Proton transport in graphene shows promise for renewable energy

Researchers at The University of Manchester have discovered another new and unexpected physical effect in graphene – membranes that could be used in devices to artificially mimic photosynthesis. The new findings demonstrated an increase in the rate at which the material conducts protons when it is simply illuminated with sunlight. The ‘photo-proton’ effect, as it has […]

Graphene scaffold could solve lithium battery problems

While lithium metal-based batteries are attractive in theory, practical applications have run into problems ranging from rapid degradation to catastrophic failure. Researchers have tried to overcome these problems by creating a ‘scaffold’ on which lithium ions can be deposited. However, as the volume of lithium ions changes during the charging cycle, expansion can destroy the […]

New graphene-based catalyst for hydrogen production could be a step toward clean fuel

Researchers at UC Santa Cruz South and the China University of Technology have developed a graphene-based nanostructured composite material that shows impressive performance as a catalyst for the electrochemical splitting of water to produce hydrogen. An efficient, low-cost catalyst is essential for realizing the promise of hydrogen as a clean, environmentally friendly fuel.

Water repellent coating that mimics lotus surface developed

Researchers are trying to mimic biological principles to develop new engineering solutions for medicine, industry and the environment. The approach combines life sciences with engineering and the physical sciences. In case of lotus leaf, beaded water droplets readily roll off on slight tilting of the interface. Such super-hydrophobicity of lotus leaf has inspired researchers to […]

Graphene Looks Toward the Stars

Due to its distinctive properties graphene has been held out as a game-changing material for a range of industries and applications. The Graphene Flagship initiative was set up as Europe’s biggest ever multi-stakeholder research initiative, to quite literally shape the future of the technology.
