Rheological properties and UV photo-oxidation of montmorillonite-filled random propylene–ethylene copolymers
(Springer, 2022-05-05)
Random propylene–ethylene copolymers (RPC) are a type of polyolefin in increasing demand, mainly for packaging, due to its high impact resistance, large durability as well as high transparency and flexibility. The present ...
Ceria Promotion of Acetaldehyde Photo-oxidation in a TiO2-based Catalyst: a Spectroscopic and Kinetic Study
(Royal Society of Chemistry, 2015-01)
A spectroscopic and kinetic study of the photo-oxidation of acetaldehyde with a CeO2-TiO2 composite catalyst is presented. Both UV and visible illumination conditions were tested. The study focuses on analysing the role ...
Photo-damage, photo-protection and age-related macular degeneration
(Royal Society of Chemistry, 2015-07)
Age-related macular degeneration (AMD) is a degenerative retinal disease that causes blindness in people 60-65 years and older, with the highest prevalence appearing in people 90 years-old or more. Epidemiological estimates ...
Increased biodegradability of the fungicide imazalil after photo-Fenton treatment in solar pilot plant
(Elsevier, 2019-04)
Wastewater containing pesticides released to water courses without any previous treatment produces an extremely negative impact into the environment, causing concern among the population and authorities. Imazalil (IMZ) is ...
Combining ZVI reduction with photo-Fenton process for the removal of persistent pollutants
(Elsevier Science Sa, 2017-02)
An iron-based photochemical process able to act via reductive and oxidative stages by tuning experimental conditions has been explored. In a first step, zero-valent iron (ZVI), added as steel wool, was used to reduce those ...
Photoreactor Modeling: Applications to Advanced Oxidation Processes
(Berkeley Electronic Press, 2008-05)
A general methodology for photoreactor analysis and design based on the fundamentals of chemical reaction engineering and radiative transfer in participating media is presented. Three applications in the field of advanced ...
Oxygen uptake in the vitamin B2-sensitized photo-oxidation of tyrosine and tryptophan in the presence of uracil: Kinetics and mechanism
(Wiley Blackwell Publishing, Inc, 2009-09)
Considering the significance of visible light-promoted reactions in complex biological media, the photo-oxidation of the amino acids (AAs) tyrosine (tyr) and tryptophan (trp) was studied in the presence of the naturally ...
Atmospheric Photo-oxidation of Diethyl Carbonate: Kinetics, Products, and Reaction Mechanism
(American Chemical Society, 2020-01)
The rate coefficient for the gas phase of diethyl carbonate with chlorine atoms has been determined at 298 K using a relative method, employing ethyl formate and ethyl acetate as reference compounds. The experimental value, ...
Influence of pH and micellar systems on the sensitized photo-oxidation of bovine serum albumin
(John Wiley & Sons Ltd, 2019-02)
Photosensitized oxidation of bovine serum albumin (BSA), by using perinaphtenone as a sensitizer, has been studied at pH 7.4 and 11. The selected sensitizer does not present ground-state complexation with BSA and ensures ...
