A research team at the Massachusetts Institute of Technology (MIT) have now shown for the first time that light can be used to increase the mobility of ions and improve the performance of such devices. Lithium-ion batteries, fuel cells and many other devices depend on the high mobility of ions in order to work properly. […]

Technical University of Denmark researchers have found a new method to induce the piezoelectric effect in materials that are otherwise not piezoelectric. It can pave the way for new uses and more environmentally friendly materials. Piezoelectricity is used everywhere: Watches, cars, alarms, headphones, pickups for instruments, electric lighters and gas burners. One of the most […]

Los Alamos National Laboratory’s new fuel cell with a higher-rated power density than state-of-the-art fuel cells can operate at 80-160° Celsius. The new cell solves the longstanding problem of overheating, one of the most significant technical barriers to using medium-and heavy-duty fuel cells in transportation vehicles such as trucks and buses. Because current fuel cells […]

For years, researchers believed that the smaller the domain size in a ferroelectric crystal, the greater the piezoelectric properties of the material. However, recent findings by Penn State researchers have raised questions about this standard rule. Piezoelectricity is a material property where a crystal generates electrical charge under an applied mechanical force. This capability enables […]

Researchers at Dalian Maritime University, Marine Engineering College reported they have developed flexible power generators that mimic the way seaweed sways to efficiently convert surface and underwater waves into electricity to power marine-based devices. Ocean waves can be powerful, containing enough energy to push around sand, pebbles and even boulders during storms. These waves, as […]
