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.

Probing a Reactive Alkyne Center Aligned via a Triphenylmethane Tripod on Au(111) for Electric Field‐Induced Chemistry by STM and TERS

Small, EarlyView.
Electric‐field‐induced chemistry at solid/vacuum interfaces offers precise control over chemical reactions. In this study, a triphenylmethane‐based tripod with a terminal alkyne is anchored upright on a gold surface. Advanced scanning tunneling microscopy and tip‐enhanced Raman scattering confirm the alignment and stability of the reactive center ...
