The organic carbonaceous materials play an important role in governing the optical transport phenomena and bioavailability of nanomaterials. The nanomaterials established for the absorption of neutral organic compounds do not always apply to the facts and the importance of accounting for the particular sorption behavior of being increasingly recognized. This work carries out a study on the reaction of synthesis and optical and electrical characterizations of CNT carbon nanostrutures. The crystal size was calculated by using Scherer equation as 55 nm and its thermal diffusivity 4.515 × 10-7 m2/sec, the conductivity of the sample was measured as 75.69. At the surface, the progressive incorporation of dopant triggers the diffusion of CNT to the surface, which results in fast formation carbon nanostructures of CNT, its crystallite size lies in the range of 36 nm.

Stable oxides of Ni, Fe and Co nanoparticles are synthesized by chemical route using leaf extraction. Structural, biological morphological and magnetic properties were investigated. X ray pattern shows a polycrystalline structure of samples. Diffraction planes of (200), (122) and (200)-oriented crystal structures were revealed by X-ray pattern for NiO, Fe2 O3 and CoO respectively. Hexagonal, orthorhombic and cubic crystal structures have been revealed respectively for NiO Fe2 O3 and CoO nanoparticles. Microscopic structure has been detected by using of Scanning Electron Microscopy. Ni, Fe and Co is present at 71%, 78.8%, 79% as indicated by EDS analysis respectively. Mass magnetization values of 51, 61 and 54 emu/g are recorded for NiO, Fe2 O3 and CoO nanoparticles.

This article provides an overview of research on nanoparticles quantum confinement processing of nanoparticles and processing applications in theoretical concepts of optical and electrical studies. The main text of this review is organized into two sections. Section 1 discusses the use of optical methods for the applications of nanoparticles and its model exciton properties of nanostructured particles and in section 2 discusses for dispersion of agglomerated nanoparticles and its various equations for all, such as photo luminescent and transparent conductive materials. These studies explain the theoretical equations of both nanoparticles and thin film.
