Nanotechnology And The Field Of Nanotechnology
Nanotechnology is undeniably justified to modify polymers and this can be supported through the two chosen nanotechnologies; Nanosponges and
TiMESH. Nanotechnology has been using polymers and other forms of organic molecules to perform and create a number of different applications in
the medical, commercial and industrial industries. The use of nanotechnology and polymers together has improved materials and technologies. They
are at a much smaller scale, able to manipulate and create, and can be used for a wide range of applications.
Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers (SPI, 2015). The field of nanotechnology
is growing and one of the most popular areas for current research and developing in a number of different disciplines. It covers a broad range of topics,
like polymer–based nanomaterials, nanoparticle drug delivery, self–assembled polymer films, nanofibers, polymer blends and nanocomposites.
Nanotechnology is not new to polymer science as studies before the age of nanotechnology involved nanoscale dimensions. It is particularly focused on
the nanometer length scale (D.R.Paul, 2008).
Polymers are any class of natural or synthetic substances composed of very large molecules called macromolecules that are multiples of simpler
chemical units called monomers (Britannica, 2013). The size of these molecules raises the question of how nanotechnology and polymer science can
go hand in hand. However, these big

ABSTRACT: In the aerospace industry, there is a great need for new materials which exhibit improved mechanical properties. Materials possessing
high strength at a reduced mass and size make lighter aircraft with lower fuel consumption. The development of new materials with tailored properties
is a primary goal of today's materials science and engineering. This paper gives us a brief idea of the various applications and benefits of
nanotechnology in Aerospace Industries.

Visionary ideas include fault tolerant and self–healing materials. It has been shown that nanoparticles dispersed throughout a material can migrate to

cracks, potentially giving rise to self–healing composites (if sufficient migration occurs to seal cracks). For example experiments have been
undertaken with spherical particles of about five nanometers underneath silicon oxide. With the right coating, the nanoparticles automatically migrate
toward cracks in the silicon oxide. Aircraft safety and security is also being increased through the use of new materials in the interior. One example is
the development of bullet proof materials for sensitive parts, e. g. the cockpit door. High strength and lightweight composite laminates (incorporating
carbon nanotubes in a variety of resins) are being investigated for use in ballistic protection and novel damping materials. An important aspect for the
interior of an aircraft is the need for fire retardant materials. The aim is to meet the stringent specifications demanded of materials used in aircraft
interiors more cheaply and effectively than with the costly specialized polymers currently used. It has been shown that the introduction of nanoparticle
additives to 5 % can lead to a huge reduction in fire risk. On the other hand nanoparticles can also act as fire accelerant. The Boeing 787 concept not

The Impact of Nanotechnology in Our Lives
The Impact of Nanotechnology in Our Lives"Nanotechnology is science and engineering at the scale of atoms and molecules. It is the manipulation
and use of materials and devices so tiny that nothing can be built any smaller." It refers to the use of materials with nanoscale dimensions, ranging from
1–100 nanometers. Nanotechnology impacts our lives today in many ways, such as economically, socially, environmentally, ethically, and more.
Nanotechnology is used broadly in many ones' daily life. Many sunscreens containing nanoparticles of titanium oxide or zinc oxide can absorb and
reflect UV light, while being transparent and allowing visible let through. EnviroSystems, Inc. developed a mixture named nano–emulsion of

Nanotechnology's impact on the ICT industry would increase as smaller processing chips are produced. "What we are proposing is a new type of
computing architecture that is only based on nano mechanical elements," said Professor Robert Blick of the University of Wisconsin–Madison. As the
chips get smaller and more powerful, computers will also shrink in size. Some can be as small as bacterium, while having a large storage capacity.
However, engineers are finding that mechanical fans can't cool down the chips fast enough or are too big for the device. The smaller you make your
devices, the more electrons rush through and the hotter your device gets," said Professor Blick. Heat is now the major factor limiting the size of
laptops. Military weapons can be advanced further, with miniaturized weapons, bullets that can be programmed to strike specific targets, and clothes
can be able to store energy to deliver 'superhuman strength', such as jumping over a wallwith ease.
Despite all the incredible possibilities that nanotechnology provides, there are still limitations to it. While nanotechnology seems to be capable of
creating everything, there are physical limits that all technology would stay within. The technology does not have immunities or miraculous powers
that allow it to do absolutely anything possible. The nature will not be changed, and nanotechnology will definitely not

