In situ kinetics study of the accelerated aging of poly(ethylene oxide) using photoDSC
Article Abstract:
The global kinetics of chain scissions resulting from the ultraviolet (UV) light irradiation or from the thermal degradation of a high molecular weight poly(ethylene oxide) (PEO) is studied by using photoDSC. The chain scissions reaction follows a first-order kinetic law for both photo and thermal degradation and the activation energies are found to be identical in both cases, whereas the degradation rate is higher in the case of UV irradiation than in the case of thermoageing.

Visible light sensitive photocatalyst, delafossite structured alpha-AgGaO2
Article Abstract:
A new photocatalyst, sensitive to visible light, is explored from the viewpoints of the electronic structure of the valence bond and the crystal structure. It is found that alpha-AgGaO2 has a comparatively high photocatalytic activity and can decompose 2-propanol via acetone and finally, produce carbon dioxide under visible light irradiation.
