In this study, the fracture behavior of a thermoplastic-modified epoxy resin reinforced with continuous carbon fibers for two levels of fiber-matrix adhesion was performed. A carbon fiber with commercial sizing was used and also treated with a known silane, (3-glycidoxy propyl trimethoxysilane) coupling agent. Toughness was determined using the double cantilever test, together with surface analysis after failure using scanning electron microscope. The presence of polysulfone particles improved... -

In recent decades, there has been an increasing interest in the use of carbon fiber reinforced plastic (CFRP) in aerospace, renewable energy and other industries, due to its low weight and relatively good mechanical properties compared with traditional metals. However, due to the high cost of petroleum-based precursors and their associated processing costs, CF remains a specialty product and as such has been limited to use in high-end aerospace, sporting goods, automotive, and specialist... -

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... -
Computer-Aided Drug Discovery in Plant Pathology
한국식물병리학회 The Plant Pathology Journal 14 Pages
한국식물병리학회 The Plant Pathology Journal 2017, 33권 6호 1 529-542 (14 pages)
Control of plant diseases is largely dependent on use of agrochemicals. However, there are widening gaps between our knowledge on plant diseases gained from genetic/mechanistic studies and rapid translation of the knowledge into target-oriented development of effective agrochemicals. Here we propose that the time is ripe for computer-aided drug discovery/design (CADD) in molecular plant pathology. CADD has played a pivotal role in development of medically important molecules over the last three... -
Evaluation of Ash Deposition Behavior and Fine Particle Formation from Combustion of Low-rank Coal Impregnated with Molasses in DTF
Zi-Xiang Xu, Joo-Chang Park, Hyung-Taek Kim 한국열환경공학회 열환경공학 9 Pages
한국열환경공학회 열환경공학 2019, 제 14권 2호 6 40-48 (9 pages)
In recent years, many countries have invested enormous efforts to tackle increasingly harsh environmental problems, especially the greenhouse effect. The addition of biomass into coal is regarded as a promising technology to mitigate CO2 emissions. However, the costs related to retrofitting injection systems and unstable combustion inhibit this option. Therefore, this thesis developed a two-in-one fuel that impregnates molasses into the holes of low-rank coal(LRC), which can be directly applied... -

This study synthesized pure anatase carbon doped TiO₂ photocatalysts supported on a stainless steel mesh using a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide (DMF)/TiCl₄. The influence of the pyrolysis temperature and holding time on the morphological characteristics, particle sizes and surface area of the prepared catalyst was investigated. The prepared catalysts were characterized by several analytical methods: high resolution scanning electron microscopy (HRSEM), energy... -
Biocomposite membranes based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and multiwall carbon nanotubes for gas separation
Mongyoung Huh, Hye Min Lee, Young Soo Park, Seok Il Yun 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 17 116-121 (6 pages)
The development of gas separation membranes is currently an active research area because of the rapidly increasing interest in carbon dioxide capture and hydrogen recovery, which are two of the most important solutions for problems related to energy and the environment [1-4]. Polymer membranes show selectivity in the separation of gases due to differences in the permeability of individual gases through the polymer film [3,4]. Even though advantageous in terms of low cost, the segmental... -

한국탄소학회 Carbon Letters 2017, Vol.21 8 68-73 (6 pages)
We have demonstrated the production of thin films containing multilayer graphene-coated copper nanoparticles (MGCNs) by a commercial electrodeposition method. The MGCNs were produced by electrical wire explosion, an easily applied technique for creating hybrid metal nanoparticles. The nanoparticles had average diameters of 10?120 nm and quasispherical morphologies. We made a complex-electrodeposited copper thin film (CETF) with a thickness of 4.8 μm by adding 300 ppm MGCNs to the electrolyte... -
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... -
