This work describes photocatalytic application of γ-alumina (γ-Al2O3) surface-anchored palladium and palladium oxide nanoparticles (Pd-γ-Al2O3 and PdO-γ-Al2O3NPs) synthesized by a novel co-precipitation technique. The palladium(0) NPs (Pd-γ-Al2O3) were formed by calcination of the sample in inert medium, whereas PdO NPs (PdO-γ-Al2O3) were obtained by calcination of the sample in atm. oxygen. As-synthesized Pd-γ-Al2O3 and PdO-γ-Al2O3 NPs are characterized by X-ray diffraction, Fourier transform-IR spectroscopy, field emission SEM and photoluminescence (PL) spectra. The PL spectra of Pd-γ-Al2O3 and PdO-γ-Al2O3 NPs display visible-light emissions from 450 to 500 nm at room temperature This work aims to study the photocatalytic degradation of organic dye pollutants, including bromocresol green (BCG), bromothymol blue, methylene blue and methyl orange using Pd-γ-Al2O3 and PdO-γ-Al2O3 NPs as potential photocatalysts. Exptl. parameters, including the admitting concentration of the organic dye solution, Pd-γ-Al2O3 and PdO-γ-Al2O3 photocatalyst dosage, and pH, were varied to ascertain favorable conditions for photocatalytic degradation The results indicate that the organic dye BCG is completely (100%) degraded in aqueous solution under UV light, compared with the other organic dyes. Furthermore, Pd-γ-Al2O3 NPs showed better photocatalytic performance than PdO-γ-Al2O3 NPs. The possible photocatalytic degradation mechanism of the organic dyes by Pd-γ-Al2O3 and PdO-γ-Al2O3 photocatalysts is proposed. The studies reveal that Pd and PdO NPs anchored on the γ-Al2O3 surface are promising and effective catalysts for photocatalytic degradation of organic dyes.

Category: indole-building-block. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 1,4-Dibromobutane, is researched, Molecular C4H8Br2, CAS is 110-52-1, about Ascorbic acid specifically reduces the misclassification of nonirritating reactive chemicals in the OptiSafe macromolecular eye irritation test. Author is Lebrun, Stewart; Chavez, Sara; Chan, Roxanne; Nguyen, Linda; Jester, James V..

Recently, we showed that the addition of physiol. concentrations of ascorbic acid, a tear antioxidant, to the OptiSafe macromol. eye irritation test reduced the false-pos. (FP) rate for chems. that had reactive chemistries, leading to the formation of reactive oxygen species (ROS) and mol. crosslinking. The purpose of the current study was to 1) increase the number of chems. tested to comprehensibly determine whether the antioxidant-associated reduction in OD is specific to FP chems. associated with ROS chemistries and 2) determine whether the addition of antioxidants interferes with the detection of true pos. (TP) and true neg. (TN) ocular irritants. We report that when ascorbic acid is added to the test reagents, retesting of FP chems. with reactive chemistries show significantly reduced OD values (P < 0.05). Importantly, ascorbic acid had no significant effect on the OD values of TP or TN chems. regardless of chem. reactivity. These findings suggest that supplementation of ascorbic acid in alternative ocular irritation tests may help improve the detection of TN for those commonly misclassified reactive chems.

Author is Furuta, Shohei; Mori, Toshiaki; Yoshigoe, Yusuke; Sekine, Kohei; Kuninobu, Yoichiro.

The authors synthesized novel hexacoordinated organosilicon compounds with two 2-(2-pyridyl)phenyl groups. Single-crystal x-ray structure analyses indicated that Lewis acid-base interactions exist between the Si atom and two N atoms of the pyridine rings, and that hexacoordinated organosilicon compounds have slightly distorted octahedral structures in the solid state. The hexacoordinated organosilicon compounds are stable in air, H2O, heat, acids, and bases. The fluorescent quantum yield increased dramatically and a significant red shift of the maximum fluorescence wavelength was observed with the introduction of amino groups on the 2-(2-pyridyl)phenyl aromatic rings. The fluorescence colors of a hexacoordinated organosilicon compound with two amino groups can be switched by protonation and deprotonation (neutralization) of the amino groups.
