Concepts And Principles Behind Nuclear Fusion
This report outlines the physics concepts and principles behind nuclear Fusion, the advantages and disadvantages of fusion and whether nuclear fusion
could be used in New Zealand. Also, this report outlines the comparison between Fusion and Fission.
A fusion is when a reaction in light nuclei combines to form a nucleus with greater mass. Fusion can take place only under extremely high temperature
conditions. Another name for this process is thermonuclear reaction.
The process of nuclear fusion is important to the future of power production in New Zealand. At the moment New Zealand relies on energy sources
such as hydroelectric, wind power and solar. Hydroelectric and wind power are limited by the possible locations which means another source of
power will be needed. These sources provide consistent, clean energy, nuclear power sources may be able to provide energy in much greater
quantities. The New Zealand nuclear free zone, disarmament and arms central act of 1987 presents any nuclear power plants from being constructed or
opening in New Zealand.
It is expected that the first nuclear fusion power generator will be operational by 2030, being presented by a nuclear fission making it possible for New
Zealand to consider a nuclear power programme. If New Zealand were to open nuclear power stations, the most likely approach would be
deuterium–tritium fusion.
The advantages of nuclear fusion are, theres no CO2 emissions as no fossil fuels are burned, there is no

Explain why or why not. Generally, the neutron determines its chemical stability, although in the case of deuterium the isotope remains stable. This is
because there is insignificant mass difference between protons and neutrons.
Concept 2.2
How do differences in electronegativity result in the unequal sharing of electrons in polar molecules? A molecule containing an atom with high
electronegativity will be more polar than a molecule containing an atom with a lower electronegativity. The higher the electronegativity the more
insatiable the atom becomes when it comes to sharing.
For each of the following, is it a Hydrogen bond donor, acceptor, both, or neither? Aldehyde is a hydrogen bond acceptor. Amino is a hydrogen bond
acceptor and donor. Hydroxyl is both a hydrogen bond donor and acceptor.
What are the functional groups on this molecule? What is the R group to which they are attached? Is the R group hydrophilic or hydrophobic?

The Beginning Of The Universe: The Big Bang Theory
The Big Bang theory.
The Big Bang, what is it? What does it tell us? How do we know that The Big Bag is a viable theory?
The BIg Bang theory is currently the best theory (astro)physicists and cosmologists have to describe the beginning of the universe in which we live.
The theory also has implications on how cosmologists think the universe will end. We call it thebig bang as it was originally thought of as a
preposterous theory; That the universe didn 't exist at some stage and then it just decided to 'blow up ' or 'expand ' from 'nothingness '. However, over
the past century many great minds have contributed to the discovery of physical concepts that have made The Big Bang theory a more accepted theory
on how the universe was born.
So what does theory suggest about the beginning of the universe? The Big Bang Theory suggest first of all, that the universe did have a finite
beginning and before that point, there was nothing. This beginning was around 13.7–8 billion years ago and that it came into existence from a
singularity (something that still defies physical laws as we know them). A singularity is a point that is infinitely dense and are infinitely small. The
universe began from something infinitely dense, small and hot. Where this singularity came from? We don 't know, something that cosmologists debate
about constantly. After the Big Bang had occurred from this singularity, space expanded in to itself at incredibly high rates. This initial expansion called

Tritium Research Paper
Tritium
Tritium is a radioactive chemical and is highly hazardous when the tritium chemical is not handled properly. It can be classified as physical, chemical,
biological, and even clinical medicine. Some advantages from tritium can be used in weapons manufacture such as: iron sights, scopes and watches,
objects with luminous compounds. Tritium is a form of Hydrogen, found naturally in air and water. Unlike most hydrogen, tritium has two extra
neutrons in the nucleus.
A few scientists have discovered Tritium in 1939, such as: Lord Ruthfird, Sir John Cockroft, Ernest Lawrence, Luis Alvarez and a few more. Tritium
was discovered through the method of isolation of deuterium oxide to prepare deuterium gas. By flooding the elements with accelerated ions such as
protons and helium ions it becomes possible to produce ... Show more content on Helpwriting.net ...
However, it can be harmful if too much of it is taken in. Because tritium has one electron, it can easily form compounds similar to hydrogen; thus, a
person will likely be exposed two ways. One is similar to hydrogen gas (HT) or by liquid HTO ( tritiated or heavy water). The HTO is the only
form that has great exposure hazards. With HT gas only .005% of the tritium is deposited in the lungs; whereas, with HTO almost 100% is inhaled and
digested. Tritium can also be absorbed through skin or open wounds; contaminated materials can also increase exposure. If one has been exposed
through HTO, it will eventually be evenly circulated through out the body's fluids. The removal of tritium varies differently to people due to their
bodily excretion rates, temperature and fluid intake. Tritium (H–3) emits low energy beta with a 12.3 year half–life. It does not emit gamma rays.
Biological half–life of tritium is about 9.4 days to 10days. Tritium can be shortened by increasing fluid intake, as we can see in the diagram below (Fig

