A trigon structure formed by submonolayer gadolinium deposition onto Au(111) is revealed as a robust growth template for cobalt nanodot arrays by Frederik Schiller and co-workers in article 1600187. The cobalt nanoislands behave as independent magnetic entities with an out-of-plane easy axis of anisotropy and enhanced magnetic anisotropy values, as compared to other self-organized cobalt nanodo...

a field experiment involving red clover varieties k-39, k-17, una and viola was established on an acidic (phh2o 4.8) soil to evaluate the effects of foliar application of cobalt (a beneficial nutrient for efficient nitrogen fixation) on seed yield, and on seed yield components. the foliar spray of the crop was carried out using cobalt nitrate [co(no3)2] with the treatments: one application at t...

Using electron energy loss spectroscopy, we have probed the spin waves of fcc(100) cobalt after capping with 1–3 atom layers of pseudomorphic nickel or up to 12 atom layers of copper. The intensity decay of the spin wave signal is quantitatively described by the mean-free path of the incident and the scattered electron within the capping layer. The observed spin waves are therefore localized at...

It has been a concern that the cobalt redox cannot give a good performance for the dye-sensitized solar cells when it is used with ruthenium dyes. The electron dynamics measurements clarified the electron loss processes, and clarified the cause. The result indicated the direct interaction between the ruthenium dyes with the cobalt redox, and it reduced the charge injection from the triplet stat...

Cobalt substitutions were investigated in Ni0.4Zn0.4Cu0.2Fe2O4 ferrites, initial complex permeability was then measured from 1 MHz to 1 GHz. It appears that cobalt substitution led to a decrease of the permeability and an increase of the μs×fr factor. As well, it gave to the permeability spectrum a sharp resonance character. We also observed a spin reorientation occuring at a temperature depend...

An experiment was conducted to measure the effects of cobalt supplementation of pregnant heifers grazing pangola grass pastures on lactation and calf growth. Seven pregnant Hereford heifers were used, with three of these receiving a cobalt bullet and grinder four months after insemination. Cobalt supplementation of heifers had no effect on subsequent milk production or composition. However, cal...

Cobalt is a chemical element that has been used for centuries recreationally as pigments for colouring, giving the bluish hue to glass. Cobalt Poisoning can be manifested by a wide array of systemic effects. Cobalt poisoning can be seen as a result of super alloys in orthopaedic implants, ionizing radiation, occupational exposure and rarely as a foam stabilizer in beer. Here in we conduct a rev...

Structurally diverse mononuclear, dinuclear, and tetranuclear cobalt organophosphates and a three-dimensional framework based on a D4R cobalt phosphate are reported. The role of auxiliary ligands in determining the nuclearity of the phosphate clusters has further been established. Reaction of cobalt acetate tetrahydrate with 2,6-di-iso-propylphenylphosphate (dippH2) in methanol or DMSO in the p...

OBJECTIVES The geltape method is a new method for optical measurement of total amount of dust on surfaces. The objectives were to study the potential applicability of this method to measurements of work related cobalt exposure during painting of plates with cobalt dye. METHODS Consecutive series of work related geltape prints were taken from surfaces inside and outside the ventilation cabins ...

manganese and cobalt concentrations in hair and nail were determined by flame atomic absorption spectrophotometer (aas).the mean manganese in hair and nail were 0.54 â± 0.35mg/g and 0.68 â± 0.30mg/g while the mean cobalt in hair and nail were 0.30 â± 0.24mg/g and 0.460.37mg/g respectively. a progressive increase in cobalt concentrations in hair and nails with age indicated no significant differ...
