Special Issue Information

Dear Colleagues,

We are pleased to inform you about the opportunity to submit a research paper or review article on the latest advances in surface engineering for the creation of new functional nanomaterials to our Special Issue.

One of the important tasks of modern materials science is the development of new composite materials with improved functional properties. Currently, research is being actively carried out related to the development of combined approaches in the synthesis of new-generation composites by structuring them both in bulk and on the surface to improve functional properties (magnetic, mechanical, biomedical, catalytic, etc.). Requirements for the structure and physicochemical properties of composites, including nanomaterials, vary depending on the specific application. Therefore, the role of the surface in controlling the properties of composites cannot be overestimated. By studying the influence of the surface of the reinforcing phase on the structure and properties of the composite, it is possible to achieve a deeper understanding of the processes of formation of metal and ceramic composites and further directionally predict their properties.

It should be noted that the creation of composite materials with a given set of properties remains a difficult task, which necessitates the development of methods for controlling their structure and physicochemical properties both at the stage of synthesis and subsequent post-processing for wide practical applications in various devices. In view of this, surface engineering is one of the key areas for the formation of composite materials with optimized physical and chemical characteristics for each specific application.

This Special Issue will present the latest work on the synthesis and modification of materials, including nanomaterials, to form new composites, from nanostructure to modeling and practical applications. We invite the submission of publications that include, but are not limited to, any of the following subject areas:

  • Creation of a new generation of ceramic and metal composite materials for mechanical engineering
  • Magnetic smart materials for biomedical applications
  • Powders of complex composition and multifunctional application for the production of composite materials.
  • Surface engineering methods to improve the functional properties of composites
  • Synthesis of composite functionally graded nano-coatings, including those for implantology.
  • Synthesis and characterization of nanomaterials for electrochemical applications
  • Modeling the structure and properties of modified nanomaterials
  • Oxygen reduction electrocatalysts

This paper presents the results of a study on the characteristics of semiconductor sensors based on thin SnO2 films modified with antimony, dysprosium, and silver impurities and dispersed double Pt/Pd catalysts deposited on the surface to detect carbon monoxide (CO). An original technology was developed, and ceramic targets were made from powders of Sn-Sb-O, Sn–Sb-Dy–O, and Sn–Sb-Dy-Ag–O systems synthesized by the sol–gel method. Films of complex composition were obtained by RF magnetron sputtering of the corresponding targets, followed by technological annealing at various temperatures. The morphology of the films, the elemental and chemical composition, and the electrical and gas-sensitive properties were studied. Special attention was paid to the effect of the film composition on the stability of sensor parameters during long-term tests under the influence of CO. It was found that different combinations of concentrations of antimony, dysprosium, and silver had a significant effect on the size and distribution of nanocrystallites, the porosity, and the defects of films. The mechanisms of degradation under prolonged exposure to CO were examined. It was established that Pt/Pd/SnO2:0.5 at.% Sb film with optimal crystallite sizes and reduced porosity provided increased stability of carbon monoxide sensor parameters, and the response to the action of 100 ppm carbon monoxide was G1/G0 = 2–2.5.

Cotton fabrics with zinc oxide (ZnO) coating are of significant interest due to their excellent antibacterial performance. Thus, they are widely in demand in the textile industry due to their medical and hygienic properties. However, conventional techniques used to deposit ZnO on fabric require long processing times in deposition, complex and expensive equipment, and multiple steps for deposition, such as a separate process for nanoparticle synthesis and subsequent deposition on fabric. In this study, we proposed a new method for the deposition of ZnO on fabric, using cathodic cage plasma deposition (CCPD), which is commonly used for coating deposition on conductor materials and is not widely used for fabric due to the temperature sensitivity of the fabric. The effect of gas composition, including argon and a hydrogen–argon mixture, on the properties of ZnO deposition is investigated. The deposited samples are characterized by XRD, SEM, EDS, photocatalytic, and antibacterial performance against Staphylococcus aureus and Pseudomonas aeruginosa bacteria. It is observed that ZnO-deposited cotton fabric exhibits excellent photocatalytic degradation of methylene blue and antibacterial performance, specifically when a hydrogen–argon mixture is used in CCPD. The results demonstrate that CCPD can be used effectively for ZnO deposition on cotton fabric; this system is already used in industrial-scale applications and is thus expected to be of significant interest to garment manufacturers and hospitals.

Despite a long period of application of metal implants, carbon–carbon medical composites are also widely used for bone defect prosthesis in surgery, dentistry, and oncology. Such implants might demonstrate excellent mechanical properties, but their biocompatibility and integration efficiency into the host should be improved. As a method of enhancing, the electrophoretic deposition of fine-dispersed hydroxyapatite (HAp) on porous carbon substrates might be recommended. With electron microscopy, energy dispersion X-ray and Raman spectroscopy, and X-ray diffraction, we found that the deposition and subsequent heat post-treatment (up to the temperature of 400 °C for 1 h) did not lead to any significant phase and chemical transformations of raw non-stoichometric HAp. The Ca/P ratio was ≈1.51 in the coatings. Their non-toxicity, cyto- and biocompatibility were confirmed by in vitro and in vivo studies and no adverse reactions and side effects had been detected in the test. The proposed coating and subsequent heat treatment procedures provided improved biological responses in terms of resorption and biocompatibility had been confirmed by histological, magnetic resonance and X-ray tomographic ex vivo studies on the resected implant-containing biopsy samples from the BDF1 mouse model. The obtained results are expected to be useful for modern medical material science and clinical applications. Full article

The general trend of increasing life expectancy will consistently drive the demand for orthopedic prostheses. In addition to the elderly, the younger population is also in urgent need of orthopedic devices, as bone fractures are a relatively common injury type; it is important to treat the patient quickly, painlessly, and eliminate further health complications. In the field of traumatology and orthopedics, metals and their alloys are currently the most commonly used materials. In this context, numerous scientists are engaged in the search for new implant materials and coatings. Among the various coating techniques, plasma electrolytic oxidation (PEO) (or micro-arc oxidation—MAO) occupy a distinct position. This method offers a cost-effective and environmentally friendly approach to modification of metal surfaces. PEO can effectively form porous, corrosion-resistant, and bioactive coatings on light alloys. The porous oxide surface structure welcomes organic molecules that can significantly enhance the corrosion resistance of the implant and improve the biological response of the body. The review considers the most crucial aspects of new combined PEO-organic coatings on metal implants, in terms of their potential for implantation, corrosion resistance, and biological activity in vitro and in vivo.
