Researchers bring clean energy a step closer
For nearly half a century, scientists have been trying to replace precious metal catalysts in fuel cells. Now, for the first time, researchers at Case Western Reserve University have shown that an inexpensive metal-free catalyst ...
A long-lasting obstacle of solid oxide fuel cells has been overcome
One of the major drawbacks of carbon-fueled battery cells is the intrinsic presence of CO2, which impedes CO oxidation and, therefore, lowers the energy density of the cell. In the journal Angewandte Chemie, resear ...
Protons fuel graphene prospects
Graphene, impermeable to all gases and liquids, can easily allow protons to pass through it, University of Manchester researchers have found.
Scientists create renewable fossil fuel alternative using bacteria
The development is a step towards commercial production of a source of fuel that could one day provide an alternative to fossil fuels.
