Acoustic Wavefront Shaping Using Ultrahigh Phase Resolution Metamaterial
A Bilateral Symmetrical T‐shaped (BST) acoustic metamaterial unit cell capable of achieving a high phase resolution of π/36 radians at 8000 Hz is introduced. The approach enables tunable wavefront control through simple rotational adjustment of BST, which offers an alternative to the conventional complex metamaterials unit cell design and a way for ...

Tuning Charge‐Separated State Lifetimes in Perovskite Nanocrystal‐Perylenediimide Hybrids
Functional perylenediimides with varied spacer lengths surface engineer CsPbBr₃ perovskite nanocrystals, yielding hybrid materials with new properties. Time‐resolved techniques reveal photoinduced charge separation from perovskite nanocrystals to perylenediimides, with microsecond‐lived charge carriers. Spacer length modulates charge carrier lifetimes,
