Our aim to establish the metal (Pb, Cd, Cr, Cu and Zn) levels of wild mammalian scat samples deriving from sanctuaries of Western Rajasthan and compare the concentrations between Desert National Park, Jaisalmer and Gajner Wildlife sanctuary, Bikaner. Restrictions on the sampling because of Wildlife Protection Act (1972) prevents taking of samples of living tissues to analyse body burdens of con...

Three Eu(II1) luminescent compounds were separately entrapped in a xerogel porous silica matrix and finely ground particles of it were deposited on a glass support with polyvinylacetate (PVAc) as a binder to build a thin film sensor. These 3 devices were immersed in aqueous solutions of Cu(I1) and the content of this metal was evaluated by emissionquenching experiments. The sensor containing th...

Ten cadmium resistant marine bacterial isolates were isolated from seawater and sediments samples of Hurghada harbour on a seawater nutrient agar medium amended by 25 ppm of cadmium and tested for their resistance to higher cadmium concentrations (up to 200 ppm). The most resistant isolate which was able to grow at 150 ppm was identified on the basis of its morphological, physiological and bioc...

The Corrosion inhibition of an inhibitor namely Copper complex of 1-(8-hydroxy quinolin-2-yl-methyl) thiourea (Cu-HTF) which controls the corrosion of mild steel immersed in an aqueous solution containing 60 ppm Cl has been investigated through electrochemical and mass loss method. The formulation consisting of 60 ppm of Cl and 50 ppm of Cu-HTF offers good inhibition efficiency of 78 %. Polariz...

Plants and plant extracts (PPEs) have gained increasing interest as feed additives and possible replacing antibiotics for pig productions. The effects of dietary Chlorella vulgaris (1%), sodium alginate (0.1%), inulin (1.5%), and a mixture of essential oils (0.04%) supplements on immune response, and bioavailability of some micronutrients (iron − Fe, copper − Cu, manganese − Mn, and zinc − Zn) ...

Nanocrystalline semiconducting thin films of copper sulphide (Cu2S) were deposited by novel chemical route using aqueous solution of 0.1 M copper chloride, 0.05 M thiourea, complexing agent 10% aqueous ammonia (NH3) and hydrazine hydrate. The characterization and gas sensitivity of as deposited Cu2S thin film sensor have been investigated. The as deposited Cu2S thin films were observed to be ve...

We performed in-situ XAS study of N2O decomposition over CuO/CeO2 catalysts. The Cu K-edge and Ce L3-edge XANES EXAFS analyses revealed the dynamic crucial role Cu2+/Cu+ Ce4+/Ce3+ ionic pairs during catalytic reaction. observed initial formation reduced Cu+ Ce3+ species activation in helium atmosphere at 400 °C, while concentration these decreased significantly steady-state nitrous oxide degrad...

Objective: The aim of the current study was to evaluate adverse effects of Zataria multiflora essential oil on epididymal sperm quality, and testicular tissue following experimentally induced copper poisoning in mice. Methods: The study comprised of four different groups of twelve mice as follows: Group N (Normal) and group Cu (Copper) received pure drinking water, while Groups Z (Zataria multi...

Abstract One-dimensional nanofibers can be transformed into hollow structures with larger specific surface area, which contributes to the enhancement of gas adsorption. We firstly fabricated Cu-doped In 2 O 3 (Cu-In ) by electrospinning and calcination for detecting H S. The experimental results show that Cu doping concentration besides operating temperature, concentration, relative humidity gr...
