Carbon‐Insertion‐Engineered WS2 Hierarchical Heterostructure Enabling Superior Sodium‐Ion Storage
Rare Metals, Volume 45, Issue 2, February 2026.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.

EFFECT of PCBs (AROCLOR 1254) on SPERMATOGENESIS in TESTIS of MOUSE [PDF]
, 2009 多氯联苯（PCBs）是一类由人工合成的氯代芳烃类化合物，被称作潜在的内分泌干扰物。由于他们具有类雌激素和抗雄激素的性质，对雄性生殖系统造成极大危害，导致不育和一些性激素依赖的生殖功能丧失。他们能够引起内源性系统改变，类似天然性激素，并抑制性激素实现其功能。 本文目的是研究多氯联苯对雄性小鼠生殖系统的睾丸生长与发育的影响。雄性小鼠随机分成五组，每组21只。采用不同浓度Aroclor1254（0，0.5，5，50，500µg/kg）对小鼠进行灌胃染毒，每星期三次。暴露50天后处死小鼠，称其体重 ...
