Adrian Vîlcu、Liliana Hristian、L Bordeianu Demetra 等 4 位作者2014-05-01DOAJ (DOAJ: Directory of Open Access Journals)

The paper analyses the tensile behavior of woven fabrics made from 45%Wool + 55% PES used for garments. Analysis of fabric behavior during wearing has shown that these are submitted to simple and repeated uni-axial or bi-axial tensile strains. The level of these strains is often within the elastic limit, rarely going…

One-step crosslinking and functionalization of electrospun fibers

Emily Christina Buck、Caroline L. Schauer2014-05-01OpenAlex

One-step crosslinking of electrospun poly(allylamine) fibers was investigated for two new crosslinking agents: hexamethylene-1,6-diamino(carboxysulfonate) (HDACS) and genipin. Electrospun fibers have high surface area to volume ratios and high porosity, making them excellent candidates for water filtration membranes.…

박현서、정성운、황주형 等 9 位作者2014-05-01한국열환경공학회 학술대회지

우리나라에서 발생하는 폐기물 중 측정 폐기물은 무기물질의 중금속이 대부분이다. 이러한 중금속들은 토양 및 식물에 생물학적으로 농축되므로 food chain을 통해 인체 에 농축될 수 있다. 중금속 물질의 특성으로서는 용출의 우려가 있으므로 최종 처분 시 고형화 방법을 통하여 자연 및 인간환경에 미치는 영향을 최소화하는 방식을 선택 해야 한다. 우리나라는 대부분 해양투기 또는 시멘트 고형화 방법을 이용하고 있으나, 이 방법은 산성우나 해수와 같은 특정 환경에 노출되었을 때 고형시편에 함유되어 있 는 유해중금속이 용출될 수가 있고, 폐기물 중 구리, 크롬, 카드뮴, 아…

폐기물 최소화 정책과 같은 폐기물을 자원화하고 환경오염을 최소화하려는 관리정책 이 생겨남에 따라 폐기물 최소화 정책에서 파생된 생산자책임재활용제도(EPR: Extended Producer Responsibility)로 인하여 폐기물의 원천감량화와 재활용이 촉진되 고 있다. 그러므로 기존에 스토카식 소각로에서 처리하던 폐기물을 EPR제도로 인해 다 른 방안을 모색하게 되었다. 이에 따라 재활용 폐기물의 처리를 위해 고안된 방법이 열분해 가스화 용융기술이다. 이러한 열분해 가스화 용융기술을 통하여 국내에서 재활 용되지 않고 소각이나 매립에 의존하고 있는 알루미늄 포장재…
