Mark your calendar and please join us for the ND Energy Faculty Luncheon Fall 2023 Seminar Series from 12:30-1:30 p.m. in B01 McCourtney Hall. This series highlights specific research topics with talks by Notre Dame faculty followed by group discussions focused on (1) cross-disciplinary basic research needs, (2) potential avenues for external and internal collaborations, (3) funding sources to target, and (4) 'follow-up actions' that we can track. All interested faculty are invited to attend. With your active engagement and participation, we hope to have a stimulating and inspiring exchange of ideas and explore new directions for cross-collaborations. Please respond to the calendar invitation by 9:00 a.m. the Monday before each seminar to ensure a sufficient number of lunches. If you have any questions, please contact Dr. Subhash L. Shinde.

Abstract

The development of new materials and their compositional and microstructural optimization are essential in regard to next-generation technologies such as clean energy and environmental sustainability. However, materials discovery and optimization have been a frustratingly slow process.

In this talk, I will present our research on creating high-throughput combinatorial printing method capable of fabricating materials with compositional gradients at microscale spatial resolution. In situ mixing and printing in the aerosol phase allows instantaneous tuning of the mixing ratio of a broad range of materials on the fly, which is an important feature unobtainable in conventional multimaterials printing using feedstocks in liquid–liquid or solid–solid phases. We demonstrate a variety of high-throughput printing strategies and applications in combinatorial doping, functional grading and chemical reaction, enabling materials exploration of doped chalcogenides and compositionally graded materials with gradient properties. The ability to combine the top-down design freedom of additive manufacturing with bottom-up control over local material compositions promises the development of compositionally complex materials inaccessible via conventional manufacturing approaches. The next phase of research will focus on leveraging the fabrication freedom and data-rich nature of HTCP, along with machine learning- and artificial intelligence-guided strategies, which are expected to accelerate the discovery and development of a broad range of materials with intriguing and unprecedented properties for emerging applications.
