Improved electrical properties of Nb doped BaCe0.9Y0.1O2.95 electrolyte for intermediate temperature SOFCs obtained by autocombustion method
(Elsevier Science Sa, Lausanne, 2014)
Nb doped BaCe0.9Y0.1O2.95 (BCY) powders were synthesized by both solid state reaction (SSR) and autocombustion reaction (ACR) method to investigate how different synthesis routes influence the properties of the powders and ...
Mechanochemical synthesis of yttrium manganite
(Elsevier Science Sa, Lausanne, 2013)
Yttrium manganite (YMnO3) is a multiferroic material, which means that it exhibits both ferromagnetic and ferroelectric properties, so making it interesting for a variety of technological applications. In this work, ...
Comparative study of structural and electrical properties of Pr and Ce doped BiFeO3 ceramics synthesized by auto-combustion method
(Elsevier Science Sa, Lausanne, 2016)
Polycrystalline Bi1-xPr(Ce)(x)FeO3 ceramics (x = 0, 0.03, 0.05 and 0.10) were prepared by auto-combustion method using urea as a fuel. The influence of Pr(Ce) doping on structural, vibrational, morphological, dielectric ...
Far infrared study of impurity local modes in palladium-doped PbTe and PbSnTe
(Elsevier Science Sa, Lausanne, 2009)
PbTe and Pb0.85Sn0.15Te single crystals. doped with Pd, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and 300 K. The experimental spectra were numerically ...
Far infrared reflectivity spectra of lead-telluride doped with Ytterbium
(Elsevier Science Sa, Lausanne, 2008)
Single crystal samples of lead-telluride doped with Ytterbium were made using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 to 300 K were measured. Analysis of the experimental ...
Controllable morphology, dielectric, magnetic and reflection loss characteristics of ferrite/wax composites for low-loss applications
(Elsevier Science Sa, Lausanne, 2021)
In this work, composites of M-type Ba(1-x)SrxFe12O19 hexagonal ferrite (x=0.0, 0.2, 0.4, 0.6, 0.8 and 1.0) and paraffin wax have been prepared. Microwave characterization of the prepared composites was performed with a ...
Flexible lead-free NBT-BT/PVDF composite films by hot pressing for low-energy harvesting and storage
(Elsevier Science Sa, Lausanne, 2021)
The idea of this work is finding the way to efficiently and safely use mechanical energy released in small quantities around us to power up small-scale electronic devices used in everyday life. To this purpose, flexible ...
