Quality in the Laboratory

Quality is of extreme importance for labs. However, it is often seen as the responsibility of the quality manager and its importance and impact on your own work is not always well understood. In this webinar, Peter Kootstra will reinforce how quality can improve your performance and your work satisfaction.

Last Month's Most Accessed Feature: Resistance is low: New quantum effect

In experiments using X-ray angle-resolved photoemission spectroscopy, US researchers have discovered a new quantum effect that enables electrons to move through the interior of certain materials with very little resistance.

Researchers have synthesized the antioxidant compound 4-(5-chloro-2-hydroxyphenylamino)-4-oxobut-2-enoic acid and obtained a crystal structure. The molecule has comparable antioxidant activity comparable to that of vitamin C, ascorbic acid, as well as demonstrable antitumour activity.

Noninvasive X-ray absorption spectroscopy was used to examine in vivo bromine speciation in brown and red algae, a diatom, a dinoflagellate and a natural phytoplankton sample.

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.

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.

Elemental Bio-Imaging by Means of Tabletop Micro-XRF

Date: Oct 9, 2014 - 15:00

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.
