ABSTRACT This study successfully prepared a high‐palladium (Pd)‐loading (51 wt%) Pd/Al2O3 composite through multiple wet impregnation. The material exhibited excellent hydrogen isotope separation performance, with metal–support interactions endowing it with a higher plateau pressure and lower desorption temperature.

ABSTRACT High‐entropy alloys (HEAs) have attracted considerable interest from researchers owing to their tunable chemical compositions, exceptional structural stability, and promising catalytic properties. However, their large‐scale application is often hindered by complex manufacturing techniques and poor durability.

摘要: (免费在线浏览)体外循环是将回心的静脉血从上、下腔静脉或右心房引出体外,在人工心肺机进行氧合和排出二氧化碳后,再由血泵输回体内动脉的一种血液循环方法。体外循环下心内直视手术是治疗先天性心脏病、风湿性心脏病和冠心病的主要方法之一。体外循环下心内直视手术的特点是专业性强、手术步骤复杂、病人危险性大,因此护理人员手术前的准备和手术中与手术医生之间的配合对于手术成功起到至关重要的作用。本院在2007年1月―2007年12月对184例心脏病人施行了体外循环下心内直视手术,效果满意 ...

ABSTRACT The development of sodium‐ion batteries (SIBs) is limited by slow charge transfer kinetics and large material volume changes caused by the large radius of Na+. Leveraging the excellent physicochemical properties and unique heterostructures of metal selenides, ultrafine hetero‐CuFeSe2‐CoSe2 nanoparticles are in situ wrapped by ...

ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...
