Piezoelectric‐Metal Phononic Crystal Enabling GHz Tunable Ultrahigh Q Quasi‐BIC Mode

Advanced Science, EarlyView.
This study introduces a piezoelectric–metal phononic crystal design based on suspended LiNbO3 thin film that realizes quasi‐BIC resonance. The device achieves GHz operation with an ultrahigh quality factor (≈6.5 × 104) and efficient electrical tunability at low voltage.

Ferroelectric Properties of Bilayer MoS2/WS2 Heterostructure Modulated by Twist Angle

Advanced Science, EarlyView.
The study reports the precise control of interlayer twist angles in the bilayer MoS2/WS2 heterostructure. The ferroelectric properties of MoS2/WS2 heterostructure can be significantly modulated by designing twist angles, resulting from the distortion of polar symmetric regions induced by Moiré patterns.

Strong Lattice Softening Induced by Atomic Mismatch in Meta‐Phase Thermoelectrics

Advanced Science, EarlyView.
This work demonstrates the validity and universality of atomic mismatch‐induced lattice softening across three metaphase systems: Ag8Sn(S,Te), Cu2(S,Te) and Mg2(Si,Sn). Abstract Conventional strategies for suppressing lattice thermal conductivity κL typically focus on maximizing phonon scattering to reduce phonon mean free path.

The Circadian Transcription Factor CLOCK Modulates Oxidative Stress Resistance via the ACHL–Relish Axis in Drosophila

Advanced Science, EarlyView.
This study identifies the circadian transcription factor CLOCK (CLK) as a key regulator of oxidative stress resistance in fruit flies. CLK controls immune responses by driving rhythmic transcription of an RNA‐binding protein‐Achilles (ACHL) in the fly brain, which post‐transcriptionally represses the NF‐κB homolog Relish, limiting immune activation and
