Influence of Obtainment Conditions and Excitation Into Spectral and Kinetic Characteristics of Cathodoluminescence in Y₂O₃:Eu Thin Films

Фізика і хімія твердого тіла, 2018
The spectra and kinetics of the rise and decay of the cathodoluminescence (CL) of thin films of Y2O3:Eu obtained by RF-magnetron sputtering was investigated. Based on the shape of the CL spectra at different excitation energies, showed the possibility of

High‐Throughput Screening of REBCO Superconducting Thin Films Fabricated Via Combinatorial Inkjet Printing and TLAG Process

Advanced Materials Technologies, EarlyView.
A methodological framework is presented for combinatorial REBCO thin films fabricated by drop‐on‐demand inkjet printing with controlled Rare Earth composition gradients. Automated, synchrotron‐based, and local characterization techniques produce comprehensive property maps that correlate composition and TLAG process parameters with superconducting ...

On the stability of the oxides film formed on a magnesium alloy containing rare-earth elements

Electrochimica Acta, 2018
The electrochemical behaviour of a commercial magnesium alloy containing rare-earth elements, the WE43, was investigated by electrochemical techniques in both sulphate and chloride solutions and compared to that of pure magnesium (99.95 wt %).

Mechanism of Solid Solution‐Driven Texture Induced by Ag Doping in YBCO Superconductor

Advanced Science, EarlyView.
Ag‐doped YBCO with a designed concentration gradient is produced by dual‐material co‐extrusion and freeze‐drying. During annealing, Ag+ ions diffuse into Y123, substituting for Cu(1) and inducing c‐axis relaxation. This leads to the formation of [001]‐oriented YBCAO, creating a coherent interface that templates the textured growth of Y123. Consequently,

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

Advanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...
