(Phys.org)—One of the concerns with using nuclear energy is the management of the waste produced. Much of reactor waste can be recycled, however one byproduct, americium-241 is radioactive, and is responsible for a large ...
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, researchers at ...
