Chemical reactions occur when elements or compounds combine and create new compounds. Elements are substances that contain only one type of atom and are represented by unique symbols on the periodic ...

Photosynthesis in nature uses the CaMn4O5 cluster as the oxygen-evolving center to catalyze the water oxidation efficiently in photosystem II (PS II). Synergistic effect among the multi-metal centers ...

WE have made a preliminary survey of the principal respects in which the reaction of deuterium with oxygen differs from that of ordinary hydrogen. The deuterium was prepared by the nearly quantitative ...

Fukuoka, Japan - Hydrogen gas is a promising "green" fuel. The lightest chemical element, hydrogen is an efficient energy store and could potentially replace gasoline in vehicles. However, the element ...

Electrical current is applied to water containing Na2SO4 as an electrolyte. The water is converted into gaseous H2 and O2 at the electrodes. Attach one alligator clip from the battery pack to each ...

A team of researchers has found one of the most effective catalysts ever discovered for splitting oxygen atoms from water molecules -- a key reaction for advanced energy-storage systems, including ...

The electrolytic film produced at Rice and tested at Houston is a three-layer structure of nickel, graphene and a compound of iron, manganese and phosphorus. The foamy nickel gives the film a large ...

Chemists Joel Rosenthal and Daniel G. Nocera of the Massachusetts Institute of Technology provide this answer. When molecular hydrogen (H 2) and oxygen (O 2) are combined and allowed to react together ...