Why Fossil Fuels Are Not Only Bad
Why Fossil Fuels Are Not Only Bad, But Not Good Enough Coal, petroleum, natural gas. Together, they are the producers of approximately eighty
percent of the world's energy, and, according to the US Energy Information Administration, are predicted to remain as such throughout the early to–mid
twenty–first century (EIA 6). Yet there are far more efficient fuels options than these, as the profound xkcd cartoon to the right suggests, and these
options do not involve polluting the atmosphere, exacerbating climate change, or contaminating marine life with black goo. Additionally, fossil fuels
are nonrenewable resources, and by definition cannot be expected to last forever. They are simply not a feasible long–term option. Therefore, rather
than merely limit the use of fossil fuels, world policymakers should put as much effort as possible into developing cleaner, more efficient energy
options like nuclear fusion. When fully commercialized, these more potent fuel sources should make fossil fuels obsolete by their very presence in the
economy.
Part 1: Fossil Fuels Are Not Particularly Good at Efficiency First, fossil fuels are much less energy efficient than their domination in the energy market
suggests. This fact is best illustrated by comparing the energy densities of the various fossil fuels to those of some alternatives. The energy densities of
the different fossil fuels vary by type. Anthracite and bituminous coal, for example, generally release somewhere between 24 and 35

developed over billions of years and water played a huge roll in the development, shape, and structure. Within this exploratory essay you will gain
knowledge on how Michigan, specifically, was shaped and how water affects the state in many ways and will continue to do so every single day until the
earth ceases to exist.
Description of Michigan
Michigan is one of the fifty states within the United States of America and is favored with having the largest shoreline within the U.S. It is
characterized by two peninsulas, the upper peninsula (which is obviously cooler) and the lower peninsula which holds a vast majority of the land and
also a big chunk of us, Michiganders. The name Michigan comes from the Chippewa Indian word Michigama which means great or large lake. Lake
Michigan was called Michigama by the Chippewa Indians. Our unique state is luckily surrounded by four of the five Great Lakes. The Great Lakes in
our region have vastly influenced our state and those around us. Without Lake Michigan, Lake Superior, Lake Huron, and Lake Erie, we would not
have the large fresh water sources we currently are blessed with, many jobs would not exist, recreational activities would be slim to none, and we
simply wouldn't have the gorgeous views all around us. To say the very least, the state of Michigan is

Pros And Cons Of Nuclear Fusion
Development of alternative energy sources is ever growing. One such source, nuclear fusion, is gaining increasing prominence in the energy world. The
principles of nuclear fusion provide the opportunity of incredible energy production. This review covers the concepts, current prospects, and the
challenges and future developments necessary for the realization of nuclear fusion as a power source. Tremendous research and development has already
occurred into the realization of fusion. Two popular mechanisms are studied: Magnetic Confinement Fusion (MCF) and Inertial Confinement Fusion.

compression techniques in ... Show more content on Helpwriting.net ...
These issues combine to place an unfavorable light on the potential of nuclear power. Nuclear fission, however, is not the only source of nuclear power.
Nuclear fusion is another method which offers the potential to combat some of the ailments of nuclear fission in addition to providing long lasting
power. Nuclear fusion offers several benefits to energy industry. Among the benefits of fusion power is that fusion fuel is readily available, power
produced is reliable, has a low environmental impact, does not produce fissile materials, and carries the same terror risk as conventional fossil fuel
plants [6]. To understand why some of these benefits are true, an understanding of the science behind nuclear fusion is necessary.To start, nuclear
reactions involve the protons and neutrons contained in the nucleus of an atom. This is different from how chemical reactions, like the burning of
fossil fuels, involve the electrons of an atom. In nuclear fission reactions, heavier elements are torn apart. The resulting products are more stable than
the reactant, and energy is

