A new model predicts how lightning would sweep across any airplane, including those with experimental designs. The tool generates a zoning map of the plane, showing which sections require more or less lightning protection. 

LEDs are essential components in near-eye displays like virtual reality and augmented reality headsets and smart glasses, along with electronics like cameras and medical equipment. In Applied Physics Letters, researchers use AC power to drive an LED device instead of DC power, significantly reducing the complexity of fabricating nanoscale LED devices. In addition to simplifying the design, the researchers developed key improvements throughout the fabrication process and overall device performance.

Singlet fission (SF) offers a way to boost energy conversion in photosensitive materials by splitting energy from a single high-energy photon into two lower-energy excited states. In a recent study, researchers at Kyushu University developed a set of pressure-responsive SF-active molecules with flexible polar linkers. Their experiments revealed that adjusting pressure and changing the solvent can reversibly control SF rates, paving the way for advanced energy conversion materials and phototherapeutic applications.

A new material has been used to create a gel that can repair and regenerate tooth enamel, opening up new possibilities for effective and long-lasting preventive and restorative dental treatment.
