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

在加压条件下，利用放电等离子体在超临界或气液界面进行包括各种染料和丙氨酸等氨基酸的聚合在内的化学反应，作为材料转化过程。阐明了发射强度与化学反应的关系和反应机理，对于超临界流体中金属的激光烧蚀，纳米粒子和团簇的压力依赖性显著，在临界压力附近促进了粒子的生成。给出了等离子体发射强度之间的关系。利用水热电解法开发了材料转化工艺。

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.
