Raman spectroscopy used like a GPS to map toughening in zirconia

By Eileen De Guire / August 22, 2011

Polarized confocal Raman spectroscopy can be used to observe in situ ferroelastic switching of ceria-stabilized zirconia. Credit: Bolon and Gentleman; JACerS GPS is a great tool. It can guide you turn-by-turn to your city’s shopping mall. It is, in fact, an “in situ” device and observes your location in real time. Once there, however, you…
