State-driven emissions controls only slightly more expensive

Sometimes, doing things close to home may be more feasible than doing them on a grand scale, even if they cost a bit more. This may be the case for controlling carbon emissions, according to a team of researchers who looked ...

3-D reconstructions of individual nanoparticles

What do you see in the picture above? Merely a precisely-drawn three-dimensional picture of nanoparticles? Far more than that, nanotechnologists will say, due to a new study published in the journal Science. Whether a material ...

Ammonia for fuel cells

Fuel cells are pollution-free power sources that convert chemical energy to electricity with high efficiency and zero emissions. Fuel cell cars, trucks, and buses would allow people to travel long distances with convenient ...
