Structural phase transitions and magnetic superexchange in MIAgIIF3 perovskites at high pressure
Łukasz Wolański, Marvin Metzelaars, Jan van Leusen +2
Pressure induced phase transitions of MIAgIIF3 perovskites where M = K, Rb, Cs, have been predicted theoretically for the first time for pressures up to 100 GPa. The sequence of ph…
Phase transitions and amorphization of M2AgF4 (M = Na, K, Rb) compounds at high pressure
Jakub Gawraczynski, Łukasz Wolanski, Adam Grzelak +3
We report the results of Raman spectroscopy high-pressure studies of alkali metal fluoroargentates (M2AgF4, where M=Na, K, Rb) associated with theoretical and x-ray diffraction stu…
Effect of vanadium catalysts on hydrogen evolution from NaBH4
Piotr Orłowski1, Wojciech Grochala
NaBH4 is a very cheap and hydrogen rich material and a potential hydrogen store. However, high temperature of its thermal decomposition (above 530°C) renders it inapplicable in pra…
Superexchange interactions in AgMF4 (M = Co, Ni, Cu) polymorphs
Mateusz A. Domański, Wojciech Grochala
Magnetic properties of silver(II) compounds have been of interest in recent years. In covalent compounds, the main mechanism of interaction between paramagnetic sites is the supere…
The fate of compound with AgF plus AgO stoichiometry. A theoretical study
Mateusz Domański, Wojciech Grochala
Metal oxyfluorides constitute a broad group of chemical compounds with rich spectrum of crystal structures and properties. Here we predict, based on evolutionary algorithm approach…
Fluorides of silver under large compression
Dominik Kurzydłowski, Mariana Derzsi, Eva Zurek +1
The silver-fluorine phase diagram has been scrutinized as a function of external pressure using theoretical methods. Our results indicate that two novel stoichiometries containing…
