Chemoselective Sequential Polymerization: An Approach Toward Mixed Plastic Waste Recycling
Advanced Functional Materials, EarlyView.Inspired by biological protein metabolism, this study demonstrates the closed‐loop recycling of mixed synthetic polymers via ring‐closing depolymerization followed by a chemoselective sequential polymerizations process. The approach recovers pure polymers from mixed feedstocks, even in multilayer formats, highlighting a promising strategy to overcome a

Recent progress in primitive polyester synthesis and membraneless microdroplet assembly
Biophysics and Physicobiology, 2023 While it is often believed that the origins of life required participation of early biomolecules, it has been recently proposed that “non-biomolecules”, which would have been just as, if not more, abundant on early Earth, could have played a part.

Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites
Advanced Functional Materials, EarlyView.Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.
