Yildiz Group's research area is the science and technology of materials development for energy conversion applications in harsh environments. The scientific insights derived from our research impact the design of novel surface chemistries for efficient and durable solid oxide fuel/electrolysis cells, and for corrosion resistant films in a wide range of extreme environments as in nuclear energy generation and oil exploration. We have made significant contributions in advancing molecular-level understanding of the kinetics of oxygen reduction and oxidation on ionic solid surfaces. Specifically we study the effects of temperature, stress and reactive fluids on the surface reactivity and degradation by combining theoretical and experimental analyses of electronic structure, defect mobility and composition, and provide design guidelines for high-performance and durable materials.
The key findings in much of our work were obtained through our development of in situ surface science techniques in conjunction with first-principles calculations and novel atomistic simulations. We develop and implement new scanning tunneling microscopy and spectroscopy capabilities in harsh in situ conditions of temperature, reactive gasses and mechanical stresses; a first-of-its kind capability. Our computational specialization includes development of new multiscale models to overcome the timescale limitation of traditional atomistic methods while coupling to the same atomistic length scales attainable in our experiments
