    The multi-camera array microscope is essentially an array of many miniaturized digital microscopes, which acquire synchronized video in parallel. A variety of algorithms allow the researchers to fuse the video data acquired by the microscope into final gigapixel-scale composites.
    Duke University researchers expect a new multi-camera array device to revolutionize the study of genetics, neurological disorders, and other diseases.

    This illustration from Guo’s Lab shows the interaction between a perovskite material (cyan) and a substrate of metal-dielectric material. The red and blue pairings are electron-hole pairs. Mirror images reflected from the substrate reduce the ability of excited electrons in the perovskite to recombine with their atomic cores, increasing the efficiency of the perovskite to harvest solar light.
    A team of University of Rochester Institute of Optics researchers, led by Chunlei Guo, improve light conversion efficiency of perovskites 250% by pairing them with a metal platform...
