Researchers at the Institut Charles Sadron, University of Strasbourg in France have made a polymer gel that is able to contract through the action of artificial molecular motors. The effect is similar to the linear motion of a muscle contraction.  This might be the first artificial muscle. When activated by light, these motors twist the […]

University of Manchester (UM) researchers have found that a graphene membrane, which is impermeable to all gases and liquids, can easily allow protons to pass through it. The discovery could revolutionize fuel cells and other hydrogen-based technologies because they require a barrier that only allow protons – hydrogen atoms stripped off their electrons – to […]

Scientists at Ulsan National Institute of Science and Technology (UNIST) in Korea and Karlsruhe Institute of Technology in Germany have developed a new energy conversion and storage system using seawater for the cathode in a fuel cell. We’ve seen that sodium can serve as an alternative to lithium in rechargeable batteries. That’s because the reversible […]

Umeå University reports Swedish and Chinese researchers are showing how a unique nano-alloy composed of palladium nano-islands embedded in tungsten nanoparticles creates a new type of catalyst for fuel cells. The new type of catalyst is highly efficient at oxygen reduction, the most important reaction in hydrogen fuel cells. The team’s paper has been published […]

Rice University scientists combined graphene quantum dots drawn from common anthracite coal with graphene oxide, nitrogen and boron into a catalyst for fuel cells that outperforms the expensive rare earth platinum. In a fuel cell application the graphene quantum dots grab onto graphene platelets like barnacles attach themselves to the hull of a boat. The […]
