Special Issue Information

Dear Colleagues,

This Special Issue invites original research articles and comprehensive reviews focusing on the synthesis, properties, characterization, and applications of nanoparticles, fibers, and coatings.

A coating is a material layer applied to the surface of a substrate, either covering it entirely or selectively protecting specific regions. Nanoparticles, typically ranging from 1 to 100 nm, exhibit unique physicochemical properties due to their size, shape, and structure. Fibers, generally categorized at the micro- and macro-scale, also demonstrate distinctive mechanical and functional characteristics. The reactivity, toughness, and performance of nanoparticles, fibers, and coatings are strongly influenced by their structural features, making them highly attractive for a wide range of applications.

Owing to these properties, nanoparticles, fibers, and coatings have found extensive use in catalysis, medical and biomedical technologies, energy-related research, imaging, and environmental applications, among others.

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

  • Synthesis and fabrication methods;
  • Structural determination using diffraction techniques;
  • Spectroscopic characterization methods (e.g., IR, NMR, Raman, UV–Vis, CD);
  • Characterization of physical and chemical properties, including catalytic activity, electrical conductivity, magnetic behavior, luminescence, and porosity;
  • Application of theoretical and computational methods for determining structures and properties;
  • Applications of nanoparticles, fibers, and coatings in green and sustainable energy technologies;
  • Emerging and advanced applications of nanoparticles, fibers, and coatings across various fields.

The development of sustainable electrocatalysts for clean energy by modifying biomass-derived activated carbon with nitrogen and transition metals is presented. Activated carbon (AWC) material was obtained using alder wood char as a precursor, while nitrogen and cobalt or copper nanoparticles were incorporated with the aim of creating efficient materials for hydrazine oxidation (HzOR) and direct hydrazine–hydrogen peroxide fuel cells (DHHPFC, N2H4–H2O2). The composition, structure, and surface morphology of the created materials were examined using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), and inductively coupled plasma optical emission spectroscopy (ICP-OES). The activity of the AWC, AWC–Co–N, and AWC–Cu–N catalysts for HzOR was investigated using cyclic voltammetry (CV) and linear sweep voltammetry (LSV). N2H4–H2O2 fuel-cell tests were performed by applying the catalysts as both the anode and cathode. It was found that all materials retained a hierarchical porous carbon framework, while metal incorporation altered surface compactness. Cobalt doping produced well-dispersed Co nanoparticles and abundant Co–N–C coordination sites, whereas Cu introduction resulted in moderately compact structures with uniformly distributed Cu-based nanoparticles. Electrochemical measurements demonstrated that both metal dopants enhanced HzOR activity, with the catalytic performance following the order of AWC–Co–N > AWC–Cu–N > AWC. Fuel-cell testing further confirmed this trend: AWC–Co–N achieved the highest maximum power density (30.4 mW cm−2), outperforming AWC–Cu–N (17.7 mW cm−2). These results identify AWC–Co–N as a highly effective bifunctional electrocatalyst for DHHPFCs. Full article
