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

ABSTRACT The similar physicochemical properties of alkali metal elements make the co‐enrichment and precise separation of Cs+ and Rb+ in complex brine systems highly challenging. Here, an all‐inorganic strategy is proposed, which achieves efficient enrichment and precise separation of Cs+ and Rb+ in high‐salt systems by constructing Sr2+/Ba2+‐based ...

Achieving Transboundary Water Security Through Water Innovations: A Framework and Cases
ABSTRACT Alternative sources of freshwater, provided by various innovations, have long been available to countries facing acute water stress. We hypothesize that avoiding and/or resolving conflict with neighbors—caused by the uncertainty of continued access to shared surface water and groundwater sources—is another driver of innovation adoption ...

ABSTRACT Most research into the relationships of linguistic complexity and accuracy to functional adequacy has focused on either spoken or written mode. The current study extended previous studies by investigating these associations across both modalities and how the nature of these relationships was influenced by learners’ L2 proficiency and task type.

啤酒生产过程中会产生大量的废水,必须经过处理达到排放标准后排放或者达到回用标准后回用。根据啤酒废水来源不同其水质明显不同,这是废水回用的基础。对啤酒生产工艺及废水产生情况进行了介绍,综述了几种新型废水回用技术,主要包括膜过滤、膜生物反应器、低温等离子体以及电化学方法,总结了这些新技术各自的优缺点,并对其在废水回用中的应用情况作相关展望。
