To obtain superconductivity in a layered copper-oxide compound, it is necessary to introduce charge carriers into the antiferromagnetic CuO2 planes. Recent neutron diffraction studies of the system La1.6−xNd0.4SrxCuO4 [1,2] provide evidence that the dopant-induced holes choose to segregate into periodically-spaced stripes which separate antiferromagnetic domains, in a manner similar to that fou...

Abstract In this work, La 2 NiO 4+ δ - x Ce 0.55 0.45 O 2− (denoted as LNO- LDC) with various LDC contents ( = 0, 10, 20, 30, and 40 wt%) were prepared evaluated bifunctional oxygen electrodes for reversible solid oxide cells (RSOCs). Compared the pure LNO, optimum composition of LNO-30LDC exhibited lowest polarization resistance R p ) 0.53 0.12 Ω·cm in air at 650 750 °C, respectively. The enha...

A low-cost manufacturing procedure has been developed for the fabrication of planar anode-supported solid oxide fuel cell including only two thermal treatments. This method is also environmental-friendly since slurries are water based and use non-toxic additives. Slurries were formulated by optimizing powder quantity, minimizing organic compounds while controlling their stabilities rheological ...
