International Workshop on Improving Data Quality and Quantity for XAFS Experiments (Q2XAFS 2011)

An introductory overview to the special issue papers from the Q2XAFS Workshop in this issue of the journal.

X-ray-induced photo-chemistry and X-ray absorption spectroscopy of biological samples

X-ray-induced photo-chemistry of metal sites within biological molecules is a concern for X-ray absorption spectroscopy, X-ray crystallography and other techniques in which samples are illuminated with X-rays. The effects of X-ray-induced photo-chemistry are reviewed and the methods used to mitigate these in X-ray absorption spectroscopy are outlined.

X-ray absorption spectroscopy at a protein crystallography facility: the Canadian Light Source beamline 08B1-1

The Canadian Macromolecular Crystallography Facility beamline 08B1-1 at the Canadian Light Source has added the capability to perform X-ray absorption spectroscopy on crystal samples.
