  3. 31. The Autonomous Formulation Lab: Industrial Formulation Optimization Combining SAS & ML
    Tyler Martin (NIST)
    16/10/2023, 14:00

    Societal need and regulations are driving reformulation of materials and products so that they reduce the pace of climate change and cause less harm to humanity and the environment. While scattering methods (SAXS, SANS, WAXS) are workhorse techniques for characterizing formulations, they are challenged to keep up with the resultant rapid pace of redesign. Consumer and industrial formulations...

    16/10/2023, 14:30

    At the 2017 canSAS workshop I was first introduced to the concept of applying Machine Learning (ML) algorithms to analysing scientific datasets. Since then I have moved towards adopting an increasing number of ML based techniques for data analysis with a view towards developing truly adaptive experimentation.

    Lofty words.

    Wondrous ideals.

  5. 21. Inferring Lyotropic Phase Topology through Scattering using Deep Learning
    Wei-Ren Chen (Oak Ridge National Laboratory)
    16/10/2023, 15:00

    Lyotropic phases, which encompass structures like lamellar or sponge formations, constitute a significant category within the realm of soft matter. The characterization of these lyotropic phases has often relied on the technique of small angle scattering. The impact of curvatures on the diverse lyotropic mesomorphism has been widely acknowledged. However, conventional regression analysis based...

  6. 26. Machine-learning-assisted Analysis of Small Angle X-ray Scattering
    Shun Yu (RISE Research Institute of Sweden)
    16/10/2023, 15:30

    Small-angle X-ray scattering (SAXS) is a powerful characterization technique for nanoscale structures in materials. The analysis of SAXS is a modeling-heavy process to find a plausible structure model that corresponds to the measured scattering intensity due to the inherent “phase problem” of the X-ray detection. Despite various scientific computing tools to assist the model selection, the...

    Wiebke Koepp (Lawrence Berkeley National Lab)
    16/10/2023, 17:40

    For users to make informed decisions about adapting their experimental setup or inspect the decisions of an autonomous experiment, it is essential to extract and visualize relevant features from scattering patterns as they are collected. Making use of browser-based technologies further enables remote, device-independent and installation-free access, as well as providing standards-based...

    Jan Skov Pedersen (Aarhus University, Denmark)
    17/10/2023, 16:30

    To increase the information content of small-angle scattering data, it is usual to perform contrast variation small-angle neutron scattering (SANS) with one or more of the components deuterated and by varying the composition of the solvent using mixtures of per-deuterated and non-deuterated solvents. Additional information can be added by combination with small-angle X-ray scattering (SAXS)...
