Devin Grabner – 2023 ALS User Meeting Invited Speaker & Planning Committee Member

Devin Grabner played a dual role at this year’s Advanced Light Source (ALS) User Meeting & Visioning Workshops. As a member of the Users’ Executive Committee, he helped organize the week’s plenary talks, events, and workshops, which celebrated the 30th anniversary of the first light and discussed the future of the ALS. In addition, Devin was invited to present his cutting-edge research on the development of a Liquid In-Situ Resonant Soft X-ray Scattering technique during the “X-Ray Scattering for Complex Materials and Interfaces at the ALS: Data Acquisition and Analysis” tutorial on the first day of the User Meeting. The meeting tutorials and visioning workshops were valuable opportunities to exchange ideas and insights on the latest developments in the field.

One of the highlights of the event was a lunch meeting with Dr. Dava Keavney, the Program Manager for X-ray Light Sources at the U.S. Department of Energy – Scientific User Facilities. Devin was among the group of researchers invited to discuss current U.S. Department of Energy policies and positions related to X-ray Light Sources such as the ALS.

Collins Group Presents at 2019 APS March Meeting

Thomas Ferron, Victor Murcia, Terry McAfee, and Brian Collins all presented at the 2019 APS March Meeting in Boston, MA. Victor, Terry, and Brian all presented in the Focus Session on “Advanced Morphological Characterization in Polymers” where Brian gave the Invited Talk for the session.

Victor presented his work on combining NEXAFS measurements and DFT of molecules to create more accurate optical models for analysis of polarized resonant soft X-ray scattering (RSoXS). Terry discussed his work with developing in-situ capabilities in RSoXS showing quantitative characterization of polymer micelle structure and dynamics without using chemical labels.

Thomas presented in the Focus Session on Organic Electronics where he discussed his recent paper on charge separation affected by molecular mixing at the donor-acceptor interface in organic photovoltaic devices.
