| Research Abstract |
The anisotropic surface modification of the particles using the sudden heating of shockwaves were performed. We have used the laser apparatus as the shockwave source, and the supercritical CO_2 was used as the surrounding media. When we used water as the solvent, the plasmonic peak appeared around 400 nm, but it disappeared when the solvent was changed to toluene. It was due to the surface modification of the silver nanoparticles by carbon, but it was unsuccessful to confirm the anisotropic modification of the surface of the silver nanoparticles using the high resolution TEM. It was probably because most of the particles existed in the solvent but not on the boundaries of the gas-liquid interfaces.
