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 […]
