Significance of carbon matrices in synthesis of magnetic core-shell magnetic nanostructures*

A carbon matrix plays a crucial role in the synthesis of magnetic core-shell nanostructures by providing a stable, protective environment for the magnetic nanoparticles, allowing for precise control over their size, shape, and dispersion while also enhancing their stability against oxidation and agglomeration, making them suitable for various applications like drug delivery, environmental remediation, and magnetic data storage; essentially acting as a support structure that can be tailored to optimize the magnetic properties of the embedded nanoparticles. This study explores the innovative use of carbon matrices in the synthesis of magnetic nanoclusters, with a focus on their structural and morphological properties. The research highlights the significance of porphyrins and phthalocyanines as carbon matrices, examining their unique characteristics and applications in nanoparticle synthesis. Employing advanced characterization techniques such as Scanning Electron Microscopy (SEM) and Powdered X-ray Diffraction (PXRD), we analyze the porosity and layer sizes of these carbon matrices and their impact on magnetic properties. A novel algorithm, integrating node extraction and 2D Gaussian mapping, is developed to enhance the accuracy of morphological analysis. Our findings reveal the critical role of carbon matrix properties in influencing the magnetic behavior of nanoparticles, providing valuable insights into the design and development of advanced magnetic nanomaterials.
