“…PVA has also been adopted in gel formulations where the polymer is crosslinked with telechelic PVA (tel-PVA, i.e., PVA with an aldehyde at each chain end). The ratio between the two components can be adjusted to tune the porosity/ retentiveness and mechanical properties of the gels, which have proven optimal tools for cleaning photographs and paper items [123][124][125].…”

Cultural heritage assets constitute a fundamental socioeconomic resource, but the actual works of art need to be maintained, counteracting degradation processes, to transfer these benefits to future generations. In particular, the removal of soil, aged coatings, and vandalism/overpaints is one of the most needed interventions in art restoration. Traditional cleaning methodologies, based on classical solution and polymer chemistry, only grant limited control of the cleaning interventions, with the risk of affecting the original components of the artifacts, and often involving the use of toxic or non-environmentally friendly compounds. Alternatively, materials science, colloids, and soft matter have provided valuable and safe solutions in the last decades. This review provides a selection of the most recent and advanced methodologies for the wet cleaning of works of art, spanning from nanostructured cleaning fluids (microemulsions, surfactants swollen micelles) to physical and chemical gels. The new methodologies work on different physico-chemical mechanisms, such as processes for detaching/dewetting, to selectively remove the unwanted layers in sustainable and cost-effective interventions. The best performing systems, like microemulsions confined in “twin-chain” polyvinyl alcohol gels, have been assessed in the cleaning of masterpieces such as works by Pablo Picasso, Jackson Pollock and Roy Lichtenstein. Particular attention is dedicated to “green” chemistry systems, using low-toxicity solvents or bio-based/waste materials to build gel networks. Finally, current trends and future perspectives are given, showing that advanced systems for art cleaning link with transversal fields of crucial importance even beyond Cultural heritage conservation, e.g., detergency, tissue engineering, drug-delivery, food industry and cosmetics.

Raffaello is renowned as one of the Old Renaissance Masters and his paintings and painting technique are famous for the details and naturality of the characters. Raffaello is famous in particular for the then-new technique of oil painting, which he mastered and perfected. On the occasion of the 500th anniversary of the death of Raffaello (2020), there was a large exhibition at the Scuderie del Quirinale in Rome, where many paintings and drawings by the Old Master were on show. One of these paintings was the portrait of Leo X with two cardinals belonging to the collection of the Uffizi galleries in Florence. Before going to Rome, the painting underwent conservation treatments at the Opificio delle Pietre Dure, where a comprehensive diagnostic campaign was carried out with the aim of understanding the painting materials and technique of the Old Master. In this paper, the results of macro X-ray fluorescence (MA-XRF) analysis, carried out exploiting the instrument developed by INFN-CHNet, are shown. Among the results, “bismuth black” and the likely use of glass powders in lakes are discussed.

The mission of the Cultural Heritage Network of the Italian Institute of Nuclear Physics (INFN-CHNet) is presented here through a “virtuous” example: the activity related to the Macro-X-Ray Fluorescence (MA-XRF) scanner. The main focus of INFN-CHNet is the collaboration and sharing of knowledge among the network members, to better address the issues of Cultural Heritage operators, while the fields of activity are research (instrumental development and data management), analysis of cultural objects, education of young scholars and professionals, and dissemination to the general public. In this context, the MA-XRF scanner exemplifies the objectives of INFN-CHNet, being the first instrument developed, tested and optimised jointly by several INFN-CHNet partners. It was designed to be an open (free access to information on processes, components and materials), low-cost system, based on sustainability and interoperability, and modular. All these features allow for easy replication of instruments in any node of the network or reuse of system/subsystem also in different projects. Moreover, for the MA-XRF scanner, the whole path from data acquisition to their storage, management and visualisation/reuse has been addressed. The activities related to the scanner clearly demonstrate the effectiveness of the approach of CHNet in all the issues that arise in conservation and study of CH.
