Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, Volume 37, Issue 49, December 10, 2025.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Biomimetic and Compressible Wood Phase Change Gel With Hierarchically Aligned Lamellar Structure for Controlled Thermal Management

open access: yesCarbon Energy, Volume 7, Issue 10, October 2025.
Inspired by skeletal muscle thermogenesis, a wood phase change gel exhibiting mechano‐controlled heat release is developed. Under compression, the wood phase change gel overcomes its energy barrier, inducing its phase change from supercooling to crystallization and raising its overall temperature by around 5°C.
