Topical and transdermal botanical formulations of the Chinese pharmacopoeia—A review
Phytotherapy Research, Volume 38, Issue 9, Page 4716-4735, September 2024.Abstract In pharmaceutics, ingredients are classified as active ingredients and excipients. In topical/transdermal phytomedicines, an ingredient may serve both functions. Published information on these dual‐purpose ingredients and their pharmacological relevance is limited.

Experimentally testing animal responses to prescribed fire size and severity
Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Deserts are often highly biodiverse and provide important habitats for many threatened species. Fire is a dominant disturbance in deserts, and prescribed burning is increasingly being used by conservation managers and Indigenous peoples to mitigate the damaging effects of climate change, invasive plants, and land‐use change. The size, severity,

Gongye shui chuli, 2021 以聚丙烯（PP）溶液涂覆不锈钢网进行表面疏水改性，优选涂覆液PP质量浓度为40 g/L，钢网目数为350目，改性后钢网表面水接触角153°。研究了改性钢网对3种模拟化学驱油田污水的破乳除油效果，结果表明，改性钢网对3种污水（表活剂驱污水、聚驱污水和二元驱污水）均具有聚结破乳效果，其中，对表活剂驱污水的破乳除油效果最好，最佳搅拌条件下除油率为85.4%；油珠粒径显著增大，基本从乳化油转化为分散油。

Gongye shui chuli, 2016 针对船舶含油污水成分复杂、乳化较严重、处理难度大的问题,采用破乳-絮凝协同处理的方法对其进行处理。通过单因素实验筛选出高效破乳剂和絮凝剂,并优化了破乳与絮凝处理的工艺条件。结果表明,在pH为8,温度为40 ℃,6#破乳剂投加量为200 mg/L,破乳时间为30 min;三氯化铁投加量为150 mg/L,搅拌强度为250 r/min,搅拌时间为120 s的条件下,除油率可达90%以上,处理后实际船舶含油污水的含油质量浓度可达7.1 mg/L,低于《船舶污染物排放标准》(GB 3552-1983)的排放限值。
