Vanadium (V) is a transition metal that presents in multiple oxidation states and numerous inorganic compounds and is also an ultra-trace element considered to be essential for most living organisms. Despite being one of the lightest metals, V offers high structural strength and good corrosion resistance and thus has been widely adopted for high ...

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 ...

The topic, vanadium nitrogenase, is reviewed with respect to biological characteristics and findings on its structure and functions. Structural models (vanadium complexes containing ligands related to the active center in the iron-vanadium cofactor) and functional models for the reductive protonation of dinitrogen, the activation of alkynes and ...

AbstractVanadium is an ultratrace element, widely distributed in nature, yet with no presently known specific physiological function in mammals. The apparent role of vanadium in regulation of intracellular signaling, as a cofactor of enzymes essential in energy metabolism, and as a possible therapeutic agent in diabetes is of increasing interest as ...

Saccharomyces cerevisiae cells reduce vanadate V(V) to vanadyl V(IV) as a detoxification mechanism. Cells resume growth as V(V) concentration in the medium decreases as a consequence of its reduction to V(IV); the final number of cells is proportional to initial vanadate concentrations.

Vanadium has long been known to mimic or to enhance insulin activity. It was estimated that by the year 2025 about 300 million people would suffer from diabetes mellitus. Diabetic patients are also subject to other pathologies such as nephropathy, arterial and neurodegenerative diseases.
