Structure stability of Ag55 and Ag147 nanoclusters with change in the initial morphology
D.A. Ryzhkova, S.L. Gafner, Yu.Ya. Gafner N.F. Katanov Khakas State University, Abakan, Russia DOI: 10.26456/pcascnn/2021.13.XXX Abstract: This article provides a comparative analysis of thermally induced structural transitions in silver nanoclusters with a change in their initial morphology. The study was execute by the molecular dynamics …
Correlation-spectral analysis of the topography of engineering surfaces at the nanoscale level
V.V. Izmailov, M.V. Novoselova Tver State Technical University, Tver, Russia DOI: 10.26456/pcascnn/2021.13.XXX Abstract: The nanotopography of some typical technical surfaces is investigated and the characteristics of the nanoroughness profile as a random process are experimentally determined – the autocorrelation function and spectral density. It is …
Electron-stimulated desorption of lithium atoms adsorbed on the surface of gold-lithium intermetallide
A thin film of the intermetallic compound LixAuy was obtained at room temperature by deposition Li atoms onto a layer of adsorbed gold on the tungsten surface. The processes of electron-stimulated desorption (ESD) of Li atoms from the surface are investigated. It is shown that …
Preferential attachment with fitness dependent choice
Y.A. Malyshkin Tver State University, Tver, Russia DOI: 10.26456/pcascnn/2021.NN.NNN Original paper Abstract: We study the asymptotic behavior of the maximum degree in the preferential attachment tree model with a choice based on both degree and fitness of a vertex. The preferential attachment models are natural …
Viscometry of nanodisperse magnetic liquids and lubricating oils. 2. Metrological analysis of the device for rheological studies of magnetic nanodisperse liquid media
A.N. Bolotov, O.O. Novikova, V.V. Meshkov Tver State Technical University, Tver, Russia Original paper Abstract: An analysis is carried out of the main sources of methodological errors of the magnetic rotary viscometer. The analysis allowed to improve design and to eliminate critical modes of the …
Viscometry of nanodisperse magnetic liquids and lubricating oils. 1. Instrumentation for rheological studies of magnetic nanodisperse liquid media
A.N. Bolotov, O.O. Novikova Tver State Technical University, Tver, Russia DOI: 10.26456/pcascnn/2021.13.XXX Original paper Abstract: Analysis of the literature sources shows that the existing viscometers are not always and not completely able to provide comprehensive studies of magnetic nanofluids for scientific and practical purposes. Design …
Role of «magic» HCP numbers in the stability of the internal structure of Ag89 and Ag153 nanoclusters
D.A. Ryzhkova, S.L. Gafner, Yu.Ya. Gafner N.F. Katanov Khakas State University, Abakan, Russia DOI: 10.26456/pcascnn/2021.NN.NNN Original paper Abstract: Currently, silver is actively used in microelectronics, mainly due to its high electrical and thermal conductivity. Taking into account the processes of interaction between a metal and …
