Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

open access: yesAdvanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Understanding the Dynamics of Nanoparticle Formation and Evolution in Functional Oxides via In Situ SAXS/WAXS

open access: yesAdvanced Materials Interfaces, EarlyView.
In situ SAXS/WAXS enables real‐time tracking of nanoparticle formation and evolution in exsolved and infiltrated Ni‐based perovskites under reducing conditions. The combined technique captures nucleation, growth, and coarsening dynamics with high temporal resolution, providing statistically robust insights into structural and morphological ...

Could Edible Photonic Structures Be an Alternative to Traditional Food Coloring?

open access: yesAdvanced Optical Materials, EarlyView.
What if color in food came from photonic structures? This perspective introduces structural color as a potential next‐generation solution to replace conventional colorants in foods. It discusses edible photonic materials, their unique benefits, and the technological, safety, and consumer acceptance challenges that must be addressed to bring this ...

Plasmonic Metasurfaces with Structural Chirality and Pseudo‐Chirality for Enhanced Circular Dichroism and Enantiomeric Recognition

open access: yesAdvanced Optical Materials, EarlyView.
A planar plasmonic metasurface composed of asymmetric gold nanostructures is shown to exhibit both anisotropic and chiral/pseudo‐chiral optical responses. By tailoring the polarization and angle of incidence, the metasurface significantly enhances optical chirality and enables enantiospecific detection.

Phase Smoothing for Mutual Coupling Mitigation in Multifunctional Metasurfaces Designed with Diffractive Neural Networks

open access: yesAdvanced Optical Materials, EarlyView.
A diffractive neural networkdesigned metasurface operating at 86 GHz generates multiple holographic patterns by controlling the phase of subwavelength unit cells. A phase‐smoothing regularization mitigates mutual coupling, enabling accurate multifunctional wavefront shaping.
