Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Recovering palladium (Pd) from low‐concentration metallurgical wastewater still poses significant challenges. In this study, triaminoguanidine hydrochloride was used as the key functional site, and three guanidine‐functionalized covalent organic frameworks (GCOFs) were successfully constructed by adjusting the substituents (–H, –OH, and –OCH3)

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Chlorination roasting has emerged as a promising pyrometallurgical strategy for the selective recovery of lithium from spent lithium‐ion batteries (LIBs). In this study, a natural roasting agent, seawater‐derived chlorides, was employed to selectively extract lithium from spent LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode. MgCl2·6H2O, a main component

Zhongguo shiyan zhenduanxue, 2015 骨科行重大手术治疗时可能会导致出血量较大,需要进行输血治疗。异体输血是输血的重要来源,为临床治疗提供了重大帮助[1]。但是异体输血存在较大问题,可能会导致传染性疾病的发生,也会出现一些不良反应,加上血源比较短缺,异体输血越来越存在局限性。回收式自体输血是将患者自体血液进行回收处理,然后再在患者需要的时候回输回患者体内,起到治疗疾病的作用[2]。回收式自体输血对患者的免疫功能影响较小,不良反应较小[3]。

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...
