Florida A&M Research Team Advances Renewable Energy Studies Using ACCESS Supercomputers

November 10, 2023

Nov. 10, 2023 — A team of Florida Agricultural and Mechanical University (FAMU) researchers recently utilized ACCESS allocations on Stampede2 at the Texas Advanced Computing Center (TACC) and Expanse at the San Diego Supercomputer Center (SDSC) at UC San Diego to model reactions on catalyst surfaces that have the possibility of producing renewable and clean energy and fuels. Their findings were recently published in a Physical Chemistry – Chemistry Physics Journal paper entitled Density Functional Theory Study of Bulk Properties of Transition Metal Nitrides.

Assistant Professor of Physics Shyam Kattel, Associate Professor of Chemistry Beni Dangi, recent Ph.D. graduate Damilola Ologunagba (now a data scientist at Intel) and physics undergraduate student Michael Lynn authored the paper.

“ACCESS allocations allowed us to use supercomputers to model complex chemical processes otherwise not possible as we don’t have access to these high-performance machines on our campus,” Kattel said. “Stampede2 and Expanse gave us the power to gain atomic-level insight into how materials work and how chemical bonds are formed and broken – and share that with our students and postdoctorate researcher.”

The team specifically conducted first-principles density functional theory (DFT) calculations and microkinetic modeling to gain a fundamental atomic-level understanding of the reactions on catalyst surfaces for both research and education purposes.

“Working on supercomputers allowed me to generate data for my doctorate work, which was focused on modeling the chemical reactions on metal carbides and nitrides-based catalysts,” Ologunagba said. “Being able to use ACCESS resources enabled me to learn how to run expensive quantum chemical calculations using the Vienna ab-initio simulation package (VASP) on Stampede2.”

“Our work on ACCESS supercomputers at TACC and SDSC is not just a theoretical pursuit but a practical and impactful endeavor that can pave the way for a sustainable and greener energy economy, benefiting society and the planet as a whole,” said Kattel.

The calculations mentioned by Ologunagba not only allowed her to conduct research for her own graduate dissertation but also to share that knowledge with other graduate and undergraduate students at Kattel’s research group and across the Florida A&M campus.

“These types of scenarios are exactly what we are all about at ACCESS,” said John Towns, ACCESS Coordination Office principal investigator. “One of our main goals for this National Science Foundation program is to provide resources to institutions across the country that are not only using supercomputing for research but also educating our future generations.”

Additional publications by the team include the following:
