Určení koncentrace vápennatých iontů v tuhnoucí cementové pastě s různým vodním součinitelem
Tichá, Petra ; Demo, Pavel ; Hošková, Š. ; Sveshnikov, Alexey ; Kožíšek, Zdeněk
Number density of calcium ions within cement paste was experimentally determined for various water to cement ratios and at different times.
Nukleace pórů v pevných látkách: časová prodleva
Sveshnikov, Alexey ; Demo, Pavel ; Tichá, Petra ; Kožíšek, Zdeněk
We study early stage of formation of voids in solids. Within context of nucleation theory the time lag of this process is estimated.
Vliv počátečního přesycení na nukleaci a růst v uzavřených systémech
Kožíšek, Zdeněk ; Demo, Pavel ; Sveshnikov, Alexey ; Tichá, Petra
Influence of initial supersaturation on the size-distribution of nuclei and growth rate is studied in closed system. Numerical solution of kinetic equations show that depletion of the mother phase plays important role at higher initial supersaturations.
Určení parametrů kvantových teček PbCl.sub.2./sub. v matrici NaCl pomoci optické spektroskopie
Sveshnikov, Alexey ; Demo, Pavel ; Polák, Karel ; Beitlerová, Alena ; Tichá, Petra ; Kožíšek, Zdeněk
Within context of nucleation theory and utilizing optical spectroscopy measurements at various temperatures the basic parameters entering nucleation equation (such as, for example, surface energy, resp. temperature dependent difference in chemical potentials) may be estimated.
Proč se podkritické zárodky rozpadají v nukleujícím systému?
Demo, Pavel ; Tichá, Petra ; Sveshnikov, Alexey ; Kožíšek, Zdeněk
We show that if the clusters flux density of nucleating system is interpreted in the sense of Onsager's nonequilibrium thermodynamics, the clusters being smaller than the so-called critical nucleus grow with negative velocity and, thus, they must dissolve in nucleating system.
