Nanomaterial and its spectral, electrical and magnetic properties

Author(s): Saema Salim
Abstract:
Nanomaterials are those materials that have at least one dimension at nanoscale (less than 100nm). In this current study, the magnetic, electrical, spectral properties of nanomaterials were studied. Magnetic Properties of Nanoparticles refers to magnetic materials such as super-paramagnetic materials and magnetic susceptibility, related phenomena in super-paramagnetic particles, application of superparamagmetic materials, exchange-coupled magnetic nanomaterial specimens are classified in response to an external magnetic field. Electrical Properties of Nanoparticles discuss about the basis of electrical conductivity in nanotubes and nanorods, carbon nanotubes, photoconductivity of nanorods, electrical conductivity of nanocomposites. Characterization of Nanomaterials includes aspects on global methods for characterization, specific surface are X-Ray and electron diffraction, electron microscopy and in general consideration, with the interaction of the electron beam and specimen, localized chemical analysis in the electron microscope, scanning transmission electron microscopy uses a high-angle annular dark-field (HAADF) detector. With the help of magic angle spinning, solid state Si29 and Al27 NMR spectroscopy was used to detect two types of smectites, types of illites and a type of vermiculite. In the current research, naturally occurring samples were used. These were arranged in a ratio 2:1 clay mineral. Al27 NMR spectroscopy was used to describe the coordination of aluminum with the tetrahedron. Si29 NMR spectroscopy was used to observe the coordination of aluminum with other compound and also to detect chemical nature of interlayer species.
