A spatially resolved study by µ-XRF and µ-XANES spectroscopy at S K-, Cu K- and As K-edges to understand the degradation process of copper arsenic-based oil paints

This repository contains the raw X-ray Fluorescence (XRF) and X-ray Absorption Near-Edge Structure (XANES) datasets obtained at the Copper (Cu) K-edge during the HG-199 experiment, conducted at the ID21 beamline. These data constitute a critical component of the scientific findings detailed in the accompanying Science Advances article, titled: "Discovering the Dual Degradation Pathway of Emerald Green in Oil Paints: the Effects of Light and Humidity" (DOI provided below). Please contact the authors should any additional details or context be required.
