Variability of a Non-Centrosymmetric Tecto-Borosulfate: Introduction of Various Molecular Cations into BiX[B(SO₄)₂]₄ (X  =  H₃O⁺, NO₂ ⁺, NH₄ ⁺, NO⁺). [PDF]

Chemistry
To date, Bi(H3O)[B(SO)2]4 is only the second structure type containing a 3D anion within borosulfate chemistry. In this contribution three more representatives were synthesized, formally replacing oxonium by the molecular cations nitrosonium, nitronium, and ammonium. The structures crystallize homeotypically to the very first compound.

Advances in methods to obtain and characterise room temperature magnetic ZnO [PDF]

, 2015
We report the existence of magnetic order at room temperature in Li-doped ZnO microwires after low energy H+ implantation. The microwires with diameters between 0.3 and 10 μm were prepared by a carbothermal process.

In situ Raman imaging of high-temperature solid-state reactions in the CaSO4–SiO2 system

International Journal of Coal Science & Technology, 2019
The deposition of mineral phases on the heat transfer surfaces of brown coal power plants may have a negative effect on power plant boilers. The paragenesis of these deposits contains information about the actual temperature prevailed during the ...
