(Phys.org) —By some estimates, continued growth in hydraulic fracturing (or "fracking"/"fraccing") could put the US on the path to self-sufficiency in energy over the next few decades. Yet despite the potential economic ...
(Phys.org)—Why certain catalyst materials work more efficiently when they are surrounded by water instead of a gas phase is unclear. RUB chemists have now gleamed some initial answers from computer simulations. They showed ...

(Phys.org)—Over the past few years, Li-air batteries (more precisely, Li-oxygen batteries) have become attractive due to their theoretical ability to store nearly as much energy per volume as gasoline. The key to this high ...
Certain plants and animals protect themselves against temperatures below freezing with antifreeze proteins. How the larva of the beetle Dendroides canadensis manages to withstand temperatures down to -30 degrees Celsius is ...
