Encapsulation of Bi2S3 Within Multifunctional Sulfurized Polyacrylonitrile Matrix Enables High‐Performance Wide‐Temperature Sodium/Potassium‐Ion Batteries Through Solid–Solid Conversion

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT With high theoretical capacity and low cost, bismuth sulfide (Bi2S3) demonstrates considerable potential as an anode for sodium/potassium‐ion batteries (SIBs/PIBs). Unfortunately, significant volume variation, low electrical conductivity, and dissolution of polysulfides drastically weaken their intrinsic merits.

Insights Into High‐Temperature Mechanical Properties and Oxidation Behavior of Ta‐Optimized TiAl‐Based Alloys Additively Manufactured via Directed Energy Deposition

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Directed energy deposition (DED) is an effective method to process complex components with high efficiency, owing to its significant advantage of material saving and features of microarea metallurgy and rapid solidification. This study presents a nano‐Ta‐optimized Ti‐45Al‐8Nb (at%)‐based alloy synthesized via DED. The prepared TiAl‐based alloy

两种载体固定化白腐真菌的优化实验及性能比较

Gongye shui chuli, 2011
采用SA—CaCl2包埋法和PVA—H3BO3交联法固定化白腐真菌,并进行固定化组分优化,并对两种方法所形成的固定化小球性能进行了比较。结果显示:固定化组分优化后,两种方法均能得到较好的固定化效果。由性能比较结果可知:SA、PVA固定化小球均有较好的细胞增殖能力和良好的传质性,SA固定化小球机械强度较低,剧烈搅动易破裂,只适宜保存在潮湿环境中,而PVA固定化小球强度较高,原料价格较低,固定化小球在空气或水中均适宜保存。

Titanium Implant Abutments With Polydopamine‐Mesoporous Cerium Dioxide Coatings for Enhanced Antibacterial, Anti‐Inflammatory, and Soft Tissue Integration Properties

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.

Interfacial Reconstruction of Li+ Solvation Shell for Fast Diffusion Kinetics in Low‐Temperature Dendrite‐Free Li Metal Battery Enabled by Atomic Catalysts

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Low‐temperature lithium‐metal batteries (LT‐LMBs) are increasingly pursued for higher energy density and extended cycle life, yet suffer from severely depressed interfacial Li+ desolvation/diffusion kinetics due to the enlarged solvation structures as well as organic electrolyte solidification, ultimately inducing much higher barriers to ...
