    Optical Tools Enable the Study of Microplastics

    Plastics have only been around since the 1950s and yet they’re everywhere: scattered in our lakes, rivers, floating on the top of oceans, and dropping to the bottom. Back in the 1950s and 60s, plastics were hailed as a useful invention, used...

    Light Research Advances Medical Diagnostics & Health

    Light technologies are increasingly contributing to our health and longevity. While, for example, cancer is among the leading causes of death worldwide, death rates for individual cancer types have declined in part due to advanced research on light...

    Thin Film Hides Objects from Infrared Detectors

    Researchers at the Chinese Academy of Sciences have developed an aerogel film made of DuPont Kevlar fibers that makes objects invisible to infrared detectors. A successful method for hiding objects from heat-sensing cameras could be...

    Perovskite NIR LED with Record External Quantum Efficiency

    Researchers at Linköping University (LiU) in Sweden have produced near-infrared (NIR) light-emitting diodes (LED) of perovskite with a record external quantum efficiency of 21.6%. Because perovskites have good light-emitting properties and...
