Uranium—A Promising Catalyst: The Hydrogenation of Ethene to Ethane

In chemical processes, catalysts are molecules that increase the rate of a reaction. At the end of the reaction, the catalyst is replenished, an important property that allows it to be used in a much smaller amount than the reactants.

Iron With Three Arms

In biological systems, iron-sulfur (Fe-S) clusters act as components of electron transfer proteins. These clusters occur in various different forms, including cubanes (4Fe-4S) and diamond (2Fe-2S) structures. All known iron-sulfur clusters yield high-spin electron configurations, meaning that one electron is
