Simulations of complex electron paramagnetic resonance spectra for radiation-induced defect centres in advanced ceramic breeder pebbles
(Elsevier, 2023)Advanced ceramic breeder (ACB) pebbles consisting of lithium orthosilicate (Li4SiO4) and the strengthening phase lithium metatitanate (Li2TiO3) are accepted as the European Union’s reference solid-state material for tritium ... -
Programmable material testing device for mechanoluminescence measurements
(Elsevier, 2022)Mechanoluminescent materials transform mechanical energy into visible light. Phenomena could prove to be advantageous to various next-generation monitoring systems employed in the fields of security and healthcare if the ... -
Pair vacancy defects in β-Ga2O3 crystal: Ab initio study
(Elsevier, 2022)Despit many studies dedicated to the defects in β-Ga2O3, information about formation processes of complex “donor-acceptor” defects in β-Ga2O3 and their energetic characteristics is still very scarce. Meanwhile, complex ... -
Low processing temperatures explored in Sb2S3 solar cells by close-spaced sublimation and analysis of bulk and interface related defects
(Elsevier, 2023)Antimony trisulfide (Sb2S3) is a promising photovoltaic absorber, which has so far been fabricated mainly by chemical deposition methods. Despite its aptness for congruent sublimation, less research efforts have been made ... -
Luminescence of AlN:Mn2+ materials: Properties and mechanisms
(Elsevier, 2023)Luminescence processes resulting in 600 nm emission of Mn2+ ions in AlN:Mn ceramics were studied based on investigations of photoluminescence and its excitation spectra, luminescence kinetics and long-lasting luminescence ... -
Luminescence properties and time-resolved spectroscopy of rare-earth doped SrMoO4 single crystals
(Elsevier, 2022)Luminescence properties of nominally pure and doped with Eu3+ and Pr3+ ions SrMoO4 single crystals grown by the Czochralski method have been studied. Thermal quenching of intrinsic emission of pure and doped SrMoO4 single ... -
Evaluation of radiation stability of electron beam irradiated Nafion® and sulfonated poly(ether ether ketone) membranes
(Elsevier, 2022)Proton exchange membranes (PEM), which have been commonly used in fuel cells have raised interest for the application in harsh environments involving ionizing radiation. Therefore, radiation stability and ability to sustain ... -
Enhanced optical properties of yttrium aluminum garnet with the yttrium vanadate impurity phase
(Elsevier, 2022)Yttrium aluminum garnet doped with europium with an additional impurity phase of yttrium vanadate doped europium has been prepared in different ways: synthesized by a sol-gel route and mechanically mixed in a mortar. The ... -
Corrigendum to Evaluation of radiation stability of electron beam irradiated Nafion® and sulfonated poly(ether ether ketone) membranes
(Elsevier, 2022)Proton exchange membranes (PEM), which have been commonly used in fuel cells have raised interest for the application in harsh environments involving ionizing radiation. Therefore, radiation stability and ability to sustain ... -
Arrhenius plots for Li-ion battery ageing as a function of temperature, C-rate, and ageing state – An experimental study
(Elsevier, 2022)We present an extensive analysis of Li-ion battery ageing via Arrhenius plots. The V-shaped Arrhenius plots show minima at an optimum temperature corresponding to the longest cycle-life. The V-shape of the Arrhenius plots ... -
N-Graphene Sheet Stacks/Cu Electrocatalyst for CO2 Reduction to Ethylene
(MDPI, 2022)Renewable energy resources (wind, solar) are unpredictable, so it is wise to store the electricity they generate in an energy carrier X. Various PtX (power to useful energy-intensive raw material such as hydrogen, synthetic ... -
International Conference "Contentious Collections in Central and Eastern Europe: The Legacy of Ethnographic Shows and Beyond", 26–27 October 2023, Institute of Latvian History, University of Latvia
(University of Latvia, 2023)Researchers in history, cultural heritage studies, ethnography and anthropology, art and museology, at different stages of their career are gathered in Riga for the international conference co-organized by the Institute ... -

Body objectified? Phenomenological perspective on patient objectification in teleconsultation
(Springer Nature, 2023-04-08)The global crisis of COVID-19 pandemic has considerably accelerated the use of teleconsultation (consultation between the patient and the doctor via video platforms). While it has some obvious benefits and drawbacks for ... -
Face-to-Face with the Doctor Online: Phenomenological Analysis of Patient Experience of Teleconsultation
(Springer Nature, 2022-11-28)The global crisis of the COVID-19 pandemic has considerably accelerated the adoption of teleconsultation—a form of consultation between patient and health care professional that occurs via videoconferencing platforms. For ... -
