Novel Comparative Efficiency of Ozone and Gamma Sterilization on Fungal Deterioration of Archeological Painted Coffin, Saqqara Excavation, Egypt

A Comprehensive and Systematic Diagnostic Campaign for a New Acquisition of Contemporary Art—The Case of Natura Morta by Andreina Rosa (1924–2019) at the International Gallery of Modern Art Ca’ Pesaro, Venice

“…When the spectra obtained for the front of the artwork were considered, signals from the grounding could still be recognized, particularly where the painted layer was fairly thin (Figure 9b). Spectra obtained with ER-FTIR further confirmed the hypothesized composition of the grounding, as characteristic features for gypsum [41,[46][47][48][49][50], calcite [46,51,52], lithopone [47,48,53,54], and for the proteinaceous glue [49,[55][56][57] were registered (Figure 10b). Zinc oxide was also detected [53].…”

Non-Destructive Analytical Investigation of Decorative Wallpapers Samples of the Nineteenth Century before Their Restoration

“…Indeed, the band at 1642 cm −1 corresponds to a fundamental stretching of the amide carbonyl group (–CO–NH–, 1655 cm −1 ) and the deformation of amide II (–NH 2 , 1632 cm −1 ) [ 30 ]. In the FTIR spectrum methylene group, absorbencies at 2853 and 2923 cm −1 were also evident, and the broad band centered at about 3300 cm −1 (N-H stretching), indicating hydroxyl and amide groups partially masked by the broad absorption band of the OH group [ 31 ]. The evidence in the ATR-FTIR spectrum was compatible with the presence of animal glue.…”

An Analytical Investigation and a Mycological Study of Some Architectural Stucco Monuments in the Period of Mamluk and Ottoman Rule of the Islamic Era, Egypt.

“…An analysis is fundamental to identify the products of the stucco components deterioration, including the experimental and all conservation processes (Afifi et al, 2021;Geweely & Afifi 2011;Geweely et al, 2014). Stucco samples were analyzed using Environmental SEM with an Energy Dispersive X-Ray (EDX) unit.…”
