Rare Metals, EarlyView.ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐

Rare Metals, EarlyView.ABSTRACT Expanding near‐infrared (NIR) spectral response and utilizing ultraviolet (UV) photons are effective strategies for enhancing the power conversion efficiency (PCE) of lead halide perovskite solar cells (PSCs). However, the range of NIR spectral response extension and the utilization of UV light for devices are not enough, and the loss of ...

Effects of inhibitor targeting the EGFR/MEK signaling pathway on the growth and development of Echinococcus multilocularis and its molecular mechanism [PDF]
, 2016 泡状棘球蚴病(Alveolarechinococcosis，AE)是由泡状棘球绦虫(Echinococcusmulticularis，Em)幼虫引起的一种致命性的人畜共患寄生虫病。目前对于泡球蚴病的治疗方法十分有限，寻找新型药物靶点十分必要。EGF/EGFR信号通路调控细胞的多种生命活动包括增殖、分化、迁移等，本文在实验室前期研究的基础上，探讨了小分子抑制剂通过对泡球蚴EGF/EGFR介导信号通路作用，对泡球蚴生长发育的影响及其机制。 本文对EGFR抑制剂CI-1033 ...

Rare Metals, EarlyView.ABSTRACT Lung cancer remains the leading cause of cancer‐related deaths worldwide, yet immune checkpoint blockade (ICB) is often compromised by an immunosuppressive tumor microenvironment (TME) with acidosis, hypoxia, and poor T cell infiltration. Here, we develop a TME‐responsive nanoplatform (MgH2@Lip/PD‐L1) that couples hydrogen gas therapy with PD ...

Design, Synthesis and Transformation Evaluation of Phosphorous-containing Prodrugs [PDF]
, 2010 摘要 艾滋病是严重危害人类健康的全球性传染病。目前，医学界至今仍未成功研究出可以彻底治疗AIDS的方法。核苷逆转录酶抑制剂（NRTIs/NtRTIs）一直是主导的抗AIDS药物，研究发展迅速。但这类药物的临床应用都收到了一定的限制，例如d4T的骨髓毒性，低治疗指数，难通过血脑屏障以及在血浆中半衰期短等。磷酸酯类前药是近年核苷类药物结构修饰的一个重要方向。尽管在氢亚磷酸酯酯作为前药载体的应用方面有了一定的发展，但是其转化释放前药的机理问题目前很少有过系统的研究。因此 ...
