The high Nb-containing TiAl-based alloy ingot beyond laboratory scale with a composition of Ti-46Al-8Nb (at.%) was prepared by vacuum induction melting process based on BaZrO3 refractory crucible. A round bar diameter 85 mm and length 430 finally obtained, the chemical composition, solidification pathway, microstructure tensile properties were investigated. results show that deviations Al Nb co...
Proton diffusion pathways and rates in Y-doped BaZrO3 solid oxide electrolyte from quantum mechanics
Proton conducting oxide electrolytes find potential application in proton ceramic fuel cells and electrolyzers operating at intermediate temperatures, e.g. 400–600 °C. However, state-of-the-art ceramics based on Y-doped BaZrO3 (BZY) have lower thermal expansion coefficient (TEC) than most commonly applied or conceived supporting electrode structures, making the assembly vulnerable to degradatio...
Understanding the behaviors of materials in their operating and manufacturing environments is essential not only scientific field, but also context designing industrial for target applications. In this study, we developed a high-temperature x-ray diffraction (XRD) system, using small microscope heating stage at BL02B2 beamline SPring-8. Newly designed sample cells composed sapphire single cryst...
We demonstrate that solid-state NMR spectra of challenging nuclei with a low gyromagnetic ratio such as yttrium-89 can be acquired quickly with indirect dynamic nuclear polarization (DNP) methods. Proton to (89)Y cross polarization (CP) magic angle spinning (MAS) spectra of Y(3+) in a frozen aqueous solution were acquired in minutes using the AMUPol biradical as a polarizing agent. Subsequently...
