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.

New details of an integral component in the human body's cellular switchboard that regulates sensory and hormonal responses have been revealed by scientists using SLAC's ultrabright X-ray laser.The discovery could have broad implications on the development of more highly targeted and effective drugs with fewer side effects for high blood pressure, diabetes, depression, and even some types of cancer.

Scientists in Germany and Netherlands have taken inspiration from nature to synthesise a novel zeolite catalyst that could be used to convert natural gas to liquid fuels. X-ray absorption spectroscopy and other techniques were key to their success.

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.

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.
