Masses of the radioactive isotopes Ga, Zn and Cu have been measured at the JYFLTRAP facility with a relative precision of better than 1.8× 10. A QEC value of (9181.07 ± 0.54) keV for the superallowed decay of Ga is obtained from the measured cyclotron frequency ratios of Ga—Zn, Ga—Ni and Zn—Ni ions. The resulting Ft-value supports the validity of the conserved vector current hypothesis (CVC). T...

It has long been recognized that diffusive boundary layers affect the determination of active transport parameters, but this has been largely overlooked in plant physiological research. We studied the short-term uptake of cadmium (Cd), zinc (Zn), and nickel (Ni) by spinach (Spinacia oleracea) and tomato (Lycopersicon esculentum) in solutions with or without metal complexes. At same free ion con...

Organic-inorganic magnetic hybrid materials (MHMs) combine a nonmagnetic and a magnetic component by means of electrostatic interactions or covalent bonds, and notable features can be achieved. Herein, we describe an application of a self-assembled material based on ferrite associated with β-cyclodextrin (Fe-Ni/Zn/βCD) at the nanoscale level. This MHM and pure ferrite (Fe-Ni/Zn) were used as an...

The aim of this paper was to estimate the influence of deposition of N, Mg, P, S, K, Ca, Mn, Fe, Co, Ni, Cu, Zn Cd, and Pb from under canopy in comparison with open space waters on the elemental composition of the moss layer to test the hypothesis that Pleurozium schreberi (Brid.) Mitt. and Hypnum cupressiforme Hedw. growing under the influence of canopy throughfall of Quercus robur contain hig...

Present study consists geochemical variations and spatial distribution of trace elements (Fe, Mn, Cr, Co, Cu, Ni, Pb and Zn) of the ocean floor sediments collected along the continental shelf off East coast Tamil Nadu (Chennai to Velanganni) during the 2009 southwest monsoon period. Results indicate sand dominance with abundant calcareous debris and shell fragments. Normalisation of trace metal...

Compression springs were prepared from Cr-Si high strength spring steel and coated with pure Zn and ZnNi by electroplating process. The effect of baking after electroplating as well as applying an electroless nickel interlayer on the fatigue and fatigue corrosion of the springs was investigated. The results were analyzed using weibull statistical model. A considerable improvement (8%) in fati...

Polycrystalline bulk copper aluminate Cu1-x-yAgxByAlO2 with B = Ni or Zn were prepared by spark plasma sintering and subsequent thermal treatment. The influence of partial substitution of Ag, Ni and Zn for Cu-sites in CuAlO2 on the high temperature thermoelectric properties has been studied. The addition of Ag and Zn was found to enhance the formation of CuAlO2 phase and to increase the electri...

M(2)L(4) molecular capsules self-assembled from M(II) ions (where M = Zn, Ni, and Pd) and bent bidentate ligands constructed from anthracene fluorophores. The Ni(II) and Zn(II) capsules exhibited weak to strong blue emission unlike traditional Pd(II) cages and capsules.

Protection from oxidative damage is sufficiently important that biology has evolved three independent enzymes for hastening superoxide dismutation: the Cu- and Zn-containing superoxide dismutases (Cu,Zn-SODs), the SODs that are specific for Fe or Mn or function with either of the two (Fe-SODs, Mn-SODs or Fe/Mn-SODs), and the SODs that use Ni (Ni-SODs). Despite the overwhelming similarities betw...
