Ambient‐Light‐Activated Rewritable Optical Patterning in Transparent Long‐Afterglow Garnet Ceramics

Laser &Photonics Reviews, EarlyView.
This work demonstrates sunlight‐activated rewritable optical information storage in transparent long‐afterglow Y3Al2Ga3O12:Ce (YAGG:Ce) garnet ceramics fabricated via solid‐state sintering with tetraethyl orthosilicate (TEOS) as a sintering aid. By integrating ambient‐light operability, reversibility, and high optical clarity in a robust ceramic host ...

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel

River Research and Applications, EarlyView.
ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...
