Mesophase formation behavior in petroleum residues
Subhash Kumar, Manoj Srivastava 한국탄소학회 Carbon Letters 12 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.3 3 171-182 (12 pages)
Mesophase pitch is an important starting material for making a wide spectrum of industrial and advanced carbon products. It is produced by pyrolysis of petroleum residues. In this work, mesophase formation behavior in petroleum residues was studied to prepare environmentally- benign mesophase pitches, and the composition of petroleum residues and its influence on the mesophase formation was investigated. Two petroleum residues, i.e., clarified oil s (CLO-1, CLO-2) obtained from fluid catalytic... -

화학적으로 안정한 다환 방향족 염료을 페수처리시설이나 천연적인 분해에 통해서 제거시키는 것이 비효율적인 것으로 알려져 있다. 다환 방향족 염료를 제거를 위하여 우리는 여러 버섯균류의 조사하였다. 한국의 야산에서 채집된 230종의 버섯으로부터 조직분리를 통하여 100개 버섯 균을 분리하였다. 염료(Bromophenol Blue, Congo Red, 혹은 Methylene Blue)를 함유한 배지에 분리된 버섯 균을 10%로 접종한 후 7일 동안 정치배양 혹은 진탕배양하여 염료제거능이 우수한 6 종의 버섯 균을 선발하였다. 이렇게 선발된 버섯 균을... -
Applications of carbon-based materials in solid phase micro-extraction: a review
Jian Guo, Soo-Jin Park, Long-Yue Meng, Xinghua Jin 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 2 10-17 (8 pages)
With continuous development in the field of sample preparation technology, solid phase micro-extraction (SPME) has been widely used in analytical chemistry for high extraction efficiency and convenient operation. Different materials lead to different extraction results. Among existing materials, carbon-based materials are still attracting attention from scientists due to their excellent physical and chemical properties as well as their modifiable surfaces, which could enhance the adsorption...
