A new technique to produce graphene at room temperature could help pave the way for commercially feasible graphene-based solar cells and light-emitting diodes, large-panel displays, and flexible electronics.
Scientists describe a powerful approach that uses solvated graphene frameworks as the anode material. Assembled in a lithium coin cell, the as-made electrode excelled with capacities surpassing the values of typically used graphite.
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.
Scientists have discovered a high performance cathode material with great promise for use in next generation lithium-sulfur batteries that could one day be used to power mobile devices and electric cars.
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.
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.
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.
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.
