Thermal Denaturation of Collagen Analyzed by Isoconversional Method

Macromolecular Bioscience, 2007
AbstractAn isoconversional method is proposed to be used for evaluating activation energy of protein denaturation. Applied to DSC data on collagen denaturation, the method yields an activation energy that decreases throughout the process. The Lumry‐Eyring model gives an explanation for this decrease and affords estimates for the enthalpy of the ...

Isoconversional method in CRTA

Thermochimica Acta, 1997
Abstract This paper applies the advantage of isoconversional method to the new experimental arrangement of controlled rate thermal analysis (CRTA). The CRTA technique leads to a more effective control of heat and mass transfer phenomena such that much greater sensitivity can be achieved.

Isoconversional kinetic analysis of decomposition of nitropyrazoles

Thermochimica Acta, 2012
Abstract The thermal decomposition kinetics of pyrazole, N-nitropyrazole, 3-nitropyrazole and 4-nitropyrazole using TG–DTA technique under nitrogen atmosphere has been investigated. Friedman differential and Flynn–Wall–Ozawa integral methods were used to determine the kinetic parameters.

Thermoset Cure Kinetics by Isoconversional Methods

Journal of Thermal Analysis and Calorimetry, 1999
The curing kinetics of thermosets based on unsaturated polyester resin crosslinked with styrene was studied by differential scanning calorimetry (DSC). The isoconversional kinetic analysis was applied to non-isothermal data. The results obtained show a dependence of the activation energy (Eα) on conversion (α) that proves the existence of a multistep ...

Isoconversional Kinetics by Fast Scanning Calorimetry

2016
Over the past decade the isoconversional methodology has become a major tool for exploring the kinetics of chemical and physical process. This chapter demonstrates that the application area of the isoconversional kinetics expands dramatically when the methodology is combined with fast scanning calorimetry (FSC).

Isoconversional kinetic analysis of resol-clay nanocomposites

Journal of Thermal Analysis and Calorimetry, 2008
The curing kinetics of nanocomposites based on phenolic resol cured with triethylamine (TEA) containing different amounts of organic montmorillonite was analyzed by differential scanning calorimetry. Kissinger-Akahira-Sunose (KAS) model-free kinetics has been applied to correlate the dynamic cure behaviour in the presence of modified montmorillonite ...

Isoconversional Kinetics of Nonisothermal Crystallization of Salts from Solutions

The Journal of Physical Chemistry B, 2016
In this study, differential scanning calorimetry (DSC) has been applied to measure the kinetics of nonisothermal crystallization of potassium nitrate and ammonium perchlorate from unsaturated and saturated aqueous solutions. DSC data have been analyzed by an advanced isoconversional method that demonstrates that the process is represented by negative ...
