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

open access: yesRare 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.

Unsymmetrical β‐Fused Blatter Radical Zinc Phthalocyanines

open access: yesChemistry – A European Journal, Volume 32, Issue 4, 23 January 2026.
Herein, we report the first synthesis of a new class of β‐fused Blatter–Zn phthalocyanines featuring a persistent radical π‐system, π–π‐driven crystal packing, and SOMO‐centered redox behavior. Single‐crystal X‐ray diffraction shows packing motifs dominated by centrosymmetric π‐π dimers.
