Stiffness and strength are the important factors in determining

Graphene exhibits many unique and powerful properties that brought it to the forefront of research and expectations for the future of modern electronics. As well as its incredible mechanical strength and a Young’s modulus about five times that of steel, graphene exhibits unique electronic abilities that stem from the movement of the delocalized π-electrons of the 2pz orbitals constituting the individual graphene molecules [6]. A description of the electronic band structure of graphene involves

Graphene, a sheet of carbon that is a single atom thick, is the strongest material on earth, silicone-based putty (or silly putty) is the one of the softest, and oddest. When the two got together, electricity happened. Approximately two-and-one-half years ago, researchers in Jonathon Coleman’s lab combined broken sheets of graphene with the toy putty and created G-Putty, a super-sensitive material that detects minuscule changes in pressure to the material. When they placed G-Putty on a lab mate’s

Graphene is the cutting edge material in the field of nanotechnology materials. In recent years, the single layer hexagonal shaped carbon has rocked the world of modern physics and material engineering with its unique electronic properties and manufacturing cost. As a result, extensive researches have been conducted over years in order to discover the new potentials of graphene. In this review, the production method of graphene and the general properties are mentioned briefly. In addition, the applications

Measuring micromechanically peeling layer graphene has been experimentally studied for over 40 years, and transport properties of graphene, the growth in [16among many other potential applications. Graphene is experimental study for over 40 years, and the transport properties of the release layer was measured micromechanically graphene grown in a growth in the copper (Cu) largearea graphene substrate, and a variety of chemical modifi version involves the use of graphene (CMG ), so that the new material,]

ABSTRACT Graphene is pure carbon in the form of a very thin, nearly transparent sheet, one at6om thick. It has been hailed as a miracle material because of its low weight, high strength and high electrical and heat conductivity. Since 2004, the graphene market has risen and with the potential for future application could be a multibillion dollar business. Graphene has been planned to replace conductors and also replace catalysts in enzyme immobilisation. Graphene can be manufactured in ways that

Graphene is a hexagonal two-dimensional (2D) monolayer of honeycomb lattice packed carbon structure that was discovered and successfully isolated from bulk graphite just a few years ago [1]. It is continuously receiving attention from the research community due to its outstanding mechanical, thermal and electrical properties [2]. Due to its fascinating properties, graphene is emerging as a potential candidate material for enormous nano-technological applications such as memory devices [3], nano-sensors

The role of graphene in technological development today and in the future In recent years, the field of nanotechnology developed at a spectacular rate. Scientists argued that substances behaved differently in a bigger (macro) level compared to a micro level. One of the major growths of nanotechnology originated from a simple pencil lead; a humble pencil lead that breaks easily with small amount of force. However, when we divide the pencil lead into just one atom thick, suddenly its strength and conductivity

1.3 Graphene structure, physical properties, and fabrication methods 1.3.1 Graphene structure In 2004, two scientists prepared the graphene, a single planar layer of graphite, which has a double carbon atoms bonds. Each carbon atom joins itself with three atoms by strong σ covalent bonds, the strong carbon-carbon bonding granted graphene a rigid structure. With four valence electrons, each carbon atom can contribute one unbounded electron to form π bonds above the plane of the carbon sheet. Graphene
