To test the accuracy of residual stress measurements made with portable X-ray devices, measured normal and shear stresses were compared with the applied (true) values for accuracy assessment. From those results, practical measurement and analysis protocols for precise and accurate stress measurements are proposed.

There has been a resurgence in the application of small-angle X-ray scattering for a large range of problems in materials science. This article highlights experimental requirements and applications, with examples drawn from protein solutions, porous structures, and polymers.

The EDXRF method described here is a quick and economical procedure to check samples for their oxygen content to ensure that the material used for diesel fuel blending is really FAME-based and not mineral-oil based.

David R. Chettle, a professor at McMaster University in Hamilton, Ontario, Canada, uses X-ray fluorescence spectroscopy for the in vivo measurement of toxic elements in human subjects, with the goal of developing devices that can be used to investigate the possible health effects of toxin exposure. He recently spoke to us about his research.
