Recently accepted in Nanoscale, this paper explores phase transitions of polarization topology in single spherical ferroelectric nanoparticles of PbTiO3 and BaTiO3. This work highlights some interesting dielectric properties of these systems that emerge as a size-dependent phenomena and shown that they can be manipulated by adjusting the materials combination of the configuration. Serge and John investigated this system with our collaborators at Argonne National Laboratory and with Pamir Alpay and his graduate student Yomery Espinal here at UConn.

Our group received funding from Stanadyne for a summer project dedicated to FEM-based modeling of fuel injector operation. This project will involve cooperation between our “senior” graduate students and some new SoE undergraduates who are just getting their feet wet with serious research.
A few days ago we were notified that John will be receiving the highly prestigious U.S. Department of Energy (DoE) Office of Science Graduate Student Research (SCGSR) award that will allow him to conduct his PhD research at one of the DoE national labs. John will be spending his summer at Argonne working with our collaborator Dr. Olle Heinonen. Congratulations to John!
This JVSTA paper was chosen as one of the most actively downloaded ones after its publication. Here are the links to the official press release and the UConn/MSE highlight.
A new article featuring Rebecca Stern, who is currently an MSE senior doing research with the group, was recently published on the MSE web site. Congratulations to Rebecca!
This project was mostly done by Siliang Chang, who is the student of Prof. Christos Takoudis at UIC. Seungbum Hong and