The Atom And The Atomic Of The Energy Level Of Its Electrons
This energy will excite the affected atom, raising the energy level of its electrons. If these electrons are excited past the range of the nuclei's binding
attractive force, then the electron will jettison from the atom. These two particles, the ionized atom and electron, are now detectable indicating the
presence of a neutron. This is the material ionization phenomenon (Crane and Baker). The nuclear reaction induction phenomenon occurs when a
larger nucleus is struck by a neutron. There is a probability that the nucleus will absorb the neutron and become unstable. This instability results in the
decay of gamma rays or other particles such as alpha particles and protons. These particles are easily detected and also indicate the presence ... Show
In the conversion of alternating current to direct current, electrons from alternating current will also enter the diode on the left. However, in part to the
oscillating nature of alternating current, the diode output of direct current will be relatively choppy, since electrons can only move towards theelectron
holes in the P–type semiconductor (Kuphaldt).
As a result of the choppy nature of the direct current output, a capacitor is used to smooth the electron fluxes (Copello). A capacitor is an electrical
component that stores charge. In its most basic form, a capacitor is made up of two metal plates with an insulated layer between them ("Capacitors").
As the electrons flow into the capacitor, their concentration and charge builds up on one plate. Additionally, due to the repulsive nature of electrons, the
buildup of electrons on one plate will push the electrons from the other plate, creating a current out of the capacitor ("Capacitors"). This makes one
plate positively charged and the other negatively charged. At this point, the capacitor is storing energy. So, the capacitor smooths the fluctuating direct
current by slowly releasing its charge between input spikes ("Capacitors"). This generates a more consistent flow of direct current to the electric grids.
Another primary component of the Farnsworth Fusor is its two concentric electrical grids. The DC current produced by the diode will be run

Nuclear Fusion: The Future of Energy
Nowadays, energy is pivotal to almost every major challenge and opportunity the world confronts. Be it for jobs, security, climate change, food
production or increasing incomes, access to energy for all is essential. Sustainable energy is needed for strengthening economies, protecting ecosystems

dramatically over the next 50 years as the world's population grows and developing countries become more industrialized. With environmental
requirements for lower CO2 emission sources and the need to invest in a sustainable energy mix, new energy sources must be developed. At the same

A Comparative Essay on the Original Creation of the Earth
Creation is slowly becoming a taboo topic in our current society and the "Big Bang Theory" seems to be the trending theory of the century. What is the
difference though? The Catholic Church, in 1950, proclaimed that the "Big Bang Theory" did not contradict the doctrine of creation; therefore, the
Catholic Church now teaches something called Theistic Evolutionism. (Brom, 2004) Are many churches teaching a false doctrine regarding the "Big
Bang Theory" or is science exempt from biblical doctrine? This essay will explain what the "Big Bang Theory" teaches, what biblical creation teaches
and how the relationship that the two have. First, let us look at the "Big Bang Theory."
The Big Bang Theory Many people believe that the "Big Bang Theory" was first introduced when Darwin introduced his theory of evolution;
however, this view is incorrect. The "Big Bang Theory" is actually less than 100 years old! In 1929, Edwin Hubble discovered that the Universe is
expanding at an accelerated rate and asseverated that the Universe must have been extremely close together at one time. (NASA, 2014) Edwin Hubble
speculated that the universe must have come from an "infinitesimal volume with extremely high density and temperature." (Takashi, 2000) This new
theory, that the Universe was constantly expanding, caused scientist to speculate why and how the Universe was expanding. In the 1960's and 1970's,
scientist declared that they could confirm George Gamow's theory that the "big bang

