Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Near‐infrared (NIR) phosphors with broadband and efficient emission are pivotal for the performance of NIR phosphor‐converted light emitting diodes (pc‐LEDs). In this study, the double perovskite phosphor La2MgTiO6:Cr3+ phosphor with broadband emission in the range of 650–950 nm was prepared.

野生动物学报, 2012 从2011年12月到2012年4月,应用全事件取样法和目标动物取样法对南昌动物园2只处于育龄期的华南虎进行了丰容前后的行为观察,对丰容前后行为发生的时间分配、行为比例进行了研究比较。结果显示:丰容前主要出现踱步行为（刻板行为）,休息行为和摄食行为（摄食行为的发生受人为控制）等行为,丰容后行为谱明显丰富,行为种类增多,玩耍行为,社会行为占据整个行为谱的时间比重加大,丰容前后行为存在显著的差异。研究结构表明可以通过丰容来改变华南虎的行为节律,从而减少其刻板行为,增加了社会行为 ...

Gaoya dianqi, 2021 针对电力谐波加窗分析中的频谱泄漏和栅栏效应,利用电力信号在频域中的频谱只集中出现在谐波频点处的特点,以窗谱在主瓣中央和谐波频点的平坦性作为约束条件研究可同时有效抑制频谱泄漏和栅栏效应的加窗函数。提出了进行电力谐波分析时组合余弦窗须满足的基本条件。导出了窗谱的各阶导数,利用导数等于0作为主瓣中央和谐波频点的平坦性表示建立了组合余弦窗的参数方程组。对窗宽为整数个额定周期的新型窗函数的频谱进行了数值模拟,结果表明,新型窗函数在抑制频谱泄漏和抵抗栅栏效应方面性能优异,无需借助谱线插值即可实现高精度电力谐波分析。

Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.
