Advancing Informational Gain from Synchrotron Techniques in Subsurface Science
Location: Trinity Conference Room

  • As technical developments have enabled improvements in the spatial and temporal resolution, contrast, and detection capabilities of synchrotron techniques, the complexity of the scientific questions and systems that can be targeted has also increased. Advancements in recent years have opened the opportunity for interrogating the surface structure and chemical composition of nanoparticles and microbial-/organo-mineral interactions (HRFD-XAS, STXM, nanoSIMS), as well as for obtaining time-resolved 3D-images of intact rock/soil cores, biological samples (CT, TXM, SAXS), and high-resolution 2D chemical maps (micro/nano-XRF) at large scale and with sophisticated image analysis methods. Significant advancements also have been made in statistical and computational approaches for analyzing and abstracting information from complex data sets, such as images. In some cases, these methods are relatively new to the field.  One such example is application of machine learning to 2D and 3D x-ray imaging data acquisition and analysis. With more in-depth, efficient and less labor-intensive image analyses, informational gain and throughput could increase dramatically.  This symposium aims to:
    • bring light to the advancements to synchrotron techniques and computational analyses that impact subsurface science
    • Stimulate innovative discussions about the opportunities these advancements bring to subsurface research
    • identify future opportunities and steps to increase the informational gain from existing techniques
  • Organizers:  Kristin Boye and John Bargar/SLAC SSRL

  • We invite scientists, post-doctoral researchers, and graduate students to contact workshop organizers (Kristin BoyeJohn Bargar) to contribute ideas to this symposium in these and related areas. We are looking forward to a scientifically exciting session!

Defects and Interfaces in Batteries Probed by Synchrotron X-ray Techniques

Location: Panofsky Auditorium

  • Rechargeable battery technologies have ignited significant breakthroughs in contemporary society, including but not limited to revolutions in transportation, electronics, and grid energy storage. The remarkable development of rechargeable batteries can be largely attributed to in-depth efforts to understand and improve defects and interfaces in batteries. There are, however, still intimidating challenges of lower cost, longer cycle and calendar life, higher energy density, and better safety for large-scale energy storage and vehicular applications. Further progress with rechargeable batteries may require new chemistries (lithium-ion batteries and beyond) and a better understanding of materials electrochemistry in the various battery technologies. In the past decade, advancement of battery materials has been complemented by new analytical techniques that are capable of probing battery chemistries at various length and time scales. Synchrotron X-ray techniques stand out as one of the most effective methods that allows for nearly nondestructive probing of materials characteristics such as electronic and geometric structures with various depth sensitivities through spectroscopy, scattering, and imaging capabilities. This workshop will cover synchrotron X-ray based analytical tools (scattering, spectroscopy and imaging) and their successful applications (ex situ, in situ, and in operando) in gaining fundamental insights into these scientific questions. The workshop will also highlight current progress of advanced experimental and computational methodologies, such as high-throughput data acquisition, data mining and machine learning, which have emerged as effective and efficient methods for converting the experimental data into scientific findings.
