Tawanda Zimudzi, part of the technical research staff at Penn State's Materials Research Institute, pours liquid nitrogen into a cryo-trap to clear contaminants in a vacuum chamber before starting a new molecular spectroscopy study. Molecular spectroscopy is the study of a material's stability as molecules undergo change.
