Spectroscopic investigations of fluid flow in soap bubbles and au nanoparticles and its polyaniline composite synthesis

Abstract

This thesis consists of experimental investigations in the following two areas i Stabilization of single soap bubbles and their spectroscopic investigation Observation o Marangoni effect driven upwardly mobile fluid layer in a soap bubble film Control of the fluid movement by controlling surfactant concentration gradient ii Synthesis of Au nanoparticles NPs from reduction of HAuCl4 by H2O2 Generation of shape selected Au NPs Preparation of Au NP conducting polyaniline PANI composite
