Organofluorines can be surprising
Recent study, which has shaken up the field of organofluorine chemistry, was the cover article in the May 2012 issue of Chemical Science. A large part of the study included precise x-ray crystallographic measurements and was performed at the ChemMatCARS facility at the APS.

A New book on liquid surfaces and interfaces scattering
A new book, titled "Liquid Surfaces and Interfaces: Synchrotron X-ray Methods" will become available soon. The book, which should meet and existing need for a source of information about liquid surface theory and techniques, is partially based on work done at ChemMatCARS.

2012 Liquid Surface X-ray Scattering School (LSXS-12)
This coming fall the surface scattering facility of ChemMatCARS, together with the APS, will be hosting the LSXS-12 School, a workshop on the theory and practice of synchrotron based liquid surface x-ray scattering. The workshop should prove invaluable to novices in the field.

Undergraduate Researcher Brian Leahy
Authors PRL Paper
ChemMatCARS student employee Brian Leahy has gotten an exceptional head start on a career in science: The recent University of Chicago grad (B.A. physics, 2009) is the first author of a paper in the leading journal Physical Review Letters. Coauthored by CARS staff scientists and collaborators in the University of Chicago Chemistry Department, the paper explores the fundamental physics of folding in thin films.

Secrets of the Lacewing's Silk
Researchers from Australia’s CSIRO used wide-angle x-ray scattering to answer long-standing questions about the structure of lacewing silk. Female lacewings use delicate silk “stalks” to to suspend their eggs out of the reach of predators.

A Stable Open Framework with Wide Open Spaces
The ChemMatCARS advanced crystallography station was used to determine the structure of a metal-organic framework compound with a unique stucture that combines large cavities (> 20 Å) and small openings (< 20 Å). The structure is achieved by a novel synthesis strategy. Porous materials frameworks with open structures are potentially useful for a wide range of applications, such as gas storage, catalysis, and drug delivery.

ChemMatCARS used to solve structure of material that doubles wavelength of light
A promising light-conversion material almost went unrecognized because it crystallized only in long, thin spines that couldn't be characterized by normal x-ray diffraction. With microcrystal diffraction at ChemMatCARS, the team solved the structure, which pointed the way to the material's unique properties.

Nailing down the exciton in LiF
Exitons are a key element in the functioning of semiconductors and insulators, and understanding their structure and how they form and behave in different materials is vitally important to the development of new materials and technologies. Work at ChemMatCARS has helped settle a 70-year-old controversy about the true nature of the exciton in alkali halide insulators, the type of material in which excitons were first observed.

Research puts new wrinkle in study of materials folding under pressure
Scientists at the University of Chicago and the University of Santiago in Chile have explained, for the first time, the physics that governs how thin materials at scales millions of times different in thickness make the transition from wrinkles into folds under compression. The study stems from a research program at the University of Chicago aimed at understanding the characteristics of lung surfactant, a microscopically thin membrane that facilitates breathing. But the findings would apply both to the design of foldable electronics and to the production of synthetic lung surfactant for therapeutic uses. Read Science article ›
