Assistant Chair (Academic), School of Mechanical & Aerospace Engineering
Prof. Su’s research interests are in applying microsystem technologies, nanoscale thin film materials engineering, and nano-patterning technologies at the interface of energy conversion devices, specifically fuel cells and electrolyzer cells. She pioneered in development of high power density nano thin film oxide fuel cells at low operating temperature and keeps leading cell performance in the literature. Her research interests include low temperature solid oxide fuel cells, micro/nano fabrication, nanoionics, and thin film energy materials. Her research group focuses on developing new electrode and electrolyte materials and nano-engineering of cell components via thin film deposition technologies, design and fabrication of scalable micro-SOFCs, and study of reaction kinetics between cathode and nano thin film electrolyte interface, all together with an ultimate goal of commercializing a practical device for SOFCs below 500°C.

Prof Su has been active on additive manufacturing (AM) using stereolithography (SLA) and DLP for 3D/4D printing polymers and polymer composites. Currently, her research group is focusing on formulation of novel SLA/DLP functional photopolymer resin, 3D printing using nanocomposite photopolymers, study of the impact of 3D printing process parameters on printability and mechanical properties, 4D Printing of shape changing materials and its characterization. She has been developing photopolymer formulation with renowned chemical and medical device companies for specific applications.

US 2018/0159162 A1: Energy Conversion Device And Method Of Forming The Same (2020)
Abstract: Various embodiments may provide a method of forming an energy conversion device. The method may include forming an electrolyte layer on the first surface of the semiconductor substrate. The method may also include forming a cavity on the second surface of the semiconductor substrate using a deep reactive ion etch. The method may further include enlarging said cavity by carrying out one or more wet etches so that the enlarged cavity is at least partially defined by a vertical arrangement comprising a first lateral cavity surface of the semiconductor substrate extending substantially along a first direction, and a second lateral cavity surface of the semiconductor substrate adjoining the first lateral cavity surface. The method may include forming a first electrode on a first surface of the electrolyte layer, and forming a second electrode on a second surface of the electrolyte layer.
