The electrical and heating properties of copper-incorporated graphite fibers fabricated using different ultrasonication techniques
Kyeong Min Lee, Min-Ji Kim, Hanjoo Jo, Sang Young Yeo, Young-Seak Lee 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 15 111-114 (4 pages)
Electrical energy can be converted into heat energy through ohmic joule heating. Metallic materials are typically used in electrical heating elements because of their great electrical conductivity. However, metallic materials have several weaknesses, such as corrosion susceptibility, heavy weight, high manufacturing costs, and electromagnetic wave emissions [1,2]. To resolve these problems, carbon materials with good electrical conductivity, such as carbon fibers, graphite fibers, carbon... -
Physicochemical properties and methane adsorption performance of activated carbon nanofibers with different types of metal oxides
Faten Ermala Che Othman, Norhaniza Yusof, Hasrinah Hasbullah, Juhana Jaafar, Ahmad Fauzi Ismail, Noor Shawal Nasri 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 11 82-89 (8 pages)
In this study, composite PAN-based ACNFs embedded with MgO and MnO2 were prepared by the electrospinning method. The resultant pristine ACNFs, ACNF/MgO and ACNF/MnO2 were characterized in terms of their morphological changes, SSA, crystallinity and functional group with FESEM-EDX, the BET method, XRD and FTIR analysis, respectively. Results from this study showed that the SSA of the ACNF/MgO composite (1893 m2 g?1) is significantly higher than that of the pristine ACNFs and ACNF/MnO2 which is... -
Relationships between dielectric properties and characteristics of impregnated and activated samples of potassium carbonate- and sodium hydroxide-modified palm kernel shell for microwave-assisted activation
Norulaina Alias, Muhammad Abbas Ahmad Zaini, Mohd Johari Kamaruddin 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 9 62-72 (11 pages)
The aim of this work was to evaluate the dielectric properties of impregnated and activated palm kernel shells (PKSs) samples using two activating agents, potassium carbonate (K2CO3) and sodium hydroxide (NaOH), at three impregnation ratios. The materials were characterized by moisture content, carbon content, ash content, thermal profile and functional groups. The dielectric properties were examined using an open-ended coaxial probe method at various microwave frequencies (1?6 GHz) and... -
A modified electrode by a facile green preparation of reduced graphene oxide utilizing olive leaves extract
Abeer Baioun, Hassan Kellawi, Ahamed Falah 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 7 47-54 (8 pages)
Different phytochemicals obtained from various natural plant sources are used as reduction agents for preparing gold, copper, silver and platinum nanoparticles. In this work a green method of reducing graphene oxide (rGO) by an inexpensive, effective and scalable method using olive leaf aqueous extract as the reducing agent, was used to produce rGO. Both GO and rGO were prepared and investigated by ultraviolet and visible spectroscopy, Fourier-transform infrared, scanning electron microscopy,... -
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... -

Lyocell-based activated carbon fibers improved the adsorption of harmful gas properties when produced via dual-simultaneous treatments
Byong Chol Bai, Ji Sun Im, Young-Seak Lee 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2017, Vol.23 10 69-73 (5 pages)
In gas adsorption processes, activated carbon fibers (ACFs) are used for the adsorption of the harmful gases that are generated by coal or oil combustion, and they have been widely studied [1,2]. ACFs have been used for harmful gas removal because of their specific surface area, micropores, reproducibility, safety, and processing ability, which are beneficial properties for a wide range of applications [3,4]. -
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...
