Calculations of temperature-dependent model activation energy distributions

Abstract

Using a novel approach it is possible to determine continuous distributions of process rates in isothermal transitions and to calculate a quasicontinuous distribution of activation energies and their temperature dependencies. The potential of the approach is demonstrated on the analysis of simulated transition isotherms with different types of activation energy distributions. The analysis is extended to isotherms with realistic temperature-dependent activation energy of nucleation as can be expected in (nano) crystallization.
