The present generation with faster and smaller electronics is the result of advancements in the research. Nowadays research on graphene is a hot topic owing to its unique and excellent properties. Graphene can be produced from mechanical exfoliation, chemical vapor deposition, plasma enhanced chemical vapor deposition, electrochemical synthesis and molecular beam epitaxy so on methods. Electrolysis of graphene is generally carried out to get graphene with high purity. In electronics, graphene is used to make electrodes for touch screens, transparent memory chips, integrated circuits with graphene transistors. The main energy-related areas which depend on graphene are solar cells, supercapacitors, lithium batteries and catalysis for fuel cells.
Graphene was the first 2D material to be isolated. Graphene and other two-dimensional materials have a long list of unique properties that have made it a hot topic for intense scientific research and the development of technological applications. These also have huge potential in their own right or in combination with Graphene. The extraordinary physical properties of Graphene and other 2D materials have the potential to both enhance existing technologies and also create a range of new applications. Pure Graphene has an exceptionally wide range of mechanical, thermal and electrical properties. Graphene can also greatly improve the thermal conductivity of a material improving heat dissipation. In applications which require very high electrical conductivity, Graphene can either be used by itself or as an additive to other materials. Even in very low concentrations, Graphene can greatly enhance the ability of electrical charge to flow in a material. Graphene’s ability to store electrical energy at very high densities is exceptional. This attribute, added to its ability to rapidly charge and discharge, makes it suitable for energy storage applications.
Material characterization is the process of measuring and determining physical, chemical, mechanical and microstructural properties of materials.
Materials Characterization and Applications are below mentioned•
The relationships which exist between the performance of electrical, optical, and magnetic devices and the microstructural characteristics of the materials from which they are constructed. The class uses a device-motivated approach which emphasizes emerging technologies. Device applications of physical phenomena are considered, including electrical conductivity and doping, transistors, photodetectors and photovoltaics, luminescence, light emitting diodes, lasers, optical phenomena, photonics, ferromagnetism, and magnetoresistance.
Carbon materials such as graphite and coke are usual components of friction materials. Graphite can be either natural or synthetic, but all types converge to the flake morphology, at least at the microscopic level. The lubricant properties of graphite are intensified by metal sulfides, especially antimony trisulfide. Small particles increase the positive benefits of graphite rather than large particles. The synergy between graphite and metal sulfide can be due to a direct interaction between the two materials by means of bonds involving dangling bonds or oxygen atoms of graphite edges, which may prevent oxidation and anchor graphite basal plane to the contact disk surface.
A substance which has a molecular structure built up chiefly or completely from a large number of similar units bonded together, e.g. Many synthetic organic materials used as plastics and resins.
Materials science is important for the development of technology and has been or thousands of years. Different materials have different strengths and weaknesses and are uses for different purposes. Materials Science and Engineering is the study of all materials, from those we see and use every day such as a glass or a piece of sport equipment to those used in aerospace and medicine, through that understanding how materials work, can create new materials for new applications as well as develop existing materials to improve performance. They can control the structure of a material, from an atomic level up.
Nanoparticles are particles that exist on a nanometre scale (i.e., below 100 nm in at least one dimension). They can possess physical properties such as uniformity, conductance or special optical properties that make them desirable in materials science and biology. And Molecular nanotechnology (MNT) is a technology based on the ability to build structures to complex, atomic specifications by means of mechanosynthesis. This is distinct from nanoscale materials.
Nanochemistry is the combination of chemistry and nanoscience. Nanochemistry is associated with synthesis of building blocks which are dependent on size, surface, shape and defect properties.
