Topic: Advanced Nanomaterials: Synthesis, Characterization, and Applications

This Special Issue (SI) highlights recent progress in the design, synthesis, and application of advanced functional nanomaterials produced through diverse chemical routes, including wet-chemistry approaches, gas-phase methods, and solid-state reactions. Advanced functional materials are widely recognized for their exceptional physical and chemical properties that surpass the limitations of traditional materials, and nanostructuring further enhances their tunability, efficiency, and application potential. By gathering contributions from leading research groups worldwide, this Special Issue aims to showcase innovative strategies for controlling composition, morphology, and hierarchical structure across multiple synthesis platforms.

Wet-chemistry routes (such as sol-gel processing, hydrothermal synthesis, precipitation, and colloidal methods) enable precise control over particle size, surface chemistry, and dispersibility, making them ideal for producing nanomaterials for catalysis, energy production and storage, and biomedical applications. Gas-phase techniques, including chemical vapor deposition, atomic layer deposition, and aerosol-based synthesis, provide pathways to highly pure, uniform, and scalable nanostructures with exceptional optical, electronic, and magnetic properties. Solid-state reactions, long valued for their simplicity and robustness, continue to advance through mechanochemical activation, high-temperature diffusion strategies, and modern sintering technologies, enabling the fabrication of complex functional composites and high-performance materials for industrial use. Additionally, high-energy synthesis methods (such as reactive laser ablation in liquids, electrical wire explosion, and self-propagating high-temperature synthesis) make it possible to obtain unique materials, including metastable or otherwise inaccessible phases that cannot be produced by conventional approaches.

Reflecting the broad impact of functional nanomaterials across fields such as energy, catalysis, electronics, medicine, biosensing, and environmental technologies, this SI welcomes original full research articles, short communications, and comprehensive reviews addressing recent advances in preparation, synthesis mechanisms, structural design, characterization, and emerging applications of chemically synthesized nanomaterials. By bringing together diverse chemical methodologies and application-driven research, this collection aims to accelerate innovation and deepen scientific understanding in the rapidly expanding field of advanced functional nanomaterials.
