"Besides, I knew it was a good candidate as it already showed an interesting variety of solid forms, either molecular or polymeric, crystalline or amorphous." Sulfur is also one of the most ...

A catalyst made of amorphous molybdenum sulphide not only releases hydrogen during electrolysis of water, but also hydrogen sulphide gas in the initial phase. The sulphur for this had to come from ...

When compressed to 16 GPa, the sulfur dioxide in the crystalline phase went through pressure-induced amorphization and entered the amorphous phase of the molecular state. When further compressed ...

Wang's study in the Journal of Geophysical Research: Planetsfocuses on amorphous sulfur and chlorine salts found by the Curiosity rover at Gale crater on Mars. The chemical signature of these ...

Chattopadhyay. Compared with carbon dots that were doped with all the three elements, those doped with only nitrogen and sulphur were amorphous in nature. “When only nitrogen and sulphur are ...

To create it, the scientists treated amorphous molybdenum sulfide with hydrogen plasma. The plasma treatment removed sulfur atoms, creating sulfur vacancies that act as active sites on the catalyst’s ...
