Previous work [1] has shown that MEMS technology has significant potential to create more compact, higherperforming hardware for chemical oxygen iodine lasers (COIL). In COILs, the laser medium is a flowing gas that must be pumped through the system at high mass flow rates to ensure proper system operation. As a result, compact pumps with high pumping rates are a key element of the COIL system....

The aim of the present work is to investigate an integration of a microbial reaction system for the oxidation of limonene using a psychrotrophic strain with an unconventional oxygenation of the culture. The alternative method for increasing the dissolved oxygen concentration in culture media for biotransformation of R-(+)-limonene by Mortierella minutissima 01 is based on catalase-mediated deco...

Current evidence suggests that O2- and H2O2 injure cells as a result of the generation of a more potent oxidizing species. In addition to O2- and H2O2, the third essential component of the complex that mediates the lethal cell injury is a cellular source of ferric iron. The hypothesis most consistent with all the available data suggests that O2- reduces a cellular source of ferric to ferrous ir...

We demonstrate a microfluidic fuel cell incorporating hydrogen peroxide oxidant. Hydrogen peroxide H2O2 is available at high concentrations, is highly soluble and exhibits a high standard reduction potential. It also enables fuel cell operation where natural convection of air is limited or anaerobic conditions prevail, as in submersible and space applications. As fuel cell performance criticall...

A combined kinetic and diffusion model with an accurate α-dose rate profile was used to radiation induced dissolution of UO2. Previous experimental data were fit the surface site reaction system involving bound hydroxyl radical as intermediate species for both UO2 oxidation catalysed decomposition H2O2. The performance explored in terms sensitivity spatial temporal resolution well simplificatio...

Background: Poly chlorinated biphenyls (PCBs) are a class of chlorinated organic chemicals that do not easily degrade in the environment. This study was conducted to determine the effect of microwave rays, hydrogen peroxide, dioxide titanium and ethanol solvent on the degradation of PCBs. Methods: A 900w domestic MW oven with a fixed frequency of 2450 MHZ was used to provide MW irradiation. R...

In this research, Zn2SiO4 as a support and MnFe2O4 as a main photo-catalyst were individually syn-thesized and MnFe2O4 was fixed on Zn2SiO4 with solid state dispersion method. MnFe2O4 nano pho-to-catalyst was synthesized by co-precipitation method and reflux condition for 12 hours at 85°C in the presence of urea. For identification of catalysts Fourier-transform infrared (FTIR) sp...

Anatase TiO2 is a widely investigated photocatalyst; however, it can only work under ultraviolet (UV) light with wavelengths less than 390 nm (band gap 3.2 eV). Rutile absorb visible at 410 3.0 eV); its photocatalytic activity not high. Herein, we activated rutile TiO2, which was prepared from Evonik P 25 through calcination 800 °C using hydrogen reduction treatment 700 °C. The of the hydrogen-...

In this scientific research work we report a novel method to synthesis Co3O4 nanoparticles via calcinations of cobalt hydroxide which can be conveniently prepared by the Co(NO3 )2.6H2O with different reactants. In order to study the effect of calcination temperature on structure and morphology of the nanoparticles, the calcinations take place at various temperatures (at 300°C, 500°C and 700°C)....
