The riboflavin-photosensitized degradation of the uv-absorbing azo dye-metabolites Benzidine and o-Tolidine. Kinetic and mechanistic aspects
(Elsevier Science Sa, 2017-07)
The visible-light-promoted photodegradation of two carcinogenic primary azo-dye metabolites (BZ-C), represented by the colourless water-contaminants Benzidine (BZ) and o-Tolidine (OT), was studied in water-methanol solution. ...
Application of Novel Fulvic Acid-Coated Magnetite Nanoparticles for CO2−-Mediated Photoreduction of Cr(VI)
(Springer, 2018-02)
We here isolate fulvic acids from vermicompost to prepare and characterize novel fulvic acid-coated magnetite nanoparticles. UV-A irradiation of suspensions of the nanoparticles under different experimental conditions led ...
Fabrication of UV responsive micelles-containing multilayers and their influence on cell adhesion
(Science in China Press, 2018-01)
Multilayers incorporated with stimuli-responsive substances by means of layer-by-layer (LbL) self-assembly are much attractive due to the advantages of stimuli-responsiveness and potential applications in different fields. ...
Charge-transfer dynamics of fluorescent dye-sensitized electrodes under applied biases
(American Chemical Society, 2015-07)
The development of dye-sensitized solar cells requires an in-depth understanding of the interfacial charge-transfer dynamics that take place between dye sensitizers and semiconductors. Here, we describe a prototype system ...
Products and Mechanism of the Reactions of OH Radicals and Cl Atoms with Methyl Methacrylate (CH2═C(CH3)C(O)OCH3) in the Presence of NOx
(American Chemical Society, 2014-01)
The OH radical and Cl atom initiated photodegradation of methyl methacrylate has been investigated in a 1080 L quartz-glass environmental chamber at 298 ± 2 K and atmospheric pressure of synthetic air using in situ FTIR ...
Solar UV radiation in a changing world: roles of cryosphere-land-water-atmosphere interfaces in global biogeochemical cycles
(Royal Society of Chemistry, 2019-01)
Global change influences biogeochemical cycles within and between environmental compartments (i.e., the cryosphere, terrestrial and aquatic ecosystems, and the atmosphere). A major effect of global change on carbon cycling ...
