NEWS IN BRIEF: Rice professor finds new electron observation method

---

The process involves the attachment of a single all-carbon molecule, or buckyball, to a microcopic metal tip. The findings show that electrons, which scatter in wavelike patterns around known defects on a graphite surface, were imaged in almost exact agreement to theoretically predicted electron scattering patterns.

Associate Professor of Electrical and Chemical Engineering Naomi Halas and graduate student Kevin Kelly headed the research team.

"The C60 molecule (buckyball) acts as a filter to image certain things that metals can't," Halas said. "This demonstrates we can image molecular scale objects in an energy selective fashion."

The results of the study appear in the Sept. 6 issue of Science .
