Thiolate Salt Mediated Dynamic Silyl Ether Exchanges for Polymer Network Design and Deconstruction

Macromolecular Rapid Communications, EarlyView.
This work introduces thiolate salts as mediators for dynamic silyl ether exchange. This platform enables the synthesis of reprocessable covalent adaptable polymer networks (CANs) and allows for sterically controlled, and tunable deconstruction of silyl ether‐containing thermosets.

Cononsolvency‐Assisted Fabrication of Hydrogels and Microgels With Tunable Porosity, Diffusivity and Stiffness

Macromolecular Rapid Communications, EarlyView.
The cononsolvency of poly(dimethyl acrylamide‐co‐hydroxyethyl acrylamide) copolymers in water‐acetonitrile mixtures enables the synthesis of hydrogels with finely tuned porosity. Optimized for droplet‐based microfluidics, this approach facilitates the fabrication of porous microgels with tunable mechanical and diffusion properties, offering precise ...

Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.

A new brittle rheology and numerical framework for large-scale sea-ice models

International audienceWe present a new brittle rheology and an accompanying numerical framework for large-scale sea-ice modelling. We have based this rheology on a Bingham-Maxwell constitutive model and the Maxwell-Elasto-Brittle (MEB) rheology for sea ...

Electrospun PVA Scaffolds Containing MCM‐41/CNC Nanocomposites for Controlled Drug Release in Wound Dressings

Polymer Engineering &Science, EarlyView.
Cellulose nanocrystals extracted from Mauritia flexuosa petiole were combined with MCM‐41 mesoporous silica to create a diclofenac‐loaded hybrid nanocomposite. Incorporation into electrospun PVA scaffolds enabled controlled diclofenac release and high cell viability, highlighting their potential for localized drug delivery.

Structural and Rheological Properties of Chitosan‐Biochar Composites Prepared With Waste Biomass‐Derived Biochar

Polymer Engineering &Science, EarlyView.
Chitosan dispersions containing biochar derived from vine pruning residue showed increasing shear stress and improved thermal stability with loading. Flow behavior was described by the Bingham plastic model in all cases. These results support the valorization of agricultural waste in functional biopolymer formulations.

River Ice Processes Modelling: A Comprehensive Review

River Research and Applications, EarlyView.
ABSTRACT River ice strongly influences hydrology, hydrodynamics, and ecosystems in cold regions, with an impact on flooding, hydropower generation, navigation, and aquatic habitats. Modeling river ice processes is therefore essential for both scientific understanding and operational management.
