The Thinking of the Thoughtlessness of Evil: Hannah Arendt’s Account on Thinking as Conditioning Against Evil-Doing
(LU Filozofijas un socioloģijas institūts, 2021)Hannah Arendt describes thinking as an undetermined process, i.e., as a process that is not conditioned by any event in the world since it does not follow from any specific event in the world and it is not aimed at any ... -
Time-Dependent Density Functional Theory Calculations of N- and S-Doped TiO2 Nanotube for Water-Splitting Applications
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)On the basis of time-dependent density functional theory (TD-DFT) we performed first-principle calculations to predict optical properties and transition states of pristine, N-and S-doped, and N+S-codoped anatase TiO2 ... -
Time-resolved FDTD and experimental FTIR study of gold micropatch arrays for wavelength-selective mid-infrared optical coupling
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)Infrared radiation reflection and transmission of a single layer of gold micropatch two-dimensional arrays, of patch length ∼1.0 µm and width ∼0.2 µm, have been carefully studied by a finite-difference time-domain (FDTD) ... -
Time-resolved luminescence and excitation spectroscopy of Co-doped Gd3Ga3Al2O12 scintillating crystals
(Nature Research, 2020)Cerium doped Gd3Ga3Al2O12 (GGAG) single crystals as well as GGAG:Ce single crystals co-doped by divalent (Mg2+, Ca2+) and tetravalent (Zr4+, Ti4+) ions have been studied by means of time-resolved luminescence as well as ... -
Topological analysis of chemical bonding in the layered FePSe3 upon pressure-induced phase transitions
(Wiley, 2020)Two pressure-induced phase transitions have been theoretically studied in the layered iron phosphorus triselenide (FePSe3 ). Topological analysis of chemical bonding in FePSe3 has been performed based on the results of ... -
Toward On-Line Slag Composition Analysis: Optical Emissions from Laboratory Electric Arc
(Springer, 2021)Electric arc furnaces and ladle furnaces have an important role in the future of steelmaking where CO 2 emissions have to be mitigated to an acceptable level. One way to address this goal is to optimize and improve the ... -
Towards metal chalcogenide nanowire-based colour-sensitive photodetectors
(Elsevier B.V., 2018)In recent years, nanowires have been shown to exhibit high photosensitivities, and, therefore are of interest in a variety of optoelectronic applications, for example, colour-sensitive photodetectors. In this study, we ... -
Traffic induced air pollution modeling: Scenario analysis for air quality management in street canyon
(Elsevier B.V., 2019)Mathematical models are intensively used in environmental science for various reasons - status quo assessment, statistical modeling, forecasting, and planning, scenario analysis. Traffic flow and related atmospheric pollution ... -

Transition levels of acceptor impurities in ZnO crystals by DFT-LCAO calculations
(Institute of Physics Publishing, 2018)Large scale ab-initio calculations are carried out to study the charge state transition levels of nitrogen and phosphorus impurity defects in zinc oxide crystals using the DFT-LCAO approximation as implemented into the ... -
Treatment of disorder effects in X-ray absorption spectra beyond the conventional approach
(Elsevier Ltd., 2020)The contribution of static and thermal disorder is one of the largest challenges for the accurate determination of the atomic structure from the extended X-ray absorption fine structure (EXAFS). Although there are a number ... -
Triboelectric behaviour of selected MOFs in contact with metals
(Royal Society of Chemistry, 2022)MOFs have been effectively used to magnify the triboelectric charge of polymers. However, so far the individual triboelectric properties and charge transfer mechanisms of MOFs haven't been reported. Triboelectric property ... -
