From the Director
We are excited to announce that the Air Force Research Lab (AFRL) will be supporting the operation of the new Materials Solutions Network at CHESS, MSN-C, with $7.1Million .  MSN-C will provide dedicated access to two new X-ray beamlines, the Structural Materials Beamline (SMB) and the Functional Materials Beamline (FMB) , for Air Force and other Department of Defense researchers as well as original equipment manufacturers. MSN-C is the latest subfacility in our newly formed partner-funded model, joining CHEXS and MacCHESS .
CHESS continues to successfully develop important new techniques that expand the capabilities at CHESS and synchrotrons around the world. In this issue, you can read about newly-minted PhD David Agyeman-Budu’s research on the potential high-yield fabrication of X-ray transmission mirror optics and CHESS staff scientist Stan Stoupin’s development of CVD diamonds for focusing and monochromatizing high energy X-rays .
Among recently published research performed at CHESS, we showcase the structural characterization of cellulosic membranes optimized for energy harvesting . After infiltrating electrolyte into cellulosic membranes, the ionic conductor exhibits a thermal gradient ratio (analogous to the Seebeck coefficient in thermoelectrics) more than twice the highest value reported until now.
In this newsletter, we again highlight the people of CHESS and their adventures and experiences beyond the lab. This month we are featuring Katie Moring, our Operations Manager , who counts cycling among her many interests outside the lab. At CHESS, she and her team of CHESS operators work tirelessly to make beamlines and experimental systems function at peak performance and support users to make the best out of every beamtime. Next month, when CHESS resumes user operation, visiting scientists can see first-hand how Katie, her team, and all of the CHESS staff transformed the facility, and maybe chat about the best cycling routes beyond the lab!

The new Materials Solutions Network at CHESS (MSN-C) will provide dedicated access to two new X-ray beamlines at CHESS for Air Force and other Department of Defense materials researchers, and original equipment manufacturers. High-intensity, high-energy X-ray beams available at the newly upgraded CHESS facility will enable breakthroughs in materials and designs for military components.
Last month, Linda Sapochack, NSF Division Director for the Division of Materials Research (DMR), Clark Cooper, Senior Advisor for Science and Head of the Office of Multidisciplinary Activities in the NSF Directorate for Mathematical and Physical Sciences, and NSF Program Director Guebre X. Tessema visited  CHESS to see the newly upgraded facility.
Beyond the Lab with Katie Moring: CHESS Operations Manager: The hills of Ithaca are a haven for road bike enthusiasts. The rural roads offer the rider a backdrop of farm life, glimpses of Cayuga Lake, and enough climbs to keep you healthy and invigorated. If you travel these scenic paths, you may come across a group of riders known as the Gorges Gals, journeying the same climbs, and geared up for the 20-30 mile ride. Usually, at the front of the pack is Katie Moring. Katie helps organize the weekly ride - with sometimes up to 40 attendees - and urges others to get involved.

When: Oct. 14-15, 2019

Where: Physical Sciences Building, Cornell University, Ithaca, NY

Workshop Goals:
-Inform the manufacturing industry on cutting edge research with in situ and ex situ characterization capabilities and how they have been helpful in solving industrial challenges.

-Provide invaluable direction to the characterization community on where to focus resources with regards to experimental development for model validation or part qualification/acceptance.

-Identify experiments in a formal report that can meet current industrial needs and that will stretch current characterization capabilities.
Potential high-yield fabrication of x-ray transmission mirror optics: XTM Optics development at CHESS has illustrated their potential as X-ray optics for high-pass harmonic selectors and tunable wide bandpass monochromators. With further instrumentation development, they can be potentially applied to high heat load filtering applications at synchrotrons.
Diamonds are for focusing and monochromatizing: Chemically vapor deposited diamond crystal as medium resolution X-ray monochromator: CVD diamonds in X-ray monochromators enables affordable compact systems operable in a laboratory with conventional X-ray sources, under extreme conditions as high radiation heat load optics at synchrotrons, or, possibly, as compact remote X-ray instrumentation for planetary missions.
Heat Harvesting with Cellulosic Membranes Wood-based ionic conductors are flexible, lightweight, biocompatible and based on sustainable materials that can enable large-scale manufacture and suitable for low-grade thermal energy harvesting.
