Walking the wire: Real-time imaging helps reveal active sites of photocatalysts

Nanoscale photocatalysts are small, man-made particles that harvest energy from sunlight to produce liquid fuels and other useful chemicals. A new imaging solution developed at Washington University in St. Louis reveals the significance of a particular structural feature — clusters of oxygen vacancies — in achieving high photocatalytic activity.

Arrokoth close-up reveals how planetary building blocks were constructed

William B. McKinnon, professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, led one of three new studies that together provide a far more complete picture of the composition and origin of Arrokoth. The new research published in Science points to the resolution of a longstanding scientific controversy about how such primitive planetary building blocks called planetesimals were formed.
