ABSTRACT The polyanionic compound Na3V2(PO4)3 (NVP) has emerged as a competitive cathode material for sodium‐ion batteries (SIBs), owing to its high‐voltage redox activity (3.4 V vs. the Na+/Na reference couple) and NASICON‐type framework that enables superior ionic conductivity.

摘要: (免费在线浏览)体外循环冠状动脉搭桥术(CABG)是长期以来心脏外科进行心肌再血管化的标准手术,但体外循环可能会带来一些相关的问题,如术后认识功能障碍、脑卒中、凝血功能障碍、全身炎性反应及由此引发的多个器官系统功能障碍等。因此,近年来非体外循环下冠状动脉搭桥术(OPCAB)引起人们的注意,以期减少与体外循环有关的术后合并症。OPCAB同CABG相比,能明显降低术后左心室功能不全的发生率,减少住院时间、输血量,降低医疗费用,降低术后心房颤动及脑卒中的发生率 ...

Carbon‐Insertion‐Engineered WS2 Hierarchical Heterostructure Enabling Superior Sodium‐Ion Storage
ABSTRACT Tungsten disulfide (WS2) is considered a promising anode material for sodium‐ion batteries (SIBs). However, its practical application is hindered by poor electrical conductivity, large volume changes during cycling, and sluggish ion diffusion kinetics, which lead to unsatisfactory electrochemical performance.

体外循环心脏直视手术应用冷停跳液灌注冠状动脉保护心肌(附50例心肌温度监测结果) [PDF]
体外循环心脏直视手术阻断主动脉血流期间,心肌处于缺血状态,若无有效的保护措施,随着缺血时间的延长,心肌能量的耗竭,无氧代谢产物的堆积及酸中毒等可造成心肌不同程度的损害。临床上常见的术后低排综合征等严重并发症与术中心肌保护不当有密切关系。而低排综合征又是术后常见的死亡原因之一,死亡率达90%。因此 ...
