Special Issue Information

Dear Colleagues,

Nanomaterials and nanotechnologies in the last few decades have generated an increased interest in the cultural heritage community due to their unique characteristics and advantages. The synergy of a multidisciplinary approach from different areas of knowledge and the dialogue with conservators and restorers is a key factor for achieving reliable and durable results in the protection of our historical past, with the development and use of advanced diagnostic techniques to assess criticalities and cutting-edge materials for solving these issues.

Today, there is a widespread use of such nanomaterials and the application of nanotechnologies or characterization techniques at the nanoscale to study, maintain, and consolidate artifacts, works of art, objects, monuments and intangible attributes that convey artistic, historical, or anthropological values.

The objective of this Special Issue is to collect contributions on the latest advances in research to increase and safeguard cultural heritage. The Special Issue is dedicated to the publication of original work from scientists and academic and professional conservators and restorers who are involved in the conservation, restoration, and consolidation of cultural heritage, highlighting the use of nanomaterials and nanotechnology in case studies and applying lab-scale available techniques, advanced methods from neutron sources and  X-ray spectroscopy; using, among others, in-situ techniques, environmental sustainable solutions and contributions from case histories. We hereby invite and encourage all experts in these multidisciplinary fields to submit their contributions.

To acknowledge your important contribution in these fields, we would like to warmly invite you to submit a manuscript for consideration in the “Nanotechnologies for Diagnostic, Conservation, and Restoration of Cultural Heritage” Special Issue.

New Perspectives for the Consolidation of Mural Paintings in Hypogea with an Innovative Aqueous Nanolime Dispersion, Characterized by Compatible, Sustainable, and Eco-Friendly Features

Consolidation of mural paintings in hypogea is challenging because of their severe microclimatic conditions, characterized by high humidity levels, low air circulation, the presence of salts efflorescence, and the detrimental growth of biodeteriogen agents. Traditional consolidant products show significant drawbacks when used in hypogeum. Organic compounds, such as acrylic emulsions, are bio-receptive and some inorganic consolidants, such as silica-based products, show a lack of compatibility with the original substrate, which could lead to a reduction in permeability and an increase in the mechanical resistance of the external layer. The presence of solvents in their formulations, particularly short-chain alcohols that can activate germination of fungal spores, leads to the release of great amounts of volatile organic compounds, which are particularly harmful in the hypogeic environment. To solve these problems, restorers of the Istituto Centrale per il Restauro (ICR) decided to use a new aqueous nanolime dispersion, NANOLAQ, consisting of pure and crystalline Ca(OH)2 nanoparticles dispersed in water, produced by an innovative and sustainable patented procedure. After laboratory testing, the product has been applied on site, on a medieval mural painting in the Ss. Peter and Paul hypogeum in the UNESCO site of Matera (Italy), monitoring the performance in terms of cohesion of the paint layer and preservation of aesthetic features. Full article

This research has focused on the assessment of the compositional features and mechanical and antifouling performances of two different mortars formulated for an underwater setting, and which contain Mg(OH)2 as an antifouling agent. Regarding the mechanical characterization, the uniaxial compressive strength and flexural strength were measured. The composition of the materials was explored by differential thermal/thermogravimetric analysis (DTA-TG), X-ray diffraction analysis (XRPD), and scanning electronic microscopy (SEM) coupled with EDS microanalysis. The assessment of the biological colonization was evaluated with colorimetric analysis and image analysis. The results suggest that both mortars have good mechanical resistance once set underwater. Moreover, the adding of Mg(OH)2 improves the resistance toward biofouling; this was observed both in laboratory and sea-exposed specimens. Full article

An experimental nano-filled coating, based on a fluorine resin containing SiO2 nano-particles, was applied on calcareous stones, representative of materials used in buildings and monuments of the Mediterranean basin; for comparison purposes, two commercial products were applied on the same substrates. The efficacy of the protective treatments was assessed by analyzing different characteristics of the three experimental/commercial products, i.e., color changes and permeability to water vapor to evaluate the treatments’ harmlessness; capillary water absorption and water stone contact angle to evaluate the protection against water ingress; oleophobicity of the treated surfaces and the behavior under staining by acrylic blue-colored spray paint and felt-tip marker to verify the anti-graffiti action. Finally, the properties of the treated stone surfaces were analyzed also after the application of pancreatin, used to simulate bird excreta (guano). The protective coatings were found to promote graffiti removal, reducing also the detrimental effects due to simulated guano. The experimental nano-filled product, in addition, was able to provide outstanding performance but using smaller amounts of product in comparison to commercial systems. Full article
