Advances in Elemene Nanodelivery Systems: From Material Design to Disease Treatment
Rare Metals, EarlyView.ABSTRACT Elemene (ELE) is a bioactive sesquiterpenoid extracted from traditional Chinese herbs, demonstrating broad‐spectrum antitumor, anti‐inflammatory, and analgesic properties with significant therapeutic potential. However, its clinical utility is constrained by inherent physicochemical limitations, including volatility and hydrophobicity, which ...

, 2008 利用"河水衰减法"研究了不同培养条件下阴离子表面活性剂LAS在滇池典型入湖河口(海河口)缺氧水体中的生物降解及其动力学,探讨了温度、pH值、LAS的初始浓度、添加营养盐(NH4Cl或NaH2PO4)以及曝气等因素对LAS生物降解的影响.结果表明,在河口水体中的不同条件下,试验26 d后LAS的生物降解率都达95%以上,且降解服从二级动力学模型.温度、LAS的初始浓度、添加营养盐以及曝气均对LAS的降解有一定的影响.当水温从10℃增至25℃时,其降解速率p从0.21 d-1增至0.90

Rare Metals, EarlyView.ABSTRACT Single‐atom catalysis hinges on fundamental challenges in precisely controlling metal‐support interactions and rationally regulating metal–adsorbate relationships. Herein, we report a universal strategy for constructing highly efficient and well‐defined Cu(I) single‐atom catalysts based on a trifurcate AlL3 molecular support.

Rare Metals, EarlyView.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...