A Report Analyzing The Viability Of The Nuclear Fusion
Dear Upper Hutt City Council
Today I am writing you a report analysing the viability of the use of Nuclear Fusion as a energy source in your community. I will analyse the
feasibility of this kind of nuclear power in your community by firstly explaining what nuclear fusion is and how it works. I will then use calculations
to estimate how this new energy produced could compare to the amount of energy used by the city currently.
Nuclear Fusion occurs when two small nuclei fuse to form a larger nucleus (this is not to be confused with fission). A large amount of energy is
released, which can be explained simply enough by the binding energy per nucleon. The nucleons in extremely small nuclei have more energy than
those in slightly larger nuclei. Because these nucleons have more energy, they have less binding energy per nucleon (because the same total binding
energy must be split evenly, therefore more energy=less binding energy to go around). Because of this, when the reaction of two smaller nuclei fusing
takes place, the nucleons must have to lose energy. The subsequent energy that they lose is the energy that is released. For all of this to happen, a
fusion reaction requires utterly immense temperature of millions of degrees celcius, just in order to force the nuclei to move fast enough to fuse and
stick.
The Prime example of Nuclear Fusion is the sun. It is obvious that atoms do not rest: the hotter they get, the quicker they move. Temperatures reach
15,000,000В° C in the

The Energy Source Of Energy
In an era where fossil fuels are the dominant source of energy, environmentalists and scientists are looking for alternative energy sources in the fear
that fossil fuels will sooner or later become consumed by our energy needs. In the hunt to find a strong alternative energy source, scientists have
reverted back to an old formula E=MC2. The indicated formula was first thought up by Albert Einstein to describe a part of general relativity in
the paper "Does the Inertia of a Body Depend Upon Its Energy Content?" Furthermore, in his publication Albert Einstein explains that mass and
kinetic energy are proportionally equal. Meaning you can transfer energy into mass and vice versa. In addition if you are able to transfer mass into
energy that mass will be multiplied by the speed of light (C) squared, meaning that a little mass can turn into a lot of energy. Moreover, Einstein's
reasoning for using the speed of light is because atoms when separated travel the speed of light thus carrying a lot of energy. At the time Einstein
was working on trying to find ways to separate and or fuse atoms in order to gain energy and put his formula to use. However, today we have found
two different ways of doing so in what we call nuclear fusion and nuclear fission.
Nuclear fusion has been around since the big bang, as it is the process that powers stars just like ours and is how our universe continues to grow.
Moreover, nuclear fusion occurs when two or more atoms fuse together at very high

Nuclear Fusion a Feasible Source of Power Essay example
Is Nuclear Fusion a Feasible Source of Power?
Abstract:
Nuclear fusion may be an effective solution to the energy problem in today?s world. Fusion is environmentally friendly and has the potential to
generate massive amounts of power. It is evident that the Sun?s power is fueled by nuclear fusion. Recent advancements such as ITER and NIF may
bring us closer to being able to use fusion. We find that nuclear fusion is a long–term solution to a continuing problem.

Scientists aim to gain knowledge and improve the power output, the time duration, and the energy cost.
Nuclear fusion is a process that occurs when two hydrogen isotopes (tritium and deuterium) fuse together. This reaction produces a neutron and also a
large amount of energy. However, a massive amount of heat is necessary for the reaction to initiate because the nuclei (which have very strong opposing
charges) must fuse together. The temperature necessary for this to occur is over one hundred million degrees Kelvin. When the reaction occurs, the
energy is so great that it is very difficult to contain. So far the known methods of containment are magnetic confinement and inertial confinement. The
magnetic confinement uses a very powerful magnetic field, and the inertial confinement uses the inertia of the reaction.
(Figure 1, wikipedia, ?nuclear fusion?) We will investigate published literature that either supports or reflects if fusion is feasible. We believe fusion
would be a feasible source of power if it could produce reasonably more energy that is put in.
Results and Discussion
There are several methods to create nuclear fusion for power. The most successful is the star, which uses gravity and pressure to fuse hydrogen and
create helium.
Unfortunately we cannot harness a sun and harvest it on earth for raw fusion energy.
However, we can create small reactions similar to that of the sun in the lab and turn the radiant energy

Nuclear fusion is a form of nuclear reaction which occurs when two or more atomic nuclei collide at a very high speed and as a result, join to form a
new type of atomic nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted into energy.
Fusion is currently the process that powers active stars. Fusion was first achieved in 1951 with the Greenhouse Item nuclear test. Research ... Show
Gamma radiation is also a possible byproduct from a fusion reactor. However, the amount of gamma rays produced will be noticeably less than the
amount of x–rays produced and anything that is sufficient enough to shield from x–rays will be more than enough to shield from gamma rays. The only
other places radiation can come from are from the top and bottom of the vacuum chamber. Regardless of how much radiation will be coming from the
bottom of the chamber it will not affect us because we won't be looking under the chamber or above the chamber most likely when the reactor is
running.

