A Distributed Bragg Reflector Interface for Filter‐Free Fluorescence Spectro‐Microscopy With High Spectral Tunability

physica status solidi (a), Volume 223, Issue 8, 22 April 2026.
An all‐dielectric TiO2/SiO2 distributed Bragg reflector is engineered as a substrate‐integrated optical filter, enabling filter‐free fluorescence spectro‐microscopy. Nanometer‐scale layer control aligns excitation suppression and emission reflection for specific fluorophores, achieving high‐contrast imaging at sub‐monolayer coverage.

Microporous Microgel Assemblies Facilitating the Recruitment and Osteogenic Differentiation of Progenitor Cells for Bone Regeneration

Advanced Functional Materials, Volume 36, Issue 31, 16 April 2026.
There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

A Lightweight Training-Free Image Enhancement Method for Traditional Sikka Ikat Motifs Using Log-Gabor Enhanced CLAHE (LGE-CLAHE)

Engineering, Technology & Applied Science Research
Image enhancement is essential to make subtle motifs in traditional Sikka ikat more visible, where uneven illumination and complex woven textures often hinder effective contrast enhancement. To address this challenge, this paper proposes a training-free and computationally lightweight image enhancement method, termed Log-Gabor Enhanced Contrast-Limited
