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.
