For the first time, scientists have captured how complex molecules change shape when exposed to UV light—an ultra-fast ...

Many biologically important molecules change shape when stimulated by UV radiation. Although this property can also be found ...

Cartoon depiction of the sulfur cycle in different planetary regimes. In Earth-like case (A), atmospheric SO 2 is scrubbed from the atmosphere by wet deposition. In the Venus-like case with high ...

This is mainly owing to the high reactivities of the thiol (sulfur atom bonded to a hydrogen atom) and bromine moieties of o-bromobenzenethiols, compounds which contain a bromine atom attached to ...

unique sulfur atom or molecule involvement in interfacial phenomena; g) descriptions of solid phase or combinatorial methods involving sulfur containing substrates. Submissions pertaining to related ...

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 ...

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 ...

Thiol groups are chemical compounds that contain a sulfur atom bound to a hydrogen atom. Sulfur atoms are much larger than hydrogen atoms, which means the sulfur atom in a thiol has a strong pull ...
