Li-ion battery systems, synthesized as epitaxial thin films, can provide powerful insights into their electrochemical processes. Crystallographic analysis shows that many important cathode oxides have an underlying similarity: their structures can be considered as different ordering schemes of Li and transition metal ions within a pseudo-cubic sublattice of oxygen anions arranged in a face-cent...

In this work, we report on the synthesis of nitrogen doped SrTiO3 nanoparticles with efficient visible light driven photocatalytic activity toward Cr(VI) by the solvothermal method. The samples are carefully characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, UV-Vis diffuse reflectance spectroscopy and photocatalytic test. It is found that nitroge...

The irradiation of SrTiO3 single crystals with swift heavy ions leads to modifications of the surface. The details of the morphology of these modifications depends strongly on the angle of incidence and can be characterized by atomic force microscopy. At glancing angles, discontinuous chains of nanosized hillocks appear on the surface. The latent track radius can be determined from the variatio...

Pulsed laser deposition (PLD) has been used to grow epitaxially oriented thin films of Cu and Pt on (100)-oriented substrates of both SrTiO3 and LaAlO3. The resulting films have been characterized for their crystalline orientations using x-ray diffraction (XRD) and for their surface morphologies using atomic force microscopy (AFM). The diffraction results illustrated that purely epitaxial Cu(10...

A CuO-loaded SrTiO3 catalyst showed highly photocatalytic activity for H2 evolution. This was prepared by an impregnation method and characterized XRD, TEM, BET, XPS, Uv-vis DRS PL techniques. Under optimum conditions, the best rate of evolution is 5811 µmol h?1g?1, whereas it a mere 34 h?1g?1 pure SrTiO3. High efficiency, low cost good stability are some merits that underline promising potenti...

The photochemical reduction of Ag and oxidation of Pb from aqueous solution by SrTiO3 leave insoluble reaction products (silver and PbO2, respectively) on the surface. Microscopic analysis has been used to relate the rates of these two reactions to the structure and orientation of SrTiO3 surfaces. The nonpolar (100) surface is the most reactive for silver reduction and the composition of the te...

A thermodynamic formalism is developed to calculate the pyroelectric coefficients of epitaxial ~001! Ba0.6Sr0.4TiO3 ~BST 60/40! and Pb0.5Zr0.5O3 ~PZT 50/50! thin films on ~001! LaAlO3 , 0.29 LaAlO3 :0.35(Sr2TaAlO6) ~LSAT!, MgO, Si, and SrTiO3 substrates as a function of film thickness by taking into account the formation of misfit dislocations at the growth temperature. The role of internal str...
