Advanced Materials, EarlyView.We developed a bioinspired mechano‐intelligent Janus bandage (MIB) with a hydrophobic flat exterior and a hydrophilic interior featuring gecko‐mimicking wedged microstructures, fabricated via micromolding and anisotropic plasma treatment. The MIB dynamically synchronizes adhesion and contraction, enabling precise force modulation.

Advanced Materials, EarlyView.Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

Digital Microneedles for Multiplexed Transdermal Sensing via Fluorescent QR Codes
Advanced Materials, EarlyView.Digital fluorescent microneedles encode biochemical information in skin into scannable QR codes through threshold‐activated probes that generate binary on/off signals. By transforming analog fluorescence into discrete digital patterns, this platform enables calibration‐free, multiplexed transdermal sensing of physiologically relevant biomarkers ...

Sofistas griegos: nuevos maestros, viejos maestros
Ars Brevis, 1996 Con frecuencia la filosofía académica ha asignado un valor negativo a los sofistas griegos, contemporáneos de Sócrates, que surgen en Atenas en el siglo V a.C. En oposición a esta imagen tradicional, el presente ensayo aporta elementos para construir una interpretación en la que los sofistas son caracterizados como pensadores de gran capacidad, e ...

Advanced Materials, EarlyView.A nano‐interception strategy disrupts pathogenic fibroblast–macrophage crosstalk in chronic heart failure. Scalable Prussian blue nanoparticles selectively sequester CCL2 via ultrahigh‐affinity binding, preventing CCR2+ macrophage recruitment and breaking a key fibro‐inflammatory circuit. This approach demonstrates robust efficacy in murine and porcine
