Oxygen-enriched combustion can improve thermal efficiency and reduce CO, unburned hydrocarbons soot emissions in internal engines. There are significant differences the process pollutant between oxygen-enriched air condition. In order to develop an improved understanding of effect oxygen concentration on n-heptane oxidation, jet-stirred reactor oxidation characteristics were experimentally test...
Lead ion of sulfate was studied electrochemically analysis, using cyclic voltammetric technique by glassy carbon electrode (GCE) in normal saline solution (0.9%NaCl). The results of the study have been found oxidation and reduction current peaks of lead ion in normal saline at -550 mV and -650mV respectively. It was studied the electrochemical properties of the redox current peaks of Pb(II) wit...
This work provides an experimental evidence of the photoinduced generation of radical species upon UV irradiation of aqueous suspensions of carbon materials with varied textural, structural and chemical composition. The use of a powerful spectroscopic tool as spin trapping electron spin resonance (ESR) has allowed to detect and identify these radicals (among which are hydroxyl, superoxide and o...
The development of visible-light active photocatalysts is vital to harvest the solar irradiation and build efficient photoelectrochemical devices. Bismuth oxyhalide (BiOCl, BiOBr BiOI) materials stand out due their remarkable properties, e.g., band gap energy can be tuned from 1.9 3.4 eV depends on halide employed. However, hydrothermal synthesis this material class was not properly investigate...
UV treatments are commonly employed for removal of pollutants from water in industrial environments. Introduction a suitable photocatalyst can be beneficial improving the energy efficiency. This involves creating powerful reactive oxygen species that able to degrade pollutants. However, is required have both high surface area (accessible irradiation light source) and mechanically robust. TiO2 w...

BACKGROUND Environmental pollutants are thought to be one of major triggers of atopic dermatitis (AD). OBJECTIVE We attempted to evaluate the clinical effects of environment with low indoor pollutant levels on AD management. METHODS Fifty-one children (mean age 1.7 years) with moderate to severe AD who failed to show improvement with conventional management were recruited. Disease severity ...
