Rare Metals, EarlyView.ABSTRACT Transition metal‐based amorphous/crystalline (a/c) heterostructured catalysts have garnered significant attention due to their exceptional activity, stability, and cost‐effectiveness. However, the precise synergistic regulation of interfacial composition and phase states remains challenging.

Carbon‐Insertion‐Engineered WS2 Hierarchical Heterostructure Enabling Superior Sodium‐Ion Storage
Rare Metals, EarlyView.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.

野生动物学报, 2018 为了解麋鹿新鲜精液的品质和精子表面的结构特征,对12头处于繁殖季节的雄性麋鹿采用电刺激法获得新鲜精液,选用高活动率的精子12例制作标本,经扫描电镜对精子形态进行观察。结果发现,麋鹿精子属于典型的鞭毛精子,长约42 μm,头部呈梨形,长约6.4 μm,宽约4 μm,电镜下可见一定比例的畸形精子,通过对精子畸形的部位和原因进行分析,提出了精子样品制备时的注意事项。

Rare Metals, EarlyView.ABSTRACT The detection of volatile organic compounds (VOCs) holds significant implications in environmental monitoring and disease diagnosis. Traditional gas detection technologies are constrained by complex operation and high cost, thereby failing to satisfy real‐time detection demands.

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, EarlyView.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.
