Catalysis by Single Metal Atoms: What is all the fuss about?
Location: Redwood Conference Rooms A/B

  • There has been rapid growth in research on catalysis by supported single metal atoms. The interest stems from the highest achievable dispersion of the metal and the highly tunable metal-support interaction, giving single metal atoms unique catalytic properties. Within the class of supported single metal atom catalysts, there are distinct types of catalyst, for example: isolated atoms on a metal oxide support, isolated atoms on a second metal nanoparticle – the so-called single atom alloys, and supported molecular complexes possessing high structural uniformity. Synchrotron-based X-ray absorption and emission spectroscopies are critical to access the structural and chemical information of these materials due to the low metal content and the absence of long-range order. In this workshop, we will cover the current challenges and future prospects in this expanding field with focus on synchrotron-based characterization methods.

LCLS-II Early Science: Part I
Location: Panofsky Auditorium

  • This workshop will focus on early science opportunities for LCLS-II, specifically the instruments NEH 2.2 (q-RIXS, XPCS), and NEH 1.3 (XPP). Speakers will be invited to present ideas of the most compelling science that will exploit these instruments in the areas of coherent imaging and scattering, nonlinear X-ray science, high-resolution time-resolve spectroscopy near the Fourier-transform limit, and time-resolved spectroscopy and scattering in the tender X-ray regime. Brief overviews of the capabilities of the instruments will be provided, and the early science process for LCLS-II will be presented.

Machine Learning for X-ray Science:  From machine optimization to experimental planning
Location: Redwood Conference Rooms C/D

  • Across the National user facilities Physicists, Chemists, Materials Scientists, Engineers and Computer Scientists are working collaboratively to adapt and develop machine learning (ML) tools to increase the efficiency of how x-rays are delivered and how science is performed at user facilities.  We propose to bring together researchers who are developing ML tools for delivering x-rays, building data analysis tools, and building artificial intelligence to design experiments.  The workshop will be designed to increase visibility and collaboration between researchers across these seemingly disparate topic areas.  Additionally, the workshop will have a secondary focus to introduce users to existing ML tools which have been developed to increase their efficiency at the user facilities, but for which they may not be aware exist.  This workshop would be followed by a broader 2-day workshop being planned in conjunction with Stanford to broadly explore how machine learning can be used to accelerate material science, with hands on demonstrations of how we can use existing data to build predictive models for future experiments.
