We present optical and morphological characterizations performed on thermochromic V2O5 coatings. V2O5 coatings were obtained by oxidation of as-deposited VOx films. Comparisons were made among coatings oxidized at various temperatures. Photographic evidence is also shown to provide the reader a clear visual description of the color change that occurs during thermochromic process. Detailed study...

Single-crystalline V2O5 xH2O nanorings and microloops were chemically assembled via an ion-induced chemical spinning route in the designed hydrothermal system. The morphology and structure of products were investigated by means of scanning electron microscopy (SEM) and transmission electron microscopy (TEM). X-ray powder diffraction (XRD) measurement, energydispersive X-ray spectroscopy (EDS) m...

Vanadium pentoxide mesocrystals were synthesized from a mineral liquid crystalline precursor phase, a so-called tactosol. For comparative evaluation of solid formation from that phase, the distance between the vanadium pentoxide particles was lowered by three different modes: (a) by adding a 0.1 M NaCl solution, the electric double layer was compressed and controlled particle aggregation was in...

The present research investigated the sol–gel preparation, dielectric and ferroelectric properties of PZT films doped with 5 mol% vanadium oxide. Stable PZTV sols can be readily formed, and homogeneous, micrometer thick and pinhole-free PZTV films were obtained by using spin coating followed with rapid annealing. The X-ray diffraction patterns revealed that no parasitic or secondary phases were...

The use of quantum chemical approaches in the description of electronic properties of a catalyst and in understanding the mechanism of catalytic reactions is discussed. The electronic structure of vanadium pentoxide, V2O5, is studied based upon the cluster model with ab initio DFT and semiempirical INDO-type methods. Inter-atomic binding in vanadium pentoxide is determined to be of a mixed ioni...
