student using an electron microscope to examine a piece of nacre, an extremely resilient biomaterial.

Jiseok Gim, materials science and engineering PhD candidate, demonstrates loading a sample into the JEOL 3100R05 electron microscope in the Michigan Center for Materials Characterization at the University of Michigan's North Campus Research Complex in Ann Arbor, MI on October 21, 2019. Gim is part of a research team at U-M, led by Robert Hovden, associate professor of materials science and engineering, that used electron microscopy and mechanical deformation techniques to capture visual evidence of why nacre, a long-studied bio material found in mollusk shells, is so tough.
