Prevention of Frost‐Driven Self‐Fracture of Ionomer‐Bound Carbon Films by Controlling Freezable Water Domain Size

open access: yesCarbon Energy, EarlyView.
Frost‐induced self‐fracturing in ionomer‐bound carbon electrodes arises from binder‐phase damage due to confined water expansion. This study shows that thermal reconfiguration reduces water uptake and restructures the ionomer nanophase, enhancing mechanical robustness under subfreezing conditions.

Thermal degradation of impact‐modified PMMA in mechanical and chemical recycling

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Poly (methyl methacrylate) (PMMA) is a thermoplastic with outstanding tensile strength, UV resistance, and a high level of transparency that has been used widely for optical applications such as glazing in the automobile industry. Mechanical recycling, the most widespread method, degrades the physical properties and prevents reusing PMMA in ...

Bio‐Based Fluorescent Epoxies: Emission Control through Molecular Packing and Phase Separation

open access: yesChemSusChem, EarlyView.
One‐pot synthesis of fluorescent coumaric and ferulic epoxies without compromising thermomechanical properties with respect to bisphenol A diglycidyl ether is studied. This study demonstrates the sustainable conversion of agricultural waste into high‐performance fluorescent epoxy resins through direct blending of coumaric acid epoxy (CE) and ferulic ...

High‐Performance Phthalonitrile Resins Partially Derived from a Furan Bio‐Based Chemical Platform

open access: yesChemSusChem, EarlyView.
Low‐melting Schiff‐base phthalonitrile resins are synthesized from a furan‐based chemical platform, providing improved processability and sustainability. Upon curing, the resins yield high‐performance thermosets with exceptional thermal stability, high char yield, and glass transition temperatures above 400 °C.
