X-ray Analysis
The Use of X-Ray Powder Diffraction (XRD) and Vibrational Spectroscopic Techniques in the Analysis of Suspect Pharmaceutical Products
July 01, 2020
Spectroscopy
Here, we compare XRD and FT-IR for analysis of suspect counterfeit pharmaceuticals to determine how the techniques can be used in a complementary fashion.

Applying EDXRF to Agricultural Analysis
November 01, 2019
Special Issues
EDXRF offers potential advantages over ICP-OES for elemental analysis in agriculture. Karen Daly and Anna Fenelon of the Agriculture and Food Development Authority of Ireland spoke to us about their work investigating agricultural applications of this technique.
Studying Gallstones and Kidney Stones with WDXRF
November 01, 2019
Special Issues
The accumulation of heavy and toxic elements in gallstones and kidney stones can be studied using WDXRF spectroscopy. Here, Vivek K. Singh of Shri Mata Vaishno Devi University in India talks about his work using this technique to understand the formation and content of these stones in the body.
Total-Reflection X-Ray Fluorescence Analysis (TXRF)as a Powerful and Cost Competitive Technique for Surface Chemical and Trace Element Analyses
November 01, 2019
Special Issues
Total-reflection X-Ray fluorescence analysis (TXRF) and grazing-incidence XRF (GIXRF) may be applied for surface and bulk trace element analysis of thin-layered systems. Burkhard Beckhoff of the Physikalisch-Technische Bundesanstalt (PTB) in Germany spoke to us about his recent work in this field.

Serial Femtosecond Crystallography (SFX) combined with an X-ray Free Electron Laser (XFEL) for Determination of Protein Structure with Reduced Sample Volume
March 11, 2019
Special Issues
Serial femtosecond crystallography is a promising new technique for protein structure determination, where a liquid stream containing protein crystals is intersected with a high-intensity X-ray free electron laser beam that is 109 times brighter than traditional synchrotron X-ray sources. We were recently able to interview Prof. Alexandra Ros, a FACSS Innovation Award winner from the 2018 SciX conference regarding her research work on this subject.
Advances in Stress Measurement with Portable X-Ray Diffraction: Uncertainties in Normal and Shear Stress Determination on Mild Steel Pipe
November 01, 2017
Special Issues
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.
Recent Developments in Small-Angle X-Ray Scattering
November 01, 2017
Special Issues
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.
EDXRF Analysis of Sulfur and Trace Element Content in FAMEs
November 01, 2017
Special Issues
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.
