The idea for the competition came about two years ago, when Mick Thomas, a facility manager at CCMR who runs one of the microscopy labs, noticed that students were taking remarkable microscopic images, but many were never published. Other first-place winners were Wenlong Cheng, for an image of gold nanoparticles manipulated with DNA James Loudon, who captured a lattice-like pattern in manganite (MnO3) and Matthew Lloyd, for his image of thin films of organic molecules following exposure to a solvent vapor.Ĭhoosing from 25 submissions, faculty judges also picked a handful of honorable mention winners in such categories as "most unusual," "most artistic" and "best caption." Held periodically throughout the academic year, the contests solicit often stunning and always interesting images taken on CCMR equipment, including electron and optical microscopes. To better her understanding of nacre, the iridescent substance found in seashells, Cornell engineering graduate student Ellen Keene used a scanning electron microscope to study crystals of calcium carbonate, the nacre's fundamental material.īy capturing an image of two strikingly different polymorphs, or crystalline patterns, of calcium carbonate on the edge of a broken silicon wafer, Keene also won herself a first-place award in the National Science Foundation-funded Cornell Center for Materials Research (CCMR) fourth microscopy imaging contest.
