LOS ANGELES, CA (PRWEB) May 10, 2013 California Lithium Battery is proud to announce its...

Tweaking graphene chemical sensors may open up many applications Researchers have discovered a technique for controlling the sensitivity of graphene chemical sensors. The sensors, made of an insulating base coated with a graphene sheet--a single-atom-thick layer of carbon--are already so sensitive that they can detect an individual molecule of gas. But manipulating the chemical properties of the insulating layer, without altering the graphene layer, may yet improve their ability to...

The latest research from a Kansas State University chemical engineer may help improve humidity and pressure sensors, particularly those used in outer space. Vikas Berry, William H. Honstead professor of chemical engineering, and his research team are using graphene quantum dots to improve sensing devices in a twofold project. The first part involves producing the graphene quantum dots, which are ultrasmall pieces of graphene. Graphene is a single-atom thick sheet of carbon atoms and has...

Alan McStravick for redOrbit.com - Your Universe Online In 2004, the pure carbon material known as graphene was isolated by two University of Manchester Nobel Laureates, Andre Geim and Professor Kostya Novoselov, quickly leading to the discovery of a whole new family of one-atom-thick materials. Now researchers from the University of Manchester and National University of Singapore have shown that by building multi-layered heterostructures of graphene in a three-dimensional stack,...

Writing in Nature Communications, the researchers report the first graphene-based transistor with bistable characteristics, which means that the device can spontaneously switch between two electronic states. Such devices are in great demand as emitters of electromagnetic waves in the high-frequency range between radar and infra-red, relevant for applications such as security systems and medical imaging. Bistability is a common phenomenon – a seesaw-like system has two equivalent states...

Metallurgical test work from Graphite Creek material is ongoing to develop a simple...

NOVATO, Calif., April 29, 2013 /PRNewswire/ -- Graphene Technologies, a company pursuing commercial applications of the carbon nano-material known as graphene, has been issued US Patent Number 8,420,042 for a breakthrough process for atom-by-atom synthesis of graphene by the exothermic chemical reduction of carbon dioxide. This process represents a dramatic departure from the current methods of producing graphene, such as chemical vapor deposition and chemical exfoliation of graphite....

FARMINGTON, Conn., April 25, 2013 /PRNewswire-iReach/ -- Most TV watchers are familiar with the commercial jingle that's ingrained the notion of cotton as the 'the fabric of our lives'. In the industrial world where advanced materials reign, graphene is the new cotton. Graphene's unusual properties derive from its structure, a single-atom-thick sheet of carbon atoms, with the atoms arranged in honeycomb lattices.
