Atomic absorption spectroscopy

are inevitable at the time of production can alter the structural properties of any engineering materials. Developing graphene with specific structural properties depends upon controlling these defects, either by removing or deliberately engineering atomic structure to gain or tailoring specific properties. In the present article, a comprehensive review of defective graphene sheets with respect to its mechanical and thermal properties are presented and examined. Key Words: Graphene; point defects; line

August 2015  Absorption coefficient The absorption coefficient decides how far into a material, the light of a particular wavelength can penetrate before it is absorbed. The photons that have an energy above the band gap, depends on the wavelength and its absorption coefficient is not constant. The likelihood of retaining a photon relies on upon the probability of having a photon and an electron connect so as to move starting with one energy band then onto the next. The absorption is relatively

Chapter 1 Introduction 1.1 Background Nanotechnology is a field of applied science, focused on the design, synthesis, characterization and application of materials and devices at the nanoscale. This is an emerging field which plays a major role in the development of innovative methods to produce new products. Because of its greater role in enhancing the performance of several existing technologies, it is gaining high attention. Properties of materials often change dramatically when size reduces
