Gamma irradiation has been applied as an efficient and inexpensive method for the sterilization of nuts years. However, along with benefits such treatment, negative effects are possible because formation reactive oxygen species a toxic effect on important biologically active substances. Because scarce contradictory information in literature about gamma-irradiated almonds, aim our work was examination lipid changes, antioxidant activity, oxidative stability almonds treated by 10 25 kGy gamma...
Developing efficient strategies for VOC emission abatement is an urgent task protection of the environment and human health. Complete catalytic oxidation exhibits advantages, making it effective, environmentally friendly, economically profitable approach elimination. Pd-based catalysts are known as highly active hydrocarbon oxidation. The nature carrier materials particular importance because may affect activity by changing physicochemical properties palladium species. In this work, Al2O3,...
The irradiation by gamma-rays is a widely used technique for disinfection in the pharmaceutical and cosmetic industries. In view of growing concerns consumers about this technique, further investigation effects radiation required. work electron paramagnetic resonance (EPR) spectroscopy was applied to study free radicals irradiated horse chestnut (Aesculus hippocastanum L.) seeds evaluate radical scavenging activity (FRSA) using stable DPPH radical. order antiradical potential,...
The present work represented results from a comprehensive study of free radicals and the antioxidant properties irradiated walnuts. effects gamma irradiation on radical generation their stability, as well activity in walnuts, were investigated by Electron Paramagnetic Resonance (EPR) spectroscopy, Oxygen Radical Absorbance Capacity (ORAC), Hydroxyl Antioxidant (HORAC) assays. Walnut samples using 60Co at two different doses: 10 25 kGy. As marker for identification high-energy radiation...
Lactobacillus species are widely recognized for their probiotic potential, focusing on mechanisms of health benefits and protection. Here we conducted an in vitro investigation the potential with a role microbiome homeostasis four strains: Lactiplantibacillus plantarum L6 F53, Ligilactobacillus salivarius 1, helveticus 611. A broad spectrum antibacterial antifungal activity was determined. The strain-specific inhibition Staphylococcus aureus, Streptococcus mutans, Escherichia coli,...
CuFeS2/TiO2 nanocomposite has been prepared by a simple, low-cost mechanochemical route to assess its visible-light-driven photocatalytic efficiency in Methyl Orange azo dye decolorization. The structural and microstructural characterization was studied using X-ray diffraction high-resolution transmission electron microscopy. presence of both components the composite partial anatase-to-rutile phase transformation proven diffraction. Both exhibit crystallite size below 10 nm. phases range...
The water-gas shift (WGS) reaction is a well-known industrial process used for the production of hydrogen. During last few decades, it has attracted renewed attention due to need high-purity hydrogen fuel-cell processing systems. aim present study was develop cost-effective and catalytically efficient formulation that combined advantageous properties transition metal oxides gold nanoparticles. Alumina-supported copper- manganese mixed were prepared by wet impregnation....
Increased levels and detrimental effects of volatile organic compounds (VOCs) stimulate research efforts to develop catalysts with high efficiency in complete hydrocarbon oxidation. This work is focused on the oxidation benzene as a probe reaction for VOCs elimination over alumina-supported CuO-CeO2 mixed oxide promoted by gold. The molecule most stable among aromatic hydrocarbons toxic often carcinogenic known BTEX (benzene, toluene, ethylbenzene, xylenes) owing symmetry stability ring. Use...
