With the excessive consumption of nonrenewable resources, exploration effective and durable materials is highly sought after in field sustainable energy conversion storage system. In this aspect, metal-organic frameworks (MOFs) are a new class crystalline porous organic-inorganic hybrid materials. MOFs have recently been gaining traction energy-related fields. Owing to coordination flexibility ...

Vanadium, a potent nonselective inhibitor of protein tyrosine phosphatases, has been shown to mimic many of the metabolic actions of insulin both in vivo and in vitro. The mechanism(s) of the effect of vanadium on the decrease in appetite and body weight in Zucker fa/fa rats, an insulin-resistant model, is still unclear. Because insulin may inhibit hypothalamic neuropeptide Y (NPY), which is kn...

The application of metals in biological systems has been a rapidly growing branch science. Vanadium investigated and reported as an anticancer agent. Melanoma is the most aggressive type skin cancer, incidence which increasing annually worldwide. It paramount importance to identify novel pharmacological agents for melanoma treatment. Herein, systematic review publications including “Melanoma Va...

Lignocellulosic biomass has recently received great interest as a renewable source of fuel and chemicals. Among the three major components of non-edible lignocellulose (cellulose, hemicellulose, and lignin), extensive efforts have been made to convert cellulose into ethanol and other biofuels. In contrast, research on the conversion of lignin has been limited to its removal from biomass either ...

A series of vanadia catalysts supported on SBA-15 (V/SBA) with a vanadia (V) content ranging from 1% to 11% were prepared by an incipient wetness method. Their catalytic behavior in the dehydrogenation of isobutane to isobutene with CO2 was examined. The catalysts were characterized by N2 adsorption, X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, and temperatur...

Nanostructured materials lie at the heart of fundamental advances in efficient energy storage and/or conversion, in which surface processes and transport kinetics play determining roles. This Review describes some recent developments in the synthesis and characterization of nanostructured cathode materials, including lithium transition metal oxides, vanadium oxides, manganese oxides, lithium ph...

Vanadium ion is toxic to animals. However, vanadium is also an agent used for chemoprotection against cancers in animals. To understand both the toxic and beneficial effects we studied vanadium distribution in rats. Accumulation of vanadium in the liver nuclei of rats given low doses of compounds in the +4 or +5 oxidation state was greater than in the liver nuclei of rats given high doses of va...

Electronic structures of the vanadium/vanadium-oxide films supported on α-Fe2O3(0001) were studied by using X-ray photoemission spectroscopy. The vanadium films were grown by evaporation of metallic vanadium at room temperature. The as-deposited V had a 3+ oxidation state and the α-Fe2O3(0001) surface was reduced at the initial coverage. After complete reduction of interface iron atoms, metalli...

Vanadium peroxo-citrate complex was used for the first time for synthesis of YVO4:Eu red emission phosphor material by hydrothermal method. It was found that particles size can be efficiently controlled in the range of 60–400 nm by changing concentration of the solution utilized for the hydrothermal process. The nanocrystalline powders of YVO4:Eu prepared at 200°C for 2 h with post-synthesis he...
