A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

Rare Metals, EarlyView.
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.

Was Einhard a widower?

Gender &History, EarlyView.
Abstract The ‘widow’ is a gendered, socially contingent category. Women who experienced spousal bereavement in the early middle ages faced various socio‐economic and legal ramifications; the ‘widow’ was further a rhetorical figure with a defined emotional register. The widower is, by contrast, an anachronistic category.
