Fourier transform infrared spectroscopy; X-radiation; analytical chemistry; coatings; image analysis; oxidation; risk; silver chloride; solubilization; stratigraphy
Abstract:
... For more than a century, the analyses of painting fragments have been carried out mainly through the preparation of thick resin-embedded cross-sections. Taking into account the development of innovative micro-analytical imaging techniques, alternatives to this standard preparation method are considered. Consequently, dedicated efforts are required to develop preparation protocols limiting the risk ...

Subject:
Fourier transform infrared spectroscopy; X-radiation; X-ray diffraction; cation exchange capacity; chemical bonding; crystal structure; fly ash; hot water treatment; sodium hydroxide; zeolites
Abstract:
... The interaction of the fly ash and NaOH, in an open reflux hydrothermal system at 100°C, has been explored by several researchers and formation of fly ash zeolites has been confirmed based on the X-ray diffraction analysis of the residues. However, this method does not reveal much about the characteristic transitions (viz. elemental, electro-negativity and cation exchange capacity) of the residues ...

Abstract:
... Recent studies have shown that modern pigments produced after the Second Industrial Revolution are complex systems characterized by a high level of heterogeneities. Therefore, it is fundamental to adopt a multianalytical approach and highly sensitive methods to characterize the impurities present within pigments. In this work we propose time-resolved and spectrally resolved photoluminescence (PL) ...
