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.
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.
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.
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.
