This paper discusses about the survey on the various magazines, conference papers and journals for understanding the
properties of enamelled copper wires mixed with nano fillers, fundamental methods for synthesis and characterization of carbon
nanotubes. From all these papers, it was noted that the research work carried out in an enamelled copper wires filled with nano fillers
has shown better results. It was also recorded that the research work was carried mostly with single metal catalysts and very little
amount of research work has been carried out on the synthesis of carbon nanotubes using bimetallic catalysts.
Organometal halide perovskite solar cells: Degradation and stabilityTaame Abraha Berhe
Organometal halide perovskite solar cells have evolved in an exponential manner in the two key areas of
efficiency and stability. The power conversion efficiency (PCE) reached 20.1% late last year. The key disquiet
was stability, which has been limiting practical application, but now the state of the art is promising, being
measured in thousands of hours. These improvements have been achieved through the application of
different materials, interfaces and device architecture optimizations, especially after the investigation of hole
conductor free mesoporous devices incorporating carbon electrodes, which promise stable, low cost
and easy device fabrication methods. However, this work is still far from complete.
Sensors are needed convert real life quantities into
signal variations and hence has a very high importance. Or-ganics semiconductors have their own advantages, which can
be exploited to create sensors. One of the mostly used sensor
based on organic materials is the Organic Field-Effect Transistor
(OFET). The channel material made from the organic compound
interacts with the analyte and in turn causes variations in the
device parameters.
The major applications of OFET sensors are as bio-sensors,
chemical, and gas sensors. Bio-sensors helps in disease diagnostics
by detecting DNA, proteins, enzymes etc. Chemical sensors are
used to find out the presence of ions, humidity, and pH levels. To
get more information, furthur discussion is about a single OFET
sensor fabricated with P3HT and CuTPP used for detecting nitro-based explosive compounds. OFET sensors are very promising
and could be used in real applications in near future.

Atomic and Crystal Structure
23. A conductor is a material having a low resistance which allows electric
current to flow in it. All metals are conductors and some examples include
copper, aluminium, brass, platinum, silver, gold and carbon. Very little
energy is required to promote electrons into the low-lying empty states.
Generally, the energy provided by an electric field is sufficient to excite
large numbers of electrons into these conducting states.
An insulator is a material having a high resistance which does not allow
electric current to flow in it. Some examples of insulators include plastic,
rubber, glass, porcelain, air, paper, cork, mica, ceramics and certain oils.
The key difference in insulators, conductors and semiconductors lies in the
difference in bandgap energy. Metals have no or an overlap bandgap
whereas insulators has a wider bandgap that doesn’t promote the easy flow
of electrons into the conduction band.
Semiconductors on the other hand have their electrical properties mid-way
between insulators and conductors. They have a narrow bandgap such that
electrons could be excited from the valence band into the conduction band.
Increasing the temperature of either a semiconductor or an insulator results in
an increase in the thermal energy that is available for electron excitation.
Thus, more electrons are promoted into the conduction band, which gives
rise to an enhanced conductivity. Examples of semiconductors are Silicon,
Germanium, Indium Thin Oxide
24. Newer Branches of Materials ScienceNewer Branches of Materials Science
• Nanotechnology: a relatively new area grown out
of techniques used to manufacture semiconductor
circuits and controlled drug delivery systems
• Machines can be produced on a microscopic level
– Example - miniature robots to do surgery inside the
body or miniature chemical laboratories and
instruments that will continuously analyze blood and
dispense medications inside the body.
– Nanodrug formulations for disease detection and
treatment
25. Materials TestingMaterials Testing
• Materials testing is a much narrower field
than materials science or engineering
• It is a way to determine the strength of
certain materials
• It is mostly used to determine safety. Ex.
concrete samples are tested
• It is not used to design new materials to
be used in new applications
26.
27. History of MaterialsHistory of Materials
• Man has been studying materials since
before leaving the cave.
• Due to lack of communication, early man
spent hundreds of millennia experimenting
with stone tools.
• The first metal tools appeared perhaps
only six thousand years ago.
28. History of MaterialsHistory of Materials
• The discovery of “Iceman” in the Alps (btn France
and Austria) in 1991 gave significant information on
early Copper age. He was carrying a copper axe.
• It is dated at about 5300 years, when the first
pyramids were built.
• As our knowledge of materials grows, so does the
sophistication of our tools.
• The more sophisticated our tools, the more
sophisticated our accomplishments

Atomic Description
• Atoms have a (Boltzmann)
distribution of kinetic energies
• The distribution is skewed –
there is a long tail of high-
energy atoms Energy E
No.ofparticles
Peak = kT/2
Mean= 3kT/2
• The fraction of atoms with a kinetic energy greater
than a particular value E0 is:
)/exp(2)( 0
0
0 kTE
kT
E
Ef −
=
π
• If E0 is the binding energy, then f is the fraction of atoms able to
move about in the lattice and promote flow of the material
• So flow is very temperature-sensitive
31. Bonding Between AtomsBonding Between Atoms
• Forces between atoms are
like little springs:
• Determines macroscopic
properties
– Melting Temperature
– Thermal Expansion
Coefficient
– Elastic (Young’s) Modulus
• The coefficient of elasticity of a
solid; the rate of change of stress
with strain
• N.B. These are fundamental
properties which are not
altered by processing
32.
33. Interatomic Bonding and Melting PointInteratomic Bonding and Melting Point
• Types of bonds:
• Ionic bonding:
– Forms between a metal
and non-metal
– Horizontal extremes of
the periodic table
– Egs are NaCl, CsCl,
MgO, CaF2
