Abstract
A new method of obtaining the kinetic parameters from thermogravimetric curves has been proposed. The method is simple and applicable to reactions which can not be analyzed by other methods. The effect of the heating rate on thermogravimetric curves has been elucidated, and the master curve of the experimental curves at different heating rates has been derived. The applications of the method to the pyrolyses of calcium oxalate and nylon 6 have been shown ; the results are in good agreement with the reported values. The applicability of the method to other types of thermal analyses has been discussed, and the method of the conversion of the data to other conditions of temperature change has been suggested. From these discussions, the definition of the thermal stability of materials has been criticized.

Vulcanization kinetics of graphene/natural rubber nanocomposites

TL;DR: In this paper, the influence of graphene (GE) on the vulcanization kinetics of natural rubber (NR) with sulfur curing system was investigated in detail for the first time, and it was found that on adding graphene the induction period was remarkably depressed, whereas the rate is enhanced at low graphene loading and then suppressed.

Kinetic analysis of thermoanalytical data by extrapolating to infinite temperature

TL;DR: In this article, the extrapolation of a set of thermoanalytical (TA) curves to infinite temperature is proposed as a possible method to calculate the kinetic parameters of solid-state reactions from the TA curves without assuming a constant heating rate.

Pyrolysis of olive residue and sugar cane bagasse: non-isothermal thermogravimetric kinetic analysis.

TL;DR: It was found that an increase in heating rate resulted in a shift of thermograms to higher temperatures, and Mass loss and mass loss rates were strongly affected by heating rate.

Preparation, thermal properties, and flame retardance of epoxy–silica hybrid resins

TL;DR: A novel epoxy system was developed through the in situ curing of bisphenol A type epoxy and 4,4′-diaminodiphenylmethane with the sol-gel reaction of a phosphorus-containing trimethoxysilane (DOPO-GPTMS) as mentioned in this paper.

Estimating isothermal life from thermogravimetric data

TL;DR: In this paper, the authors presented a method for estimating equivalent isothermal life from thermogravimetric data and for estimating the apparent activation energy for volatilization even though the nature of the kinetic process is unknown.
