Entropy Decoding the Fundamental Law of Phase Competition in Glass Formation

open access: yesAdvanced Science, EarlyView.
We validate the integration of intermetallic and eutectic phases as initial phases for composition design. The phase competition mechanism in glass formation is quantitatively clarified based on the melting entropy of competing phases. Glass‐forming ability is modulated by tuning phase competition via the melting entropy of initial phases.

Programmable Elastic Wave Control Via Mechanical‐Acoustic Interaction in Bistable Metamaterials

open access: yesAdvanced Science, EarlyView.
A mechanically programmable metamaterial based on mechanical‐acoustic interaction enables reconfigurable elastic wave control through bistable state switching. Spatial encoding of peak and valley states tunes band structures and transmission, achieving low‐frequency vibration suppression, waveguiding, and energy localization.
