Cho, HanIk 한국교육학회 교육학연구 22 Pages
한국교육학회 교육학연구 2013, 51권 3호 2 35-56 (22 pages)
본 연구는 대학생을 대상으로 하여 지능의 내재이론, 노력신념, 성취목표지향성, 성취정서 및 학업성취도의 구조적인 관계를 살펴보는데 목적이 있다. 연구대상은 대학생 450명이며 남학생은 197명, 여학생은 253명이다. 측정도구는 지능의 내재이론, 노력신념, 성취목표지향성, 성취정서이고 학업성취도는 2012학년도 1학기 GPA를 사용하였다. 연구결과, 지능의 내재이론에서 증진이론은 정적노력신념에 긍정적인 영향을 미치는 것으로 나타났고, 정체이론은 부적노력신념과 수행접근 목표지향성에 긍정적인 영향을 미치는 것으로... -
Fabrication of nitrogen doped ordered mesoporous carbon derived from glucosamine with hybrid capacitive behaviors
Deyi Zhang, Mei Han, Yubing Li, Bing Wang, Yi Wang, Kunjie Wang, Huixia Feng 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.23 2 9-16 (8 pages)
This paper introduces a nitrogen-doped ordered mesoporous carbon (NOMC) derived from glucosamine with hybrid capacitive behaviors, achieved by successfully combining electrical double-layer capacitance with pseudo-capacitance behaviors. The nitrogen doping content of the fabricated NOMC reached 7.4 at% while its specific surface area (SBET) and total pore volume reached 778 m2 g?1 and 1.17 cm3 g?1, respectively. A dual mesoporous structure with small mesopores centered at 3.6 nm and large... -
Effect of carbonization temperature on crystalline structure and properties of isotropic pitch-based carbon fiber
Jung Dam Kim, Jae-Seung Roh, Myung-Soo Kim 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 6 51-60 (10 pages)
Isotropic pitch-based fibers produced from coal tar pitch with the melt-blowing method were carbonized at temperatures ranging from 800 to 1600oC to investigate their crystalline structure and physical properties as a function of the carbonization temperature. The in-plane crystallite size (La) of the carbonized pitch fiber from X-ray diffraction increased monotonously by increasing the carbonization temperature resulting in a gradual increase in the electrical conductivity from 169 to 3800... -
The effect of the spinning conditions on the structure of mesophase pitch-based carbon fibers by Taguchi method
Zhao Jiang, Ting Ouyang, Xiangdong Yao, Youqing Fei 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 11 89-98 (10 pages)
Taguchi’s experimental design was employed in the melt spinning of molten mesophase pitch to produce carbon fibers. The textures of the obtained carbon fibers were radial with varied crack angles, as observed by scanning electron microscopy and polarized optical imaging. The diameter, crack angle, preferred orientation, and tensile modulus of the produced samples were examined to investigate the influence of four spinning variables. The relative importance of the variables has been emphasized... -
Pitch-based carbon fibers from coal tar or petroleum residue under the same processing condition
Jiyoung Kim, Ui-Su Im, Byungrok Lee, Dong-Hyun Peck, Seong-Ho Yoon, Doo-Hwan Jung 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 9 72-78 (7 pages)
a simple distillation under strong nitrogen flow, and further vacuum distillation to obtain a high softening point. Carbon fibers were produced from the above pitches by single-hole melt spinning and additional heat treatment, for oxidization and carbonization. Even though spinnable pitches and carbon fibers were processed under the same conditions, the melt-spinning and properties of the carbon fiber were different depending on the raw materials. A fine carbon fiber could not be prepared from... -
Study on urea precursor effect on the electroactivities of nitrogen-doped graphene nanosheets electrodes for lithium cells
Ki-Yong Kim, Yongju Jung, Seok Kim 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 5 40-46 (7 pages)
Nitrogen-atom doped graphene oxide was considered to prevent the dissolution of polysulfide and to guarantee the enhanced redox reaction of sulfur for good cycle performance of lithium sulfur cells. In this study, we used urea as a nitrogen source due to its low cost and easy preparation. To find the optimum urea content, we tested three different ratios of urea to graphene oxide. The morphology of the composites was examined by field emission scanning electron microscope. Functional groups and... -
Sorption behavior of slightly reduced, three-dimensionally macroporous graphene oxides for physical loading of oils and organic solvents
Ho Seok Park, Sung Oong Kang 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2016, Vol.18 4 24-29 (6 pages)
High pollutant-loading capacities (up to 319 times its own weight) are achieved by three-dimensional (3D) macroporous, slightly reduced graphene oxide (srGO) sorbents, which are prepared through ice-templating and consecutive thermal reduction. The reduction of the srGO is readily controlled by heating time under a mild condition (at 1 10?2 Torr and 200°C). The saturated sorption capacity of the hydrophilic srGO sorbent (thermally reduced for 1 h) could not be improved further even though the... -
Advances in liquid crystalline nano-carbon materials: preparation of nano-carbon based lyotropic liquid crystal and their fabrication of nano-carbon fibers with liquid crystalline spinning
Yong-Mun Choi, in Jung Jun Yeon, Hwang Seung Min, Kim Hyeonsu Jeong, Bon-Cheol Ku, Munju Goh 한국탄소학회 Carbon Letters 10 Pages

This review presents current progress in the preparation methods of liquid crystalline nanocarbon materials and the liquid crystalline spinning method for producing nano-carbon fibers. In particular, we focus on the fabrication of liquid crystalline carbon nanotubes by spinning from superacids, and the continuous production of macroscopic fiber from liquid crystalline graphene oxide. -
Characterization and influence of shear flow on the surface resistivity and mixing condition on the dispersion quality of multi-walled carbon nanotube/polycarbonate nanocomposites
Young Sil Lee, Kwan Han Yoon 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 3 86-92 (7 pages)
Multi-walled carbon nanotube (MWCNT)/polycarbonate (PC) nanocomposite was prepared by direct melt mixing to investigate the effect of the shear rate on the surface resistivity of the nanocomposites. In this study, an experiment was carried out to observe the shear induced orientation of the MWCNT in the polymer matrix using a very simple melt flow indexer with various loads. The compression-molded, should be eliminated. MWCNT/PC nanocomposite sample exhibited lower percolation thresholds (at 0.8...
