Development of Tunable Materials From Well‐Defined Alendronic Acid Functionalized Polyacrylamide: An Opportunity for Actinide Decontamination

Journal of Polymer Science, EarlyView.
Alendronate‐based copolymers for Nd and Ce recovery. ABSTRACT Bisphosphonic acid groups are emerging as promising functionalities for actinide decontamination, due to their high density of chelating sites. However, the chemistry of bisphosphonate (in particular alendronate) materials remains complex and underexplored.

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.
