Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Deep-Ultraviolet Beam Homogenizers: Phase-Modulated Metalens vs. Space-Modulated Chromium Thin-Film

Photonics
Deep-ultraviolet (DUV, 193 nm) tools for lithography and precision micromachining are often limited by beam-profile nonuniformity, which degrades critical-dimension control, line-edge roughness, and process windows.

Transparent Deformable Thin Film Electric Heater for Stable and Accurate Control of High Temperatures

Advanced Functional Materials, EarlyView.
Au/GaOx‐based transparent heaters combine high optical transmittance and low sheet resistance with exceptional thermal stability up to 521°C for over 6 h. The interfacial GaOx layer suppresses dewetting of Au and enhances adhesion, ensuring mechanical robustness during deformation and reliability for real‐world applications including grilling ...
