carbon nanotubes can be either conducting or semiconducting depending on whether there is a "twist" left in the tube structure when a nanosheet is rolled up. On the other hand, tungsten disulfide ...

composed of rolled tungsten disulfide sheets, possess unique properties that make them valuable for uses ranging from energy storage to optical sensors. Unlike carbon nanotubes, which vary between ...

Disulfide bonds (RS-SR ... are critical for promoting carbon-sulfur bond formation. The source of the sulfur for the reaction, and the mechanism of its insertion, are still unresolved and are ...
