Nanotechnology is the study of the controlling of matter on an atomic and molecular scale and is also very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly. This book gathers and presents data on nanotechnology, including preparation and characterisation of gold nanoparticles in liquid solutions; Nano-ZnO reinforced poly(ether ether ketone) biocomposites; magnetic nanoparticles; nanostructured materials as catalyst supports in olefins polymerisation; gold clusters and nanoparticles in zeolites and zeolite-like materials; hybrid dispersed magnetic nanomaterial with core-shell structure based on polydiphenylamine-2-carboxylic acid; hybrid magnetic nanomaterial based on polyphenoxazine and Co nanoparticles; synthesis, characterisation and significant applications of PANI-Zr(IV)sulphosalicylate nanocomposite; and synthesis of manganese oxide nanoparticles using similar process and different precursors.
