Investigators: M. Majerová, D. Galusek, M. Michálková, A. Talimian, A. Prnová The research was focused on the development of a new type of aluminosilicate glasses and glass-ceramics with luminescent properties. The effect of Bi on the crystallization kinetics of the gelenite (2CaO-Al2O3-SiO2) glass was investigated. The obtained knowledge can be used in the preparation of…

Investigators: M. Škrátek, P. Billik Ag2O nanoparticles are an exceptional material that has great potential for biomedical applications due to its high cytotoxicity. Although the wet chemical synthesis of Ag2O nanoparticles is a particularly simple preparative technique, it is very difficult to obtain Ag2O in a concentrated state because the precipitation rate is difficult to…

Investigators: Jozef Klembara, Miroslav Hain Using modern digital imaging methods – photogrammetric scanning and virtual 3D imaging, the only known specimen of the early eureptile Coelostegus prothales from the Upper Carboniferous of the Czech Republic was described. Using these modern digital 3D imaging methods, new, highly detailed information on the structure of the individual bones…

Investigators: Beáta Ondrušová, Peter Tiňo, Jana Švehlíková This study addresses the non-invasive localization of cardiac abnormalities, specifically premature ventricular contractions (PVCs), through a newly proposed two-stage inversion solution for a dipole cardiac source. One of the inputs for solving the inversion problem is the surface potentials measured using a large number (128) of electrodes placed…

Investigators: Anna Krakovská, Martina Chvosteková, Jozef Jakubík Identifying causal relationships in measured time series is a research topic that we have been working on intensively for several years. This year we have focused on discovering causality in cases where traditional tools such as the Granger test, successful for example in autoregressive processes, are not applicable…

A measuring system for automated measurement of the tilt of the reactor vessel of the third unit was developed in the Department of Optoelectronic Measurement Methods of the Institute of SAV Measurement and in 2022, together with the third unit of the Mochovce nuclear power plant, it is put into continuous operation. This measuring system…

A. Dvurečenskij, A. Cigáň, , M. Škrátek, M. Majerová, J. Maňka In colloids of metal nanoparticles based on high-entropy alloys (HEA-High Entropy Alloys) in imidazolium-based ionic liquids, the properties of three objects meet: ionic liquids, HEA alloys and nanoparticles. Each of them separately exhibits unique properties that have attracted considerable attention in recent decades due…

The measurement and 3D imaging method of high-resolution X-ray microtomography – microCT developed at the SAV Measurement Institute has been successfully used in forensic science. In the close cooperation of ten scientific, university and criminological workplaces, the influence of the action of concentrated acid on the loss of dental mass, various selected dental fillings and…

In 2022 The department of optoelectronic measurement methods of the ÚM SAS was actively involved in solving the problem of multimodal imaging as part of international cooperation, focusing mainly on the fields of biology, paleontology, cultural heritage, mineralogy, and also on material and forensic science. This year, the SAV Measurement Institute participated in the solution…

Investigators: Jana Švehlíková, Anna Přibilová, Ján Zelinka, Beáta Ondrušová, Katarína Kromková, Peter Hlivák, Robert Hatala, Milan Tyšler The input data for localization of the source of premature ventricular activity (PKA) were averaged ECG signals obtained from a 5-20 minute recording of multi-lead ECG measured in 14 patients diagnosed with PKA. During its standard processing, the…
