Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Designing Thermally Stable DNA Hydrogels via Entropically‐Driven Acridine Intercalation

Macromolecular Rapid Communications, EarlyView.
Environmental variables are shown to systematically tune the network dynamics of entropy‐driven, acridine‐based DNA‐intercalating supramolecular hydrogels. Adjusting the buffer composition, ionic identity, and salt concentration impacts electrostatic screening and counterion release of the DNA backbone, offering a powerful handle to tune elasticity and

Reprocessable Disulfide‐Based Vitrimers with Adhesive Properties

Macromolecular Rapid Communications, EarlyView.
A dual‐curing strategy combining UV‐induced thiol–ene polymerization and thermal thiol–epoxy curing was used to prepare disulfide‐based vitrimer networks with reprocessable, recyclable, and adhesive properties enabled by dynamic disulfide exchange. ABSTRACT A family of disulfide (S–S) containing thiol–vinyl–epoxy dynamic networks are presented.

Transferable Hot‐Deformation Flow‐Curve Modeling Across Steels Through Transfer Learning

Materials Genome Engineering Advances, EarlyView.
We propose a transferable sequence model that moves steel hot‐deformation ML beyond the “one‐case, one‐model” paradigm. Pretrained across compositions/windows and personalized with four extreme‐condition curves, it improves accuracy and robustness in 10‐fold evaluation.
