Evidence for Degradation of the Chrome Yellows in Van Gogh’s Sunflowers: A Study Using Noninvasive In Situ Methods and Synchrotron‐Radiation‐Based X‐ray Techniques
20-Oct-2015 | Letizia Monico, Koen Janssens, Ella Hendriks, Frederik Vanmeert, Geert Van der Snickt, Marine Cotte, Gerald Falkenbe ..., Angewandte Chemie International Edition, 2015
Abstract This paper presents firm evidence for the chemical alteration of chrome yellow pigments in Van Gogh’s Sunflowers (Van Gogh Museum, Amsterdam). Noninvasive in situ spectroscopic analysis at several spots on the painting, combined with synchrotron‐radiation‐based X‐ray investigations of ...
Phototransformation of 3-alkoxychromenones: Regioselective photocyclisation and Dealkoxylation
14-Oct-2015 | Ramesh Kamboj; Radhika Khanna; Aarti Dalal; ramesh Kumar, Photochemical & Photobiological Sciences, 2015
Phototransformation of some 2-(3-methoxyphenyl)-4H-chrome-4-ones bearing propynyloxy moiety at 3-position has been described. These chromenones on photolysis by the pyrex filtered UV-light from Hg-lamp (125W) produced a major amount of 5-ethynyl-2-methoxy-6-oxa-benzo[5,6-c]xanthen-7-ones ...
A combined analytical approach applied to Medieval wall paintings from Puglia (Italy): The study of painting techniques and its conservation state
08-Oct-2015 | Daniela Fico, Antonio Pennetta, Giulia Rella, Antonella Savino, Valentina Terlizzi, Giuseppe Egidio De Benedetto, Journal of Raman Spectroscopy, 2015
A combined analytical approach has been applied to the wall paintings, dated from 10th to 14th centuries, of the Santi Stefani crypt at Vaste (Lecce, Southern Italy). These paintings are a precious testimony of Medieval art in Southern Italy. However, the church shows problems of damp as well as ...
Non‐destructive identification of pigments printed on six Imperial China Engraved Coiling Dragon stamps
08-Oct-2015 | Wen‐hua Zhou, Qing Gan, Jin‐xin Ji, Na Yao, Ji‐gang Wang, Zhong Zhou, Xiao‐kun Qi, Ji‐long Shi, Journal of Raman Spectroscopy, 2015
Raman spectroscopy was employed to investigate six Imperial China Engraved Coiling Dragon stamps non‐destructively. The results have shown that (1) the main colors (yellow, green, scarlet, brown, vermilion, and blue) on the six stamps were all prepared from inorganic pigments, including chrome ...

Publication date: January 2016 Source:Microchemical Journal, Volume 124 Author(s): Letizia Monico, Koen Janssens, Marine Cotte, Lorenzo Sorace, Frederik Vanmeert, Brunetto Giovanni Brunetti, Costanza Miliani Environmental factors, such as light, humidity and temperature are ...
Corrosion and biological behavior of nanostructured 316L stainless steel processed by severe plastic deformation
16-Sep-2015 | K. Hajizadeh, H. Maleki‐Ghaleh, A. Arabi, Y. Behnamian, E. Aghaie, A. Farrokhi, M. G. Hosseini, M. H. Fathi, Surface and Interface Analysis, 2015
Nanostructured metals have different mechanical, chemical, and physical behaviors in comparison with the microstructured ones. Numerous research studies demonstrated that the biological behavior of nanostructured metallic implants was improved significantly. Concerning the nanostructured metals, ...

Multi‐analytical non‐invasive study of modern yellow paints from postwar Italian paintings from the International Gallery of Modern Art Cà Pesaro, Venice
18-May-2015 | Francesca Caterina Izzo, Valentina Capogrosso, Michele Gironda, Roberto Alberti, Chiara Mazzei, Luca Nodari, Arianna ..., X-Ray Spectrometry, 2015
We present a multi‐analytical non‐invasive approach for the characterisation of yellow paints used in three paintings from the International Gallery of Modern Art Cà Pesaro, Venice. The paintings selected for this study were executed in oil‐based media between 1940 and 1960, they are unvarnished ...
