Influence of the indium concentration on microstructural and electrical properties of proton conducting NiO-BaCe0.9-xInxY0.1O3-delta cermet anodes for IT-SOFC application Abstract: Optimization of the major properties of anodes based on proton conductors, such as microstructure, conductivity and […]
Polaronic ferromagnetic behavior in ClO4- doped poly(3-hexylthiophene) at room temperature Abstract: The magnetic properties of pressed pellets of ClO4− partially doped poly(3-hexylthiophene) have been investigated in the range from 5 to 300 K and a ferromagnetic phase was observed […]
Optical phonon characteristics of an orthorhombic-transformed polymorph of CaTa2O6 single crystal fibre Abstract: Infrared-reflectivity spectroscopy and micro-Raman scattering were used to determine the optical phonon features of orthorhombic calcium tantalite (CaTa2O6) single crystal fibres. The fibres, […]
Mechanosynthesis of the multiferroic cubic spinel Co2MnO4: Influence of the calcination temperature Abstract: Multiferroic materials showing magnetoelectric coupling are required in various technological applications. Many synthetical approaches can be used to improve the magnetic and/or electrical […]

Structural refinement, optical and electrical properties of Ba1-x Sm-2x/3 (Zr0.05Ti0.95)O-3 ceramics Abstract: Samarium doped barium zirconate titanate ceramics with general formula [Ba1−x Sm2x/3](Zr0.05Ti0.95)O3 [x = 0, 0.01, 0.02, and 0.03] were prepared by high energy ball […]
Metal to insulator transition in Sb doped SnO2 monocrystalline nanowires thin films Abstract: We report on the growth and transport properties of single crystalline Sb doped SnO2 wires grown from chemical vapour deposition. While undoped samples […]
Photoluminescence emission at room temperature in zinc oxide nano-columns Abstract: Hydrothermal microwave method (HTMW) was used to synthesize crystalline zinc oxide (ZnO) nano-columns at the temperature of 120 °C with a soaking time of 8 min. […]
The influence of self-ordered TiO2 nanotubes microstructure towards Li+ intercalation Abstract: In this work, TiO2 nanotubes were prepared by anodization at a constant voltage in an electrolyte composed of fluoride species provided by ionic liquid (1 or 5 vol.%), applying 40 or 80 V. Different tube diameters […]