Now a days, Nanotechnology is widely used in many industrial areas such as, computing, pharmaceuticals, cosmetics, textile industries and many more.
The major challenge is not only to make these materials smaller in size in order to store or process more information but also to optimize the synthesis
process. However, the additional key point of the nanotechnology revolution within the next decades is that it will have the capability to use the
advantage of mesoscopic properties of such Nano sized materials. These properties can strongly differ from the respective bulk counterparts due to
quantum confinement or the high surface–to–volume ratio. For example, there will be increase in bandgap of these Nano materials for which it can be

As the range of the implanted ions become comparable to the size of the small structures, important effects are taken in to account in experimental
planning such as , structural changes induced by point defects, strongly enhanced dynamic annealing and sputtering. Even though a huge number of
different nanomaterial systems can be realized with sophisticated synthesis methods, a lot of desired nanostructures will still remain inaccessible due to
chemical and physical reasons. The main reason for that is, most of the synthesis method work close or even at thermodynamic equilibrium which is an
ideal case. For example, superconductivity at higher temperatures is hard to achieve and yet under research. Issues like solubility limits or surface
reconstructions are difficult or even impossible to overcome during synthesis. One alternative option is the subsequent modification of prepared
nanomaterials such as Nano wires using energetic ion beam irradiation, which enables processes far from thermodynamic equilibrium. This can result
into metastable phases of the nanomaterials/nanostructures with unusual or even exotic structural, electrical, optical or magnetic properties.
Furthermore, ion implantation is a very precise and controllable doping method widely used both in research and semiconductor industries. It was
already established in the 70s, however, mainly used for the electrical doping

The Pros And Cons Of Nanotechnology
Nanotechnology is the gateway to near limitless possibilities for the human race. It opens the window to a new realm we previously have never
experienced–– Nanotechnology is a branch of engineering that deals with the manipulation of atoms at the molecular level. The Institute of
Nanotechnology in the U.K. expresses it as "science and technology where dimensions and tolerances in the range of 0.1 nanometer (nm) to 100 nm
play a critical role". Once automated, the nanoparticles will infiltrate every aspect of our lives– from medical, engineering, biomaterials energy
production, to name a few. Practically everything we use today could be replaced by nanomaterial in some way, and it even has the capability to create

Overall, theoretical evidence can suggest that the financial stability of the future economy with nanotechnology will be fine. It could make the use
of money almost obsolete, or it could drive a much further, deeper wedge between the wealthy and the poor. The above examples are used only in
theory, and like all theory, can be disbelieved and disproven. Because we haven't yet created the advanced technology, we can't say for sure what the
outcome will be. Because of this, there are both strong opposers and supporters, and both have very valid points for their decisions. The slim
possibility that nanotechnology would open up a world that we aren't able to fully control, and thus lose control of, is a very real possibility. It is also
worth mentioning that nanotechnology does include the seeds of mass destruction, (7) and that that aspect has not been fully been explored yet. The
dangers associated with manipulation at the molecular level are indeed very real, and the potential for disaster is not exactly statistically low–scale.
But pushing the boundaries of what is reality and what is science fiction has always driven mankind, and much

Another study conducted by researchers at Tel Aviv University
–published in Nature Communications–hones in on the inverse correlation between the
expression of oncosuppressor microRNA and a pre–established oncogene–a cancer development gene. The study says that this explains prolonged
survival of pancreatic cancer, and the findings may very well yield future cultivation of effective drug cocktails for fighting not only multiple cancer
types but also several other mortal diseases.
Lead study author, Ronit Satchi–Fainaro, chairs the Department of Physiology and Pharmacology at TAU, and he collaborated with Dr. Shay Eliyahu
and Hadas Gibori among others on the study. Pancreatic cancer is widely considered by experts to be one of the most aggressive cancers; most
patients last less than a year after diagnosis. "Despite all the treatments afforded by modern medicine, some 75% of all pancreatic cancer patients die
within 12 months of diagnosis, including many who die within just a few months," according to Satchi–Fainaro. "But around seven percent of those
diagnosed will survive more than five years. We sought to examine what distinguishes the survivors from the rest of the patients."
Satchi–Fainaro adds that his team figured they could develop new therapeutic strategies if

