A highly purified (Na+, K+)-ATPase from the rectal gland of Squalus acanthias and from the electric organ of Electrophorus electricus has been used to raise antibodies in rabbits. The 97,000 dalton catalytic subunit and glycoprotein derived from the rectal gland of spiny shark were also used as antigens. The two (Na+, K+)-ATPase holoenzymes and the two shark subunits were antigenic. In Ouchterlony double diffusion experiments, these antibodies formed precipitation bands with their antigens.... -

Particulate matter research is of great significance in solving atmospheric environment problems. The heterogeneous reaction of mixed gas on different mineral oxides and coal ash was studied based on a laboratory-built aerosol generating reactor. The product formed on particles was investigated by ion chromatography (IC). SO2 and NO2 could react on oxides to form secondary particles and the order of reactivity of mineral oxides under laboratory reaction conditions is: Al2O3>MgO>CaO>>SiO2, Fe2O3.... -

Ji Hong Kim, Jong Gu Kim, Chul Wee Lee, Ki Bong Lee, Ji Sun Im 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2017, Vol.23 7 48-54 (7 pages)
This research considers the effect of added mesophase pitch (MP) as an additive during the pitch synthesis reaction of pyrolyzed fuel oil (PFO). Two effects are generated by adding MP. One is an enhancement of thermal stability due to the high thermal property of the additive; the other is that the volatile compounds that were removed by vaporization of PFO during the thermal reaction can participate in the pitch synthesis reaction (PFO→pitch) more efficiently. The effect differs according to... -

한국탄소학회 Carbon Letters 2014, Vol.15 No.3 3 171-179 (9 pages)
An attempt was made to investigate the effect of the preparation temperature on the electrocapacitive performance of polypyrrole (PPY)/graphene oxide (GO) nanocomposites (PNCs). For this purpose, a series of PNCs were prepared at various temperatures by the cetyltrimethylammonium bromide-assisted dilute-solution polymerization of pyrrole in presence of GO (wt%) ranging from 1.0 to 4.0 with ferric chloride as an oxidant. The formation of the PNCs was ascertained through Fourier-transform infrared... -

Hughes 등은 철 도가니 안에서 수소와 메탄의 혼합물로부터 모발형상의 기상성장 탄소섬유가 생성한 것을 발견하였고, 섬유는 화학기상증착법에 의해 형성된 직경이 약 20m의 탄소 필라멘트형태임을 보고하였다. 이후에 Davis 등이 전자 현미경을 사용하여 나노 크기의 직경을 가진 탄소 필라멘드를 처음으로 관찰하였고, 현재까지 많은 연구자들이 Ni,Fe,Co 및 이러한 금속들의 합금을 촉매로 이용하여 탄소나노섬유를 성장 시키는 기술을 확립하였다. -

최근 국내 석산에서의 골재공급이 부족해지면서, 성토재 등의 저급재료로 재활용 되던 폐 콘크리트 순환골재의 용도를 점차 구조용 콘크리트 및 도로 포장재와 같은 고급재료로 재활용하기 위한 노력이 계속되고 있다. 이러한 노력의 일환으로 정부는 2009년 순환골재 품질기준을 제정하였으며, 순환골재가 기존보다 고급재료의 용도로 활용될 수 있는 제도적 기반을 마련하였으나, 현재까지 빈배합 콘크리트 기층용으로서의 순환골재의 활용은 매우 낮은 형편이다. 본 연구는 순환골재 품질기준에 규정되어 있는 빈배합 콘크리트용... -

건설폐기물의 재활용방법 중 하나는 폐콘크리트 재생골재를 도로포장재료로 활용하는 것이다. 하지만 재생골재에 대한 많은 연구와 기술개발에도 불구하고 생산공정에 포함된 이물질 때문에 실제 도로포장재료로의 적용은 미비한 실정이다. 본 연구에서는 재생골재내에 포함된 이물질의 특성에 따라 무기이물질과 유기이물질로 구분하였으며 , 각 이물질이 포장 공용성에 미치는 영향을 제시하였다. 또한 재생골재내에 포함된 무기이물질 함유량과 압축강도와의 관계, 유기이물질 함유량과 수정 CBR과의 상관관계를 통하여 도로포장층인... -

건설폐기물 발생량이 급증함에 따라, 폐콘크피트를 파쇄가공한 순환골재를 구조체 콘크리트용으로 사용할 필요성이 증대하고 있다. 그러나 순환골재에는 콘크리트의 물리적 특성에 악영향을 미치는 각종 이물질이 포함되어 있어, 사전에 이물질 함유량을 적절히 판단하기 위한 시험방법이 요구된다. 본 연구에서는 순환잔골재와 순환굵은골재에 포함되어 있는 각종 이물질 함유량을 육안관찰에 의하여 선별하기 위한 시험방법을 개발하였으며, 그 결과는 다음과 같다. 1. 현행 KS F 2576(재생골재의 이물질 함유량 시험방법)은 시험대상...
