MAGNETIC CORE SHELL STRUCTURES: from 0D to 1D assembling

Abstract

Material research and development studies are focused on different techniques of bringing out nanomaterials with desired characteristics and properties. From the point of view of materials development, nowadays scientists are strongly focused on obtaining materials with predefined characteristics and properties. The morphology control seems to be a determinant factor and increasing attention is devoted to this aspect. At this moment it is possible to engineer the material's features by using different methods and materials combination for both medical and industrial applications. In the applications of chemistry and synthesis, biology, mechanics, optics solar cells and microelectronics tailoring the adjustable parameters of stoichiometry, chemical structure, shape and segregation are evaluated and opens new fields. Because of the magnetic features of nanoparticles and durable particle size, less than 100 nm, this study is aiming to describe their uses in practical applications. That's why the whole hydrodynamic magnetic core shell topic will be reviewed on this paper. Additionally, the properties acting in general sight in solid-state physics are utilized for material selection and for defining issue connecting the core, shell structure and their producing properties. Here, in the study of core/shell nanoparticle various physical and chemical synthesis routes and the effect of electrospun method are briefly discussed. Starting from a real void of the scientific literature, the existent data related to the 1D magnetic electrospun materials are reviewed. The perspectives in the medical, environmental or energetic sector is great and bring some real advantages related to the 0D core@shell structures because both mechanical and biological properties are dependent on the morphology of the materials.

Electrospun Fibers Containing Emissive Hybrid Perovskite Quantum Dots

“…A similar effect has been realized via a 1-D fiber, which is like a shell with embedded QD clusters using a facile route of electrospinning . The shell is formed using a clear dielectric polymer into a fiber with the clusters of OIP QDs homogeneously distributed along its length. , High molecular weight (∼100 kDa) and low refractive index polymers like PMMA and PS can be pulled into thin fibers of diameters ranging from 0.1 to 10 μm and of several millimeters in length, using electrospinning. − Aligned and random polymer fibers are of interest for 3-D microcavity for lasers, , aligned channels for field effect transistors, , high response linear photodetector arrays, − flexible supercapacitors, and many more applications. Unique 3-D geometries obtained in electrospun fibers have shown to host whispering gallery modes and allow for high quality-factor and dynamic tuning range of the propagation wavelength. , …”