On top of this both the top of the bottom are being built from aluminum which will stop some radiation. Lastly, a thin sheet of lead, or a some water
/ dirt can be placed on top or under the container in order to help block the radiation a lot more.
Due to the risks that can occur from high radiation levels, a backup plan has been developed in the case of high radiation levels. To start, at the start
of the project a Geiger Counter will be purchased in order to keep track of all the radiation and determine whether the radiation ever reaches unsafe
levels.
Should the radiation level be determined to be harmful, the reactor will be surrounded by material in

The Future Is Bright with Fusion
With the world's supply of fossil fuels declining, alternative sources of power are an important issue in the minds of scientists and world leaders
alike. While everyone scrambles to find the most effective way to harness solar, wind, and water power, they forget about a form of producing
energy that has been researched for 70 years and is only a hair's breadth from being usable(26). Fusion, the same power that fuels the sun, could fuel
the world's homes and cars. A 1000 megawatt coal–fired power plant requires 2.7 million tons of coal per year(21) whereas proposed fusion power
plant designs only require 250 kilos of fuel per year to produce more power(22).That's 1/10800000 of the fuel required to run a coal–fired plant. Even
with all fusion could accomplish, funding for it has been cut dramatically in the past few years because of the inability of scientists to attain sustained
fusion. Fusion is the key to ending our dependence on coal, oil, and natural gas because sustained fusion would produce 4 million times the energy that
current methods produce and the fuel is harmless and readily available.(thesis statement)
Producing electricity in almost any power plant is a very similar process. In each, a fuel heats water into steam, which then flows through pipes to spin
turbines. When the turbines spin they produce usable power. The main difference between the power plants are the form of fuel used and how it is
used. In a coal–fired, wood, or natural gas power plant the fuel

Edward Teller Essay
Home Life: Edward Teller was born to Jewish parents Max and Ilona Teller January 15, 1908 in Budapest, Hungary. The Tellers were an upper
middle class family due to Edward's father being a lawyer. The tellers also had a daughter Emmi who was twenty months older than Edward. Until
Edward was four he showed few signs of being exceptionally intelligent in fact there was concern that he may lack even normal intelligence. At four
however Edward began to speak in full sentences and show great promise. By age six he was laying in bed at night and work multiplication problems.
He soon also showed great promise as a pianist, something he would enjoy throughout his lifetime. By seventeen young Edward had found the young

He also had difficulty in math but not due to a lack of ability but boredom. This ws illustrated by Edward suggesting a better solution to a problem
that the one provided by the instructor. This lead the instructor Dr. Karl Oberle to state, "So, you are a genius" "Well, I don't like geniuses."
Edward began his university education close to home, bowing to his mothers insistence, at the University of Budapest. His father had talked him
into studying engineering instead of math as his main subject. After a dissatisfying period at the university in 1926 Edward enrolled at the Institute
of Technology in Karlsruhe, Germany. In 1928 Edward again switched schools to the University of Munich, where he would study physics. In 1928
Edward had an accident leaving a moving street car which led to part of his foot being amputated. This delay in his education would also lead to
Edward's final switch of schools before receiving his Ph.D. Edward transferred to the University of Leipzig. He received his Ph.D. in Theoretical
Physics in 1930. Getting started: Teller's first position was an assistantship at the University of Gottingen. Edward would leave Gottingen due to the
increasing level of anti–Semitism in Germany. Edward joined a growing exodus of jews leaving for safer countries like England and the United States.
Teller took an assistantship in physics at the University College in London which fulfilled requirements that allowed him to Win a

Water In Your Glass Might Be Older Than The Sun Summary
The article "Water in Your Glass Might Be Older Than the Sun" presented in the New York Times (Times) by Nicholas St. Fleur is based on the
article "The ancient heritage of water ice in the solar system" from Science magazine by Cleeves et al., and while the Times article correctly
summarizes the article in Science, it is written in a manner that uses vague words to appeal to a general audience and the article disregards a majority
of important information. The article from the Times begins by explaining the theory of waters' origin, stating that it is from ice specks that existed in
a cosmic cloud before the Sun's formation. In order to test the theory, the Times article goes on to say that water from the oceans were analyzed,

