High-entropy materials present significant potential for numerous applications due to their unique chemistries, but such materials’ optical properties have not been studied fundamentally yet. Two researchers at Alfred University begin to fill this knowledge gap by investigating a transparent high‐entropy fluoride laser ceramic.

Metalenses, or flat surfaces that use nanostructures to focus light, are poised to revolutionize cameras, sensors, and displays—if the lenses can be mass produced. Researchers at the Harvard School of Engineering and Applied Sciences found deep-ultraviolet projection lithography can solve this production challenge.
