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.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Layered double hydroxides (LDHs) are attractive non‐noble catalysts for overall water splitting (OWS), yet their hydrogen evolution reaction (HER) activity is often limited by suboptimal *H adsorption and a paucity of accessible sites. Herein, we introduce an oxygen‐vacancy (Ov) engineering strategy to construct ultrathin Ni‐Fe LDH nanosheets ...

, 1996 探讨磁共振功能成像的方法，本文应用血氧合水平磁共振成像法，通过单次激发回波平面成像技术检测脑功能活动时的功能区信号变化。对８例右利手健康男性进行右手指随意运动的磁共振功能成像实验。实验采用静止－运动－静止三个阶段，运动又有简单复杂之分。此外，亦将梯度回波与平面回波技术同时应用在磁共振功能成像中以便进行比较。结果表明功能图像上可见左侧初级运动皮层区的信号变化，而在本实验中梯度回波图像上结果为阴性。平面回波成像技术在平面回波磁共振功能成像中磁敏感性高，稳定性好，有良好的时间分辨率 ...
