Substitution mechanisms in In-, Au-, and Cu-bearing sphalerites studied by X-ray absorption spectroscopy of synthetic compounds and natural minerals

Filimonova O.; Trigub A.; Tonkacheev D.; Nickolsky M.; Kvashnina K.; Chareev D.; Chaplygin I.; Kovalchuk E.; Lafuerza S.; Tagirov B. (2019)

© 2019 Mineralogical Society of Great Britain and Ireland. Sphalerite is the main source of In- A 'critical' metal widely used in high-tech electronics. In this mineral the concentration of In is commonly correlated directly ...
The charge state of pt in binary compounds and synthetic minerals determined by x-ray absorption spectroscopy and quantum chemical calculations

Evstigneeva P.V.; Trigub A.L.; Chareev D.A.; Nickolsky M.S.; Tagirov B.R. (2021)

The binary synthetic compounds of Pt with chalcogens (O, S, Se, Te), pnictogens (As, Sb, Bi), and intermetallic compounds with Ga, In, and Sn of various stoichiometry were studied via X-ray absorption spectroscopy (XAS). ...
