(PhysOrg.com) -- Researchers in Sweden have been liquidizing thousands of specimens of a common North American jellyfish to extract a protein that could be used in microscopic fuel cells.
(Phys.org) —Most batteries, supercapacitors, and other energy storage devices are based on a sandwich structure, where two electrodes face each other and the charge flows between them. However, when these structures are ...
Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a unique new twist to the story of graphene, sheets of pure carbon just one atom thick, and in the ...
