Reconfigurable Acoustofluidic Microvortices for Selective Microcargo Delivery
Advanced Science, EarlyView.This work introduces a frequency‐encoded, reconfigurable acoustofluidic system that overcomes the low throughput and poor selectivity of conventional micro‐delivery methods. By exploiting discrete microbubble resonances to program adaptive microvortex modes, the platform enables real‐time switching and selective guidance of microscale payloads through ...

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials
Advanced Science, EarlyView.ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

Broadband Achromatic Programmable Electromagnetic Camouflage via Fluidic‐Accessible Metasurface
Advanced Science, EarlyView.A fluidic access metasurface enables dynamic, broadband electromagnetic illusions. By physically reconstructing conductive patterns with liquid metal, the metasurface achieves real‐time, pixel‐level control over phase dispersion. This allows for the programmable generation of arbitrary strong scattering point arrays, effectively deceiving high ...
