Sustainable Diepoxide Monomers for Polyoxazolidinone‐Based High‐Performance Thermoplastics

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
Sustainable diglycidyl ethers could replace bisphenol A diglycidyl ether (BADGE) as a building block for polyoxazolidinones, yielding high‐performance thermoplastics with similar thermal and mechanical properties. Owing to their outstanding mechanical, thermal, and chemical properties, polyoxazolidinones, which are accessible from the reaction of ...

Effect of Cu and CuP Additions on the Microstructure and Nanoindentation‐Based Fracture Behavior of CoNiAlSi Ferromagnetic Shape Memory Alloys

Advanced Engineering Materials, Volume 28, Issue 19, 7 October 2026.
Cu and combined Cu–P microalloying refine the microstructure and enhance the nanoindentation‐derived fracture resistance of CoNiAlSi ferromagnetic shape memory alloys without suppressing the martensitic transformation. Comparative SEM, DSC, and nanoindentation results reveal that the CuP‐containing alloy provides the most balanced response, achieving ...
