Gaining an Edge for Energy Production and Storage

Rice University scientists who want to gain an edge in energy production and storage report they have found it in molybdenum disulfide.  From Wikipedia: “Molybdenum disulfide is the inorganic compound with the formula MoS 2. The compound is classified as a metal dichalcogenide. It is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum.   MoS 2 is relatively unreactive. It is unaffected by dilute acids and oxygen. In appearance and feel,molybdenum disulfide is similar to graphite. It is widely used as a solid lubricant because of its low friction properties and robustness.” Let’s break down one probably unfamiliar term (it was to your editor).  A chalogen is one of the members of the Vla group in the periodic table and includes oxygen, sulfur, selenium, tellurium, and polonium.  Add a more electropositive element to one of those and we get a chalogenide.  Double down and make it a dichalogenide, in this case a material that looks similar to graphene, but more three-dimensional, with three layers because it has slab of molybdenum sandwiched between two …
