Sensitized photo-oxidation of gadusol species mediated by singlet oxygen
(Elsevier Science SA, 2020-12)
Gadusols are efficient nature UV sunscreens with antioxidant capacity. The kinetics of the quenching reactionsof singlet oxygen O2(1Δg) by gadusol species was evaluated in aqueous solution as well as in the presenceof ...
Fe/SBA-15: Characterization and its application to a heterogeneous solar photo-Fenton process in order to decolorize and mineralize an azo dye
(Elsevier, 2020-03)
Fe/SBA-15 catalyst with different iron (Fe) loads (6% and 10% wt.) was synthesized via incipient wetness impregnation. The potential photocatalytic properties were tested using solar radiation, as a novel catalyst in ...
Carbamazepine Degradation Mediated by Light in the Presence of Humic Substances-Coated Magnetite Nanoparticles
(MDPI AG, 2019-09)
The use of iron-based nanomaterials for environmental remediation processes has recently received considerable attention. Here, we employed core-shell magnetite-humic acids nanoparticles as a heterogeneous photosensitizer ...
Simultaneous abatement of organics (2,4-dichlorophenoxyacetic acid) and inactivation of resistant wild and laboratory bacteria strains by photo-induced processes in natural groundwater samples
(Pergamon-Elsevier Science Ltd, 2018-09-01)
Simultaneous abatement of 2,4-dichlorophenoxyacetic acid (2,4-D at 70 µg L−1), Escherichia coli and Klebsiella pneumoniae (laboratory and wild strains) cells from real groundwater samples containing natural iron concentrations ...
Architectured mesoporous materials modified with nickel for alternative energy and environmental applications: Hydrogen storage and photo-Fenton contaminant degradation
(Elsevier Science, 2018-12)
Ni-MCM-41 nanocomposites were prepared by direct hydrothermal synthesis with different Ni contents. Various characterization techniques were conducted in order to study the properties of the materials. H2 storage capacity ...
Novel (NH4)4[NiMo6O24H6]·5H2O – TiO2 composite system: Photo-oxidation of toluene under UV and sunlight-type illumination
(Elsevier Science, 2018-12-20)
A series of composite materials based on titania and growing quantities of the (NH4)4[NiMo6O24H6]·5H2O heteropolyacid (NiMo6 HPA) was tested in the gas-phase toluene photo-oxidation reaction. Materials were characterized ...
Sweet cherry (Prunus avium) fibers extracted from microwave- and steam-blanched recovered fruits: Photo-antioxidant activity in milk proteins
(Elsevier, 2020-10)
Sweet cherries (Prunus avium L.) discarded at harvesting were upgraded as powerful antioxidant fiber powders for food preservation, and their photo-antioxidant effect on milk proteins evaluated. To stabilize the powders ...
Iron cycling during the autocatalytic decomposition of benzoic acid derivatives by Fenton-like and photo-Fenton techniques
(Elsevier Science, 2015-07-21)
In the context of our work on the oxidative degradation of a series of hydroxyl derivatives of benzoic acid (HBAs) by Fenton-like and photo-Fenton processes, we present a comprehensive study of the factors that affect the ...
Continuous treatment of an azo dye based on a combined ZVI/photo-Fenton setup. Process modelling by response surface methodology
(Elsevier, 2020-06)
The performance of a continuous system that sequentially couples a column filled with zero-valent iron with a photo-Fenton reactor was evaluated under mild acidic conditions. Studies were conducted to evaluate the better ...
DNA damage photo-induced by chloroharmine isomers: hydrolysis versus oxidation of nucleobases
(Royal Society of Chemistry, 2018-02)
Photodynamic therapy (PDT) is an emerging clinical treatment currently being used against a wide range of both cancerous and noncancerous diseases. The search for new active photosensitizers as well as the development of ...
