Vanadium is a steel-grey, corrosion-resistant metal, which exists in oxidation states ranging from -1 to +5. Metallic vanadium does not occur in nature, and the most common valence states are +3, +4, and +5. The pentavalent form (VO3-) predominates in extracellular body fluids whereas the quadrivalent form (VO+2) is the most common intracellular form ...

We demonstrated in 1985 that vanadium administered in the drinking water to streptozotocin (STZ) diabetic rats restored elevated blood glucose to normal. Subsequent studies have shown that vanadyl sulfate can lower elevated blood glucose, cholesterol and triglycerides in a variety of diabetic models including the STZ diabetic rat, the Zucker fatty rat ...

Vanadium self-diffusion in pure vanadium and in dilute vanadium-iron and vanadium-tantalum alloys
Philosophical Magazine Part B, 1983Abstract Measurements of vanadium self-diffusion have been made over the temperature range 1050–1874°C. The solute enhancement factor b for vanadium self-diffusion has also been measured in dilute vanadium-iron and vanadium-tantalum alloys. These results, together with the authors' previously published results on iron impurity diffusion in vanadium ...

Abstract Static capsule tests were used to investigate the effect of oxygen in sodium on vanadium and vanadium alloys. When unalloyed vanadium in a vanadium capsule was exposed at 600 and 800° C to sodium that contained up to 1500 ppm O, the specimen and capsule gettered all the oxygen.

The nature of the oxidized halogen intermediate in vanadium bromoperoxidase has recently been shown to depend on the nature of the organic substrate. For example, in the presence of indoles, vanadium bromoperoxidase does not release a freely diffusible oxidized halogen intermediate (such as HOBr+/-BR2+/-Br3-).

Urinary vanadium as a biological indicator of exposure to vanadium
International Archives of Occupational and Environmental Health, 1989Vanadium was determined in urine and blood of two workers (Worker Nos. 1 and 2 with direct exposure to vanadium pentoxide) and 13 fellow workers (with indirect or no vanadium exposure), and the results were compared by means of personal and stationary sampling of vanadium in air. Worker No.

Examples of stable 3d transition metal methylidene complexes are extremely rare. Here we report an isolable and stable vanadium methylidene complex, [(PNP)V(=NAr)(=CH2)] (PNP = N[2-PiPr2-4-methylphenyl]-, Ar = 2,6-iPr2C6H3), via H atom transfer (HAT) from [(PNP)V(NHAr)(CH3)] or [(PNP)V(=NAr)(CH3)] using two or one equivalents of the TEMPO radical ...

Diffusion of vanadium in niobium, zirconium and vanadium
Acta Metallurgica, 1968Abstract Diffusion of vanadium has been studied in niobium, zirconium and vanadium crystals using radioactive tracer and residual activity technique. In niobium and alpha zirconium, the diffusion coefficients (cm2/sec) have been given: Dv/Nb(1000°–1400°C) = 2.21 exp (−85,000/RT) and Dv/α-zr(600°–850°C) = 1.12 × 10−8 exp(−22,900/RT) In beta zirconium ...
