The Fe-Ni-Pb-B alloy nanoparticles was prepared by a solid-solid chemical reaction of ferric trichloride, nickel chloride, lead acetate, and potassium borohydride powders at room temperature. The research results of the ICP and thermal analysis indicate that the resultants are composed of iron, nickel, lead, boron, and PVP, and the component of the alloy is connected with the mole ratio of pota...

The basic biochemistry of the inhibition of cytochrome oxidase by NO is reviewed. Three possible mechanisms that include the binding of NO to the fully reduced Fe(a3)-Cu(B) site, to the semi-reduced Fe(a3)-Cu(B) site, and to the fully oxidized Fe(a3)-Cu(B) site are confronted with the experimental data. Mathematical models are used to facilitate the analysis and to solve puzzling observations c...

Heats of solution in molten 2Pb0.B203 at 973 K are reported for glasses xNaT3+02-(l x)Si02 for T = Fe, Ga. These measurements, combined with previous data for T = Al, B, give a relative measure of the enthalpy of the charge-coupled substitution Si4+ + Na+ + T3+. The heats of solution become more endothermic with increasing x for x S 0.5 and exhibit a maximum near x = 0.5. This indicates an exot...

The coercivity mechanism of Nd-Fe-B thin film samples with and without Nd deposition was investigated by simultaneous chemical and magnetic imaging by means of X-ray magnetic circular dichroism-photoemission electron microscopy. The two Nd-Fe-B thin film samples exhibited almost the same surface morphology and magnetic domain patterns, but their coercive fields were quite different, being 0.98 ...

Glutathione (GSH) serves as the prime thiol in most organisms as its depletion increases antibiotic and metal toxicity, impairs oxidative stress responses, and affects Fe and Fe-S cluster metabolism. Many gram-positive bacteria lack GSH, but instead produce other structurally unrelated yet functionally equivalent thiols. Among those, bacillithiol (BSH) has been recently identified in several lo...
