Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Lung cancer is one of the most common and deadly malignancies worldwide. Although immune checkpoint inhibitors, including PD‐1/PD‐L1 blockers, have benefited a subset of patients, response rates remain limited, and recurrence is frequent because of the immunosuppressive tumor microenvironment (TME), characterized by hypoxia and dysregulated ...

, 2008 利用河水衰减法研究阴离子表面活性剂(LAS)和非离子表面活性剂(NIS)在滇池水体中不同条件下的生物降解规律.结果表明:在滇池自然水体中,LAS和NIS均能生物降解,在试验时间(30d)内,L,AS的降解率达95%以上,NIS的降解率达92%以上,其降解动力学遵从二级动力模型.改变水温、表面活性剂初始浓度、pH值以及添加营养物质(葡萄糖或磷酸氢二钠)均对LAS和NIS的降解有一定的影响.水温对表面活性剂生物降解影响最大,当水温从20℃增至30℃时,LAS的降解速率从0.73-1增至2.10d-1 ...

Gongye shui chuli, 2011 考察了pH、温度、反应时间、浓度、光照、腐殖酸、干扰离子等因素对高铁酸钾降解双酚A的影响,并探讨了高铁酸钾降解双酚A的动力学机理以及对二沉池出水中双酚A的降解作用。研究表明:在pH=9.0,室温条件下,反应10 min后双酚A的降解率达最大值;光照对双酚A降解基本没有影响;腐殖酸对双酚A的降解有一定促进作用;干扰离子对双酚A降解影响较为复杂,既有促进作用又有抑制作用。以二沉池出水为基体,当m(高铁酸钾)∶m(双酚A)=5∶1,双酚A初始质量浓度为5.0 mg/L时,反应4 min后,双酚A的降解率达99%

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Titanium (Ti)–steel composite joints are prone to the formation of compounds such as TiC, TiFe, and TiFe2 during solid‐phase bonding. This phenomenon leads to premature failure and significantly reduces the bonding quality of the joints. However, the fracture behavior of the joint influenced by these compounds, particularly on the initiation ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT LiBH4 has drawn significant attention due to its high theoretical hydrogen storage capacity of 18.5 wt%, yet its practical application is hindered by the harsh dehydrogenation conditions. This paper proposes a strategy integrating ensemble learning with density functional theory (EL–DFT) for rapidly screening modified LiBH4 systems that ...

Gongye shui chuli, 2019 以石墨碳毡为阳极，采用氧气-阳极协同氧化法对亚甲基蓝（MB）、结晶紫（CV）和罗丹明B（RhB）进行降解，研究了不同电压下染料的降解动力学和降解途径。结果表明，染料在降解初期符合一级动力学特征，且其降解速率随电压的升高而加快。1.8、2.0 V电压下，MB和CV在12 h内脱色率达到100%，而RhB在3 h内脱色完全。染料在体系中主要通过N-去甲基化/去乙基化和发色团解离途径被部分降解。
