Atomic Imaging of Tooth Enamel
September 1, 2020 | Terry Sharrer
Materials scientists as Northwestern University had experience with atom probe tomography, while those at Cornell were versed in low temperature (e.g. -298 degrees F) electron microscopy. Together they worked to examine the nanoscale structure of tooth enamel, which is sensitive to electron beams, but far less so as extremely low temperatures. What they found were structural flaws that acids worked upon in causing tooth decay. MORE
