An interdisciplinary workshop on ways to leverage and advance x-ray tools for time-resolved and in-situ studies for structural, engineering, and geological materials.
Structural, engineering, and geological materials are critical to a range of technologies including civil infrastructure, transportation, and defense. Understanding the link between a material’s microstructure and its performance under relevant thermo-mechanical conditions is key to improving materials design, processing, and life-cycle scheduling. High-energy x-rays, such as those at CHESS, are a powerful tool for probing the microstructure of these materials. Ongoing advances in light source properties (e.g. flux and beam time structure), detector technology, and novel sample environments offer the opportunity to extend studies of materials processing and performance to encompass faster timescales and an increasingly rich array of physical phenomena. Meanwhile, advances in modeling and data science provide the tools to grapple with large datasets and gain an understanding of the fundamental physics at play.
We are planning an interdisciplinary workshop that will explore ways to leverage and advance x-ray tools for time-resolved and in-situ studies on these materials, focusing on the following systems, techniques and computational tools:
Materials and systems:
- Additive manufacturing
- Ceramics
- Cements
- Metals
- Rocks and geological materials
Experimental tools:
- High-energy x-ray diffraction microscopy
- X-ray powder diffraction
- Micro-computed tomography
- Single-bunch time-resolved imaging and diffraction
Computational tools:
- Machine learning
- Workflows for big data
- On-the-fly data reduction and pre-processing
Organizing committee:
Nikolas Bouklas (Cornell), Mostafa Hassani (Cornell), Ryan Hurley (Johns Hopkins), Darren Pagan (Penn State), Kate Shanks (CHESS)
The workshop will be held in a fully virtual format via Zoom.