The Pros And Cons Of Nuclear Fusion
Fusion is the same process our sun and stars in general use to produce energy. Nuclear fusion reactors are theoretical concepts trying to achieve
controlled nuclear fusion reactions here on earth, primarily with the goal of generating electricity. Nuclear fusion promises to be a much more
ecofriendly and safer alternative energy source compared to: fossil fuels, natural gases, and conventional nuclear power.
Nuclear fusion is a reaction that occurs when two nuclei of lighter elements combine together to form one heavier nuclei in turn releasing vast amounts
of energy and neutrons. Different isotopes of hydrogen will be used to carry out these nuclear fusion reactions being that hydrogen is the lightest
element. There are three main types of fusion that are being theorized as viable options are: proton–proton chain, deuterium–deuterium reactions, and
deuterium–tritium reactions. The most valuable of these being deuterium–deuterium reactions because deuterium is naturally found in ocean water and
is readily available. This reaction would require temperatures far greater than that required for deuterium–tritium reactions and with current technology
it is seemingly unachievable. For this reason, deuterium–tritium reactions are most common.
In order for nuclear fusion to take place the nuclei of two hydrogen atoms must fuse together thus forming helium atoms as well as energy and neutrons.
There is an electrostatic force repelling the protons in hydrogen atoms apart from each

Scientific Creation And The Overlap With Creation Research...
Scientific Creation and the Overlap with Mythology
Jordan Weber
University of Northern Iowa
UNIV 1092–01
Dr. John Burnight Scientific Creation and the Overlap with Mythology Since their creation, humans have wanted to understand the reasons for their
existence. Experts in religion, philosophy, and science have all proposed different reasons for and methods of creation. In recent years, especially with
the rise of technology, science has started to become the medium charged with explaining theuniverse and its creation. This increased focus on
scientific reasoning has changed the way humans understand creation. Some religious leaders have attempted to figure out how to interpret new
findings into their scripture. Others have refused to acknowledge scientific facts. Is what they believe still relevant? While their methods of creation are
not, some of the archetypes may be present in scientific theories. Science is constantly changing, and these findings contribute to new ways of religious
thinking.
The Steady State Theory: Science Proves Itself Wrong
Science and myth have been known to have conflicting ideas often. However, also not uncommon for science to disagree with itself. This can be seen
by the two creation theories that were the most widely supported, the Big Bang and the Steady State theories. The Steady State Theory was the Big
Bang's primary competitor. It proposed that the universe "...was steady or unchanging, except for its size and the amount of matter it contains" (Jones,
1992, p.116). This idea of creation was based upon the notion that matter was constantly being created in the universe with "...no beginning or end in
time, and from any point within it the view on the grand scale...is the same" (EncyclopГ¦dia Britannica, 2016, n.p.). This creation was extremely slow,
at a rate of one atom per 1,000 cubic miles of space every century. Matter that is created appears to be relatively the same as matter seen previously. In
other words, it appears in the same forms observed in the universe, such as stars, galaxies, and planets.
Many people are not aware that the Steady State Theory exists. This is because scientific research has surfaced that favors the notion of the Big Bang.
First, the Steady

Rosetta Research Paper
On March 2 2004, the European Space Agency (ESA) launched the Rosetta spacecraft with the Philae lander on a 10 year trajectory towards the comet
Churyumov–Gerasimenko(67P). Comet 67P was not the planned destination for the Rosetta mission however, the mission was planned for comet
Wirtanen(46P). However, due to the failure of the Hot Bird 7 launch, the mission had to be delayed until they determined the cause of the problem.
The mission was set for a new comet, 67P. The Rosetta mission was deployed using an Ariane 5 rocket, built by the ESA and launched on March 2
2004 at 7:17 GMT from Guiana Space Center.

