Aerogel catalyst shows promise for fuel cells
(Phys.org)—Graphene nanoribbons formed into a three-dimensional aerogel and enhanced with boron and nitrogen are excellent catalysts for fuel cells, even in comparison to platinum, according to Rice University ...
Mapping redox switches in cyanobacteria advances use as biofuel
Chemical reactions involving reduction and oxidation, or redox, play a key role in regulating photosynthesis in plants and metabolism in animals and humans, keeping things running on an even keel. Now, in ...
At last, a theory about why Denver is a mile above sea level
Geologists may finally be able to explain why Denver, the Mile High City, is a mile high: water.
Sub-micrometer carbon spheres reduce engine friction as oil additive
Tiny, perfectly smooth carbon spheres added to motor oil have been shown to reduce friction and wear typically seen in engines by as much as 25 percent, suggesting a similar enhancement in fuel economy.
Small quantities of silver can serve as an efficient catalyst to convert aldehydes to acids
A tiny bit of silver, combined with water and air, can convert aldehydes into acids efficiently—instead of the classical methods using stoichiometric amounts of expensive or toxic metal oxidants, according ...
Finding an affordable way to use graphene is the key to its success
Graphene is a remarkably strong material given it's only a single carbon-atom thick. But finding ways to do something with it – that's also affordable too – have always been a challenge.
Oxide/carbon composites could power green metal-air batteries
Electrochemical devices are crucial to a green energy revolution in which clean alternatives replace carbon-based fuels. This revolution requires conversion systems that produce hydrogen from water or rechargeable ...
