Dipole‐Engineered Conductive Additives for Ultrastable Interphase Evolution in High‐Areal‐Capacity Silicon Anodes

open access: yesAdvanced Functional Materials, EarlyView.
In the work reported herein, dipole‐engineered sulfonated carbon nanofibers enable conductive additives to actively regulate interphase formation in silicon anodes. Polar sulfonyl groups guide electrolyte decomposition to form a compact LiF‐rich interphase while promoting robust integration with silicon.

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers

open access: yesAdvanced Functional Materials, EarlyView.
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...

Interplay Between Phase Evolution, Fe Migration, and Oxygen Redox in O3‐Type NaxFeyMn1−yO2 Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
Why do Na‐ion battery cathodes, that are compositionally closely related, follow different structural paths during battery operation? This work shows how Fe content controls when iron atoms migrate from their original sites. Early migration locks the layers and blocks key phase transitions, whereas delayed migration permits fuller structural ...

Graded‐Interface Dual‐Environment Hydrogel‐Polymer Electrolyte for Stabilized Anode and Sustained Cathode Kinetics in Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A graded‐interface hydrogel‐polymer electrolyte decouples water activity to simultaneously stabilize the Zn anode and sustain cathode kinetics. The flexible design supports dendrite‐free cycling over 1600 h, high capacity in both MnO2 and V2O5 full cells, and stable pouch‐cell performance under bending, resolving the fundamental water conflict in ...

非细菌性血栓性心内膜炎与卒中 Nonbacterial Thromboendocarditis and Stroke

open access: yesZhongguo cuzhong zazhi, 2019
【摘要】 非细菌性血栓性心内膜炎(nonbacterial thromboendocarditis,NBTE)是一种异质性疾病,以心脏瓣膜赘生物形成为特征。NBTE与恶性肿瘤及其他原因所致的高凝状态有关,是引起隐匿性卒中的原因之一。经食道超声心动图和头颅MRI是诊断NBTE相关卒中的重要方法。合并恶性肿瘤的NBTE患者发生卒中的风险较正常人群高,短期内卒中的复发率高、预后差。因此,早期识别NBTE相关性卒中,并开展相应的治疗和二级预防是值得临床关注的问题 ...
