Kinetics of thermal degradation and thermal oxidative degradation of poly(p-dioxanone)

European Polymer Journal, 2003
Abstract The kinetics of the thermal degradation and thermal oxidative degradation of poly(p-dioxanone) (PPDO) were investigated by thermogravimetric analysis. Kissinger method, Friedman method, Flynn–Wall–Ozawa method and Coats–Redfern method have been used to determine the activation energies of PPDO degradation. The results showed that the thermal

Thermal Degradation of DNA

DNA and Cell Biology, 2013
In this article, we investigate the thermal degradation of deoxyribonucleic acid (DNA). We find that under dry conditions, complete DNA degradation occurs at above 190°C. In addition, as the boiling temperature of water is pressure dependent, we have investigated the thermal degradation of the DNA in water for different applied partial pressures.

The thermal degradation of estradiol

Biochimica et Biophysica Acta, 1962
Abstract Thermal degradation of purified estradiol between 275 and 375° was found to be a series of low-yield first-order reactions. Up to 317° estrone and hydrogen were identified as residual molecular fragments. Evidence for further dehydrogenations and possible dehydration was also obtained.

Thermally Degradable Ligands for Nanocrystals

ACS Nano, 2010
We exchanged the oleate ligands on as-prepared PbSe/CdSe core/shell nanocrystals with octyldithiocarbamate to enable the removal of insulating ligands by gentle heating. The octyldithiocarbamate ligand could readily be stripped from the surface by heating briefly to temperatures from 140 to 205 degrees C, which is substantially lower than the ...

Thermal degradation of PVC: A review

Waste Management, 2016
This review summarized various chemical recycling methods for PVC, such as pyrolysis, catalytic dechlorination and hydrothermal treatment, with a view to solving the problem of energy crisis and the impact of environmental degradation of PVC. Emphasis was paid on the recent progress on the pyrolysis of PVC, including co-pyrolysis of PVC with biomass ...
