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: The turn of the worm: Viral infection

The first structure of a virus known to naturally infect nematode worms has been revealed by researchers using X-ray diffraction. Given the nematodes rank in molecular biology as a useful model for processes in humans, the structure could offer many new clues as to how viral infection occurs in humans too, thus presenting novel targets for the pharmaceutical therapies.

Elemental Bio-Imaging by Means of Tabletop Micro-XRF

Micro-XRF spectrometry is a well-established method for the non-destructive elemental analysis of inhomogeneous materials. Its full potential for the analysis of biological samples, however, is only just starting to be utilized.

Combining X-ray and neutron scattering data for lattice dynamics measurements with theoretical models improves our understanding of the well-known insulator vanadium dioxide and its transition to a metallic state.

Soft X-ray back-diffraction, at angles near and exactly equal to 90°, has been explored with a novel high-resolution Si(220) multi-bounce back-diffraction monochromator and an ultra-thin Si(220) crystal as the sample.

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.
