Micro-sized carbon with dimple patterns prepared using an electro-spray method
Mi-Seon Park, Young-Seak Lee 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.3 9 215-218 (4 pages)
Carbon micro particles with dimple patterns were produced by electro-spraying a solution of pitch in tetrahydrofuran. Particle formation depended on separation in an electrical field and volatilization of the solvent. More than 80% of the obtained carbon exhibited an average particle size of less than 50 μm. X-ray diffraction analysis suggests that the carbon with dimple patterns has increased crystallinity after heat treatment. -
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... -
Hierarchical porous carbon nanofibers via electrospinning
Aikifa Raza, Jiaqi Wang, Shan Yang, Yang Si, Bin Ding 한국탄소학회 Carbon Letters 14 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.1 1 1-14 (14 pages)
Carbon nanofibers (CNFs) with diameters in the submicron and nanometer range exhibit high specific surface area, hierarchically porous structure, flexibility, and super strength which allow them to be used in the electrode materials of energy storage devices, and as hybrid-type filler in carbon fiber reinforced plastics and bone tissue scaffold. Unlike catalytic synthesis and other methods, electrospinning of various polymeric precursors followed by stabilization and carbonization has become a... -

Preparation and Cfaracterization of Pan-based Wed of Carbon Nanofibers by Electrostatic Spinning
Chan Kim, Kap Seung Yaung 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2002, Vol.3 No.4 5 210-218 (9 pages)
탄소섬유는 출발 원료에 따라 polyacrylonitrile(PAN)계, 피치계, 레이온계 등으로 구분할 수 있으며, 형태에 따라 장섬유와 단섬유로 구분된다[1-3]. 장섬유는 프리프레그나 필라멘트용으로 이용되기 때문에 사절이 없는 방사기술이 요구되며, 보통 응융방사나 용액방사하여 권취하는 방법에 의해 제조되고 있다. 단섬유는 각종 전극재, 복합재료용 필러, 단열재 등으로 이용된다. -
Reduction of Tomato spotted wilt virus on Table Tomatoes in Greenhouses by Soil Fumigation
한국식물병리학회 The Plant Pathology Journal 6 Pages
한국식물병리학회 The Plant Pathology Journal 2009, 25권 2호 6 151-156 (6 pages)
at that time. The rate of viruliferous thrips with TSWV on lettuce and red pepper was 20.2% and 52.1%, respectively, in greenhouses. Dazomat, soil fumigation pesticide, reduced TSWV disease incidence drastically on table tomato as treatment the chemical into the soil with humidity in early spring in 2006 and 2007. Spraying insecticide periodically after treatment with Dazomat was more effective to control TSWV than spraying if on plants or applying into the soil of the insecticide during growing... -
