Biography

Nicola H. Perry is an Assistant Professor in the Department of Materials Science and Engineering at the University of Illinois, an Affiliate of the Frederick Seitz Materials Research Laboratory, and a WPI Assistant Professor in the International Institute for Carbon-Neutral Energy Research (I2CNER) of Kyushu University. She received her Ph.D. in Materials Science and Engineering from Northwestern University in 2009, working with Thomas O. Mason on interfacial transport, permittivity, and defect behavior in nano-ionics for solid oxide fuel cells. After this she joined the Energy Frontier Research Center for Inverse Design as a postdoctoral fellow developing p-type transparent conducting oxides for photovoltaic applications and synthesizing ￿missing materials,￿ using a computationally-led discovery process. In 2012 she began splitting her time between Japan (at I2CNER) and the U.S. (at MIT, in the Department of Materials Science and Engineering, with Harry L. Tuller), as a postdoctoral researcher (I2CNER) and visiting scholar (MIT). In 2014 she was promoted to the WPI Assistant Professor position in I2CNER, where she ran the ￿electro-chemo-mechanics￿ laboratory in the Electrochemical Energy Conversion division, taught international students, and continued as a Research Affiliate at MIT. Research at this most recent stage focused on mixed ionic and electronic conducting oxides for high temperature electrochemical energy conversion and storage. She joined the University of Illinois in January 2018.

Research Statement

Electro-chemo-mechanically active oxides enable a wide array of energy, processing, sensing, and electronic applications, but limitations in their charge transport, surface reactivity, and chemical expansion hinder efficiency and durability. A fundamental understanding of these point defect-mediated properties needs to be developed in order to enable rapid, rational design of optimized solid state ionics for improved device performance. Particularly, there is benefit in moving beyond conventional electro-chemical studies to consider the coupling between electrical, chemical, and mechanical states of materials, such as the lattice strain occurring upon non-stoichiometric composition changes during operation (chemical expansion). Our recent work has been focusing on development of design principles for fast oxygen surface exchange kinetics and the resulting chemical expansion in perovskite-structured ceramics that ￿breathe.￿ We measure surface oxygen exchange kinetics on model thin films fabricated by pulsed laser deposition, using in situ ac-impedance spectroscopy and a novel optical transmission relaxation technique. Controlled variation of overall film defect chemistry, outermost surface chemistry, orientation, and microstructure has enabled a better understanding of the relative importance of each. We study chemical expansion behavior across multiple length scales using in situ X-ray and neutron diffraction, thermogravimetric analysis, and dilatometry, with comparison to atomistic computational simulations. Such studies have enabled identification of structural and operational factors that can be applied to tailor chemical expansion behavior. We apply ac-impedance spectroscopy, equivalent circuit analysis, and microstructure models like the nano-Grain-Composite Model to evaluate and separate local interface/bulk ionic and electronic transport and polarization in bulk ceramic, thin film, heterostructured, and nanostructured materials. Overall, approaches to lower the chemical expansion coefficients (for durability) and increase the surface exchange kinetics and ionic/electronic transport (for efficiency) are being actively researched.
