Dr. Aindow’s research involves the study of microstructural development in engineering materials using, primarily, electron microscopy techniques. He directs the IMS Microscopy Laboratory facilities, which include optical microscopes, scanning electron microscopes, transmission electron microscopes and a dual-beam FIB/SEM. These facilities are being used in a wide range of IMS programs.
Dr. Aindow’s current programs include:
Oxide Scale Development in Coated High-Temperature Alloys for Solid-Oxide Fuel Cells Interconnects (with E.Sun, UTRC) – The objective of this program is to develop a fundamental understanding of the interactions between conductive oxide coatings and the high-temperature alloy substrates to which they are applied. Such coatings are required in SOFC interconnects to prevent the egress of chromia species that can poison the cell, but the complex mass transport and interfacial phenomena are not well understood. In this GOALI program we are producing model coatings, with carefully controlled microstructures and morphologies, to enable us to perform critical experiments that reveal the influence of various process and operational parameters on the oxide scale development. (Funded by NSF).
Self-Healing, High-Reliability Electrical Contacts for Military Applications (with S.P. Alpay) – In this program we are developing alloys that form native oxides with inherently high electrical conductivity. This can be achieved extrinsically via acceptor/donor doping, intrinsically by developing mixed oxidation states that facilitate polaron/electron hopping, or by phase separation giving conductive veins within the oxide. The objective is to produce materials that will form more reliable and more economic electrical contact materials without the need for the environmentally damaging plating processes in use for current technologies (Funded by UConn/ARL).
Structural Amorphous Metals – This multi-investigator program led by Pratt and Whitney has the aim of developing new high strength Al alloys from vitreous precursors. High-resolution and energy-filtered transmission electron microscopy are being used to elucidate the microstructural development in these new alloys. (Funded by DARPA)
Engineered Nano-Composite Oxides for High Durability Missile Domes (with E. Jordan, M. Gell and B. Cetegen)- This multi-investigator program led by Raytheon has the aim of developing new high strength oxide materials for infra-red window applications. The approach being used by the UConn team is to apply the solution precursor plasma spray process to form composite oxides with microstructures that cannot be formed readily using more conventional ceramic processing routes (Funded by DARPA.)
“The Effects of Impurities onFuel Cell Performance and Durability” (with T. Molter, S. Suib, J. Tang, W. Chiu and U. Pasaogullari) – This large multi-institution program is studying the effect of various air-side impurities on the performance and lifecycle of polymer electrolyte membrane fuel cells (Funded by DOE).
In addition to these main programs, extensive collaborations are underway with other faculty to exploit the potential of transmission electron microscopy in the characterization of nanoparticulate or nano-structured materials. These include studies of:
Heteroepitaxial ferroelectric thin films (with S.P. Alpay, UConn).
Metal-loaded carbon aerogels and derivative structures (with C. Erkey, Koc University).
Mesoporous manganese oxide materials (with S.L. Suib, UConn).
