Imperfect graphene opens door to better fuel cells

The honeycomb structure of pristine graphene is beautiful, but scientists have discovered that if the graphene naturally has a few tiny holes in it, you have a proton-selective membrane that could lead to improved fuel cells.

Nanospheres cooled with light to explore the limits of quantum physics

Scientists have eveloped a new technology which could one day create quantum phenomena in objects far larger than any achieved so far. The team successfully suspended glass particles 400 nanometres across in a vacuum using an electric field, then used lasers to cool them to within a few degrees of absolute zero.

'Smart bandage' detects bed sores before they are visible to doctors

Engineers are developing a new type of bandage that does far more than stanch the bleeding from a paper cut or scraped knee. Thanks to advances in flexible electronics, the researchers have created a new 'smart bandage' that uses electrical currents to detect early tissue damage from pressure ulcers, or bedsores, before they can be seen by human eyes - and while recovery is still possible.

New cheap and efficient electrode for splitting water

Scientists have developed a highly efficient oxygen-producing electrode for splitting water that has the potential to be scaled up for industrial production of the clean energy fuel, hydrogen. The new technology is based on an inexpensive, specially coated foam material that lets the bubbles of oxygen escape quickly.

Constructing integrated graphene-based artificial nacre

Graphene oxide, a water-soluble derivative of graphene with many functional groups on the surface, is one of the best candidates for fabricating bioinspired layered materials, because functional surface groups enable interface designs that can improve the interfacial strength in composites.
