Exceptionally High‐Performance Reversible Solid Oxide Electrochemical Cells with Ultrathin and Defect‐Free Sm _0.075 Nd _0.075 Ce _0.85 O _2‐δ Interlayers (Adv. Funct. Mater. 49/2022)

MgCuAl2-type Intermetallics REPdCd2(RE = Ce, Pr, Nd, Sm)

The cadmium-rich intermetallic compounds REPdCd2 (RE = Ce, Pr, Nd, Sm) were obtained by high-frequency melting of the elements in sealed niobium ampoules and subsequent annealing in muffle furnaces. The REPdCd2 phases crystallize with the orthorhombic MgCuAl2-type structure, space group Cmcm. The structure of NdPdCd2 was refined from single-crystal X-ray diffractometer data: a = 421.9(3), b = 9...

Disorder-Induced Transition to Entangled Vortex Solid in Nd-Ce-Cu-O Crystal

Local magnetic measurements in a highly anisotropic Nd-Ce-Cu-O crystal reveal a sharp onset of an anomalous magnetization peak at a temperature-dependent field Bon. The same field marks a change in the field profiles across the sample, from profiles dominated by geometrical barriers below Bon to Bean-like profiles above it. The temperature dependence of Bon and the flux distribution above and b...

Sm-Nd systematics of Earth are inconsistent with a superchondritic Sm/Nd ratio

The relationship between the compositions of the Earth and chondritic meteorites is at the center of many important debates. A basic assumption in most models for the Earth’s composition is that the refractory elements are present in chondritic proportions relative to each other. This assumption is now challenged by recent Nd/Nd ratio studies suggesting that the bulk silicate Earth (BSE) might ...

Performance of Reversible Solid Oxide Cells: A review

It was shown about 25 years ago that solid oxide fuel cells (SOFC) could also work in the solid oxide electrolyser cell (SOEC) mode. Electrolysis of both water (steam) and CO2 was demonstrated. During the 1990'ies very little electrolysis work was reported in the open literature, whereas an enormous amount of results on the SOFC R&D appeared. Recently, the increasing interest in hydrogen produc...
