Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Zirconium dioxide (ZrO2) thin films are critical materials owing to their thermal stability, mechanical durability, and optical transparency enabling applications in photonic, sensing, and electronic devices. However, achieving uniform deposition via plasma‐enhanced chemical vapor deposition (PE‐CVD) has remained challenging due to poor ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Prelithiation is effective for compensating active lithium‐ion (Li+) loss in silicon (Si)‐based battery electrode materials. However, owing to the dynamic growth of the solid electrolyte interface (SEI), capacity fading remains the biggest challenge for the industrialization of Si electrodes.

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。

Zhongguo shiyan zhenduanxue, 2015 精液是由5%的精子和95%精浆构成的复合液,主要为睾丸、附睾、精囊、前列腺、尿道球腺分泌的液体。精子由睾丸产生,是生殖细胞经一系列有丝分裂形成的,在附睾中未成熟的精子最终形成有动力的精子,整个过程需要70天。精浆的化学成分十分复杂,包含各种蛋白、酶类、激素、微量金属元素等,是运送精子的载体,并为精子提供存活所需的能量和营养物质[1,2]。精液中有形成分除精子外,尚含少量白细胞（
