Different amounts of Ni-doped TiO(2) (Ni = 0.1 to 10%) powders and thin films were prepared by following a conventional coprecipitation and sol-gel dip coating techniques, respectively, at 400 to 800°C, and were thoroughly characterized by means of XRD, FT-IR, FT-Raman, DRS, UV-visible, BET surface area, zeta potential, flat band potential, and photocurrent measurement techniques. Photocatalyti...

In the present stady, thermochemical treatment in H2/NH3 atmosphere was used as a post-treatment for electroless Ni-P coatings on the AISI 4140 steel substrates. High phosphorus (9%) coatings with thicknesses of 2, 24 and 48 m were applied and the effects of the thermochemical treatment on the morphology, structural changes, roughness, hardness and wear resistance of coatings were studied b...

Surfactant protein B (SP-B) is an essential component of pulmonary surfactant. Synthetic dimeric SP-B(1-25) (SP-B(1-25)), a peptide based on the N-terminal domain of human SP-B, efficiently mimics the functional properties of SP-B. The authors investigated the optimum lipid composition for SP-B(1-25) by comparing the effects of natural lung lavage lipids (NLL), a synthetic equivalent of NLL (sy...

ABSTRACT- A pot experiment was conducted to elucidate the effects of single and co-inoculation of maize plant with Bacillus mycoides and Micrococcus roseus, indigenous to HMs contaminated soils, on the plant growth and uptake of essential nutrients and Ni by maize in the soil polluted by 250 and 500 mg Ni kg-1. At each level of Ni contamination, shoot dry weight and nutrients uptake significant...

Coated powder particles composed of a ceramic core and a metallic coating are being considered for plasma spray applications. The goal of using these powders is to produce particulate-reinforced metal-matrix composite coatings. In this work, the feasibility of plasma spray processing in producing these composite coatings is evaluated. A numerical model is presented to analyze the in-flight ther...

The proximate compositions (moisture, protein, ash, fat, crude fiber and carbohydrate) and levels of thirty seven elements (P, Ca, Cu, Mg, Mn, Na, K, Zn, Pb, Bi, Sn, Ti, Si, Tl, Sb, Ba, Se, Sr, S, Ag, Cd, Mo, Ni, Al, As, Be, Co, Cr, Sc, V, W, Zr, B, Ce, Li, Te and U) were determined in thirteen brands infant formulae samples obtained from three developing (Nigeria, South Africa and Venezuela) a...

The title compound, [Li(2)(C(5)H(4)NOS)(2)(C(2)H(6)O)](n), having two formula units in the asymmetric unit, forms infinite chains of Li(2)O(2) rhombi along b, consisting of four independent Li and O atoms. Metal binding to 2-thio-oxo-1,2-dihydro-pyridin-1-olate occurs in a bidentate fashion via O and S, and in a monodentate manner via the N-oxide O atom. π-π Inter-actions between polymeric chai...
