Outreach circuits are open

High school students Sarah McAndrews, left, from Groton Central School, and Brad Shaughnessy from Oakfield-Alabama Central School, learn, during a lab tour of Clark Hall, how Cornell grad student Vera Sazonova investigates the electrical properties of individual carbon nanotubes -- long tube-shaped molecules only a few atoms wide that may be used to build extremely small circuits. More than 40 high school teachers and students participated in the Oct. 18 on-campus workshop on the theme of circuits, hosted by the Center for Nanoscale Systems at Cornell. Charles Harrington
