Uncovering Art History Through Spectroscopy
Researchers at Delft University of Technology (The Netherlands) and the University of Antwerp (Antwerp, Belgium) used synchrotron radiation-induced X-ray fluorescence spectroscopy to reveal a portrait of a woman by Vincent van Gogh beneath the paint of his 1887 "Patch of Grass."
Researchers at Delft University of Technology (The Netherlands) and the University of Antwerp (Antwerp, Belgium) used synchrotron radiation-induced X-ray fluorescence spectroscopy to reveal a portrait of a woman by Vincent van Gogh beneath the paint of his 1887 "Patch of Grass." Van Gogh was known to paint over his work, perhaps as often as one third of the time. Behind the painting, done mostly in greens and blues, is a portrait of a woman, rendered in browns and reds. Synchrotron radiation-induced X-ray fluorescence spectroscopy measures chemicals in the pigments, and is said to be an improvement on X-ray radiography, which has been used to reveal concealed layers of other famous paintings. In this case, mercury and antimony were useful in revealing the woman?s face. Researchers said that the new technique is expected to pave the way for research into many other concealed paintings.
AI, Deep Learning, and Machine Learning in the Dynamic World of Spectroscopy
December 2nd 2024Over the past two years Spectroscopy Magazine has increased our coverage of artificial intelligence (AI), deep learning (DL), and machine learning (ML) and the mathematical approaches relevant to the AI topic. In this article we summarize AI coverage and provide the reference links for a series of selected articles specifically examining these subjects. The resources highlighted in this overview article include those from the Analytically Speaking podcasts, the Chemometrics in Spectroscopy column, and various feature articles and news stories published in Spectroscopy. Here, we provide active links to each of the full articles or podcasts resident on the Spectroscopy website.
