Rare Metals, EarlyView.ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser

辅助卵母细胞激活对经睾丸显微取精术获取活动精子患者卵胞浆单精子注射治疗结局的影响
Zhongshan Daxue xuebao. Yixue kexue ban, 2022 目的探讨辅助卵母细胞激活 （AOA） 对经睾丸显微取精术 （micro-TESE） 成功获得活动精子患者行卵母细胞胞质内单精子注射 （ICSI） 治疗的实验室和临床结局影响。方法回顾性分析2018年至2020年间经micro-TESE已获取活动精子的非梗阻性无精子症男性患者167人，配偶经常规超排卵获得成熟卵母细胞行ICSI治疗230个周期，比较分析ICSI后是否经钙霉素行AOA处理的实验室和临床结局差异。结果激活组 （G1） 和未激活组 （G2） 的女方平均年龄 （29.96 ± 4.61vs. 30.

Recent Progress in the Development of Metal‐Based Radiosensitizations for Cancer Therapy: A Review
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Radiotherapy (RT) remains an indispensable means in cancer treatment; however, its therapeutic efficacy is often limited by tumor radioresistance and side effect of damage to healthy tissue. The advances in nanotechnology have propelled metal radiosensitizers to forefront of precision medicine.

, 1950 自然界に於ては精子の参加をまたないで雌性要素のみで単独に発育を開始した実例は少くない。殊に家蚕の単為生殖に関する研究は古来、多くの人達に依って行われて来た。更に家蚕の処女卵に於て精子に代わる或る人為的刺戟を与えることにより単独に胚子を発達させ得る事は既に佐藤博士(1925、1934)並に川口博士(1934)等により実験的にも確立されて居り共の遺停学的並に細胞学的研究は精細を極めている。さて超短波領域の電磁波が一般生活体に対し顕著な影響を及す事実は単なる熱的二次作用だけで無く ...

The Rhetoric of Disenchantment: Ghost Belief and Secular Critique in Early Twentieth‐Century China
Cognitive Science, Volume 50, Issue 1, January 2026.Abstract This study presents the first large‐scale empirical analysis of how ghosts and spirits were debated during China's early twentieth‐century secular transformation. Using a novel dataset of over 2000 digitized texts—including newspapers, periodicals, and essays from 1890 to 1949—we combine close reading, AI‐assisted annotation, and statistical ...
