The latest and possibly greenest of graphene production methods has emerged from work conducted at Toyohashi University in Japan. Research conducted by a team lead by Yuji Tanizawa has shown that microorganisms can be usefully employed to reduce grahene oxide flakes by means of respiration and electron transport. The new method vastly improves the current hydrazine vapour and high temperature techniques which are toxic and uneconomical.
For those that haven’t been paying attention, graphene is a wonder material
A report, published in Nature, suggests graphene could be the most sought after material for designer electron devices. Electrons become massless Dirac fermions in graphene as a result of its electronic structure; they travel at the speed of light and are the result of Dirac points that form within the honeycomb lattice of carbon atoms. Graphene is one member of a class of Dirac materials that includes iron-based high-temperature semiconductors, and is show in research conducted by Gomes et al to be a fully tunable condensed-matter system.
Hot on the heels of the NanoBattery comes another contender for the crown of most astonishing graphene device this week. The latest thing to emerge from Hong Kong Polytechnic University, and challenger for the crown, is a graphene based battery that works on ambient heat. The device, which is still to be peer reviewed, works by capturing the thermal energy of ions in solution and converting them into electrical energy. As such it has the potential to provide a virtually never ending supply of electricity from heat sources such as the body, the sun and chemical and mechanical processes.
Roll Up Roll Up, in the world of graphene shares there can be no more apt an answer to the problem of investment choice than to invest in two companies and form a merger, or Roll-up. But, before you close all your trades to invest in this new company , I should just say that the roll up news of the week is not one of take over and consolidation but something all together more interesting; the furling of graphene into carbon nanotubes.
