ChBE Seminar: Functional Inorganic Materials for Magnetism and Oxygen Storage Speaker: Efrain E. Rodriguez, Chemistry and Biochemistry Professor, University of Maryland Title: Functional Inorganic Materials for Magnetism and Oxygen Storage Abstract: Dr. Rodriguez's group focuses on the synthesis and structural studies of compounds broadly known as functional inorganic materials. In this seminar, he will focus on two categories of materials we design and synthesize: quantum materials and oxygen storage materials. The first category broadly encompasses superconductors and magnetic materials. In this seminar he will cover layered metal chalcogenides intercalated by a variety of species that control the functionality of the quantum material. Our design strategy is to stack different metal chalcogenide layers using molecular complexes to guide their stacking and orientation. For the second category of materials, Dr. Rodriguez will cover oxygen storage materials (OSMs), which can readily upload and release oxygen molecules into the environment and therefore can replace air as a reactant. Many OSMs are essentially sub-stoichiometric metal oxides that can accommodate a large amount of oxygen site vacancies in their crystalline lattices. Potential applications include gas separations, fuel combustion, fuel conversion, and three-way catalysis. The group explores complex metal oxides such as perovskites that can overcome challenges in stability under cycling. To understand how OSMs evolve under realistic working conditions, they have performed a series of in-situ diffraction experiments at both synchrotron x-ray and neutron facilities. Some of the in-situ work with OSMs will be presented in this seminar. This Event is For: Campus |
