Graphene is a single-atomic carbon sheet with a hexagonal honeycomb network. Graphene’s electrons take a unique electronic state, referred to as Dirac-cone, where they like they have no mass. This enables them to move rapidly, and gives graphene a high electrical conductivity. The flow of electrons without mass and resistance in graphene is significant as it demonstrates potential for a futuristic high-speed nanoelectronic device.
Graphene combines transparency, electrical conductivity, and high durability into a one-atom-thick sheet of carbon. Even though graphene is known to be a "wonder material," it has still not been successful in industrial and commercial processes and products.
Electrons which act like slow-pouring honey have been observed for the first time in graphene, prompting a new approach to fundamental physics.
Graphene is going to change the world — or so we’ve been told.
A collaborative research proposed that graphene sheets are capable of effectively shielding chemical interactions. This occurrence holds promise for applications such as the quality improvement of 2D materials by "de-charging" charged defect centers located on the surface of carbon materials. The ability to control the selectivity and activity of the supported metallic catalysts on the carbon substrate is another key feature.
An international team of physicists, guided by the University of Arkansas (U of A), has produced an artificial material having a structure similar to that of graphene. Graphene is one of the lightest, strongest, and most conductive materials known.
Graphene is a two-dimensional form of carbon, and successful demonstrations have been carried out by researchers to prove the possibility of interfacing graphene with nerve cells, or neurons, without affecting their integrity.
For years, scientists have been trying to use silicon to produce a lithium-ion battery anode capable of storing 10 times more energy than the existing commercial anodes, and making smaller and lighter batteries with superior performance. Previously there had been two major issues; silicon particles swell in size, and crack and break during the charging stage; and when they react with the electrolyte, they form a coating that decreases their performance.
Zenyatta Ventures Ltd. (“Zenyatta” or “Company”) is pleased to announce significant progress related to the laboratory scale production of graphene from high-purity Albany graphite concentrate by a team of scientists at Lakehead University in Thunder Bay, Ontario, Canada.
Teams at HZB and TU Darmstadt have produced a cost-effective catalyst material for fuel cells using a new preparation process which they analysed in detail. It consists of iron-nitrogen complexes embedded in tiny islands of graphene only a few nanometres in diameter. It is only the FeN4 centres that provide the excellent catalytic efficiency – approaching that of platinum. The results are interesting for solar fuels research as well and have been published in the Journal of the American Chemical Society.
