Steam electrolysis using SrZr0.9Y0.1O3-α (SZY-91) electrolyte was investigated. Different electrode materials, i.e., porous platinum, Sr0.5Sm0.5CoO3 (SSC-55) for the anode and nickel for the cathode were examined in order to achieve better energy performance. The electrodes had poor electrode a...

Strontium zirconate oxide was synthesized by co-precipitation and the citrate route and was evaluated as a heterogeneous catalyst for biodiesel production. The catalyst samples were characterized by XRD, FTIR, and TG, and catalytic activity was measured based on the ester content of the biodiese...

Studies on the band gap engineering for photocatalysis and photovoltaic applications in SrZrO3 (SZO) being not explored. Here, we demonstrated a modified solid state reaction technique to prepare nanocrystalline perovskite with formula SrZr0.9Fe0.1O2.955 (SZFO). Phase analysis by X-ray powder di...

Excitation and emission spectra and decay kinetics of non-stoichiometric strontium zirconate powder phosphor were measured in the 8–500 K temperature interval. Phenomenological model was applied to extract quantitative parameters of the excited state levels and nonradiative quenching pathways r...

A lanthanum strontium zirconate pyrochlore material was substituted with Ni, and the effect of calcination temperature on important catalytic properties was evaluated. The introduction of the Ni into the pyrochlore decreased the BET surface as compared to non-Ni containing materials due to enhan...

Here we report on strontium zirconate as a getter for silicon dioxide and aluminum oxide in yttria stabilized zirconia (YSZ) single crystals for cleaning purposes. YSZ single crystals were covered with strontium zirconate powder and heat treated at 1450 °C in water vapor. After treatment the YS...

Aliovalent cation-doped perovskite-type oxides (ABO3) exhibit proton conductivity originating from the hydration of oxide ion vacancies, which is accompanied by structural deformation, i.e. chemical expansion. The chemical expansion may lead to failure in electrochemical devices, and thus it is ...

Increase in the efficiency of a gas turbine system is possible by operating it at increased temperature of hot working gases. However, it puts a direct thermal load on the material of the blade, which in turn demands for increased cooling capacities for the blade. Present paper deals with simula...

Strontium zirconate has been deposited on stainless steel substrates by atmospheric plasma spray technique. In-flight temperature and velocity of strontium zirconate particles were measured by the ‘spraywatch’ particle diagnostics system. The coatings have been characterized by x-ray powder di...

Electrochemical reduction of water to hydrogen holds great promise for clean energy, while its widespread application relies on the development of efficient catalysts with large surface area, abundant exposed active sites and superior electron conductivity. Herein, we report a facile strategy to...

Nanosized colloidal rhodium oxide particles in water were obtained by using a nanosecond pulsed excitation, starting from a high purity rhodium target. The as-synthesized colloids show an almost spherical shape and size in the range between 2 and 12 nm. Characterization results indicate that col...

Rhodium (Rh) oxide thin films were prepared by reactive sputtering at different substrate temperatures under an oxygen or water (H2O) vapor atmosphere, and their crystal structure, density, optical properties, and electrochromic properties were investigated. The film density decreased with decre...

A rhodium modification of aluminide coating on Mar-M247 superalloy was performed by electrodepositing of 0.5 μm thick rhodium layer followed by chemical vapour aluminizing. It was found that rhodium dissolves in the aluminide coating. Oxidation resistance of undoped coating is worse than the rh...

We have explored the homogeneity range of Cu12-xSnxSb4S13 tetrahedrites, the peculiarities of their crystal structure, and the oxidation state of tin in them. Phase analysis and crystal structure refinement based on high-resolution powder X-ray diffraction have shown that tin-bearing tetrahedrit...

Spontaneous tin whisker growth has been mysterious and catastrophic for more than half century. The difficulty in the research on this topic consists of the randomness of the whisker growth, the slow growth rate and many other tricky factors. Herein, with Ti2SnC-Sn as a new platform, fast tin wh...

SnO2 has been considered as one of the promising anode materials for Lithium-ion batteries (LIBs) owing to its high theoretical specific capacity and low operating potential.
