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)
sulfate functional groups introduced during the manufacturing process. In addition, pyrolyzed CNPs (CCNPs) showed more effective chemical activation behavior compared with MCC-induced carbonaceous materials. The activated CCNPs exhibited a microporous carbon structure with a high surface area of 1310.6 m2/g and numerous oxygen heteroatoms. The results of this study show the effects of morphology and the surface properties of cellulose-based nanomaterials on pyrolysis and the activation process. -
Adsorption Behaviors of Noxious Gases On Chemically Surface-terated Activated Carbons
Soo-Jin Park, Jun-Sik Shin 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2003, Vol.4 No.1 6 31-35 (5 pages)
20세기는 과학기술 발달이 꾸준히 발전한 시대였으며 이와병행하여 전쟁의 양상 및 무기의 체계에 커다란 혁명을 가져왔다. 특히, 최근 문제가 되고 있으며 가난한 나라의 핵무기로 비유되는 생화학 무기는 값싸게 제작할 수 있고, 이를 소지한 채 잠입하며 살포할 수 있으며, 무색,무취하며 탐지하기가 어렵고, 극미량으로도 인간에게 해를 끼칠 수 있을 뿐 아니라 한번 오염되면 스스로 번식 확산하기 때문에 인류에 막대한 피해를 야기할 수 있어 그 심각성은 일반의 예상을 뛰어 넘는다. -

NO gas sensing ability of activated carbon fibers modified by an electron beam for improvement in the surface functional group
Mi-Seon Park, Sangmin Lee, Min-Jung Jung, Hyeong Gi Kim, Young-Seak Lee 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 3 19-25 (7 pages)
Activated carbon fiber (ACF) surfaces are modified using an electron beam under different aqueous solutions to improve the NO gas sensitivity of a gas sensor based on ACFs. The oxygen functional group on the ACF surface is changed, resulting in an increase of the number of non-carbonyl (-C-O-C-) groups from 32.5% for pristine ACFs to 39.53% and 41.75% for ACFs treated with hydrogen peroxide and potassium hydroxide solutions, respectively. We discover that the NO gas sensitivity of the gas sensor... -
Effect of surface modification of carbon felts on capacitive deionization for desalination
Jong-Ho Lee, Hong-Joo Ahn, Donghwan Cho, Jeong-Il Youn, Young-Jig Kim, Han-Jun Oh 한국탄소학회 Carbon Letters 8 Pages

respectively. The potassium hydroxide (KOH) modified carbon felt exhibited high Brunauer-Emmett-Teller (BET) surface areas and large pore volume, and oxygencontaining functional groups were increased during KOH chemical modification. However, the BET surface area significantly decreased by nitric acid (HNO3) chemical modification due to severe chemical dissolution of the pore structure. The capability of electrosorption by an electrical double-layer and the efficiency of capacitive deionization... -
Role of Angiotensin II and Nitric Oxide in the Rat Paraventricular Nucleus
Eun-KyoungYang 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 6 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2001, Vol.5 No.1 6 41-46 (6 pages)
To investigate the mutual relationship between angiotensin II (Ang II) and nitric oxide (NO) in paraventricular nucleus (PVN), Ang II receptor type Ia (AT1A), type Ib (AT1B), endothelial constitutive nitric oxide synthase (ecNOS), and neuronal constitutive nitric oxide synthase (ncNOS) mRNA levels of rat PVN were measured after unilateral carotid artery ligation. AT1A and AT1B mRNA levels were markedly elevated 6 hrs after unilateral carotid artery ligation. Losartan injection (10μg/0.3μl)... -
Two Types of Voltage-dependent Outward Potassium Currents in Smooth Muscle Cells of Rabbit Basilar Atery
TongMookKang, InsukSo, DaeYongUhm, KiWhanKim 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 15 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 1997, Vol.1 No.2 7 169-183 (15 pages)
We have investigated the two types of voltage-dependent outward potassium (K) currents, i.e. delayed rectifier K current (IK(V)) and 'A-like' transient outward K current (Ito) with patch-clamp technique in single smooth muscle cells (SMCs) isolated from rabbit basilar artery, and investigated the characteristics of them. The time-courses of activation were well fitted by exponential function raised to second power (n2) in IK(v) and fourth power (n4) in Ito. The activation, inactivation and...
