About the Workshop (APS training course)
In conjunction with the 2021 APS Users Meeting, NSF’s ChemMatCARS is offering a two-day school on data analysis for X-ray studies of liquid interfaces. The school is designed primarily for graduate students, postdoctoral researchers and young scientists with some expertise in liquid interface science.
Synchrotron X-ray scattering is the most powerful probe of near-atomic-level structure at liquid-vapor and liquid-liquid interfaces. Over the past 20 years, X-ray scattering from liquid interfaces has led to many key discoveries in physical, chemical, biological, and technological systems. However, the complex data analysis combined with the lack of a standard software package has prevented this technique from being adopted more widely across scientific communities. To address this barrier, we are presenting an in-depth workshop on analyzing synchrotron X-ray scattering data from liquid surfaces and interfaces.
The enrollment is limited (~30 participants) with priority given to applicants who have prior experience in the study of liquid interfaces and currently use or plan to use liquid interface scattering in their research. Prior to attending the school, participants are required to install and familiarize themselves with the data analysis software developed by NSF’s ChemMatCARS. We will provide a combination of interactive lectures and student activities. Topics include the theory underlying both measurement techniques and data analysis, application of analysis techniques to real data, and experimental methodology.
Liquid Interface Instruments
The Liquid Surface X-ray Scattering Program at NSF’s ChemMatCARS operates a full suite of X-ray surface scattering techniques. Capabilities permit measurement of atomic, molecular, and mesoscopic ordering at liquid interfaces. Techniques offered include
- Resonant and non-resonant reflectivity
- Grazing-incidence diffraction and small angle scattering
- Surface fluorescence
- Surface diffuse scattering
- Fast techniques, such as grazing incidence diffraction in the 1D pinhole geometry.
From 2016 LSXS school student: “For me the most beneficial part was learning the theory behind the X-ray experiments, getting an intuition for what the data means and how to interpret it, and learning about how they’re applied to various systems/applications. I also learned about the kind of research that other users are doing.”
The workshop is supported by NSF grant #1834750, “NSF’s ChemMatCARS: A synchrotron X-ray national facility for chemistry and materials research at the Advanced Photon Source,” Matthew Tirrell (Principal Investigator), Mark Schlossman, Ka Yee Lee, Theodore Betley, and Jason Benedict (Co-Principal Investigators).
