Graphene ‘onion rings’ – creating graphene nanoribbons atom by atom

By Damir Beciri
20 July 2013

onion-carbon-nanoribbons-1Experiments at Rice University meant to reveal how graphene grows under high pressure and in a hydrogen-rich environment resulted up with development of concentric hexagons of graphene. The process represents the first time anyone has synthesized graphene nanoribbons atom by atom on metal. Once perfected, the approach could lead to breakthroughs in electronics lithium ion… »

Outperforming platinum with a metal-free fuel cell catalyst

By Damir Beciri
9 June 2013

korean-research-groupCollaboration between researchers in South Korea, Case Western Reserve University and University of North Texas resulted with a discovery of an inexpensive and easily produced catalyst that performs better than platinum in oxygen-reduction reactions. The finding is a step toward eliminating what industry regards as the largest obstacle to large-scale commercialization of fuel cell technology…. »

Next generation memory chips from silicon oxide and graphene

By Damir Beciri
17 October 2012

rice-silicon-oxide-memory-1A group of researchers from Rice University led by chemist James Tour came to a discovery that it was possible to make bits of computer memory from silicon oxide and carbon. Their research could lead to transparent, non-volatile, heat- and radiation-resistant memory chips which provide more memory storage while being smaller compared to memory chips… »

One Comment2 December 2011

tum-bioelectronics-graphene-based-transistor-arrayResearch that could lead to compensation for some sort of neural damage, or monitor how our bodies function, may seem like something you see in science fiction. However, bioelectronic applications could get a step closer because a team of researchers from the Technical University of Munich and the Juelich Research Center developed a graphene-based transistor… »

Researchers found extraordinary adhesion properties of graphene

By Damir Beciri
23 August 2011

graphene-model-array-1A group of researchers at the University of Colorado Boulder (CU-Boulder) discovered that the extreme flexibility of graphene allows it to conform to the shape of the smoothest surfaces. Its powerful adhesion qualities are expected to help guide the development of graphene manufacturing and of graphene-based mechanical devices such as resonators and gas separation membranes…. »

Graphene paper – thin as paper and ten times stronger than steel

By Rob Aid
One Comment24 April 2011

flexible-graphene-paper-ali-r-ranjbartoreh-in-the-labUniversity of Technology Sydney (UTS) researchers have developed a composite material based on graphite called graphene paper (GP), and it is thin as paper and ten times stronger than steel. Researchers at UTS have successfully milled the raw graphite by purifying and filtering it with chemicals to reshape and reform it into nano-structured configurations which… »

Two methods to produce graphene nanoribbons

By Damir Beciri
11 May 2009

nanoribbon.jpgYou remember we wrote about carbon nanotubes (CNTs) in one of our previous articles? Two groups of researchers have found ways to unfold CNTs in order to make nanoribbons of graphene. The experts claim that the development could point the way towards a new generation of electronics, including computer chips that are faster and tinier… »
