Activated carbons prepared from mixtures of coal tar pitch and petroleum pitch and their electrochemical performance as electrode materials for electric double-layer capacitor
Eunji Lee, Soon Hyung Kwon, Poo Reum Choi, Ji Chul Jung, Myung-Soo Kim 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 2 78-85 (8 pages)
Activated carbons (ACs) were prepared by activation of coal tar pitch (CTP) in the range of 700°C-1000°C for 1-4 h using potassium hydroxide (KOH) powder as the activation agent. The optimal activation conditions were determined to be a CTP/KOH ratio of 1:4, activation temperature of 900°C, and activation time of 3 h. The obtained ACs showed increased pore size distribution in the range of 1 to 2 nm and the highest specific capacitance of 122 F/g in a two-electrode system with an organic... -
Reduction of long-term potentiation at Schaffer collateral-CA1 synapses in the rat hippocampus at the acute stage of vestibular compensation
GyoungWanLee, JaeHyoKim, MinSunKim 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 6 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2017, Vol.21 No.4 8 423-428 (6 pages)
Vestibular compensation is a recovery process from vestibular symptoms over time after unilateral loss of peripheral vestibular end organs. The aim of the present study was to observe time-dependent changes in long-term potentiation (LTP) at Schaffer collateral-CA1 synapses in the CA1 area of the hippocampus during vestibular compensation. The input-output (I/O) relationships of fEPSP amplitudes and LTP induced by theta burst stimulation to Schaffer’s collateral commissural fibers were... -
Spatial reproducibility of complex fractionated atrial electrogram depending on the direction and configuration of bipolar electrodes: an in-silico modeling study
Jun-SeopSong, Young-SeonLee, MinkiHwang, Jung-KeeLee, ChangyongLi, BoyoungJoung, Moon-HyoungLee, EunBoShim, Hui-NamPak 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages

a virtual bipolar conventional catheter (conv-cath: size 3.5 mm, inter-electrode distance 4.75 mm). Additionally, the spatial correlations of CFAE-CLs and the percentage of consistent sites with CFAECL<120 ms were analyzed. The results from the conv-cath were compared with that obtained using a mini catheter (mini-cath: size 1 mm, inter-electrode distance 2.5mm). Depending on the catheter orientation, the electrogram morphology and CFAE-CLs varied (conv-cath: 11.5±0.7% variation, mini-cath:... -
The advantage of topographic prominence-adopted filter for the detection of short-latency spikes of retinal ganglion cells

600-800, 800-1000 μm). Fifty cathodic phase-1st biphasic current pulses (duration 500 μs, intensity 5, 10, 20, 30, 40, 50, 60 μA) were applied at every 1 sec. We compared false positive error and false negative error in FB filter and TP-adopted FB filter. By implementing TP-adopted FB filter, short-latency spike can be detected better regarding sensitivity and specificity for detecting spikes regardless of the strength of stimulus and the distance between stimulus and recording electrodes. -
Effect of repetitive wrist extension with electromyography-triggered stimulation after stroke
Yo-seb Lee, Yu-ri Cha, Young Kim, Su-jin Hwang, Yi-jung Chung 물리치료재활과학회 Physical Therapy Rehabilitation Science 7 Pages
물리치료재활과학회 Physical Therapy Rehabilitation Science 2017, 제 6권 제 3호 4 127-133 (7 pages)
Objective: The purpose of this study was to explore the effect of repetitive wrist extension task training with electromyography (EMG)-triggered neuromuscular electrical stimulation (NMES) for wrist extensor muscle recovery in patients with stroke. Design: Randomized controlled trial. Methods: Fifteen subjects who had suffered a stroke were randomly assigned to an EMG-triggered NMES group (n=8) or control group (n=7); subjects in both groups received conventional therapy as usual. Subjects in... -
Mechanical properties of epoxy composites reinforced with ammonia-treated graphene oxides
Mi-Seon Park, Sangmin Lee, Young-Seak Lee 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 1 1-7 (7 pages)
The effects of ammonia-treated graphene oxide (GO) on composites based on epoxy resin were investigated. Ammonia solutions of different concentrations (14?28%) were used to modify GO. Nitrogen functional groups were introduced on the GO surfaces without significant structural changes. The ammonia-treated GO-based epoxy composites exhibited interesting changes in their mechanical properties related to the presence of nitrogen functional groups, particularly amine (C-NH2) groups on the GO... -
Carbon-allotropes: synthesis methods, applications and future perspectives
P. S. Karthik, A. L. Himaja and Surya Prakash Singh 한국탄소학회 Carbon Letters 19 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.4 1 219-237 (19 pages)
The element carbon has been used as a source of energy for the past few hundred years, and now in this era of technology, carbon has played a significant and very prominent role in almost all fields of science and technology. So as an honour to this marvellous element, we humans should know about its various forms of existence. In this review article, we shed light on all possible carbon-allotropes; similarities in their synthesis techniques and the starting materials; their wide range of... -
Superhydrophobic carbon-based materials: a review of synthesis, structure, and applications
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...
