The Fe-Ni-Sb-B amorphous alloy has been prepared by a solid-solid chemical reaction of ferric trichloride, nickel chloride, antimony chloride and potassium borohydride powders at room temperature. The inductive couple plasma study indicates that the resultant is composed of Fe 5.38 %, Ni 56.19 %, Sb 29.02 % and B 0.44 %. The XRD and thermal analysis show that the alloy is a non-strict sense amo...

OBJECTIVE To investigate barriers to increasing fruit and vegetable (f + v) intakes in a large sample of the older population of Northern Ireland (NI), in relation to current intakes. DESIGN The study was conducted using a telephone survey assessing f + v intakes, barriers to increasing intakes and various demographic and lifestyle characteristics. Barriers to increasing intakes were investig...

Acetyl-CoA synthase from Clostridium thermoaceticum (ACS(Ct)) is an alpha(2)beta(2) tetramer containing two novel Ni-X-Fe(4)S(4) active sites (the A and C clusters) and a standard Fe(4)S(4) cluster (the B cluster). The acsA and acsB genes encoding the enzyme were cloned into Escherichia coli strain JM109 and overexpressed at 37(o)C under anaerobic conditions with Ni supplementation. The isolate...

In this study, a nickel-tungsten/amorphous boron composite coating (Ni-W/B) was successfully deposited on carbon steel using the electrodeposition method. Electrodeposition performed by dispersing varying quantities of amorphous (0, 0.5, 1, and 3 g/L) particles in Ni-W electrolytic bath. The microstructure morphology coatings were characterized scanning electron microscope (SEM). electrochemica...

The Ni–Mo alloy system is studied. In contrast to the existing Ni–Mo binary phase diagram that shows three stable compounds, b-Ni4Mo, c-Ni3Mo, and d-NiMo, it is determined that d-NiMo is meta-stable at very low temperatures. It is also discovered that two additional compounds, Ni2Mo and Ni8Mo are stable at 0K. 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.

The crystal and molecular structures of [Ni(Im)6](dtp)2 (Im = imidazole, dtp = O,O′-diphenyldithiophosphate) have been determined by X-ray crystallography. It crystallizes in the triclinic system, space group Pī, with cell parameters a = 9.375 (2), b = 12.324(3), c = 13.285(3) Å, α = 107.86(3), β = 102.28(3), γ = 109.24(3), and Z = 1. The crystal structure of the title compound is built up of d...

In the title complex, [Ni(CH(3)COO)(C(28)H(26)N(4))]ClO(4), the Ni(II) atom is coordinated by two imine N atoms and two pyridine N atoms of the N-[(E)-1-(6-methyl-2-pyrid-yl)methyl-idene]-2-(2-[(E)-1-(6-methyl-2-pyrid-yl)methyl-idene-amino]-pheneth-yl)aniline donor ligand and two O atoms of the acetate ion in a distorted octa-hedral coordination. The average Ni-N and Ni-O bond lengths are 2.131...

The use of metal tolerant plants for the phytostabilization of metal contaminated soil is an area of extensive research and development. In this study the effects of inoculation of Ni-resistant bacterial strains on phytostabilization potential of various plants, including Brassica juncea, Luffa cylindrica and Sorghum halepense, were studied. A Ni-resistant bacterial strain SR28C was isolated fr...

We design a novel nano-gap electrode to measure the current of DNA molecule, by which the current-voltage characteristics of individual native DNA, Ag-DNA and Ni-DNA molecules are obtained, respectively. The results show that the voltage gap of Ag- and Ni-DNA is higher than that of native DNA, and the conductance is lower than native DNA in neutral environment. The structure transition from B- ...

The nonliving biomass of Pseudomonas oleovorans was used for the removal of Nickel and Copper from their single and binary solutions. The optimum conditions such as pH, initial metal ion concentration, contact time and biomass dose were determined experimentally. qmax and ‘b’ values for Ni(II) were 95.6 mg/g and 0.010 and for Cu(II) 137.5 mg/g and 0.008 respectively. The removal of the metals w...
