Review on Electrolytic Process by Refining the Metals
Abstract: Electrolysis is a method of purifying impure metals. The crude metal that needs to be refined serves as the anode in an electrolytic cell while the metal that has been purified serves as the cathode. To ensure that the metal at the cathode is reduced extremely specifically, the electrode potential is chosen. Impurities are left behind in the electrolyte liquid as the metal is transferred from theunrefined metal of the …

Ferromagnetism in II-VI Diluted Magnetic Semiconductor, Zn0.96Mn0.04O Nanostructures by Green’s Theorem
Abstract: Ferromagnetism in II-VI diluted magnetic semiconductor, Zn0.96Mn0.04O is studied. Using the Heisenberg principle, the spin exchange between the neighboring spin is discussed. Heisenberg’s model describes the Hamiltonian of the system in terms of spin density and excitons. Mathematically, magnetic parameters such as magnetizations and magnetic susceptibility are determined by Green’s function. Ferromagnetism is expected from sp-d exchange interactions (RKKY), point defects such as oxygen vacancies, and Zn interstitial and quantum …

Floral System Act as a Reservoir for Nanobiotechnology (Silver Nanoparticles)
Abstract: The coming era of Nanotechnology is considered the first book on the topic of nanotechnology. It consists of processing of separation, consolidation and deformation of materials by one atom or by one molecule. There are two main approaches used in nanotechnology such as 1) “bottom-up” approach in which materials or devices are built from components and assemble themselves chemically by the principles of molecular recognition 2) “top-down” approach reflects the …

Gold Nanoparticles and its Preparation
Abstract: Among the colorimetric detection tactics, metallic nanoparticle based detection is gaining more attention due to quickness and less resource requirement at the point of use. Unique chemical inertness, shape, size and optical attributes of gold nanoparticles (GNPs) make them ideal for various diagnostic tools. In this approach synthesized GNPs were tabilized by citrate counter ions. These GNPs were characterized for their optical properties, shape, size, zeta potential, and dynamic light …
