Résumé :

Guide to the design, synthesis, and applications of core-shell nanoparticles

Core-Shell Nanomaterials provides a thorough exploration of core-shell nanomaterials, detailing their fundamental architectures and synthesis methods (e.g., sol-gel, hydrothermal), advanced characterization techniques (TEM, XRD), and applications in energy (batteries, solar cells), environment (water purification, carbon capture), and biomedicine (drug delivery, theranostics). Emerging trends like smart coatings and additive manufacturing are highlighted, alongside challenges such as toxicity, cost, and regulatory hurdles.

Written by a team of highly qualified authors, Core-Shell Nanomaterials includes information on:

• Unique properties of core-shell structures, including structural and morphological characteristics, enhanced stability and core protection, and tunable optical and electronic properties
• Physical methods for core-shell synthesis including sputtering and pulsed laser deposition, mechanical milling and ball milling, and electrospinning and physical encapsulation
• Scalability and cost-effective manufacturing, covering batch versus continuous production, challenges in quality control, and automated and AI-driven synthesis methods
• Microscopy characterization techniques including scanning electron microscopy (SEM), transmission electron microscopy (TEM), and forced ion beam (FIB) and 3D imaging techniques
• Thermal and mechanical analysis through thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), nanoindentation, and dynamic mechanical analysis (DMA)

By drawing from both academic research and emerging industrial trends, Core-Shell Nanomaterials serves as a valuable reference for graduate students, researchers, and professionals in materials science, nanotechnology, chemistry, and engineering seeking a multidimensional perspective on the future trajectory of these exciting nanomaterials....
