Toward making lithium-sulfur batteries a commercial reality for a bigger energy punch

19-09-2014

A fevered search for the next great high-energy, rechargeable battery technology is on. Scientists are now reporting they have overcome key obstacles toward making lithium-sulfur (Li-S) batteries, which have the potential to leave today's lithium-ion technology in the dust. Their study appears in ...

In the wake of high-profile battery fires, a safer approach emerges

16-05-2014

As news reports of lithium-ion battery (LIB) fires in Boeing Dreamliner planes and Tesla electric cars remind us, these batteries — which are in everyday portable devices, like tablets and smartphones — have their downsides. Now, scientists have designed a safer kind of lithium battery component ...

New smart coating could make oil-spill cleanup faster and more efficient

16-05-2014

In the wake of recent off-shore oil spills, and with the growing popularity of "fracking" — in which water is used to release oil and gas from shale — there's a need for easy, quick ways to separate oil and water. Now, scientists have developed coatings that can do just that. Their report on the ...

How to avoid water wars between 'fracking' industry and residents

25-04-2014

The shale gas boom has transformed the energy landscape in the U.S., but in some drier locations, it could cause conflict among the energy industry, residents and agricultural interests over already-scarce water resources, say researchers. They add that degraded water quality is a potential risk ...

Researchers question emergency water treatment guidelines

22-04-2014

The Environmental Protection Agency's (EPA's) recommendations for treating water after a natural disaster or other emergencies call for more chlorine bleach than is necessary to kill disease-causing pathogens and are often impractical to carry out, a new study has found. The authors of the ...

A greener source of polyester -- cork trees

22-04-2014

On the scale of earth-friendly materials, you'd be hard pressed to find two that are farther apart than polyester (not at all) and cork (very). In an unexpected twist, however, scientists are figuring out how to extract a natural, waterproof, antibacterial version of the first material from the ...

Recycling astronaut urine for energy and drinking water

10-04-2014

On the less glamorous side of space exploration, there's the more practical problem of waste — in particular, what to do with astronaut pee. But rather than ejecting it into space, scientists are developing a new technique that can turn this waste burden into a boon by converting it into fuel and ...
