First principles evaluation on photocatalytic suitability of 2H structured and [0001] oriented WS2 nanosheets and nanotubes
(Institute of Physics Publishing, 2019)
Pristine WS2 multilayer nanosheets (NSs), which thickness h NS varies from 1 to 12 monolayers (MLs), as well as single- and multi-walled nanotubes (SW and MW NTs) of different chirality, which diameter d NT exceeds 1.9 nm, ...
Finding electron-hole interaction in quantum kinetic framework
(De Gruyter Open Ltd, 2018)
The article presents a quantum kinetic framework to study interacting quantum systems. Having the constituting model Hamiltonians of two-band semiconductor and the photoexcited electron-hole pair, their quantum kinetic ...
First-Principles Modelling of N-Doped Co3O4
(Sciendo, 2018)
N-doped Co3O4 is a promising electrocatalyst. By means of first-principles calculations, various concentrations and spatial arrangements of NO atoms were modelled. Mutual interaction of the dopant atoms was analysed with ...
Kinetic Monte Carlo modeling of Y2O3 nano-cluster formation in radiation resistant matrices
(Elsevier B.V., 2018)
As known, Y2O3 nano-clusters considerably increase radiation resistance of reactor construction materials. To model the nano-cluster formation kinetics, we propose the simplest possible mathematical model and perform kinetic ...
Glass-forming nonsymmetric DWK-dyes with 5,5,5-triphenylpentyl and piparazine moieties for light-amplification studies
(SPIE, 2018)
A series of 2,6-bis-styryl-4H-pyran-4-ylidene fragment containing glass-forming organic compounds with bonded amorphous phase promoting bulky triphenyl moieties through piperazine structural fragment [2-(2-(4-(bis(2-(tri ...
Investigation of precipitate in an austenitic ODS steel containing a carbon-rich process control agent
(Elsevier Ltd, 2018)
Austenitic oxide dispersion strengthened (ODS) steels are one of the candidates as a structural material for high-temperature applications in future power plants. To guarantee the necessary high production yield, the ...
Depth profiles of damage creation and hardening in MgO irradiated with GeV heavy ions
(Elsevier B.V., 2019)
The effect of irradiation with GeV heavy ions (U, Au, Bi) on the structure and mechanical properties of MgO single crystals was studied. The methods of nanoindentation, dislocation mobility, optical absorption and ...
Comparison of LIBS results on ITER-relevant samples obtained by nanosecond and picosecond lasers
(Elsevier Ltd, 2019)
ITER foresees applying laser induced breakdown spectroscopy (LIBS) as a tool for quantitative assessment of fuel retention in the first walls. One open problem related to LIBS application is the choice of the laser type. ...
Comparison of Luminescence in LiGaO2, Al2 O3 -Ga and Al2 O3 -Li Crystals
(Sciendo, 2018)
We have studied luminescence of LiGaO 2 , Al 2 O 3 -Ga and Al 2 O 3 -Li crystals in order to reveal the nature of luminescence centres and mechanisms in these crystals. In Al 2 O 3 -Ga presence of Ga impurities determines ...
Luminescence of F2 and F3 + centres in LiF crystals irradiated with 12 MeV 12C ions
(Institute of Physics Publishing, 2018)
Dependences of the nanohardness and photoluminescence of F 2 and F 3 + centers on the depth in LiF crystals irradiated with 12 MeV 12 C ions to fluences 10 10 -10 15 ions/cm 2 were studied using laser scanning confocal ...
