Gregory Freihofer wins 2nd place at the SAMPE CAMX student paper competition
Argonne National Laboratory is a multidisciplinary research center by the Department of Energy for various fields in science and engineering.The labs contain specialized instrumentation and equipment that is not readily available to most facilities. With the help of various researchers and employees at ANL, the lab members of Raghavan Research Group perform high temperature x-ray diffraction on thermal barrier coatings with the synchrotron located in Chicago. Below is a list of Journal Papers and conference proceedings that involved experimentation at Argonne National Labs.
