Mechanically Compliant and Optically Tunable Metal Oxide‐PDMS Nanocomposite Thin Films as a Platform for Flexible Photonic Integration

Advanced Materials Interfaces, EarlyView.
This study demonstrates polydimethylsiloxane (PDMS) nanocomposite thin films incorporating ZnO and TiO2 nanoparticles, optimized using response surface methodology. The films exhibit tunable refractive index, high transparency, low optical loss, and sub‐MPa mechanical compliance.

Cu and Cu‐30Ni Alloy as Anti‐Viral Materials for High‐Touch Surfaces: Efficacy in a Simulated Public Environment with Frequent Cleaning Practices

Advanced Materials Interfaces, EarlyView.
This study evaluates the antiviral efficacy and corrosion behavior of pure copper and Cu‐30Ni alloy on high‐touch surfaces under simulated public conditions with periodic cleaning. Copper shows faster virus inactivation due to higher ion release, while Cu‐30Ni offers better aesthetic durability.
