Biography

Dr. Theresa Windus joined the faculty at Iowa State University in August 2006 as a full Professor. She earned her Ph.D. from Iowa State University in 1993 and did post-doctoral research at Northwestern University. Theresa was also the Director of Computational Chemistry/Training at Ohio Supercomputer Center and the Computational chemistry lead at the Wright Patterson Air Force Base Major Shared Resource Center. Before joining Iowa State University, she was the manager of the Molecular Science Software Group and the Visualization and User Services group in the Molecular Science Computing Facility in the Environmental Molecular Sciences Laboratory of Pacific Northwest National Laboratory.

Quantum Mechanics Basics and Applications in Developing Heavy Element Extractants

Quantum mechanics as expressed as electronic structure theory is a key player in understanding chemistry and the essential properties of chemical reactions.  This talk will give an introduction to the basic underpinnings of electronic structure methods include Hartree-Fock, basis sets and correlation methods.  Then the application of these methods and others will be discussed in the context of developing extractants for critical materials.  Critical materials are elements that are essential for technological advances, but that are subject to supply disruptions.  Many of these critical materials are necessary for clean energy devices such as wind turbines, solar panels and electric vehicles.  Of particular interest to the Department of Energy sponsored Critical Materials Institute are lanthanide metals such as neodymium, europium, terbium, and dysprosium.  However, these metals can be extremely difficult to separate from one another in the extraction processes and, therefore, new extractants that selectively bind one metal over another are required to make the process more efficient and cost-effective.  Towards that end, we are using computer aided molecular design to determine new potential extractants that will cut down on the experimental expense of designing an extractant.
