cze	Detailní studium izotermické krystalizace podchlazené taveniny As2Se3	Izotermická krystalizace podchlazené taveniny As2Se3 byla studována pomocí diferenční skenovací kalorimetrie a popsána za použití klasické nukleační teorie a teorie růstu krystalů. Maximum rychlosti nukleace a růstu krystalů bylo pozorováno přibližně při 235 a 350 stupních celsia.	nukleace; krystalizace; As2Se3; diferenční skenovací kalorimetrie
eng	A detailed study of isothermal crystallization of As2Se3 undercooled liquid	Isothermal crystallization of an As2Se3 undercooled melt was studied by differential scanning calorimetry and described using the classical theory of nucleation and crystal growth. The maximum rate of nucleation and crystal growth was observed to occur at approximately 235 and 350 degrees, respectively. The activation energies of nucleation and crystal growth were determined to be Delta E (D) = 311 kJ mol(-1) and Delta E* = 104 kJ mol(-1), respectively. The temperature dependencies of both the activation free energy of nucleation, Delta G, and the critical diameter, r, were also calculated.	nucleation; crystallization; As2Se3; differential scanning calorimetry
