Artificial Symbiosis for Bulk Production of Bacterial Cellulose Composites

open access: yesAdvanced Materials, Volume 38, Issue 13, 3 March 2026.
Co‐cultivation of the cellulose‐producing bacterium with the microalga enables bulk formation of bacterial cellulose under static incubation, with photosynthetically active oxygen‐generating sites throughout the medium. This symbiotic platform supports 3D cellulosic constructs with geometries dictated by the vessel shape.

Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance

open access: yesAdvanced Optical Materials, Volume 14, Issue 12, 25 March 2026.
The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

Quantum Nanoplatelet Pixelation at 3000 PPI for Enhanced Color Conversion in Microdisplay Applications: Direct Integration on MicroLEDs

open access: yesAdvanced Optical Materials, Volume 14, Issue 9, 6 March 2026.
Integration in very high‐resolution full color microdisplays (for AR/VR applications) of quantum nanoplatelet‐based 3D patterns as color converter microsubpixels assembled on top of blue‐emitting microLEDs. ABSTRACT High‐brightness, full‐color microdisplays with sub‐5 µm pixel pitch are key for next‐generation augmented and virtual reality applications.
