Special Issue Information

Dear Colleagues,

Nanomaterials and nanotechnologies have reshaped heritage science thanks to their unique properties and advantages. This Special Issue intends to bring together scientists, engineers, data specialists, art historians, archaeologists, conservators, and restorers to deliver reliable and durable outcomes for the protection of our shared past. We welcome contributions that integrate advanced diagnostics to assess vulnerabilities and cutting-edge nano-enabled materials to address them.

Today, nano-informed approaches are widely used to study, maintain, and consolidate artefacts, works of art, objects, monuments, and other types of heritage of artistic, historical, and anthropological value. We seek original work that advances this practice with focuses including, but not limited to, in situ/portable methods (e.g., XRF/XRD, hyperspectral/thermal imaging, fibre-optic reflectance, etc.), nanoscale and correlative characterisation (including AFM, OCT, electron microscopy, synchrotron- and neutron-based techniques, X-ray spectroscopy), and nano-enabled treatments (consolidants, protective coatings, cleaning/desalination systems). Submissions that document compatibility, reversibility, durability/ageing, and environmentally sustainable solutions, including case histories and field trials, are also encouraged.

By highlighting standards, protocols, inter-laboratory comparisons, and open/FAIR data, this Special Issue also aims to consolidate best practices and accelerate responsible adoption of nano-based diagnostics, conservation, and restoration in heritage science.

We warmly invite scientists and academic/professional conservators and restorers to submit original research, methods/protocols, reviews, short communications, or case studies to “Nanomaterials, Nanotechnologies, and Nano-Characterisation in Heritage Science: From Diagnostics to Conservation and Restoration.” Contributions demonstrating multidisciplinary collaboration and real-world impact are particularly welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Consolidation treatments are essential for the conservation of wall paintings affected by decohesion and disintegration phenomena. In hypogean environments, high relative humidity, limited ventilation and elevated biological risk impose particularly stringent performance requirements. Under these conditions, consolidants must ensure chemical compatibility, effective distribution within water-saturated substrates, long-term stability at high relative humidity and low toxicological impact. Calcium-based nanomaterials, especially nanolime dispersions, are widely employed as reference consolidants. However, their performance is strongly influenced by the dispersing medium, environmental conditions and substrate characteristics. This study addresses the lack of comparative assessments of currently available calcium-based consolidants by testing four products—two alcohol-based nanolimes (Nanorestore Plus® and CaLoSil®), one aqueous nanolime dispersion (Nanolaq®) and a laboratory-formulated aqueous nanocalcite—applied to painted mock-ups. For the first time, the effectiveness of these treatments was investigated under both high relative humidity and water-saturated conditions through a multi-analytical approach. Colorimetric variations, water vapour permeability, water absorption and consolidant distribution within the pictorial layers were evaluated. The results provide a comparative assessment of consolidant performance as a function of the hygrometric regime of the substrate, with differentiated responses under high-humidity conditions and attenuated differences under water-saturated conditions. Overall, the effectiveness of the consolidant appeared to depend significantly on the combined influence of the dispersing medium, the imbibition state of the substrate and its chemical nature, highlighting the need for selection criteria and evaluation protocols based on simulating realistic conservation conditions.
