Study of mullite formation in porcelain stoneware applying isoconversional and IKP methods [PDF]

open access: green, 2010
The growth process of mullite in a porcelain stoneware body has been studied under isoconversional, isokinetic relationship and invariant kinetic parameters. Activation energy for mullite crystallisation of over 589–628 kJ mol−1 and a Ln A over 50–59 min−

Estimation of the overall kinetic parameters of enzyme inactivation using an isoconversional method [PDF]

open access: greenBiophysical Chemistry, 2008
An isoconversional method is proposed in order to calculate the kinetic parameters of enzyme inactivation. The method provides an efficient and low-cost procedure to describe both operational and thermal inactivation. Unlike the ordinary kinetic assays performed at constant enzyme concentration and at various substrate concentrations, the ...

Kinetic Analysis of the Thermal Decomposition of Polymer‐Bonded Explosive Based on PETN: Model‐Fitting Method and Isoconversional Method [PDF]

open access: goldAdvances in Materials Science and Engineering, 2020
This work investigates kinetics and thermal decomposition behaviors of pentaerythritol tetranitrate (PETN) and two polymer-bonded explosive (PBX) samples created from PETN (named as PBX-PN-85 and PBX-PP-85) using the vacuum stability test (VST) and ...

Crystallization kinetics of overlapping phases in Se70Te15Sb15 using isoconversional methods

open access: hybridProgress in Natural Science: Materials International, 2015
AbstractThe crystallization kinetics of Se70Te15Sb15 chalcogenide glass was studied by Differential Scanning Calorimetry (DSC) under non-isothermal conditions. This glass was found to have a double glass transition and double overlapped crystalline phases. The overlapped crystalline phases were successfully separated using the Gaussian fit model.

Isoconversional methods of thermal analysis yield activation energies that lack physical meaning for Turnbull-Fisher kinetics: Case study of crystallization of piperine from the melt

open access: goldChemical Thermodynamics and Thermal Analysis
Differential scanning calorimetry (DSC) is a useful tool for studying the nucleation rate-limited kinetics of crystallization from the melt. However, applying popular isoconversional methods of thermal analysis to such calorimetric data often yields ...

Thermal lifetime prediction of stabilized polymers by isoconversional methods

open access: greenMoldavian Journal of the Physical Sciences, 2007
During the last decade the importance of the isoconversional methods on the thermal characterisation of different samples has grown, due to possibility of predicting the material behaviour and lifetime.

Isoconversional methods to determine the kinetics of crude oils -thermogravimetry approach

open access: greenJournal of Petroleum Science and Engineering, 2018
© 2018 Elsevier B.V. In this research, kinetics of four crude oils from different origins are determined by iso-conversional methods using thermogravimetry data (TGA-DTG). The experiments were performed at three different heating rates (5-10-15 K/min) between 300 and 1200 K.

Thermogravimetric analysis of face mask waste: Kinetic analysis via iso-conversional methods [PDF]

open access: yesMATEC Web of Conferences, 2023
The surge of face mask waste in response to the global pandemic has proven to be a liability to the environment. Microfibers from plastic constituents of the face mask would cause microplastic pollution in the water bodies. Fortunately, these waste could
