Loading samples into a scanning electron microscope
University of Pennsylvania graduate student Wei-Shao Wei loads a sample into a scanning electron microscope at the Singh Center for Nanotechnology. SEM images, which provide information about a material’s surface topography and composition, were used to study the unusual shapes formed by droplets of chain-like liquid crystal molecules.
