A collaborative team of materials scientists and theoretical chemists provide hybrid perovskite nanoparticles that are high-efficiency light emitters by using a comprehensive defect-suppression strategy. New research details how a class of electroluminescent materials, key components of devices such as LED lights and solar cells, can be designed to work more efficiently. Published in Nature Photonics, the […]

Nearly pain-free microneedle patch can test for antibodies and more in the fluid between cells. Blood draws are no fun. They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too. Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial […]

Each group participating in the C-STAR III evaluation this year has been assigned a series of translations for human grading. The grading assignments for each group are split into 5 files, listed under the group name. In order to keep the overall file length manageable for a single grader in a single grading session, each […]
