Recovering unrecognizably damaged 19th-century photographs with scanning x-ray fluorescence
What did the Scientists Discover?
D-line going out with a bang!
Materials were as varied as conjugated small molecules [5,10,18], pharmaceutical molecules [16], metal-organic frameworks [19], cellulose nanocrystals [7], and hybrid organic-inorganic perovskites [2,3,8,9,13] (all in GIWAXS mode) as well as monodisperse nanoparticles [1,14,17], and block copolymers, polymer membranes, and polymer brushes [4,6,11,12,15] in GISAXS mode. In GIWAXS mode length scales probed are 1-3 nm, in the GISAXS modes 2-20 nm for nanoparticles and 20-80 nm for block copolymers.
BioSAS: Advanced Applications
BioSAS: Advanced Applications
October 7, 2018, Peninsula A
Solution small-angle x-ray and neutron scattering methods are having an increasing impact in structural biology largely due to advanced hardware, data analysis and modeling. The objective of this course is to give users hands-on practical experience with a variety of software tools that provide powerful capabilities for processing, analyzing and modeling BioSAS experimental data.

XES Workshop attracts remote participants from across the globe
Encompassing both didactic lectures and tutorials as well as “hands-on” experiment time at C-line, the workshop focused on giving participants a thorough background in both the practical and theoretical aspects of x-ray emission spectroscopy (XES) and high energy resolution fluorescence detected x-ray absorption spectroscopy (HERFD XAS).
Connecting with the community in a meaningful and impactful way
Following through on intentions outlined in our 2012 NSF proposal, our team sowed the seeds and fanned the flames that ultimately led to the founding of a dedicated drop-in space where kids can build and cultivate an identity in science. Opened last October at a new low-income housing facility, Ithaca’s Free Science Workshop is providing self-directed exploration, experimentation, and engineering to these families.

BioSAXS Essentials 8 workshop introduces state-of-the-art density program
Our 8th BioSAXS Essentials training workshop drew a wide-ranging and enthusiastic crowd of 36 students, including 6 from University of Puerto Rico, 1 from Korea, 2 from Estonia and 1 from Canada. About half of the students had never collected data at a synchrotron before!
CHESS squeezes in an early Users’ Meeting prior to extended shutdown
Participants from 23 institutions and companies joined the meeting in person on the Cornell campus and online via YouTube live.
Controlling morphologies at the nano-scale
An international collaboration of the Physics Department at Technical University of Munich has established a novel and versatile approach to fine-tune the morphology and hence the functionality of thin polymer films. Prof. Christine Papadakis and coworkers changed the nano-structure of these films by annealing the films at elevated temperature and with mixtures of two solvent vapors.
