Hamidreza and Tulsi’s publish in Journal of Applied Physics their results on caloric response of ferroelectric materials. In this paper, they describe how adiabatic temperature changes can be enhanced by combining external stresses and electric fields. See Selected Publications.
Two new publications on Catalysis Mechanisms
Dr. Sanjubala Sahoo has been working with Prof. Steven Suib (Director – Institute of Materials Science) and his group in Chemistry on providing modeling support on the mechanisms of two separate processes in catalysis. The findings of these studies were recently published in ACS Catalysis and the Journal of CO2 Utilization. See Selected Publications.
Publication in Journal of Materials Science
Tumerkan Kesim and Haibo Yu (Prof. Aindow’s group) publish in Journal of Materials Science on deformation mechanisms in Ag3Sn-Cu3Sn intermetallic alloys.
Publication in Nanoscale
Yomery Espinal in collaboration with Prof. Nakhmanson’s group and colleagues at Argonne National Labs publishes in Nanoscale on the intrinsic size effect in ferroelectric nanoparticles.
Fu-Chang Sun Defends PhD Thesis!
Fu-Chang Sun successfully defends his PhD Thesis entitled “Modeling of Structural, Elastic, and Polar Properties of Organic and Inorganic Ferroelectrics“. Congratulations Dr. Sun!!!
Two Papers in Acta Materialia
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.
Boot up for the 2016 Fall semester
Group members gathered at Ted’s restaurant to relax and prepare for the upcoming semester.
Electrocaloric Properties of Relaxor 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.
Acoustic Detection and Modeling of Phase Transitions at the Nanoscale
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 work on multilayer ferroelectrics published in Acta Mater
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…
