We report on the laser damage resistance of ion beam-sputtered oxide materials (Al2O3, Nb2O5, HfO2, SiO2, Ta2O5, ZrO2) and mixtures of Al2O3-SiO2, Nb2O5-SiO2, HfO2-SiO2, Ta2O5-SiO2, and ZrO2-SiO2, irradiated by single 500 fs pulses at 1030 nm. Laser-induced damage threshold (LIDT), refractive index, and bandgaps of the single-layer coatings are measured. For pure oxide materials a linear evolut...

In situ band gap mapping of the V2O5(001) crystal surface revealed a reversible metal-to-insulator transition at 350-400 K, which occurs inhomogeneously across the surface and expands preferentially in the direction of the vanadyl (V=O) double rows. Supported by density functional theory and Monte Carlo simulations, the results are rationalized on the basis of the anisotropic growth of vanadyl-...

Investigated effects of varying C-rates on stress and structure changes in V2O5. A linear increase in the stress as a function of x in LixV2O5 is observed. C-rate does not directly contribute to larger intercalation stress. A rapid increase in disorder within LixV2O5 is correlated with higher Crate. a r t i c l e i n f o

A one-step, room-temperature method is described to chemically synthesize bulk quantities of microns long, 100-180 nm diameter nanofibers of electrically conducting poly(3,4-ethylenedioxythiophene)(PEDOT) in the form of powders, or as optically transparent, substrate-supported films using a V2O5 seeding approach.

Sodium superoxide loaded phosphovanadate based glass systems were prepared from a mixture of vanadium pentoxide (V2O5), phosphorus (P2O5) boric acid (H3BO3) and sodium (NaO2) using melt-quenching method. Amorphous phase as-prepared system confirmed XRD technique. Surface morphology studied scanning electron microscope. Ultraviolet-visible spectroscopy was employed to extract complex optical par...
