A nanometer measures just 1/100,000 the width of a human hair, but the chemical reactions that take place at that level bear significant implications for scientists, engineers, medical practitioners and more. Dr. Zhenrong Zhang, associate professor of physics, is illuminating the nanoscale through the development of a powerful nanoscale microscope. In this Baylor Connections, she shares how the invention can lead to more accurate medical diagnoses, cleaner sources of energy and more.
