Solvent‐Free Phase Separation of Polystyrene‐block‐poly(2‐hydroxyethyl methacrylate) Forming Freestanding Photonic Films

Advanced Materials Interfaces, Volume 13, Issue 1, 7 January 2026.
This work presents a scalable, eco‐friendly approach to forming microstructured block copolymer (BCP) films within 15 min through hot pressing. This process enables phase separation even for high‐molecular‐weight BCPs, which are often trapped in spherical structures using time‐consuming solvent processes.

Controlling Selectivity at the First Hydrogenation Level: Synthesis of 3‐Hydroxyisoindolines by Heterogeneously Silver‐Catalyzed Monohydrogenation of Phthalimides

Advanced Science, Volume 13, Issue 2, 9 January 2026.
3‐Hydroxylactams are obtained from phthalimides through a heterogeneous catalyzed chemoselective hydrogenation, able to stop the process at the first hydrogenation level. By using a rationally designed [Ag/Al2O3] recyclable solid nanocatalyst, a wide range of cyclic hemiamidals are accesed through a full atom‐economical reaction that preserves (hetero ...

A review on kinetic models of dynamic recrystallization for magnesium alloys

Journal of Materials Research and Technology
Mg alloys are the lightest metallic structural material with tremendous application value. Dynamic recrystallization (DRX) is the most important grain refining and texture weakening mechanism for Mg alloys.
