Reaction and material processing using supercritical plasma by discharge and laser irradiation

利用放电等离子体在超临界或加压条件下进行各种染料和丙氨酸等氨基酸的聚合等化学反应作为物质转化过程。阐明了排放强度与化学反应的关系及反应机理。在超临界流体中激光烧蚀金属时，纳米颗粒和纳米团簇的压力依赖性显著，在临界压力附近促进了纳米颗粒的生成。给出了等离子体发射强度的关系。开发了水热电解法转化材料的工艺。

Chemical reactions including polymerization of various dyes and amino acids such as alanine were proceeded as material conversion processes using discharge plasma in supercritical or gas-liquid interface under pressurized condition. The relationship between emission intensity and chemical reaction, and reaction mechanism were clarified.For laser ablation of metals in supercritical fluid, pressure dependence of nano particles and cluster was significant and particle generation is promoted near the critical pressure. The relationship of emission intensity of plasma was shown. Material conversion process was developed using hydrothermal electrolysis.
