Intriguing luminescence properties of (Ba, Sr)₃Si₆O₉N₄: Eu²⁺ phosphors via modifying synthesis method and cation substitution

Synthesizing pure phase Ba₃Si₆O₉N₄ by the conventional solid-state reaction method is challenging because of easily formed secondary phase Ba₃Si₆O₁₂N₂ showing similar crystal structure. In this work, an alternative low temperature synthesis method is...

Advancing data assimilation in operational hydrologic forecasting: Progresses, challenges, and emerging opportunities

Data assimilation (DA) holds considerable potential for improving hydrologic predictions as demonstrated in numerous research studies. However, advances in hydrologic DA research have not been adequately or timely implemented in operational forecast systems to improve the skill of forecasts for better informed real-world decision making. This is...
