	Development of Materials Science in Research and Education, Book of Abstracts of the 22nd Joint Seminar Kožíšek, Zdeněk ; Nitsch, Karel Topics: - Trends in development of materials research - Education of materials science at the universities - Information about the research programmes of individual institutions - Information on equipment for preparation and characterisation of materials - Results of materials science research Detailed record
	Kinetics of formation of crystalline nuclei on active centers Kožíšek, Zdeněk ; Demo, Pavel ; Sveshnikov, Alexey Nucleation on active centers is studied. We suggested new model: depletion of active centers is taken into account through boundary condition and thus no additional equation is needed in contrary to standard model. Our model describes corectly not only the total number of nuclei, but also nucleation rate and the size distribution of nuclei. Detailed record
	Equilibrium shape of a liquid nucleus on a highly curved surface of a nanofiber Sveshnikov, Alexey ; Demo, Pavel ; Kožíšek, Zdeněk Approximate equilibrium shape of a liquid nucleus on a nanofiber was determined by minimalization of its free energy under condition of the constant volume of the nucleus. The nucleus is stretched in the direction parallel to the nanofiber axis. The deviation of the shape from a sphere is larger for well-wetting cases. Detailed record
	Volumic dependence of nucleation barrier at critical supersaturation Kožíšek, Zdeněk ; Demo, Pavel ; Sveshnikov, Alexey Kinetic equations of nucleation are solved numerically to found conditions, under which first nuclei are formed. Critical supercooling is determined from the size distribution of nuclei. It is shown that nucleation barrier at critical supercooling depends logarithmically on droplet volume. Detailed record
	Kinetics of polymer nucleation on active centers Kožíšek, Zdeněk ; Demo, Pavel ; Sveshnikov, Alexey ; Tichá, Petra We have numerically solved kinetic equations describing formation of nuclei on active centers to determine the total number of nuclei, nucleation rate and the number densities of nuclei near critical size. Results of our model were compared with experimental data for polymer crystal nucleation of polyethylene on nucleation agent. Our model predicts are in good coincidence with experimental data.

	Kritická přesycení v malých objemech Kožíšek, Zdeněk ; Demo, Pavel ; Sveshnikov, Alexey Critical supersaturation is derived from the size distribution of nuclei as a function of volume of mother phase. Detailed record
	Vliv velikosti objemu na růstovou rychlost zárodků Kožíšek, Zdeněk ; Demo, Pavel Growth rate of supercritical clusters is determined from the size distribution function of nuclei. Detailed record
	Glass formation conditions in supercooled molten zinc chloride Rodová, Miroslava ; Kožíšek, Zdeněk ; Nitsch, Karel Solidification of ZnCl2 melt was studied experimentally by methods of thermal analysis and theoretically by construction of TTT curves. Detailed record
	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. Detailed record
	Vliv velikosti objemu na nukleaci a růst Kožíšek, Zdeněk ; Demo, Pavel Volumic influence to the number of nuclei, nucleation rate and the growth rate is studied. Detailed record
