I will be collaborating with Palo Alto Research Center (formerly Xerox PARC) on a Department of Energy (DOE) grant shooting for enhanced properties in lead-free piezoelectric materials.  We will apply high-throughput (HT) processing and characterization techniques on piezoceramics. This unique HT data will enable materials informatics approaches to guide our experiments towards higher performance systems.  Figure.  […]
