| Research Abstract |
We have carried out the 5-years research project on "Microplasmas" aiming at the generation of a new research field in the plasma science and technology area. Major achievements in three divisions can be listed as follows. In the first division [A01] : Generation of microplasmas, various types of microplasmas and their miniature driving power sources were developed, and the effects of gas dynamics were analyzed for the generation of microdplasmas. New electrode materials and their structures were also analyzed for improving the generation efficiency. In addition, several kinds of liquids and supercritical fluids were investigated in developing new media for microdischarges. In the second division [A02] : Diagnostics and simulation of microplasmas, charged particles and excited species were diagnosed in micro space and at the vicinity of wall surfaces for the analyses of those spatiotemporal behaviors by using various newly developed spectroscopic methods. As a topic in this division, n

ew functions were derived from arranged integration of microplasmas such as plasma photonic crystals and metamaterials for controlling electromagnetic waves in mm to sub-mm ranges. In the third division [A03] : Application of microplasmas, new and promising applications were developed enthusiastically, e.g., biomaterial processing with microplasma jet at atmospheric pressure, new material syntheses by microplasmas at cryogenic gas temperature, encapsulization of carbon nano-tubes with DNAs in electrolyte solution, micro-thruster for miniature satellite, and so on.
The stealing committee has been conducting the project to keep the functional cooperation between the 28 research groups in total. It also organized microplasma sessions in many international conferences and encouraged the participation of as many members of our project as possible. As a result the International Workshop on Microplasmas, which started in Japan just in the year of the inauguration of our project, has been continued successively in U. S. A., Germany and Taiwan. For the publication of our activities and research results, we have been operating our own URL and publishing Microplasma News Letters besides the annual symposium or exhibition open for public. Less