Nanotechnology is found in our every day lives, from the tires on your cars to the medicines that can save your life. Every day this concept improves
our lives. It gives us the ability to discover new and helpful things. Research shows that the problems with healthcare will be minimized.
Nanotechnology will help solve medical problems by identifying the problem and locating it so that is can be treated. It will eventually give us the
technology that only exists in the movies. It will give us the ability to go farther in space and discover if there is truly other life out there.
Nanotechnology will eventually help us to do what many only dream of. The one thing that it will give us that will impact us the most is improve
performance of many of the things that we buy and use every day. It will widen our perspective on life. Nanotechnology is defined as "Research and
technology development at the atomic, molecular or macromolecular levels, in the length scale of approximately 1 – 100 nanometer range. Creating
and using structures, devices and systems that have novel properties and functions because of their small and/or intermediate size. It is the ability to

In the process of respiration, the particles are uptaken through the alveolar regions in the lungs and consequently enter the body allowing them to
interact with many vital bodily components up to 100 nanometers in size. The incorporation of nanotechnology in drug administration (parenteral
routes) is also an area of serious concern. The process of endocytosis via the endocytotic pathway is naturally exploited by many viral pathogens and
this phenomenon has spawned the ground–breaking medical technology known as nanoparticle–mediated drug delivery systems. Although these
systems are currently used to observe areas affected by neurodegenerative disorders such as Parkinson's and Alzheimer's, systemic circulation through
the parenteral routes has the potential to be exceedingly harmful leading to such effects as vascular homeostasis, degradation of immune and
inflammatory systems, and increased pro–inflammatory activity. Once Nanoparticles have entered the bloodstream their organ accessibility is virtually
limitless; succinctly, entry via the blood stream grants nanoparticles the capacity to interact with nearly every single bodily component resulting in a
wide array of anonymous and potentially adverse health complications.

Also, these nanobots can allow "metabolic support in impaired circulation," meaning nanobots can provide artificial blood cells to improve low
oxygen levels (Merkle). Ray Kurzweil in "Nanotechnology: Reinventing Our Cells," says that in the future nanobots will be able to "design genetic
therapies to improve our cells, and will ultimately be able to replace damaged organs such as the liver and pancreas" (Kurzweil 556). These types of
medical advances could very well change the world for the better, especially for people and families who are directly affected by diseases as deadly as
cancer and illnesses as exasperating and deadly as diabetes.
Also, these medical advancements will greatly affect the career world. For example, any person who hopes and plans to have a future in the
medical world, might someday be out of a job. If diseases are stopped instantly by nanobots, then what jobs will be left for doctors? I do not want to
be a doctor, however, I am on a track to become a physical therapist and at the rate these nanobots are going, they may eventually evolve to be able to
fix any minor ailment in the body, including anything in the muscle and bones. If this happens to be true, I might have to change my major or perhaps,
become a nanotherapist!
While nanobots seem to be very beneficial to human survival, they can also be quite terrifying. Ray Kurzweil tells us that by the year 2030,

due to the difficulty in power consumption. The ability to shrink size of transistors will soon be in its limit and so there will be a need of something
which can overcome this problem. Recent growth in the field of Nanotechnology encourage to use it on Computer electronics. The objective of
creating smaller and faster computers can be achieved by using it. It can help in creating devices used in creating smaller and faster computers. The

Some of the practical applications of nanotechnology today are to fabricate smaller faster computer chips for more efficient computers, mobile phones,
or navigation systems. Nanotechnology also brought about the quantum dot laser, which enables faster communication. Nanotechnology could be
utilized by today's society in countless ways and will revolutionize our lives. The advances in medicine would be mind–boggling. Tiny robots could
detect diseases when they've just barely begun to form, repair injuries more completely than ever before, and even body parts with new ones.
Microscopic cameras and other recording devices would change the intelligence and security industry by enabling them to watch and monitor like never
before. We would have the luxury of carrying around huge amounts of information; thousands of music albums and movies–on tiny devices that fit in
our pocket. Nanotechnology will totally change our lives. We'll expect much more from the products we buy–expect, for example, a wrench we buy at
the hardware store will be 100 times as strong as steel. Our concept of size will change drastically; the devices we use today will seem large and
clunky. With nanotechnology, we'll expect the devices we use every day to be tiny, light, and very efficient. If scientists are able to actually make
molecular sized machines, we would no longer have resource problems of any kind. Oil, food, wood, and any other raw materials could be broken down

