Veronica Ayen and Christian Bonanni have joined Dr. Alpay Research Group. Veronica and Christian are undergraduate students in Materials Science and Engineering.

Tulsi Patel and Reza Khassaf, working with Prof. Aindow and Prof. Nazanin Bassiri-Gharb, deposit PZT on additively manufactured Inconel. Alumnus Dr. Misirlioglu explains the origin of the low dielectric loss in graded ferroelectrics. 

Reza’s work with collaborators from United Technologies Research Center, Georgia Tech and Jozef Stefan Institute (Slovenia) shows that intrinsic adiabatic temperature changes in relaxor-FEs are substantial and relatively temperature insensitive. Our findings were recently published in Journal of Materials Chemistry C.

Our colleagues at Georgia Tech and Oak Ridge demonstrate acoustic detection in nanoscale volumes by the use of an atomic force microscope. Elastic changes in volume are measured by detecting changes in resonance of the cantilever. Reza has provided theoretical guidance, modeling the electric field driven phase transformation using Landau theory.

Reza’s experimental work, in collaboration with Prof. Aindow’s group, shows that there is a dielectric anomaly in fairly thick ferroelectric-eparaelectric bilayers. Read more…

The group had a great lunch at Geno’s Grille to celebrate the Holidays. Research talk was strictly forbidden. We are looking forward to another great year!
