Author(s)
Debashish Sur, Emily Holcombe, William Blades, Daniel Foley, Brian DeCost, Elaf Anber, Jason Hattrick-Simpers, Karl Sieradzki, Howie Joress, John Scully, Mitra Taheri
Compositionally complex alloys hold the promise of simultaneously attaining superior combinations of properties, such as corrosion resistance, light-weighting, and strength. Achieving this goal is a challenge due in part to a large number of possible

What is missing in autonomous discovery: Open challenges for the community

October 16, 2023
Author(s)
Philip Maffetone, Howie Joress, Shijing Sun
Self-driving labs (SDLs) leverage combinations of artificial intelligence, automation, and advanced computing to accelerate scientific discovery. The promise of this field has given rise to a rich community of passionate scientists, engineers, and social

Why is EXAFS for complex concentrated alloys so hard? Challenges and opportunities for measuring ordering with X-ray absorption spectroscopy

October 16, 2023
Author(s)
Howie Joress, Bruce D. Ravel, Elaf Anber, Jonathan Hollenbach, Debashish Sur, Mitra Taheri, Brian DeCost
Short-range order (SRO) is a critical driver of properties (e.g., corrosion resistance and tensile strength) in multicomponent alloys such as complex concentrated alloys (CCAs). Extended X-ray absorption fine structure (EXAFS) is a powerful technique well

Self-driving Multimodal Studies at User Facilities

January 22, 2023
Author(s)
Bruce D. Ravel, Phillip Michael Maffettone, Daniel Allan, Stuart Campbell, Matthew Carbone, Brian DeCost, Howie Joress, Dmitri Gavrilov, Marcus Hanwell, Joshua Lynch, Stuart Wilkins, Jakub Wlodek, Daniel Olds
Multimodal characterization is commonly required for understanding materials. User facilities possess the infrastructure to perform these measurements, albeit in serial over days to months. In this paper, we describe a unified multimodal measurement of a

Reproducible Sorbent Materials Foundry for Carbon Capture at Scale

September 22, 2022
Author(s)
Austin McDannald, Howie Joress, Brian DeCost, Avery Baumann, A. Gilad Kusne, Kamal Choudhary, Taner N. Yildirim, Daniel Siderius, Winnie Wong-Ng, Andrew J. Allen, Christopher Stafford, Diana Ortiz-Montalvo
We envision an autonomous sorbent materials foundry (SMF) for rapidly evaluating materials for direct air capture of carbon dioxide ( CO2), specifically targeting novel metal organic framework materials. Our proposed SMF is hierarchical, simultaneously

Development of an automated millifluidic platform and data-analysis pipeline for rapid electrochemical corrosion measurements: a pH study on Zn-Ni
