Physical Model for Quantitative Organization Design on Mechanical Performance of Nanotwin Unit in Face‐Centered Cubic Metal

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Arranging functional units into a specific organization is a practical structural strategy for achieving fabulous performance, known as the functional unit and organization (FUO) paradigm. This paradigm offers a concise shortcut to establishing structure–performance relationships.

具有场板结构的AlGaN/GaN HEMT的直流特性

open access: yes, 2008
研制成功具有场板结构的AlGaN/GaN HEMT器件,对源场板、栅场板器件的性能进行了分析.场板的引入减小了器件漏电和肖特基漏电,提高了肖特基反向击穿电压.源漏间距4μm的HEMT的击穿电压由常规器件的65V提高到100V以上,肖特基反向漏电由37μA减小到5.7μA,减小了一个量级.肖特基击穿电压由常规结构的78V提高到100V以上.另外 ...

Bio‐Inspired Damage‐Tolerant Si‐Based Anode for Lithium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Silicon is a promising anode material for lithium‐ion batteries due to its high specific capacity, but it suffers from large volume change and rapid brittle fracture during the lithiation/delithiation cycling process. Although the majority of the literature work has tried to avoid fracture by restraining volume expansion or relieving expansion

Recent Progress in Predicting Corrosion Evolution and Degradation of Aluminum Alloys by Multiscale Simulation Frameworks

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT As the second most widely used metallic material after steel, research on the corrosion resistance of aluminum (Al) alloys holds great significance. To overcome the inherent limitations of experimental methods in capturing long‐term multifactor corrosion behavior of Al alloys, this review summarizes recent advancements in the multiscale ...

成年人某些个性特征的年龄差异研究

open access: yes, 1996
采用NEO—FFI简式对593名20至94岁成年人进行了个性特征的年龄差异研究。被试分为青年(20~39岁)、中年(40~59岁)、老年(60~74岁)和老老年(75岁及以上)4组,文化程度均初中以上。结果表明:问卷表再测信度合格,自评与亲友评定间有显著相关;除开放性特征(O)随增龄下降,即青年组较年长三组更加开放外,神经质(N)、内外向(E)、和谐性(A)和认真负责(C)量表分均无明显年龄差异;两性个性特点比较,女性N分及A分均明显高于男性;除年龄和性别因素外,健康善对N、E、C分,文化程度对N和O分,

Integrated Implantation of an Ultrasound‐Actuated BiFeO3 Piezoelectric Film and Bone Marrow Mesenchymal Stem Cell Sheet for Spatially and Stage‐Programmed Osteoarthritis Repair

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Osteoarthritis (OA) therapy remains constrained by the coexistence of irreversible cartilage loss and a persistently hostile joint microenvironment characterized by oxidative stress, synovial inflammation, and impaired tissue‐regenerative signaling.
