수슬러지의 열분해를 통해 생성된 char를 이용하여 황화수소(H$_2$S), 메틸머캡탄(CH$_3$SH) 복합악취를 제거하기 위한 흡착제를 제조하여 흡착특성을 살펴보았다. 고정층 반응기 실험에서 최적의 L/D ratio는 1.0이었으며, 온도의 증가에 따라 파과점과 흡착능이 증가되었다. H$_2$S와 CH$_3$SH의 동시흡착 특성은 단일흡착 실험보다 파과점에 도달하는 시간과 흡착량이 증가하였고, 동일 조건에서 CH$_3$SH이 H$_2$S보다 높은 유효확산계수 값을 가지므로 빠른 흡착속도로 인한 흡착능의 증가를 보였다. 또한 하수슬러지로부터 제조된... -

The studies have provided the first comprehensive comparison of the factors regulating activation and proliferation of WC1+ and WC1- gammadelta T cells. The investigation has shown that accessory molecules essential for activation and function of WC1+ and WC1- gammadelta T cells and the sources and roles of cytokines in activation of gammadelta T cells through the T cell receptor (TCR). The study has also shown that the role of cytokines in activation and function of gammadelta T cells activated... -

Carbon materials are widely used in various industry applications, such as a carbon fibers, graphite brushes, aluminum engineering and binders, because carbon materials have high specific strength, high conductivity, excellent thermal shock resistance, and other favorable properties [1-4]. These carbon materials are prepared from various precursors, such as polyacrylonitrile (PAN), phenolic resins and pitches. Among these precursors, pitches are more economical than PAN and phenol resin, and it... -
Adsorption of Nile Blue A from aqueous solution by different nanostructured carbon adsorbents

한국탄소학회 Carbon Letters 2017, Vol.23 5 30-37 (8 pages)
Dyes are widely used in various industries including textile, cosmetic, paper, plastics, rubber, and coating, and their discharge into waterways causes serious environmental and health problems. Four different carbon nanostructures, graphene oxide, oxidized multi-walled carbon nanotubes, activated carbon and multi-walled carbon nanotubes, were used as adsorbents for the removal of Nile Blue A (NBA) dye from aqueous solution. The four carbon nanostructures were characterized by scanning electron...
