In November, Professor Stefano Curtarolo and colleagues published a paper in the journal Advanced Materials about a new technology they developed for use in archaeology. The technology uses infrared spectroscopy to obtain spectral “fingerprints” of minerals, allowing scientists to quickly distinguish between manmade and natural minerals in the field. It can be used, for example, to tell the difference between calcite from manmade plaster and calcite in limestone. Curtarolo is associate professor of mechanical engineering and materials sciences and physics.