The Pros And Cons Of Nannotechnology
Introduction to what nanotechnology is:
One would at first believe that it is pure imagination, when told what nanotechnology is, it is going to completely change the way that we act, think,
and as a whole, change the way that our society works and interacts within itself. In other words, dictionary.com has defined nanotechnology as "A
technology executed on the scale of less than 100 nanometers, thegoal of which is to control individual atoms and molecules, especially tocreate
computer chips and other microscopic devices.", this means, that nanotech operates on a scale 1,0 Г— 10–9 meters to 1,0 Г— 10–7 meters. To give a
mental representation of this, if a marble were a nanometer, then one meter would be the size of the Earth(http://www.nano.gov/nanotech–101/what

Nanotechnology gathers all the scientific fields of engineering, physics, chemistry, biology, and material science and places them together and makes
everything run at the quantum level, or nano–scale level, a billionth of a meter, as the name nanotechnology might suggest. Albert Franks, an early
promoter of the applications of nanotechnology defines this technology:
"It is the area of science and technology where dimensions and tolerances in the range of 0.1 nm to 100 nm play a critical role... It encompasses
precision engineering as well as electronics; electromechanical systems as well as mainstream biomedical applications in areas as diverse as gene
therapy, drug delivery and novel dug discovery techniques."
The nano–scale is not just another step toward miniaturization, but a qualitatively new scale. Quantum mechanics, material confinement in small
structures, large interfacial volume fraction, and other unique properties, and processes dominate the new behavior that nanotechnology will require.
Many current theories of matter at the micro scale have critical lengths of nanometer dimensions but with nanotechnology on the rise, subjects such as
quantum physics, which rely on probabilities of certain atoms being in a certain location, will be deciphered.
As knowledge in nano–science increases worldwide, there will likely be

One of the most advanced applications of QD's is its use in drug and gene delivery, methods like polymer and liposome based drug deliveries.
Polymer based delivery is the use of a natural polymer that is known to be or have antiviral or antitumor characteristics, these are referred to a PEG.
PEG is known for there high–water solubility and biocompatibility, these PEG's are attached to drugs to increase their solubility, increase drug uptake
by cells and decrease their renal clearance of the drug. The PEG's ability to do this prolongs the half life of a drug and reduces dosing frequency.
Liposome based drug delivery, is the formation of vesicles where an amount of fluid is trapped inside a Nano–phospholipid molecule. Vesicles can

A Speech On Nanotechnology
Nanotechnology is a term of two words: the first word is "Nano" and derives from the Greek word "Nanos" and it means "Dwarf" or something very
small. The second word is "Technology" and it means applied application of knowledge in a certain field. So nanotechnology is the technology of very
small substances, and it specializes in treating the substance on the Nano measure to produce new, useful, and unique resultants in its properties
[22–23].The Nano is a unique measuring unit and from the physical and mathematical point of view, the Nano equals one part of a billion of the
measured unit. The nanometer (nm) equals a part of a billion part of a meter. Thus, it is 10–9 of a meter. The Nano is used as a measuring unit for very
minute particles [24–26].

By changing the properties of the liquid phase (e.g. concentration, temperature, pH) adsorbed species can be released from the surface and
transferred back into the liquid phase. This reverse process is referred to as desorption. Since adsorption is a surface process, the surface area is a key
quality parameter of adsorbents.
Engineering adsorbents are typically highly porous material with surface area in the range between 102 and 103 m2 /g. Their porosity allows
realizing such large surfaces as internal surfaces constituted by the pore walls. In contrast, the external surface is typically below 1 m2 /g and
therefore of minor relevance. As an example, the external surface of powdered activated carbon with a particle density of 0.6 g/cm3 and a particle
radius of 0.02 mm is only 0.25 m2 /g.
However, adsorption is one of the promising methods to remove the dye pollutants from aqueous system completely. It was, therefore, thought
worthwhile to develop highly efficient and effective adsorbents for the removal of dye from the textile
