Peak‐in‐Valley Metal Nano‐Architectures via E‐Beam‐Guided Metal Oxide Redox

Advanced Functional Materials, EarlyView.
Focused electron beam irradiation of nanoelectrosprayed water‐ammonia films enables the synthesis of topologically complex metal nanostructures via solvent‐mediated metal/metal‐ion redox control. Low ammonia favors radiolytic oxidation, etching copper.

Inducing Chirality and Chiral Instabilities in Ferrogels with Homogenous Magnetic Fields

Advanced Functional Materials, EarlyView.
By pre‐aligning magnetic particles into chains, significant chiral deformations are induced by fixing the base of a cylindrical actuator and applying a homogeneous magnetic field. Subsequent base rotation can drive the system into metastable states. Further rotation or reduction of field strength triggers a chiral instability, characterized by a switch

A Comparative Analysis of Plasmonic and Dielectric Metasurface Sensing Platforms Powered by Bound States in the Continuum

Advanced Functional Materials, EarlyView.
This work reveals a fundamental trade‐off between plasmonic and dielectric metasurfaces for molecular sensing. A clear performance crossover is identified: dielectric metasurfaces excel in air, while plasmonic metasurfaces dominate in lossy solvents. These results establish design rules for infrared metasurface sensors and enable optimized performance ...
