Argonne Physicist, Saul Lapidus’ expertise is in the structural characterization and analysis of materials through powder X-ray diffraction and pair distribution function analysis.
Lapidus’ work with JCESR and the Energy Frontier Research Center (EFRC) project focused on the in-operando/in-situ phase transitions in cathode materials and the solvation structure of magnesium ions in electrolytes through the use of PDF analysis. This expertise dovetails with his development and operations of the high-resolution powder diffractometer at the Advanced Photon Source, which allows for this level of advanced and detailed characterization.
