But this week, researchers described a lithium-sulfur battery that still has over 80 percent of its original capacity after 25,000 charge/discharge cycles. All it took was a solid electrolyte that was ...

Thioxanthones are fascinating organic compounds that have found their way into many industrial and everyday applications. In the printing industry, for example, they help inks dry faster when exposed ...

Elemental sulfur from the cathode is converted into polysulfide compounds—composed of sulfur atom chains—some of which can dissolve in the electrolyte. Because of this solubility, a "shuttling ...

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 ...
