Q&A: Dean Kumar and the ‘drone’ sightings
Picture of a drone flying lit nighttime cityscape

For more than a month, residents in New Jersey, parts of Pennsylvania, and New York have spotted unidentified flying objects, which local residents refer to as “drones,” hovering over neighborhoods, critical infrastructure and even restricted sites. To learn more about the mysterious flying objects, Penn Today spoke with local expert Dean Vijay Kumar of the School of Engineering and Applied Science.

    Mapping molecular arrangements to pave the way for better catalytic systems
    Bright spots represent individual catalyst molecules captured under cryogenic conditions to prevent clustering.

    Eric Stach of the School of Engineering and Applied Science and colleagues used neural networks to better identify the characteristics of catalysts that drive the creation of liquid fuels from sunlight. Shown here: The arrangement of a catalyst molecule, as observed under cryogenic conditions. The bright spots represent individual or small groups of molecules immobilized on a surface and the cryogenic temperature helps minimize clustering caused by the electron beam during imaging, allowing scientists to study the molecule’s distribution more accurately.
