Callibration of capillaries for density measurement of supercooled water
EPJ Web of Conferences, 2015 Density of supercooled water at elevated pressure is interesting because of the strong anomalies which can be explained by existence of a liquid-liquid critical point in the region of supercooled water.

Active Optical Fibers Doped with Ceramic Nanocrystals
Advances in Electrical and Electronic Engineering, 2014 Erbium-doped active optical fiber was successfully prepared by incorporation of ceramic nanocrystals inside a core of optical fiber. Modified chemical vapor deposition was combined with solution-doping approach to preparing preform.

Advanced Engineering Materials, Volume 26, Issue 18, September 2024.In this work, modifications to the colloidal synthesis of Cs4PbBr6 nanoparticles at room temperature are introduced. The introduced modifications enhance the obtained particles’ quantum yield. Furthermore, the synthesized particles are deposited on top of silicon solar cells to investigate the down‐shifting effect of the perovskite material, which ...

Matter and Radiation at Extremes, 2018 Reliable simulations of laser–target interaction on the macroscopic scale are burdened by the fact that the energy transport is very often non-local. This means that the mean-free-path of the transported species is larger than the local gradient scale ...

On the structure, synthesis, and characterization of ultrafast blue-emitting CsPbBr3 nanoplatelets
APL Materials, 2019 Recent developments in medical imaging techniques, in particular, those in time-of-flight positron emission tomography put new challenges on scintillating material performance that cannot be fulfilled by conventional scintillators.

Probing ultrafast laser plasma processes inside solids with resonant small-angle x-ray scattering
Physical Review Research, 2021 Extreme states of matter exist throughout the universe, e.g., inside planetary cores, stars, or astrophysical jets. Such conditions can be generated in the laboratory in the interaction of powerful lasers with solids.

Left hippocampus sparing whole brain radiotherapy (WBRT): A planning study
Biomedical Papers, 2017 Aims: Unilateral sparing of the dominant (left) hippocampus during whole brain radiotherapy (WBRT) could mitigate cognitive decline, especially verbal memory, similar to the widely investigated bilateral hippocampus avoidance (HA-WBRT).

ToyArchitecture: Unsupervised learning of interpretable models of the environment.
PLoS ONE, 2020 Research in Artificial Intelligence (AI) has focused mostly on two extremes: either on small improvements in narrow AI domains, or on universal theoretical frameworks which are often uncomputable, or lack practical implementations.

Evaluacija efikasnosti rotirajućih nikl-titanijumskih instrumenata u preparaciji kanala korenova zuba kompleksne morfologije [PDF]
, 2023 Due to the high flexibility and cutting efficiency, as well as the preservation of the initial form of the root canal, rotary nickel-titanium endodontic instruments are the instruments of choice in endodontic treatment. However, a sudden fracture during preparation is one of the more serious complications, which is most often the result of cyclic ...
