Special Issue Information

Dear Colleagues,

New materials have been among the greatest achievements of every decade, because they are essential to the growth, prosperity, security, and quality of life of humans and cultural heritage since the beginning of history. New materials always initiate new technologies, whether they be in civil, chemical, construction, nuclear, aeronautical, agricultural, mechanical, biomedical, art and culture or electrical engineering.

Cultural Heritage (CH), both tangible and intangible, natural and manmade, or movable and immovable, connects us to future generations—explaining the current trend toward further studies and research to better understand the dynamic relationship between heritage conservation and the various materials and development of nondestructive testing in engineering.

This Special Issue is open to new advances in nondestructive testing of materials surface in different areas, including:

  • Chemical composition of the materials surface/interface: thin layers)
    - Nature of the elements : SEM-EDS, XRF, XPS-ESCA, ToF-SIMS, TEM-EDS;
    - Elementary chemical analysis to identify compounds, or X-Ray diffraction;
  • Molecular analysis : ToF-SIMS, FTIR, RAMAN
    - Low concentrations detection : ToF-SIMS, XRF;
    - Concentration (profiles (nm–µm)): XPS, SEM-EDS, GC-MS, GC/MS/MS, HPLC/MS/MS;
    - Chemical state of the elements: chemical bonding, functional groups, oxidation state: ToF-SIMS, XPS, FTIR, RAMAN;
  • Position of the elements (or locating the elements):
    - Lateral: chemical mapping: SEM EDS, ToF-SIMS, XPS, RAMAN, TEM-EDS
    - In depth profiles: XPS, ToF-SIMS, EDS on the edge

These methods are useful for material characterization, and surface analysis can be used to assess weathering and deterioration effects on stone monuments and buildings of cultural heritage, detect defects invisible on the surface, estimate the depth of cracks, as well as for the characterization and structure of materials, corrosion, coating, and protection of materials and implications of nanomaterials in restoration technology.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials 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 2600 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

In the last few years, the preservation of cultural heritage has become an important issue globally, due to the fact that artifacts and monuments are continually threatened by degradation. It is thus very important to find adequate consolidators that are capable of saving and maintaining the natural aspect of these objects. This study aims to provide an updated survey of the main nanomaterials used for the conservation and restoration of cultural heritage. In the last few years, besides the classic nanomaterials used in this field, such as metal nanoparticles (copper and silver) and metal oxides (zinc and aluminum), hydroxyapatite and carbonated derivatives, tubular nanomaterials (such as carbon nanotubes) have been used as a potential consolidate material of cultural heritage. Tubular nanomaterials have attracted attention for use in different fields due to their structures, as well as their ability to present multiple walls. These nanotubes have the necessary properties in preserving cultural heritage, such as superior mechanical and elastic strength (even higher than steel), high hydrophobicity (with a contact angle up to 140°), optical properties (high photodegradation protection), large specific surface area (from 50 to 1315 m2/g, depending on the number of walls) for absorption of other nanomaterials and relatively good biocompatibility.
