Siberian scientists showed by their scientific investigations that brines of Siberian Platform are a very important hydro mineral resource for economical development of the East Russia. Prospects for the integrated mining of the hydromineral resources in R ...
In this thesis, Ni catalysts derived from perovskite-type metal oxides (PMO, general formula ABO3, A=lanthanide or earth alkaline element, B=transition metal) are investigated as a potential class of materials, which are able to overcome thechallenges of c ...
High throughput first-principles calculations were employed to unravel the thermodynamic stability of two sets of hierarchical phases, β′′′P and β′′′S, in Mg-RE (rare-earth) alloys. The β′′′P orderings (with compositions greater than xRE=0.125) are predict ...
This thesis reports on the growth and on the magnetic characterization of nanostructures made of 3d-4d transition metals and rare earths. In all the experiments the nanostructures have been grown by atomic beam epitaxy (ABE) in ultra high vacuum conditions ...
Organic and inorganic lead halogen perovskites, and in particular, CH3NH3PbI3, have during the last years emerged as a class of highly efficient solar cell materials. Herein we introduce metalorganic halogen perovskite materials for energy-relevant applica ...
We present a systematic study of the crystal-field interactions in the LiRF4 (R = Gd, Ho, Er, Tm, and Yb) family of rare-earth magnets. Using detailed inelastic neutron scattering measurements, we have been able to quantify the transition energies and wave ...
In the family of the iron-based superconductors, the REFeAsO-type compounds (with RE being a rare-earth metal) exhibit the highest bulk superconducting transition temperatures (T-c) up to 55 K and thus hold the key to the elusive pairing mechanism. Recentl ...
The change of intensities of optical transitions of atoms, molecules, and their ions in the near field of nanoobjects is of interest for researchers from both basic and applied points of view. The concept of a near field was used as early as the 1960s to s ...
Many efforts have been undertaken in past decades to minimize pollution from municipal solid waste incineration fly ash (MSWI FA). This residue is toxic, because of its high concentration of heavy metals, mainly Pb and Zn. A new method for heavy metals ent ...
We show with DFT calculations within the COSMO framework that the wetting energy of clean or hydroxylated anatase TiO2 surfaces is strongly enhanced by Ca deposition at low coverage. Two mechanisms contribute to this behavior: the ionic character of Ca ads ...
