Hybrid copper-gold nanoparticles convert CO2

Copper -- the stuff of pennies and tea kettles -- is also one of the few metals that can turn carbon dioxide into hydrocarbon fuels with relatively little energy. When fashioned into an electrode and stimulated with voltage, ...

Nanocrystals go bare: Stripping material’s tiny tethers

(PhysOrg.com) -- Researchers with the DOE's Lawrence Berkeley National Laboratory have discovered a universal technique for stripping nanocrystals of tether-like molecules that until now have posed as obstacles for their ...

Crystallizing the switch to hydrogen

Hydrogen gas is an almost infinitely inexhaustible fuel source that emits only clean water during combustion. Switching from hydrocarbon-based transportation to systems powered by state-of-the-art fuel cells therefore seems ...
