Vanadium pentoxide (V2O5) is a highly promising material for optoelectronic applications due to its wide optical band gap, significant thermal/chemical stability, and intriguing multichromic properties. Nonetheless, the production of uniform crack-free V2O5 thin films over large areas via conventional deposition methods remain be challenge. In this work, we demonstrate microscopically uniform, ...

Spray pyrolysis technique (SPT) and radio-frequency magnetron sputtering (RF-MS) were used to obtain vanadium oxide (VxOy) layers. The surface morphology was visualized using scanning electron microscopy (SEM) atomic force (AFM). Further, t

Abstract Vanadium pentoxide (V 2 O 5 ) as the cathode material has caused great concern in metal-ion batteries due to diverse valence states of vanadium. However, structural instability and poor electrical ionic conductivity significantly limit its application high-efficiency electrodes. Herein, V nanosheet is directly grown on electrospun carbon nanofibers @CNFs) by a hydrothermal method for s...

Layered-structure nanoribbons with efficient electron transport and short lithium ion insertion lengths are promising candidates for Li battery applications. Here we studied at the single nanostructure level the chemical, structural, and electrical transformations of V2O5 nanoribbons. We found that transformation of V2O5 into the omega-Li3V2O5 phase depends not only on the width but also the th...

To clarify acute toxicity and histopathological changes in the lung after exposure to V2O5 powder, rats (SD, male, n=66) were observed for 4 weeks after an intratracheal administration of V2O5 powder (geometric mean diameter 0.31 microm, geomertic standard deviation sigmag=2.19) at three doses (0.88, 3.0, 13.0 mg/kg body weight). The histopathological lung lesions were developed dose-dependentl...
