Many industrial processes use solid catalysts to accelerate chemical reactions in gases or liquids. The activity of these heterogeneous catalysts often varies considerably from site to site across their surfaces. If scientists were able to identify highly reactive sites precisely, they could improve the catalysts by redesigning them to include more of those sites.

Aliaksandr S. Bandarenka and coworkers at the Technical University of Munich have now devised a scanning tunneling microscopy (STM) technique that . . .
