세계화에 대한 대응: 국제화와 대학 환경의 급진적 변화
한국교육학회 교육학연구 2016, 54권 2호 12 341-372 (32 pages)
본 서울대학교 사례 연구는 세계화에 대응하기 위해 나타나는 대학의 국제화 노력과 급진적으로 변화하는 학교의 변화를 분석하였다. 분석 결과에 따르면, 최근 대학이 국제화를 표방하면서 경쟁, 효 율성, 수익성이라는 시장 개념이 대학의 교육 환경에 빠르게 침투하고 있음을 확인하였다. 이것은 대 학의 국제 경쟁력 강화를 위한 유학생 유치와 연구비 확보를 위한 전략을 통해 확인할 수 있다. 대학 에서 나타나는 국제화(internationalization)의 모습은 국제주의(internationalism)라기 보다는 세계교육 시장에서 경쟁력 강화를... -
Preparation of photoresist-derived carbon micropatterns by proton ion beam lithography and pyrolysis
Hui-Gyun Nam, Jin-Mook Jung, In-Tae Hwang, Junhwa Shin, Chang-Hee Jung, Jae-Hak Choi 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 8 55-61 (7 pages)
Carbon micropatterns (CMs) were fabricated from a negative-type SU-8 photoresist by proton ion beam lithography and pyrolysis. Well-defined negative-type SU-8 micropatterns were formed by proton ion beam lithography at the optimized fluence of 1×1015 ions cm?2 and then pyrolyzed to form CMs. The crosslinked network structures formed by proton irradiation were converted to pseudo-graphitic structures by pyrolysis. The fabricated CMs showed a good electrical conductivity of 1.58×102 S cm?1 and a... -
Catalytic hydrogenation-assisted preparation of melt spinnable pitches from petroleum residue for making mesophase pitch based carbon fibers
Dong Hun Lee, Jisu Choi, Young Se Oh, Yoong Ahm Kim, Kap Seung Yang, Ho Jin Ryu, Yong Jung Kim 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 4 28-35 (8 pages)
We demonstrated an effective way of preparing melt spinnable mesophase pitches via catalytic hydrogenation of petroleum residue (fluidized catalytic cracking-decant oil) and their subsequent thermal soaking. The mesophase pitches thus obtained were analyzed in terms of their viscosity, elemental composition, solubility, molecular weight, softening point and optical texture. We found that zeolite-induced catalytic hydrogenation under high hydrogen pressure contributed to a large variation in the... -
Preparation of carbon discs using petroleum-based binder pitch reformed with carbon black
Sangmin Lee, Kyung Hoon Kim, Young-Seak Lee 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2017, Vol.23 13 84-87 (4 pages)
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... -
Effect of added mesophase pitch during the pitch synthesis reaction of PFO
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... -
Mechanical and electrical properties of epoxy resin/epoxidized castor oil/carbon fiber cloth composites
Fan-Long Jin, Heng Zhang, Shan-Shan Yao, Soo-Jin Park 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 12 105-109 (5 pages)
Carbon fibers (CFs) have a unique combination of outstanding mechanical, physical, and chemical properties and are among the materials most frequently used in the preparation of a large variety of composites [1-5]. CF-reinforced polymer composites have been widely used in many advanced technological fields, such as aerospace, engineering, sporting goods, automobiles, and marine industry during the past few decades due to their excellent properties, including high strength-to-weight ratios, light... -
Adsorption characteristics of heavy metals ions by physical activation on coal tar pitch-based activated carbon fibers
Bo-kyung Choi, Jae-Kyoung Ko, Soo-Jin Park, Min-Kang Seo 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 10 96-100 (5 pages)
by various industries. This wastewater flows into rivers, pollutes water supplies, and can contaminate the drinking water supplied to people [1-3]. Powder or activated carbons are being widely used today to mitigate polluted water from industrial sources and contaminated supplies. To make up for the limitations of such materials, there has been strong interest in the use of activated carbon fibers (ACFs) as adsorbents, because they offer excellent adsorption performance and processability [4-6]. -
Tribological properties of carbon fiber-reinforced aluminum composites processed by spark plasma sintering
Ki Hoon Jung, Seungjin Nam, Sung-Soo Kang, Bon-Cheol Ku, Yun Hyuk Bang, Jun Yeon Hwang 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 14 103-106 (4 pages)
The development of light-weight and high-strength materials have gained attention to meet the evergrowing demands for safer and fuel-efficient automobiles. Thus, the importance and applications of composite materials are gradually increasing [1]. In the field of metal-matrix composite manufacturing, reinforcing agents are added to the metal matrix in the form of powders, whiskers, and fibers to improve the mechanical properties of metals [2]. Fibers have been used since the 1950s as structural... -
Morphologies and surface properties of cellulose-based activated carbon nanoplates
Seulbee Lee, Min Eui Lee, Min Yeong Song, Se Youn Cho, Young Soo Yun, Hyoung-Joon Jin 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 5 32-38 (7 pages)
In this study, cellulose nanoplates (CNPs) were fabricated using cellulose nanocrystals obtained from commercial microcrystalline cellulose (MCC). Their pyrolysis behavior and the characteristics of the product carbonaceous materials were investigated. CNPs showed a relatively high char yield when compared with MCC due to sulfate functional groups introduced during the manufacturing process. In addition, pyrolyzed CNPs (CCNPs) showed more effective chemical activation behavior compared with... -
Adsorptive removal of atmospheric pollutants over Pyropia tenera chars
Heejin Lee, Rae-su Park, Hyung Won Lee, Yeojin Hong, Yejin Lee, Sung Hoon Park, Sang-Chul Jung, Kyung-Seun Yoo, Jong-Ki Jeon, Young-Kwon 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 10 79-88 (10 pages)
As a replacement for activated carbon, biochar was synthesized and used for the adsorptive removal of formaldehyde and nitrogen oxide. Biochar was produced from the fast pyrolysis of the red marine macro alga, Pyropia tenera. The P. tenera char was then activated with steam, ammonia and KOH to alter its characteristics. The adsorption of formaldehyde, which is one of the main indoor air pollutants, onto the seaweed char was performed using 1-ppm formaldehyde and the char was activated using a...
