Experimental and Theoretical Studies on Possibility of Void Filling by Magnesium in Mg-Doped Tetrahedrites.

Tetrahedrites, due to their promising thermoelectric properties, are one of the materials being investigated for use in thermoelectric generators. One problem is the lack of -type tetrahedrites, which would be beneficial for the design of tetrahedrite thermoelectric modules. Preliminary theoretical studies have shown that elements from groups I and II can be introduced into the structural voids of tetrahedrite, acting as donor dopants, and should enable -type conductivity.

Catalysts Based on Strontium Titanate Doped with Ni/Co/Cu for Dry Reforming of Methane.

Two series of strontium titanates doped with Ni, Co, or Cu with general formula of SrTiMeO for Sr-stoichiometric and SrTiMeO for Sr-non-stoichiometric materials (where Me = Ni, Co or Cu and x were 0.02 and 0.06) were obtained by the wet chemical method.
