Calcium ions have been shown to enhance the photo-degradation
of tetracycline HCl under simulated sunlight (55), a point of particular relevance given the calcium ion content of saliva, in the situation of coronal leakage.

Forced degradation study was conducted by exposing samples of the drug substance and drug product to various stress conditions of hydrolysis, oxidation, photo-degradation
, and thermal stress; the time and conditions are illustrated in Table 2.
was faster than pure polymer and composite without pro-oxidant till 5% filler content, after which increasing amount of filler did not affect the photo-oxidation behavior.
The Fig shows that the Kinetics of CLF decomposition well fits pseudo first- order reaction rate and photo-degradation
of CLF was enhanced in the presence of TiO2 / Ti catalyst.
In order to assess the photocatalytic performance of the doped and undoped Ti[O.sub.2] samples under visible and UV light irradiation, the photo-degradation
of MB as a model dye has been performed.
Some of the potential problems from containers include sorption, extraction, permeation, photo-degradation
, and polymer modification.
These studies show that chemical bonds break and the lignin content of wood decreases as a consequence of photo-degradation
. New chromophores form as exposure time is increased (George et al.
