Phonon Engineering in Ultrathin Sn Films
When embedded in multilayer structures, ultrathin Sn layers demonstrate strongly modified vibrational density of states (VDOS). This allows engineering a drastic increase of the Lamb‐Mössbauer factor fLM$f_{\text{LM}}$ and thereby of the cross‐section for coherent excitation of the ultrasharp nuclear resonance of 119Sn$^{119}{\rm Sn}$. This enables the

A weighted damping strategy for improving the adaptability of converter to weak grid
Active damping can significantly improve the adaptability of converter to weak grid, however, when the PCC (point of common coupling) voltage harmonics are used for active damping control, the suppression ability of the system on the background harmonic ...

Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
