International Conference on Graphene and Semiconductors July 17-18, 2017 London ,UK

Graphene an important Nano sized material, become an exciting two-dimensional material with distinct attributes in the fields of physics, chemistry, biology and medicine, as well as their related interdisciplinarities. Chemical and biological sensor based on graphene field effect transistor, a single layered of graphene prepared by mechanical cleavage of natural graphite. A systematic nomenclature for this set of graphene-Family Nanomaterial’s, specific materials relevant for bimolecular and cellular interaction. The bio-active molecule/graphene conjugates and the opportunities for the design of multi-functional tools for synthetic biology.

Chemical functionalization of graphene enables the material to be processed by solvent assisted techniques, such as layer by layer assembly, spin coating and filtration. Hexagonal boron nitride is electrical insulating, combined with graphene and other 2D materials to make heterostructure devices. The two dimensional graphene sheet structures for field emission of electrons due to the carrier mobility and electron mass. The filed emitter by using multi layered graphene nanostructure, the graphitic structure of pristine graphene and carbon nanotube is the driving force of their interaction .The combination of graphene with carbon nanotubes to produced hybrids increased electrical conductivity, mechanical properties and high surface area.

Epitaxial growth of graphene obtained on a 6H oriented SiC by vacuum heating at and limited the size of Sic substrates. Micro chemical exfoliation of highly oriented pyrolytic graphite which cannot be scaled to wafer-size dimensions. X-ray diffraction of high temperature annealed Ni film. Diffraction spectra were collected on the annealed Ni substrates over which graphene films are typically synthesized. Graphene that is simply composed of the dissolution of glucose and  in water, vaporization of water and calcination.

Graphene-enchaned lithium ion batteries could be used in higher energy usage applications now in smartphones, laptops and tablet PCs. Graphene has a great potential to use for low cost, flexible and highly efficient photovolatics devices due to its excellent electron-transport properties and carrier mobility. Single or few layered graphene with less agglomeration, exhibit a higher effective surface area and better supercapictor. In hydrogen storage, hydrogen plays an important role in energy carriers. As a fuel of choice it is light weight, contains high energy density and emits no-harmful chemical by-products, hydrogen considered as a green energy.

Graphene oxide has excellent characteristics as a nanomaterial for drug delivery. It expands for anticancer drugs to another non-cancer treatment diseases treatment. Using the fluorescence super-quenching ability of graphene to develop novel fluorescence resonance energy transfer biosensors. Cancer therapy made on exploration of graphene in drug delivery by in vitro test. For clinical cancer and other disease treatment, vivo behaviour of graphene loaded with drugs.

Wide band gap to higher-energy electronic band gaps, difference in energy levels that creates the semiconductor action. Organic semiconductors are pi-bonded molecules made up of carbon and hydrogen atoms. They exist in amorphous thin films. Quantum dots are Nano scale particle of semiconducting material that can be embedded in cells. Larger quantum dots emits longer wavelength in emission colour and short quantum dots emits shorter wavelength in colour.

By alloying multiple compounds, some semiconductor materials are tunable that results in ternary, quaternary compositions. Applications of semiconductors materials are optoelectronic, solar cells, Nano photonics, and quantum optics. Fabrication of cellulose Nano-structures via Nano Synthesis is a direct conversion of TMSC layers into cellulose via a Nano-sized focused electron beam as used in scanning electron microscopes.

Organic photovoltaic cells are solar cells that utilize for organic polymers and small molecules as the active layer for absorption of light and charge transport. Organic semiconductors of their applications are optoelectronic devices, light emitting diodes and photovoltaics. A perovskite solar cell is a type of solar cell which includes a pervoskite structure compound, hybrid organic-inorganic lead material as a light-harvesting layer. Applications of pervoskite are capacitor, sensor, acoustic transducers, optical memory display etc.,

Graphenated CarbonNanotubes are new hybrid that combines graphitic foliates grown with sidewalls of bamboo style CNTs. It has high surface are with 3D framework of CNTs coupled with high edge density of graphene. Chemical modification of carbon nanotubes are covalent and non-covalent modifications due to their hydrophobic nature and improve adhesion to a bulk polymer through chemical attachment. Applications of the carbon nanotubes are composite fibre, cranks, baseball bats, Microscope probes, tissue engineering, energy storage, super capacitor etc. Nanotubes are categorized as single-walled and multi-walled nanotubes with related structures.
