Researchers have found one new gold molecule, a catalyst containing exactly 25 gold atoms, that is powerful as well as sophisticated. It catalyzes the conversion of a variety of molecules, including the transformation of poisonous carbon monoxide into harmless carbon dioxide, a reaction that may find application in devices near gas flues or wood-burning stoves.

Engineers have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas. Unlike other water splitters that use precious-metal catalysts, the electrodes are made of inexpensive and abundant nickel and iron.

Such a device could be used for ultra-high-speed and high-resolution imaging in chemistry, biology, materials science and condensed matter physics. For example, in the life sciences, one could view images with resolutions clear enough to see individual carbon atoms, or to discern events such as a chemical reactions that last one quadrillionth of a second or shorter.

Read moreResearchers from NIST have established guidelines for using surface plasmon polaritons (SPPs) to improve absorption in both photovoltaic or photoelectrochemical cells used for energy conversion. In both types of photocells, SPPs have the potential to increase the amount of light absorbed in the active material layer, improving the overall efficiency of light collection in solar energy devices.
