A Swiss government research lab has reinvented flash memory using graphene and molybdenite in a way that should be faster, scale smaller, use less energy and yet more flexible than boring old NAND. Molybdenite is MoS2, molybdenum disulfide, which is similar to graphite and also has a lubricating effect. Atomically it is a …
One should of course speak of the sulphur atoms or the molybdenum disulfide molecule. As a chemist my instinctive reaction to someone saying or writing "the sulfide..." is to ask "the sulfide of what?". It is not a molecule independent of what it is bound to because it cannot exist on its own. Where S2 exists independently it does so as a gaseous allotrope of sulphur called "disulfur"
Should he refer to the sulfide ions? Maybe the editor changed ions to atoms.

I saw what you did there :)
.........I had to google that one. As a design principle it is difficult to argue with!
The primary issue facing SSD type storage flash is durability, smaller faster chips are great, but if they don't last then they become pointless.
