	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. Detailed record
	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. Detailed record
	Crystallization study of Na-Gd phosphate glasses by non-isothermal DTA Nitsch, Karel ; Kožíšek, Zdeněk ; Rodová, Miroslava Crystallization kinetics of glass with nominal composition of Ce:NaGd(PO.sub.3./sub.).sub.4./sub. were studied using non-isothermal DTA in order to study its thermal stability. Detailed record
	Je vhodné použít standardní model nukleace v konečných systémech? Kožíšek, Zdeněk ; Demo, Pavel Initial size distribution of nuclei in finite systems plays important role in nucleation process. At low supersaturation our model gives the same results as standard model. At high supersaturation decreases of supersaturation in finite system plays important role and phase transition process differs from standard model. Detailed record
	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. Detailed record
	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. Detailed record
	Kinetika vzniku nové fáze v otevřených a uzavřených systémech Kožíšek, Zdeněk ; Demo, Pavel ; Sveshnikov, Alexey Nucleation process in open and closed system is discussed. Basic characteristics of nucleation process (distribution function of nuclei, nucleation rate and total number of nuclei) are determined by numerical solution of kinetic equations. Detailed record
	Homogenní nukleační rychlost v uzavřeném systému při různých počátečních podmínkách Kožíšek, Zdeněk ; Demo, Pavel ; Sveshnikov, Alexey Nucleation kinetics in a closed system is studied. At lower supersaturations time dependence of nucleation rate has very similar behaviour as in standard nucleation model. At higher supersaturations nucleation rate reaches some extremal value and then decreases with time. Detailed record
	Vybrané modely vzniku a růstu krystalické fáze Kožíšek, Zdeněk Detailed record
	Elektrická vodivost přechlazených tavenin halogenidových solí Sveshnikov, Alexey ; Demo, Pavel ; Kožíšek, Zdeněk ; Nitsch, Karel ; Rodová, Miroslava One of the long standing open problems of materials science and technology is how to produce a macroscopic crystal of required physical and chemical properties under a limited number of conditions adjustable and controlable from the outside. For example, purity of a starting material or temperature imposed on the freezing system may play the role of such controlling parameters Detailed record
