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

open access: yesRare 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.

Porous structure of highly crosslinked styrene‐divinylbenzene copolymers

open access: yesDie Angewandte Makromolekulare Chemie, 1984
AbstractPorous structure of two series of styrene (S)‐divinylbenzene (DVB) copolymers has been studied. The copolymers were prepared by suspension copolymerization of the monomers (50 wt.‐% of DVB) in the presence of heptane‐toluene mixtures as inert diluents.

Perchloric Acid, an Effective Catalyst for Thermosetting Self‐Crosslinking Hydroxy Acrylic Resins

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 4, January 20, 2026.
Perchloric acid is an effective catalyst for the crosslinking of hydroxy acrylate resins. Its action is based on the intermediate formation of alkyl perchloric esters. Transesterification gives volatile alkyl perchlorates that evaporate to give a catalyst‐free resin.
