Researchers at The University of Western Australia's have discovered that nano-sized fragments of graphene - sheets of pure carbon - can speed up the rate of chemical reactions.
See-through, one-atom-thick, carbon electrodes powerful tool to study brain disorders
Researchers from the Perelman School of Medicine and School of Engineering at the University of Pennsylvania and The Children's Hospital of Philadelphia have used graphene—a two-dimensional form of carbon ...
New self-assembly method for fabricating graphene nanoribbons
First characterized in 2004, graphene is a two-dimensional material with extraordinary properties. The thickness of just one carbon atom, and hundreds of times faster at conducting heat and charge than silicon, ...
A simple and versatile way to build 3-dimensional materials of the future
Researchers in Japan have developed a novel yet simple technique, called "diffusion driven layer-by-layer assembly," to construct graphene into porous three-dimensional (3D) structures for applications in ...
Graphene proves a long-lasting lubricant
When trying to design a mechanical system to last as long as possible, scientists and engineers have to find ways of overcoming friction. While researchers have found many materials that help to reduce friction, ...
Crumpled graphene could provide an unconventional energy storage
When someone crumples a sheet of paper, that usually means it's about to be thrown away. But researchers have now found that crumpling a piece of graphene "paper"—a material formed by bonding together layers ...
Cheap hybrid outperforms rare metal as fuel-cell catalyst
(Phys.org) —Graphene quantum dots created at Rice University grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, ...
