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.

New targets for preventative therapies of HIV infection might now be possible thanks to new studies that reveal the 'dance' of HIV proteins on the surface of the virus that are thought to be involved in the infection of human immune cells.

A procedure and calibration samples were developed for X-ray fluorescence spectrometry and scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS) analysis methods for Sn and Pb amounts in solder and coatings.

Cancer detector: Graphene solution

Researchers have used X-ray photoelectron spectroscopy and Raman spectroscopy to confirm that bioreceptor molecules attached to a graphene biosensor exposed to cancer biomarkers can reveal the presence of these markers and so might be used as a cancer detector.

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.

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.
