Kinetic‐Controlled Growth of Iron Chalcogenide Nanosheets Featuring Besnus Transition
ABSTRACT Two‐dimensional (2D) Fe‐based nanosheets have sparked wide attention owing to exotic magnetism, superconductivity and topological phases. However, the synthesis of 2D FemXn (X = Te/Se/S, m, n: integer), typically in a non‐stoichiometric ratio, remains challenging because of narrow thermodynamic windows.

ABSTRACT LiBH4 has drawn significant attention due to its high theoretical hydrogen storage capacity of 18.5 wt%, yet its practical application is hindered by the harsh dehydrogenation conditions. This paper proposes a strategy integrating ensemble learning with density functional theory (EL–DFT) for rapidly screening modified LiBH4 systems that ...

染色体22q12上THOC5和ADRBK2基因在人脑胶质瘤组织中mRNA表达
目的观察位于染色体22q12上的THOC5和ADRBK2基因在人脑胶质瘤肿瘤组织中mRNA表达。方法应用逆转录-聚合酶链反应(RT-PCR)及图像分析方法,检测17例人脑胶质瘤肿瘤组织和8例正常人脑组织中THOC5和ADRBK2基因mRNA表达。基因表达水平用THOC5或ADRBK2基因/β-肌动蛋白(β-actin)灰度比值×100表示。结果ADRBK2基因在正常人脑组织和人脑胶质瘤肿瘤组织中,均存在弱表达,统计分析显示无显著性差异(P>0.05);THOC5基因在正常人脑组织中弱表达 ...

ABSTRACT Catalytic NH3 decomposition has garnered substantial attention for hydrogen transformation and storage. Ni‐based catalysts continue to suffer from limited thermal stability and suboptimal low‐temperature activity, largely attributed to an incomplete understanding of the structure‐activity relationships and reaction mechanisms governing their ...
