Dental Microwear Texture Analysis on Radular Teeth

open access: yesAdvanced Materials Interfaces, EarlyView.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.

Bismuth Nanogratings With Narrow Plasmon Resonances for Dynamic Polarized Color Generation and Colorimetric Sensing

open access: yesAdvanced Optical Materials, EarlyView.
Bismuth nanogratings are fabricated by pulsed laser deposition onto the nanostructured silver and polycarbonate surfaces of DVDs. They display spectrally‐narrow plasmon resonances yielding vivid colors, which are strongly sensitive to the polarization of light, angle of incidence, nature of the underlying surface and of the surrounding medium (air or ...

Scalable Design and Optimization of Reconfigurable Sb2S3 Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Scalable optimization methodologies are developed for reconfigurable Sb2S3 Huygens metasurfaces by combining localized phase‐match and overlap‐integral cost functions that account for inter‐element coupling. The framework enables computationally efficient design of large‐area, dual‐state flat optical devices with arbitrary wavefront transformations ...