Figure 2 shows one of these pictures, nicknamed "The Fist" because of its fist like appearance. This is an indication of tectonic layering in the comet.
The other photograph was of a crack. Experts currently do not know why a crack would form on the surface. The only theory right now is that there is
tectonic movement that caused the crack to form. The Rosetta mission also measured non visual data. Rosetta found that the magnetic fields of 67P
oscillated at 40–50 millihertz. It was discovered later that the magnetic fields were caused by solar winds, not the comet's core. This means that the
magnetic field varies based on the solar winds at that moment of time. Rosetta took the isotopic signature of water vapor in the coma, the gasses
surrounding the comet. The water was compared to the water found on earth and it was found to have more deuterium than on earth. The deuterium to
hydrogen ration was three times that on earth. Thus, water on earth could not have been brought by comets like 67P, the comet would have to have
similar ration of deuterium to hydrogen ratio. The water vapor being released by 67P is increasing as the comet heads towards the sun. In June of 2014,
there was an ejection of 300 milliliters of water per second. By August, there was 1200 milliliters of water being ejected each second. This increase of
water vapor in the coma is one of the comet's behaviors as

Fission Vs Fusion

the amount of intelligence and power some countries have. Through certain aspects of science, countries can demonstrate any amount of dominance
they have by demonstrating new technologies and theories. Fusion and Fission is one of the great explorations that man has discovered due to the
benefits it brings to human life. The promise of fusion is enormous due to how big of an energy system it gives and it comes together by fuel that is
obtained by seawater and is also mixed with lithium from the earth's crust. Most people get Fission and Fusion confused and they figure that it is the
same thing.... Show more content on Helpwriting.net ...
Most prefer Fission because it can be controlled but if defense is an option fusion would win. Fusion can be three to four more times powerful than
fission. Fusion has a higher energy rate and blast range capacity. Hydrogen bombs that have been tested have been seen to remain better and greater
than the atomic bombs. A hydrogen bomb uses a fission reaction to trigger the isotope Deuterium in the bomb which causes a thermonuclear reaction
which then is lead by a fusion reaction. During the process the fusion reaction implodes in and the explodes out, that is why hydrogen bombs are
shown to have a higher release of energy and a more destructive outcome. Most people like the United states prefer Fusion bombs over fission bombs
due to the capability of their results. The megaton bomb that Korea is testing has a blast range of 1.7 miles, while Castle Bravo (USA) has a impact
about 80 times stronger than the megaton. Most countries have developed fusion bombs and Iran is now conducting research on its nuclear capacity.
Due to the knowledge that the United States has about both fusion and fission, this is why it is so concerning that other countries are testing nuclear
bombs. If they can perfect their formulas, and get the right range right this could put many countries including the United States in danger. Overall,

A finite, straight tube presents the issues of ''spill[ing] right out'' (Seife 64), of the ends of the tube. The solution to this problem was building a torus
(a circular tube, which by its geometry has no end). This new geometry solves one issue while presenting another. In the linear case a magnetic coil
would compress the plasma uniformly through the perpendicular force implemented by magnetic fields on the moving charged particles. Wrapping a
wire around a torus creates areas closer to the center of the loop where the wires are more densely wrapped near the center. This causes a gradient in the
magnetic field that leads to the tendency for protons and electrons to separate. The separation of the particles ruins the tight confinement required for
potential nuclei collisions. However, as magnetic containment development was being further explored, another possible process was being
considered, which offered solutions which magnetic containment failed to

fields to trap plasma) and apply it to construct a fully functional, nuclear fusion power plant which will harness the energy made from nuclear fusion to
create electricity.. This project is funded by USA, China, India, the EU, Russia, Japan and South Korea. The stated countries have funded a total of 6.6
billion pounds to the French government in order for the project to commence.

This will ensure safety in case of any complications with the reactor.
With regards to the advantages of nuclear fusion, the raw fuel or energy itself is readily available. The elements, deuterium and tritium are basically
unlimited. Fusion will not emit toxic gas and other deadly compounds into the atmosphere, unlike burning coal. Fusion will only release helium gas,
which will not have any effects on the atmosphere, as helium is very abundant on the atmosphere, therefore it will not contribute to global warming.
With regards to disadvantages, the overall cost of constructing a facility which will harness the energy of nuclear fusion is extremely high. ITER's
project costs 10 billion Euros. With nuclear fission, the advantages are that, it is inexpensive to create and harness the energy. Fission also does not
create greenhouse gas. The disadvantages are that, wastes are created from fission which can directly harm life and there is a risk of a nuclear
meltdown which will release electromagnetic radiation to its surroundings.
With chemical changes such as fossil fuel burnings, the advantages are that a lot of energy is released during the combustion reaction and extremely
cheap. Disadvantages are that, fossil fuels release carbon dioxide into the atmosphere, which contributes to global warming.
From the stated advantages and disadvantages, nuclear fusion seems to the cleanest source of energy. It does
