The determination of activation energy from linear heating rate experiments: a comparison of the accuracy of isoconversion methods
TL;DR: In this article, a classification of model-free isoconversion methods for the calculation of activation energies of thermally activated reactions is proposed, by deriving expressions for the main sources of error which includes the inaccuracy in reaction rate measurement, approximations for the temperature integral and inaccuracies in determination of temperature for equivalent fraction transformed.

Modification of the integral isoconversional method to account for variation in the activation energy
TL;DR: Vyazovkin et al. as discussed by the authors used an integration technique that properly accounts for the variation in the activation energy, which was implemented as a modification of the earlier proposed advanced isoconversional method and applied to the thermal decomposition of calcium oxalate monohydrate and ammonium nitrate.
