Abstract

Plasmas can be made by electrical discharge on earth. Most of the plasmas on earth have been generated in low pressure environments where the pressure is less than one millionth of the atmospheric pressure. However, there are many plasma applications which require high pressure plasmas. Therefore, scientists start research on plasma generation at high pressure to avoid use of expensive vacuum equipments. Large-volume inexpensive plasmas are needed in the areas of material processing, environmental protection and improvement, efficient energy source and applications, etc. We therefore developed new methods of plasma generations at high pressure and carried out research of applying these plasmas to high tech industries representing 21 century. These research fields will play pivotal roles in material, environmental and energy science and technology in future.

지표면에서 플라즈마는 전기방전에 의하여 만들어낸다. 그래서 대부분의 플라즈마 발생은 1백만분의 1기압보다 더 낮은 기압에서 발생하고 있었다. 그러나 많은 플라즈마 응용은 고기압에서 발생한 플라즈마를 요구하고 있다. 진공펌프와 같은 고가의 장비를 피하기 위하여 과학자들은 1기압이나 그이상의 압력에서 플라즈마를 발생하는 연구를 하기 시작했다. 많은 량의 제료 공정, 환경보호와 개선, 그리고 고효율 에너지 창출과 이용 등의 분야에 플라즈마를 사용할 때에는 오직 더 많은 량의 플라즈마를 더욱 값싸게 만들 때에만 가능한 것이다. 우리는 따라서 고기압에서 플라즈마를 만들어내는 새로운 방법을 개발하고 이러한 플라즈마가 21세기 산업에 적용될 수 있는 새로운 기반을 구축하는 연구를 수행하고 있다. 이러한 기술은 미래의 재료 공정이나, 환경 그리고 에너지 분야에 지대한 영향을 미칠 것으로 생각한다.
