We firstly propose a facile, mild and effective thermal-decomposition strategy to prepare high-quality graphene at a low temperature of 300 °C in only 5 min under an ambient atmosphere. Applying the advantage of this strategy that provides an oxidizing atmosphere, pure V(2)O(5)/graphene composite is successfully synthesized and exerts excellent lithium storage properties.

The experiments described in this paper show (I) that the oxidation of SH groups by common oxidizing agents such as ferricyanide and Folin's uric acid reagent is inhibited by cyanide and promoted by copper sulfate, (2) that the SH groups of denatured egg albumin can be oxidized by an equivalent amount of ferricyanide even in the absence of denaturing agents, provided aggregation is avoided, (3)...

in this paper the photocatalytic degradation of the anionic surfactant, linear alkylbenzene sulfonicacid (labsa) was investigated using uv radiation in the presence of tio2. our findingsdemonstrate that various parameters exert their individual influence on the photocatalytic degradationof surfactant in wastewaters. the mentioned parameters have been categorized as follow: the initialph of the ...

AIMS Oxidizing agents such as chlorine dioxide are widely used microbicides, including for disinfection of medical equipment. We isolated a Bacillus subtilis isolate from a washer-disinfector whose vegetative form demonstrated unique resistance to chlorine dioxide (0·03%) and hydrogen peroxide (7·5%). The aim of this study was to understand the mechanisms of resistance expressed by this isolate...

A new synthesis route, based on the silanization of zeolitic seeds, has been applied to prepare nanocrystalline TS-1 zeolite with hierarchical porosity, leading to materials exhibiting high catalytic activity in 1-octene epoxidation with organic hydroperoxides as oxidizing agents.

In this work, the direct C-H functionalization reaction of 1,4-dimethoxybenzene with N-hydroxyphthalimide has been disclosed. A previously unknown product C-O coupling and was obtained. The proceeded under mild conditions, in which a commercially available manganese-based oxidizing agent used for generation phthalimide-N-oxyl radical. obtained compound is promising valuable precursor O-aryl hyd...

Bleach, nitrite, chromate, and hydrogen peroxide-peroxidase are effective urine adulterants used by the illicit drug users to conceal marijuana-positive results. Methods for detecting nitrite and chromate are available. Effects of other oxidizing agents that could possibly be used as adulterants and are difficult to detect or measure are presented in this report. Urine samples containing 40 ng/...

in this study, the chemical factors effect of metal ions, surfactant, oxidizing agents and enzyme inhibitors on the activity of trypsin and chymotrypsin of rainbow trout fry were considered. the results showed that k+ and na+ had not significant decrease on trypsin and chymotrypsin activity than did those from control (p>0.05). ca2+ and mg2+ showed a significant increase in activity of trypsin ...
