Comparison of Directional and Diffused Lighting for Pixel-Level Segmentation of Concrete Cracks
Visual inspections of concrete infrastructure in low-light environments require external lighting to ensure adequate visibility. Directional lighting sources, where an image scene is illuminated with an angled lighting source from one direction, can ...

Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis
Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.

A dye‐based photoinitiator acting as a structure‐directing element, guides the formation of a cholesteric polymer network that behaves as a chirped photonic structure with dissipative chiral coupling. Photopolymerization freezes a depth‐dependent helical pitch, broadening the Bragg resonance spectrum.

Tandem organic solar cells with optimized ternary acceptor engineering achieved a power conversion efficiency of 15.53% and enabled a high‐voltage mini‐module (Voc 6.11 V). Integration into a bias‐free PV‐EC system further demonstrated efficient solar‐to‐ammonia (STA) conversion (97% Faradaic Efficiency, 4± 2% STA efficiency), highlighting scalable ...
