Researchers Bend Light Through 'Crystal Ball' To Carve Nano-Volcanoes (image) North Carolina State University Share Print E-Mail Caption Researchers from NC State University are able to carve nanoscale "volcanoes" by scattering light through a polymer "crystal ball" onto a photo-reactive thin film. The structures hold promise for new drug-delivery technologies. Credit Chih-Hao Chang, North Carolina State University Usage Restrictions Image credit must be given.
