CO2 and/or H2O were reduced to CO/H2 in micro-tubular solid oxide electrolysers with yttria-stabilized zirconia (YSZ) electrolyte, Ni-YSZ cermet cathode and strontium(II)-doped lanthanum manganite (LSM) oxygen-evolving anode. At 822 C, the kinetics of CO2 reduction were slower (ca. 0.49 A cm 2 at 1.8 V) than H2O reduction or co-reduction of CO2 and H2O, which were comparable (ca. 0.83 to 0.77 A...

Inkjet printing is a scalable technique that can fabricate customised three-dimensional microstructures, reproducibly, accurately, and with high material utilisation, by multiple layers sequentially onto previously printed layers, to produce architectures tailored in this case electrochemical reactors. Printable yttria-stabilised zirconia (YSZ) lanthanum strontium manganite (LSM) inks were form...

The discovery of superconductivity in Nd0.8Sr0.2NiO2 (ref. 1) introduced a new family layered nickelate superconductors that has now been extended to include range strontium doping2,3, praseodymium or lanthanum place neodymium4–7, and the five-layer compound Nd6Ni5O12 8). A number studies have indicated electron correlations are strong these materials9–15, feature often leads emergence magnetis...

Analysis of the existence memory phenomena in model heterostructures based on doped ferrite La0.5Sr0.5Fe0.75Al0.2Ni0.05O3-δ with a perovskite structure has been carried out. It was demonstrated that one 5-10 μm thick layer sandwiched between Pt and Ni electrodes exhibits an analog memristor behavior. Under positive polarity, this heterostructure shows smooth increase electrical conductivity, op...

Recently, high-temperature stability is a challenge in number of microwave absorption materials. Hence, researchers are still searching for novel material system preferably with resistance to be applied the field absorption. Here, current study, toward this aim, lanthanum (La)-doped strontium titanate (SrTiO3) blended TiO2 were fabricated by hot-press sintering vacuum. The as-prepared samples d...

The hole-doped manganite La0.7Ca0.3MnO3 and the electron-doped manganite La0.7Ce0.3MnO3 undergo an insulator to metal transition at around 250 K, above which both behave as a polaronic semiconductor. We have successfully fabricated an epitaxial trilayer (La0.7Ca0.3MnO3/SrTiO3/La0.7Ce0.3MnO3), where SrTiO3 is an insulator. At room temperature, i.e. in the semiconducting regime, it exhibits asymm...
