Select persulfate activation processes were demonstrated to initiate oxidation not reliant on sulfate radicals, although the underlying mechanism has yet be identified. This study explored singlet oxygenation and mediated electron transfer as plausible nonradical mechanisms for organic degradation by carbon nanotube (CNT)-activated peroxymonosulfate (PMS). The of furfuryl alcohol (FFA) a oxygen (1O2) indicator kinetic retardation FFA in presence l-histidine azide 1O2 quenchers apparently...
The reductive transformation of Cr(VI) to Cr(III) by H2O2 in ice was compared with that water. reduction significant at −20 °C (ice), whereas the efficiency very low 25 (water). This enhanced observed over a wide range concentration (20–1000 μM), pH (3–11), and freezing temperature (−10 −30 °C). molar ratio consumed [H2O2] reduced [Cr(VI)] close agreement theoretical (stoichiometric) (1.5) for H2O2-mediated through proton-coupled electron transfer (PCET). synergistic increase water...

The effect of As(III) on the photocatalytic degradation phenolic pollutants such as 4-chlorophenol (4-CP) and bisphenol A (BPA) in a suspension platinized TiO2 (Pt/TiO2) was investigated. In presence As(III), 4-CP BPA significantly enhanced, simultaneous oxidation to As(V) also achieved. This positive is attributed adsorption (generated from oxidation) surface Pt/TiO2, which facilitates production free OH radicals ((•)OHf) that are more reactive than surface-bound ((•)OHs) toward pollutants....
An enhancing effect of peroxymonosulfate (PMS) on photocatalytic activity has previously been demonstrated, but the research focus was concentrated primarily extent to which treatment efficiency improved. To further comprehend role PMS, this study examined TiO2 systems in presence PMS for oxidation diverse organics and showed that performance enhancement via addition substrate-dependent. This resulted from involvement multiple oxidants owing dual as an electron acceptor a radical precursor,...
We attempted to obtain a transcriptomic profile of ionizing radiation-responsive genes in Arabidopsis plants using Affymetrix ATH1 whole-genome microarrays. The were irradiated with 200 Gy gamma rays at the early reproduction stage, 33 days after sowing. Rosette leaves harvested during postirradiation period from 36 49 sowing and used for microarray analysis. most remarkable changes genome-wide expression observed 42 (9 irradiation). identified 2165 as gamma-ray inducible 1735 repressible....
Cadmium (Cd) accumulates in the body through contaminated foods or water and causes pathological damage to liver via oxidative stress inflammatory reactions. This study was conducted explore effects of dendropanoxide (DPx) on Cd-induced hepatotoxicity rats. Sprague-Dawley (SD) rats were injected with CdCl2 (7 mg/kg weight) intraperitoneally for 14 days induction dysfunction. The CdCl2-exposed subjected DPx (10 mg/kg) silymarin (50 mg/kg). animals euthanized after 24 h last injection serum...
Oxygen vacancy (OV) as the key site in promoting charge separation and visible-light harvesting WO3 has often been created through thermal annealing. However, this study proposes sequential combination of Pt photodeposition followed by chemical reduction using NaBH4 a room-temperature approach to fabricate platinized oxygen vacant tungsten oxide (Pt/WO3–x). OVs (or low-valence tungsten), detected multispectroscopic techniques, occurred catalytic hydrogenation featuring atomic hydrogen...
New measurements by high-resolution electron-energy-loss spectroscopy confirm the presence of localized film modes for ultrathin epitaxial films nickel on a copper (001) substrate. These modes, predicted recently in lattice-dynamical calculations Chen, Wu, Yao, and Tong [Phys. Rev. B 39, 5617 (1989)] lie above Cu-substrate bands correspond to vibrational motion Ni overlayer. The Rayleigh-mode dispersion overlayers is also reported.
The structural, electronic and dielectric properties of high-quality ultrathin BaTiO3 films were investigated. films, which grown by ozone-assisted molecular beam epitaxy on Nb-doped SrTiO3(001) substrates have thicknesses as low 8 unit cells (u.c.) (3.2 nm), are unreconstructed atomically smooth with large crystalline terraces. A strain-driven transition to three-dimensional (3D) island formation is observed for 13 u.c. thickness (5.2 nm). high structural quality the surfaces, together...
