Remarkably, the dissociation resulted in the formation of a neutral but excited sulfur atom, even though multiple electrons were ejected during the cascade. This phenomenon is at first surprising ...

Iron is an element. It is made of only one type of atom: iron atoms. Sulfur is another element. It contains only sulfur atoms, and nothing else, so it is pure. When we mix two different pure ...

Solar cells convert sunlight into clean energy—but if the solar cells themselves are made of toxic materials, it almost ...

New iron and sulfur atom assemblies. Other than the common [2Fe-2S], [3Fe-4S] and [4Fe-4S] clusters of Figure 1, the following structures have been discovered: (i) clusters with larger ...

Surprisingly, the biosynthesis of this simple derivative requires a minimum of four sulfur transfer reactions involving seven proteins. To identify genes required for tRNA modification ...

2-thiouracil and its chemically related active substances have a sulfur atom, which gives the molecules its unusual, medically relevant properties. "Another special feature is that these molecules ...
