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, researchers at ...

Simplicity will out: Novel experiment-based expression explains behavior of unconventional superconductors

(Phys.org)—Superconductivity – perhaps the leading example of emergent quantum behavior in matter – was discovered in 1911 but lacked theoretical explanation for almost five decades. In 1957, John Bardeen, Leon Cooper, and ...

Catalytic gold nanoclusters promise rich chemical yields

(Phys.org) —Old thinking was that gold, while good for jewelry, was not of much use for chemists because it is relatively nonreactive. That changed a decade ago when scientists hit a rich vein of discoveries revealing that ...

Engineers figure out how to make more efficient fuel cells

Solar power and other sources of renewable energy can help combat global warming but they have a drawback: they don't produce energy as predictably as plants powered by oil, coal or natural gas. Solar panels only produce ...
