Description
Wenhao Yuan, Zhilong Wang, and Fengqi You read the life story of dying metal catalysts from still photos, in a 2026 study. Catalyst particles lose power as they wander and merge, a process called sintering. Watching that happen live is costly, so most labs see only the end state under a microscope.
Their trick, called pseudotime, orders snapshots of gold particles at many ages as if they were frames of one film. The ordering shows that the gap between particles rules their fate: below a clear threshold distance, particles drift and merge, while beyond it they stay put. Live tracking in a gas cell confirmed the threshold within a hair and let them predict sintering with 92 percent accuracy. Spacing particles out thus becomes a design rule for longer-lived catalysts.
