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. Solubilization of the composite in aqueous starch solution. Colloidal polyaniline and Au-NPs-PANI composite nanoparticle synthesis.
