Catherine Niu, a professor at the College of Engineering of the University of Saskatchewan in Canada and co-author of this paper, spoke to Spectroscopy about how she and her associates used X-ray photoelectron spectra and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy analysis in their research.

Investigating Adsorption of Carbamazepine with Adsorbents Developed from Flax Shives with X-ray Spectroscopy

Harishchandra Singh, Graham King and associates have employed high energy synchrotron X-ray diffraction (HE-SXRD) experiments and an analytical model in order to predict the yield strength of cerium-modified super duplex stainless steel (SDSS) subjected to various cold- and cryo-deformation. Spectroscopy recently had the opportunity to discuss the experiments and the findings with Singh and King.

Quantitative Prediction of Yield Strength of Highly Alloyed Complex Steel Using High Energy Synchrotron X-Ray Diffractometry

In the past 20 years, spectrometers have shrunk dramatically in size, and this shrinking has been achieved with only modest performance reductions in sampling versatility, spectral range, spectral resolution, and signal-to-noise.

Spectrometers in Wonderland: Shrinking, Shrinking, Shrinking

Portable X-ray fluorescence was used to analyze the archaeological remains of an Underground Railroad station to gain a clearer understanding of the construction phases it underwent during the 19th century.

In these studies, wavelength dispersive X-ray fluorescence (WDXRF) was used to examine differences in the elemental composition of agricultural samples, comparing healthy and diseased samples of okra, papaya, and rice. Both the mineral nutrient profiles (macro and micronutrients) and toxic metals were examined, revealing common patterns.
