Topochemical synthesis of anion-intercalated transition metal dichalcogenide superconductor S0.66(2)WS2

We have successfully synthesized bulk single crystals of S0.66(2)WS2 using a topochemical method, confirming the successful intercalation of sulfur into the interlayer space of M-WS2, which induces hole doping.

Mantle oxidation by sulfur drives the formation of giant gold deposits in subduction zones

Oxidation of the sub-arc mantle driven by slab-derived fluids has been hypothesized to contribute to the formation of gold deposits in magmatic arc environments that host the majority of metal resources on Earth.
