Orientated ferromagnetic Ni0.89Fe0.11 nanoparticle/polymer nanofibres were made by electrospinning a solution containing iron(III) nitrate nonahydrate, nickel(II) acetate tetrahydrate, polyvinylpyrrolidone, and acetic acid in methanol thermally processed Ar then 95%Ar:5%H2 up to 620 °C. There was distribution nanofibre widths after with wider (average width 440 nm) some thinner 120 nanofibres. ...

Abstract: Despite having a number of advantages, reinforced concrete can suffer rebar corrosion in high–chloride media, resulting in failure of reinforced concrete structures. In this research the corrosion inhibition capability of the mixture of calcium and ammonium nitrate of steel rebar corrosion was investigated in the simulated concrete pore solution. Cyclic polarization and Electroche...

The solubilities and maximum supersaturation concentrations of an amorphous the crystalline tetrahydrate heptahydrate solids disodium guanosine 5'-monophosphate (GMP) in water-methanol mixtures were measured situ by Raman spectroscopy focused beam reflectance measurement. distinct peaks form, hydrates, solution, solvent used for measurements solubility supersaturation. Above 45 °C at methanol f...

Calcium is the 5th most abundant element on earth, and is found in numerous biological tissues, proteins, materials, and increasingly in catalysts. However, due to a number of unfavourable nuclear properties, such as a low magnetogyric ratio, very low natural abundance, and its nuclear electric quadrupole moment, development of solid-state (43)Ca NMR has been constrained relative to similar nuc...

AIM To study the effect of gallium nitrate in the treatment of flare hypercalcemia in rats, bearing mammary tumor with bone metastasis. MATERIALS AND METHODS Female Sprague-Dawley albino rats were used in the study. Animals were divided into 5 groups: normal control; hypercalcemic rats bearing DMBA-induced mammary tumors; flare hypercalcemic animals bearing DMBA-induced mammary tumors (hyperc...
