Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Advanced Functional Materials, EarlyView.Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

A Novel DFIG Damping Control for Power System with High Wind Power Penetration
Energies, 2016 Aiming at the fact that large-scale penetration of wind power will to some extent weaken the small signal stability of power systems, in this paper, the dynamic model of a doubly fed induction generator (DFIG) is established firstly, to analyze the ...

Velocity‐Tunable Exciton‐Photon Hybridization in Cathodoluminescence
Advanced Functional Materials, EarlyView.Transition‐radiation resonances in suspended thin crystals hybridise with excitonic transitions under free‐electron excitation. By tuning the electron energy, the photonic resonances are continuously detuned across the exciton states, enabling controllable exciton–photon hybridisation below the diffraction limit without altering the system geometry ...

Advanced Healthcare Materials, EarlyView.This work introduces a microsphere‐templated strategy to fabricate reprocessable PEDOT:PSS syntactic foams with tunable porosity, stable conductivity, and 3D printability. In situ PEDOT:PSS coatings create a conductive network that maintains electrical performance at high void fractions.

Advanced Healthcare Materials, EarlyView.This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...
