Advanced Materials, EarlyView.The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Influence of Y doping on high temperature oxidation resistance of titanium diboride coatings
Journal of Materials Research and TechnologyIn this study, DC magnetron sputtering was employed to deposit TiB2 coatings with varying yttrium content. The XPS results revealed that yttrium was identified in the TiB2 coating as yttrium oxide (Y2O3) due to the presence of residual oxygen.
