Controlling thermal conductivities can improve energy storage

Controlling the flow of heat through materials is important for many technologies. While materials with high and low thermal conductivities are available, materials with variable and reversible thermal conductivities are ...

Clay key to high-temperature supercapacitors

Clay, an abundant and cheap natural material, is a key ingredient in a supercapacitor that can operate at very high temperatures, according to Rice University researchers who have developed such a device.

Chunky mobile devices? Soft graphene could help you downsize

Assuming you are geeky enough to open up any mobile device on the market – a phone, tablet or laptop – the most glaringly obvious component of the device is the battery: it generally consumes up to (if not more than) ...

Electrochemical step towards a better hydrogen storage

Good metal-based systems for hydrogen storage cannot be developed without knowing how this element permeates through metals. Researchers at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw managed ...

New analytical methodology can guide electrode optimization

Using a new analytical methodology—a coupled micro-computed X-ray tomography (MicroCT) and microfluidic-based electrochemical analysis—researchers at the University of Illinois at Urbana-Champaign are gaining new insights ...
