Thermolysis Technology for Waste Treatment in Europe 스크랩

  • 김명수

  • 재료

Optimal waste management today requires more effective, more ecological and more econornical means than in the past. New technologies must be also developed and applied in order to recycle the maximum amount of waste possible with disposal of only final residue. Thermolysis(low-temperature-pyrolysis)processes treat waste by means of physico-chemical transformation. It acts on organic matter, at moderate temperatures, transforming it into fuel under the combined effects of heat and the absence of oxygen, and finally we can produce energy as necessary. Moreover, the process guarantees almost 100% recovery of inert recyclable matter.

1. 자료명: Radiation Issues, Environments, Effects and Considerations 2. 저자: National Semiconductor Corporation 3. 출판사: National Semiconductor Corporation 4. 출판날짜: March 1999 5. URL: www.national.com/appinfo/milaero/files/ROM_Issues.pdf 6. 내용소개: 본 자료는 방사시 발생하는 문제점, 방사환경, 방사가 미치는 효과 및 방사 설계시 고려사항등에 관해 다루고 있다. 집적회로의 제작에 있어 공정, 패키징, 재료, 인터커넥트, 리소그라피 및 다른 중요한 분야는 점점 더 복잡한 소자 (예를 들면, 시스템 온 칩), 더 우수한 동작특성 및 더 낮은 가격에 초점을 맞추고 있다. 따라서 CMOS 기술이 지배적인 기술로서 존재할 것이다. 빠른 기술발전의 대부분은 CMOS 기술에서 형성되고 있으며, 2010년까지는 계속될 전망이다. 이러한 빠른 변화는 방사효과에 대해 더욱더 많은 새로운 도전을 창출할 것이다. 0.1m m수준까지 CMOS 기술이 지원됨에 따라 이러한 효과는 더욱더 중요한 고려사항이 되고 있다. 이 자료의 분석은 Star V-Ray사에 계시는 신영훈박사님께서 수고해 주셨습니다. 궁금하신 점은 박사님께 문의하시기 바랍니다. e-mail: yhshin@starvray.com 첨부 .Radiation Issues, Environments, Effects and Considerations 신영훈.pdf *.원문은 관련 URL을 참고하시기 바랍니다.
