Abstract: Nanotechnology is the cutting edge and modern emerging technology due to its wide range of applications in many fields of sciences and technologies like ceramics industry, cosmetics, detergents, fertilizers, mobile devices etc. Metallic nanoparticles are considered the building blocks of nanotechnology. Among the metallic nanoparticles, silver nanoparticles are considered to be the more emerging nanoparticles due to its wide range of applications. Nanomaterial’s have unique optical, catalytical, and electromagnetic properties. Nanotechnology provides a platform for the engineers to synthesize nanoparticles and to know the properties of by characterizing the size, morphology status to produce potential multitude products. To get maximum and unique size and morphology of nanoparticles, different procedure i.e. synthetic routes and optimal conditions are being choosing to get maximum nanoparticles e.g. pH, temperature, concentration of supernatant, concentration of extract, method employing for the synthesis of nanoparticles and time of stirring. The aim of this review article is to comparative study of different method of nanoparticles synthesize. The fast and more reliable method is Biosynthesize method due to Eco-friendly, cost efficient.

Abstract: Carbon nanotubes (CNTs), also known as Bucky tubes, are a class of nanomaterials consisting of a two-dimensional hexagonal lattice of carbon atoms that bend in one direction and combine to form hollow cylinders. Carbon nanotubes are cylindrical isotropic forms of carbon, between Fullerene (0-dimensional) and Graphene (2-dimensional), and technologies are now available for mass production of nanotubes, including electric arc discharge, laser ablation, chemical vapor deposition (CVD) and high-pressure carbon monoxide disproportionation (HiPCO), consisting of a single layer of carbon atoms (graphene). The pieces are rolled up to make up. They can be single-walled carbon nanotubes (SWCNT) with a diameter of less than 1 nanometre (nm) or multi-walled carbon nanotubes (MWCNT), consisting of several concentrically interconnected nanotubes with a diameter of more than 100 nm, which can reach lengths of a few micrometers or even millimeters. Furthermore, as one-dimensional nanomaterials, these cylindrical carbon molecules have excellent mechanical stiffness and tensile strength due to the nanostructure of carbon nanotubes and the strength of the interatomic bonding. Carbon nanotubes also have certain chemical stability, high electrical conductivity, and excellent thermal conductivity, so carbon nanotubes have a promising future and will be widely used in alloy reinforcement materials, load material electrodes, conductive films, etc.
