Special Issue Information

Dear Colleagues,

Synthesis methods and characteristics in nanostructured materials (such as size, crystal structure, surface morphology, porosity, grain boundaries, shape, and composition) represent an active area of research, opening up new opportunities, with a wide range of applications in chemistry, physics, ceramics, biology, engineering, medicine, and the environment. Structured nanomaterials can be obtained through a variety of methods, including combustion; coprecipitation; pyrolysis; solid-state techniques; the sol–gel process; spray drying; microemulsion; sonochemical, hydrothermal, microwave, and solvothermal synthesis; thermal decomposition; and biosynthesis. A particular focus will be placed on contributions that show an interdisciplinary perspective, combining various properties that allow for the development of advanced dielectric, photoluminescent, thermal, magnetic, catalytic, photocatalytic, coloristic, corrosion protection, sensor, water decontamination, antimicrobial, and biomedical applications.

This Special Issue aims to provide a comprehensive overview of this area of study, including original research articles, comprehensive reviews, or new communications that focus on the synthesis, preparation, characterization, modeling, and applications of structured nanomaterials. Potential topics include, but are not limited to, the following:

  • Different synthesis routes and characteristics in nanofibers, nanoparticles, nanowires, nanotubes, or biodegradable polymers;
  • Nanostructures (hydrogels, graphene, clays, etc.), coatings, and thin films;
  • Correlations between the thermal stability (TG, DTA, or DSC), chemical composition, structural (XRD, FT-IR, Mossbauer, or XPS), morphology (TEM, SEM, or AFM), and surfaces (BET or porosity) of nanostructured materials;
  • Magnetic, optical, or electrical applications for nanostructured materials;
  • Thermal stability of nanostructured drugs and proteins;
  • Innovative ceramic pigments for the coloration of ceramic glazes;
  • Nanostructured materials with applications in catalysis, autocatalysis, biocatalysis, photocatalysis, or electrocatalysis;
  • Adsorption/removal of organic and inorganic pollutants (heavy metals, dyes, pesticides, and other pollutants) through nanostructured materials for water purification;
  • Computation and algorithms for reaction mechanisms, kinetics, and thermodynamics;
  • Theoretical simulation and interpretation of advanced nanomaterials and interfaces;
  • Materials for high-performance rechargeable batteries;
  • Antimicrobial, antibacterial, and anticancer activity and biomedical applications;
  • Nanomaterials for biosensing, such as optical sensors, electrochemical sensors, or colorimetric strips.

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 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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Materials engineering has become an important tool in the field of hydrogel dressings used to treat difficult-to-heal wounds. Hydrogels filled with bioactive substances used as a targeted healing system are worthy of attention. Vitamin C has healing and supporting effects in the treatment of many skin problems. The aim of the research was to produce a hydrogel biomaterial enriched with ascorbic acid for use as a dressing for difficult-to-heal wounds. A total of four different dressings were developed, each with different modifications in each layer. The dressing with vitamin C in the third layer was shown to release vitamin C ions more slowly than the dressing with vitamin C in the first layer. The studies conducted have shown that the dressings containing vitamin C have, among other things, a higher compressive strength, are characterised by a lower relative shortening after the application of force and shorten without damage at a lower force than in the case of a dressing without vitamin C. The dressings designed have a very good stability in the temperature range of 18 °C to 60 °C. It was found that the higher the vitamin C content in the dressing, the greater the increase in the specific heat value of the transformations. Therefore, hydrogel dressings containing vitamin C may be candidates for local delivery of vitamin C to the skin and protection of the wound area. Full article
