Researchers continue to find new uses for portable X-ray fluorescence and portable Raman techniques in the field. Mary Kate Donais, an associate professor in the Department of Chemistry at Saint Anselm College, recently spoke to us about her experiences with these techniques at an archaeological excavation site in Italy.

Koen Janssens, professor of chemistry at the University of Antwerp (Belgium), uses synchrotron radiation-based X-ray fluorescence (XRF) to analyze historic works of art. In a recent study, he used various spectroscopic techniques, including several X-ray methods, to reveal the process by which the yellow paint in some of Vincent Van Gogh?s paintings darkened over time.

This November, NASA's Mars Science Laboratory will be launched on a mission to Mars that will deploy a new rover, called "Curiosity." Curiosity will include several analytical instruments, including "CheMin," which uses X-ray diffraction (XRD) and also has limited X-ray fluorescence (XRF) capabilities.
