Transparent Insulating Film Could Enable Energy-Efficient Displays

Johns Hopkins materials scientists have found a new use for a chemical compound traditionally viewed as an electrical conductor (a substance that allows electricity to flow through it). By orienting the compound differently, the researchers have turned it into a thin film insulator, which blocks the flow of electricity but can induce large electric currents elsewhere.

Harvesting Energy from Regular, Day-to-Day Motions

Duke University engineers have developed a novel approach that they believe can more efficiently harvest electricity from the motions of everyday life. Although motion is an abundant source of energy, only limited success has been achieved because the devices used only perform well over a narrow band of frequencies.

Battery Battle

A new type of redox flow battery from the Fraunhofer Institute for Chemical Technology (ICT) offers an advantage for electric cars. If the rechargeable batteries are low, the discharged electrolyte fluid can simply be exchanged at the gas station for recharged fluid – as easy as refilling the gas tank.
