Nano-what? Silver nanoparticle gel for identifying pigments

The analysis of dyes and lakes is a challenging task for conservation scientists. Nanoparticles and nanocomposites have become a powerful tool to increase the power of spectroscopic techniques, exemplified with SERS. This method not only improves the detection limit but also allows non-invasive analyses. Continue reading Nano-what? Silver nanoparticle gel for identifying pigments

From Mars to the museum: The application of full-field X-ray fluorescence (XRF) to the study of a Caillebotte painting

X-rays help researchers understand the elemental profile of an artwork. A new X-ray fluorescence imaging system, inspired by a similar system being developed for planetary exploration missions, brings high-resolution elemental mapping directly into the galleries in an accessible way. Continue reading From Mars to the museum: The application of full-field X-ray fluorescence (XRF) to the study of a Caillebotte painting
