The discharge characteristics of silver vanadium oxide (SVO) as a cathode in lithium–silver vanadium oxide (Li–SVO) primary battery was studied under various operating conditions. The cathode yielded a capacity of 260 mAh g at a current density of 0.08 mA cm, although the theoretical capacity of this material is 315 mAh g. The pulse discharge characteristics were studied under conditions that s...

The study investigated photocatalytic water splitting for O₂ production under visible light irradiation using neodymium vanadium oxide (NdVO₄) and vanadium oxide (V₂O₅) hybrid powders. The results in a sacrificial agent of 0.01 M AgNO₃ solution were obtained, and the highest photocatalytic O₂ evolution was 2.63 μmol/h, when the hybrid powders were prepared by mixing Nd and V at a volume ratio o...

The heteronuclear oxo-cluster [VPO4](•+) is generated via electrospray ionization and investigated with respect to both its electronic structure as well as its gas-phase reactivity toward small hydrocarbons, thus permitting a comparison to the well-known vanadium-oxide cation [V2O4](•+). As described in previous studies, the latter oxide exhibits no or just minor reactivity toward small hydroca...

nanostructured iron oxide powder that has been recovered from waste pickling liquor unit of steel industry was studied for oxidation catalytic applications. in this research, the powder was characterized by x-ray diffraction (xrd) and transition electron microscopy (tem) for determination of phase structure, morphology and particle size. furthermore, the specific surface area of the powder was ...

The chromium/vanadium bimetallic Phillips catalysts developed by our research group have been proved to be a promising process to produce bimodal polyethylene using a single-reactor process. The vanadium loading of CrV-1/1, CrV-1/2, and CrV-1/3 has a significant effect on the polymerization activity, product molecular weight (MW), as well as th...

Identifying suitable two-state systems to act as quantum bits or ‘qubits’ is an important first step in any effort to design and build a quantum computer. One approach is to use a voltage to control the direction of electron spins (which can point up or down) in semiconductor quantum dots. However, spin qubits based on molecular magnets could have a number of advantages, including the possibili...

The reaction of gas-phase oxidation of 4-methylpyridine on individual V2O5, binary and ternary vanadium-oxide catalysts was studied. These catalysts were modified by additives of SnO2 and TiO2. It was found that modifying V2O5 leads to increase the activity of binary contacts. Upon transition from binary V2O5<...
