An overview of new oxidation methods for polyacrylonitrile?based carbon fibers
Hye Kyoung Shin, Mira Park, Hak-Yong Kim and Soo-Jin Park 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.1 2 11-18 (8 pages)
The process of oxidizing polyacrylonitrile (PAN)-based carbon fibers converts them into an infusible and non-flammable state prior to carbonization. This represents one of the most important stages in determining the mechanical properties of the final carbon fibers, but the most commonly used methods, such as thermal treatment (200°C to 300°C), tend to waste a great deal of process time, money, and energy. There is therefore a need to develop more advanced oxidation methods for PAN precursor... -
Overlook of carbonaceous adsorbents and processing methods for elemental mercury removal
Kyong-Min Bae, Byung-Joo Kim and Soo-Jin Park 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.4 2 238-246 (9 pages)
People have been concerned about mercury emissions for decades because of the extreme toxicity, persistence, and bioaccumulation of methyl Hg transformed from emitted Hg. This paper presents an overview of research related to mercury control technology and identifies areas requiring additional research and development. It critically reviews measured mercury emissions progress in the development of promising control technologies. This review provides useful information to scientists and engineers... -
Enhanced electrocapacitive performance and high power density of polypyrrole/graphene oxide nanocomposites prepared at reduced temperature
Harish Mudila, Varsha Joshi, Sweta Rana, Mohmd. Ghulam Haider Zaidi, Sarfaraz Alam 한국탄소학회 Carbon Letters 9 Pages
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... -
Superhydrophobic carbon-based materials: a review of synthesis, structure, and applications
Long-Yue Meng, Soo-Jin Park 한국탄소학회 Carbon Letters 16 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.2 5 89-104 (16 pages)
Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as... -

파이렉스 #7740 유리박막을 이용한 MEMS용 MLCA와 Si기판의 양극접합 특성
정귀상, 김재민, 윤석진, Chung. Gwiy-Sang, Kim. Jae-Min, Yoon. Suk-Jin 한국센서학회 센서학회지 8 Pages
한국센서학회 센서학회지 2003, Vol.12 No.6 265-272 (8 pages)
본 논문은 파이렉스 #7740 유리 박막을 이용한 MEMS용 MLCA (Multi Layer Ceramic Actuator)와 Si기판의 양극접합 특성에 관한 것이다. 최적의 RF 마그네트론 스피터링 조건 (Ar 100%, input power $1;W/cm^2$)하에서 MLCA기판위에 파이렉스 #7740 유리의 특성을 갖는 박막을 증착하였다. $450^{circ}C$에서 1시간 열처리한 다음, -760 mmHg, 600V 그리고 $400^{circ}C$에서 1시간동안 양극접합했다. 그 다음에 Si 다이어프램을 제조한 후, MLCA/Si 접합계면과 MLCA 구동을 통한 Si 다이어프램 변위특성을 분석 및 평가하였다. 다이어프램...
