Special Issue Information

Dear Colleagues,

The scope of this Special Issue is to provide a platform to the researchers from both the academy and industry to share their state-of-the-art developments in the very fast-growing field of nanomaterials. I would like to invite papers on the processing, characterization, and testing of nanoparticles and nano-structured or nanocomposite coatings. The contributed papers can be original research articles, letters, and reviews of the latest research dealing with both fundamental aspects and industrial or technological applications. The purpose is to address the recent developments in nanoparticles design, synthesis, and characterization, highlighting their emerging or potential technological applications in industrial fields, such as medical, renewable energy, oil and gas, electronic, aerospace, and automotive, industries.

Topics of interest include but are not limited to the following:

  • Synthesis of nanoparticles and/or nanostructured coatings;
  • Nanocomposite coatings;
  • Characterization of structure, chemical compositions, surface, and interface properties;
  • Mechanical testing;
  • Biocompatibility;
  • Thermal stability and corrosion behavior;
  • Wear and friction;
  • Characterization techniques;
  • Performance in industrial or extreme environmentrs, e.g., corrosion protection in harsh environments, mechanical properties at elevated or very low temperatures;
  • Cultural heritage and environmental applications;
  • Catalysis and novel applications.

Abstract
The long-term chloride resistance of concrete treated with nano-TiO2-modified polymer coatings was studied. Three types of organic film-forming paints: polyurethane, epoxy resin, and chlorinated rubber were selected, and concrete specimens with nano-TiO2-modified coatings were fabricated. Then, specimens were subjected [...] Read more.
The long-term chloride resistance of concrete treated with nano-TiO2-modified polymer coatings was studied. Three types of organic film-forming paints: polyurethane, epoxy resin, and chlorinated rubber were selected, and concrete specimens with nano-TiO2-modified coatings were fabricated. Then, specimens were subjected to periodical ultraviolet-accelerated aging and subsequent Coulomb electric flux experiments. Nanomodified coatings before and after ultraviolet aging were observed through scanning electron microcopy. Results indicate that the nano-TiO2 particles can effectively reduce the microdefects in coating films and alleviate damages due to aging. As a result, nano-TiO2 can significantly reduce the Coulomb fluxes of coated concrete before and after coating aging, and the average reduction amplitudes reached 66% and 44%. That is, nano-TiO2 can remarkably improve the long-term chloride resistance of coated concrete. In addition, we established the development models of the ultraviolet aging and chloride resistance of coated concrete according to an S-shaped curve. Full article

Sol-gel based gallium-doped ZrO2 coatings for infection prevention of implantable devices

Abstract: Infections represent a major clinical problem in implantable devices, often resulting in morbidity, implant failure, and severe complications. The design of antibacterial nanostructured surfaces is actively pursued as an effective strategy to decrease implant related infections at tissue interface. Metal ions have been exploited as a suitable tool to prevent bacterial adhesion and colonization on surfaces: among those, Ga3+ shows unique properties, both combining antibacterial capability and excellent biocompatibility. In this work, Sol-gel synthesis will be presented as an easy yet effective technology to functionalize devices with thin zirconium oxide films doped with Ga3+ ions. The coatings obtained through this approach are stable, biocompatible, and show a significant antibacterial activity, suggesting a promising potential in dental and orthopaedic applications.
