Special Issue Information

Dear Colleagues,

Metal ions are ubiquitously present in nature and play critical roles in numerous physical, chemical, and biological processes. Their unique characteristics, particularly their positive charge, confer distinctive chemical reactivity and coordination properties. These properties enable metal ions to participate in a wide range of interactions, making them indispensable in various fields such as environmental remediation, catalysis, energy conversion, biomedical applications, nanotechnology, materials science, agriculture, optics, and electronics.

The study of metal ions and their interactions is vital for advancing our understanding of the underlying mechanisms that govern catalytic, environmental, and biological processes. The ability to manipulate metal ion behavior has led to innovations in multiple disciplines, driving scientific progress in areas ranging from efficient energy storage/conversion to the development of advanced materials and therapeutic agents. The diverse and versatile nature of metal ions continues to inspire significant research efforts, bridging fundamental science and applied technology.

This Special Issue aims to explore the diverse roles and applications of metal ions across various scientific and technological domains. We seek to highlight cutting-edge research that enhances our understanding of the chemical, physical, and biological behaviors of metal ions, with a particular focus on their interactions with other molecules, materials, and environments. This collection of articles will contribute to advancing our knowledge in key areas such as catalysis, environmental protection, biomedical applications, and nanotechnology.

In this Special Issue, original research articles and reviews are welcome to be submitted. Research areas may include, but are not limited to, the following:

  • Metal ion-based materials for energy storage (e.g., batteries, supercapacitors);
  • Biological and biomedical applications of metal ions (e.g., drug delivery, imaging agents, enzyme mimicry);
  • Metal ions in environmental remediation and pollution control (e.g., water treatment, desalination, CO2 capture);
  • Metal ions in catalytic processes and energy conversion (e.g., electrochemical reactions, fuel cells, hydrogenation);
  • Metal ion interactions with nanomaterials for sensing and diagnostics;
  • Development of novel methods for metal ion detection and characterization;
  • Advances in the synthesis and characterization of metal ion-based nanomaterials;
  • Computational modeling of metal ion behavior in materials and biological systems;
  • Coordination chemistry and molecular interactions of metal ions in complex systems;
  • Advances in the understanding of metal ion interactions in materials science and electronics.

We look forward to receiving your contributions and to collaborating on this exciting exploration of the diverse roles of metal ions in modern science and technology.

Kraft paper, commonly known as brown paper, has been widely used in the preservation of various food products and is increasingly explored in the development of active packaging materials with antimicrobial functionality by incorporating metal nanoparticles. This study aimed to comparatively investigate the surface modification of Kraft paper with silver nanoparticles (AgNPs) using dip-coating and drop-casting techniques. AgNPs were produced via green synthesis and incorporated onto the surface of Kraft paper samples. The modified samples were characterized using physicochemical techniques, including atomic force microscopy (AFM), Raman spectroscopy and light microscopy, as well as nanomechanical characterization via force spectroscopy. The antimicrobial activity of the modified papers was assessed using the disk diffusion method. The results demonstrated that the modification techniques resulted in distinct surface characteristics. Samples treated with the drop-casting method exhibited the highest AgNP surface loading; however, this was accompanied by pronounced surface heterogeneity and a tendency toward reduced load-bearing capacity. Overall, the findings indicate that the choice of deposition technique plays a key role in controlling nanoparticle distribution and surface properties. Within the limitations of the techniques evaluated, the incorporation of nanomaterials with potential antimicrobial activity into Kraft paper may offer opportunities for the development of active food packaging, although further optimization is required.
