Glassy interphases reinforce elastomeric nanocomposites by enhancing volume expansion under strain

Proceedings of the National Academy of Sciences, Volume 123, Number 16, April 2026.
Significance By adding nanoparticles to elastomers, engineers are transforming materials with the flexibility of rubber bands into composites strong enough to support a Boeing 747 on just a few pieces of tire. The physics behind this transformation has remained elusive…
