Photooxidation of 9-anthraldehyde catalyzed by gold nanoparticles: Solution and single nanoparticle studies using fluorescence lifetime imaging
(American Chemical Society, 2012-11)
The photooxidation of 9-anthraldehyde can be catalyzed by colloidal Au nanoparticles (AuNP) or diamond-supported Au nanoparticles (AuNCD) by using LED excitation at 530 nm. Visible irradiation of the plasmon band of AuNP ...
Sensitized photooxidation of thyroidal hormones. Evidence for heavy atom effect on singlet molecular oxygen [O2(1Δ g)]-mediated photoreactions
(Wiley Blackwell Publishing, Inc, 2005-03)
Thyronine derivatives are essential indicators of thyroid gland diseases in clinical diagnosis and are currently used as standards for developing ordinary biochemical assays. Photo-oxidation of gland hormones of the thyronine ...
Photooxidation of Di-tert-butyl Malonate in the Presence and Absence of Nitrogen Dioxide
(American Chemical Society, 2016-10-06)
The rate constant for the reaction of di-tert-butyl malonate (DTBM) with chlorine atoms in the gas phase was measured using cyclohexane and pentane as references. The measurements lead to a value of (1.5 ± 0.1) × 10-10 cm3 ...
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 ...
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 ...
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 ...
Kinetics studies of 5-methyl-2-hexanol, 2,2-dimethyl-3-hexanol, and 2,4,4-trimethyl-1-pentanol with chlorine atoms: Photooxidation mechanism of 2,4,4-trimethyl-1-pentanol
(John Wiley & Sons Inc, 2020-01)
The rate constants for the reaction between chlorine atoms and either 5-methyl-2-hexanol, 2,2-dimethyl-3-hexanol, or 2,4,4-trimethyl-1-pentanol at 298 K were determined using the relative method with 2-butanol and 1-pentanol ...
Superoxide dismutase and glutathione reductase overexpression in wheat protoplast: photooxidative stress tolerance and changes in cellular redox state
(Springer, 2008-08-26)
In previous works, we have established a correlation between antioxidant system response and tolerance to drought, osmotic stress and photooxidative stress of different wheat cultivars with contrasting drought tolerance. ...
Riboflavin-Mediated photooxidation of gold nanoparticles and its effect on the inactivation of bacteria
(American Chemical Society, 2020-07)
Photodynamic inactivation (PDI) of microorganisms, based on the ability of photosensitizers to produce reactive oxygen species (ROS) under adequate irradiation, emerges as a promising technique to face the increasing ...
OH-Initiated Photooxidations of 1-Pentene and 2-Methyl-2-propen-1-ol: Mechanism and Yields of the PrimaryCarbonyl Products
(Wiley VCH Verlag, 2014-12)
The products of the gas-phase reactions of OH radicals with 1-pentene and 2-methyl-2-propen-1-ol (221MPO) at T=298±2 K and atmospheric pressure were investigated by using a 4500 L atmospheric simulation chamber that was ...
