X-ray @ spectroscopyNOW

The X-ray spectrometry channel covers all aspects of research into techniques using X-ray fluorescence (XRF), X-ray diffraction (XRD) and crystallography used in material science, protein analysis, art and archaeology research, environmental analysis, biotechnology and pharmaceutical analysis. 

Monthly Highlight

Last Month's Most Accessed Feature: Chocs away: X-raying chocolate bloom

An X-ray study could help explain with new clarity why the crystalline structure of chocolate changes leading to the formation of a white bloom on the surface and how that fatty bloom might be avoided.

The first steps of a novel mechanism, with a moving subgrain boundary precursor region, have been investigated on an ice single crystal using synchrotron radiation Bragg diffraction imaging.

The twinkling of heavenly bodies is well known to stargazers the world over and most are aware that atmospheric disturbances and refractive distortions are the underling of that twinkling. But, there are fluctuations in the brightness of galactic objects that are occur on a much grander and longer scale. Take active galactic nuclei, the brightest  objects in the universe. They are not lit up permanently, but rather  'flicker' on a very prolonged timescale, particularly poignantly in the X-ray...

Beating the heat: Cooler chips

For the first time, X-ray studies undertaken at the US Department of Energy's SLAC National Accelerator Laboratory have revealed an exotic material property that could allow the electronic structure to be warped so that excessive and damaging heat build up in ever-smaller computer components might be avoided.

We are proud to announce a new series of educational webinars run in collaboration with Chromedia, COAST, and SciMind, a product of the American Chemical Society. These webinars will build into a must-have set of tutorial materials for the analytical scientist.

In this article, the late Ron Jenkins, formerly of the International Center for Diffraction Data provides a brief but comprehensive overview of modern X-ray techniques.

The 1962 book, Fifty Years of X-Ray Diffraction, dedicated to the International Union of Crystallography on the occasion of the commemoration meeting in Munich, July 1962, by P.P. Ewald (editor), and numerous crystallographers has been digitized and put on the web as a free site by the ICU.

Corticosterone levels in bird eggs corrected by LC/MS, revealing previously unknown patterns

Steve Down

Jul 6, 2015

The variation of corticosterone levels in bird eggs has been measured by LC/MS, correcting the gross overestimations of immunoassays and revealing a link with the time of breeding.
