Thioxanthone Sensitized Photodegradation of Poly(alkyl methacrylate) Films
(JOHN WILEY & SONS INC, 2010)
The thioxanthone-sensitized photodegradation of poly(alkyl methacrylate) films [alkyl = methyl, ethyl, butyl, and hexyl] was studied using near UV-vis light. The photooxidation process continued even after the total ...
Photodegradation of hydroxylated N-heteroaromatic derivatives in natural-like aquatic environments: A review of kinetic data of pesticide model compounds
(Pergamon-Elsevier Science Ltd, 2005-12)
In the present review, the results published by our group and others related with the study of the kinetic behavior and, in some cases, the mechanism of the dye-promoted photooxygenation of several hydroxypyridines, ...
Effect of the incorporation into unilaminar vesicle on the photodegradation of indoles sensitized by flavins
(SOC CHILENA QUIMICA, 2013)
The Employment of a Removable Chitosan-Derivatized Polymeric Sensitizer in the Photooxidation of Polyhydroxylated Water-Pollutants
(Wiley Blackwell Publishing, Inc, 2014-01)
The known O2(1∆g)-sensitizer system Chitosan bounded Rose Bengal (CH-RB), with Rose Bengal (RB) immobilized by irreversible covalent bonding to the polymer Chitosan (CH), soluble in aquous acidic medium, was employed in ...

(Wiley, 2014-10)
The known O2(1g)-sensitizer system Chitosan bounded Rose Bengal (CH-RB), with Rose Bengal (RB) immobilized by irreversible covalent bonding to the polymer Chitosan (CH), soluble in aquous acidic medium, was employed ...
Protective packaging for light-sensitive foods
(CRC Press - Taylor & Francis Group, 2019)
Consumer expectations and interests in nutritional aspects and visual appearance,when purchasing food, are important factors that should be taken into account toimprove the food industry (Gadioli et al., 2013). Currently, ...
Influence of copper-phthalocyanine on the photodegradation of polycarbonate
(Elsevier Sci LtdOxfordInglaterra, 2006)
Riboflavin sensitized photodegradation of Furaneol in a β-cyclodextrin complex
(Elsevier Science SA, 2021-04-15)
A study on the photodegradation of the widely employed flavoring compound Furaneol (FUR), in the presence of vitamin B2 (Riboflavin, Rf) was carried out, in aqueous and microheterogeneous media. The system as a whole allows ...
Desenvolvimento de filmes finos de organosilicone depositados a plasma para fotoproteção do polipropileno
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus Sorocaba, 2019-02-26)
Polypropylene (PP) is a polymer used industrially on a large scale. However, the PP has limitations in external use due to its sensitivity to photodegradation, when exposed to the elements. This limits the options of use ...
Protection of astaxanthin from photodegradation by its inclusion in hierarchically assembled nano and microstructures with potential as food
(Elsevier, 2018-10)
Astaxanthin is a light sensitive molecule which is already approved as a dietary supplement, with a wide range of biological properties in humans and fishes. In this paper, we provide strategies to photostabilize the pigment ...
