| 살균처리란 무엇인가? | 이러한 미생물의 오염제거 는 미생물 종의 분해나 제거를 의미하며. 살균처리 (bactericidal)는 세균의 파괴, 증식방지 혹은 병리 작용의 억제를 목적으로 살균, 소독, 세척과 함께 무균 처리 및 방부처리까지 포함하는 복합용어이다 Shimizu et al., 2011). | |
| 실내에 존재하는 입자 및 가스상 물질들을 동시에 제거하는 방식에는 어떠한 것들이 있는가? | 그동안 실내에서의 공기청정이 점차 중요해짐에 따라 실내에 존재하는 입자 및 가스상 물질들을 동시에 제거하는 방식들이 다양하게 개발되어 왔다. 이러한 기술로는 필터식, 전기집진 RNS식, 이온플라즈마 방식, UV 광촉매방식 및 여러 방식의 혼합(hybrid)방식 등이 있다. 이 중 저온플라즈 마방식의 활성종(Reactive species, ROS, RNS)을 이용한 공기청정살균방식은 인플루엔자, 세균, 곰팡이 등의 오염물을 제거하는데 큰 효과가 있는 것으로 알려져 있다(Kitano et al. | |
| 인공적 플라즈마는 어떻게 활용되는가? | 하지만 지구는 태양처럼 핵융합반응이 일어날 수 있는 초고온•고압상태의 환경이 아니기 때문 에, 자기장이나 레이저를 이용해서 태양과 같은 인공적인 핵융합장치 만들 수 있는데, 이렇게 기체에 초전류 고주파, 전자빔 등의 전기적 에너지를 가하여 플라즈마를 생성한 다음에 전자기장 등을 이용하여 플라즈마 상태를 유지할 수 있으면서 높은 온도, 압력, 에너지, 자력, 전력 등을 얻을 수 있다. 즉, 인공적 플라즈마는 고온상태로 핵융합발전 및 용접 등에 활용되고, 저온상태로 100℃ 이하의 낮은 온도 상태에서는 악취 및 독성물질을 제거하거나 그람양성과 그람음성 세균, 바이러스, 곰팡이 등에 탁월한 살균기능으로 피부 등의 미용과 창상(chronic wound)치료에 유용하게 사용되고 있다(Heo., 2003; Heinlin et al. |
