US researchers have created a 'bath sponge'-like metal device that can store vast amounts of hydrogen in cars at low pressures, as an alternative to heavy storage tanks.

Featherweight Metal Date: January 11, 2006 Source: Fraunhofer-Gesellschaft Summary: Metal foams, full of tiny air bubbles like a sponge cake, are gradually making inroads in industrial applications.

With one use, the sponge filtered lead to below detectable levels. After using the sponge, researchers also were able to successfully recover metals and reuse the sponge for multiple cycles. The new ...

Northwestern University engineers have developed a new sponge that can remove metals — including toxic heavy metals like lead and critical metals like cobalt — from contaminated water, leaving ...
