한국탄소학회 Carbon Letters 2017, Vol.22 2 14-24 (11 pages)
the pseudo-second-order kinetic model for both methods. In addition, the adsorption isotherms of picric acid from aqueous solutions on the MWCNTs were investigated using six two-parameter models (Langmuir, Freundlich, Tempkin, Halsey, Harkins-Jura, Fowler- Guggenheim), four three-parameter models (Redlich-Peterson, Khan, Radke-Prausnitz, and Toth), two four-parameter equations (Fritz-Schlunder and Baudu) and one five-parameter equation (Fritz-Schlunder). Three error analysis methods, correlation... -
Detection of Clavibacter michiganensis subsp. michiganensis Assisted by Micro- Raman Spectroscopy under Laboratory Conditions
Moisé, s Roberto Vallejo Pé, rez, Hugo Ricardo Navarro Contreras, Jesú, s A. Sosa Herrera, José, Pablo Lara Á, vila 한국식물병리학회 The Plant Pathology Journal 12 Pages

Clavibacter michiganensis subsp. michiganesis (Cmm) is a quarantine-worthy pest in México. The implementation and validation of new technologies is necessary to reduce the time for bacterial detection in laboratory conditions and Raman spectroscopy is an ambitious technology that has all of the features needed to characterize and identify bacteria. Under controlled conditions a contagion process was induced with Cmm, the disease epidemiology was monitored. Micro-Raman spectroscopy (532 nm... -
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. -
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... -

최근 기후변화로 인하여 태풍 및 집중호우로 인한 극한 강우사상의 발생빈도가 증가하고 있으며, 급격한 도시화로 인한 유역 내 불투수 면적이 늘어나고 있다. 이로 인해 재산피해가 증가하고 있어 기후변화를 고려한 미래 하천범람 등 홍수피해를 경감시키기 위한 홍수저감 대안 선정이 필요하다. 따라서 본 연구에서는 기후변화를 고려하여 목표기간별로(기준년도 : 1971∼2010년, 목표기간Ⅰ : 2011∼2040년, 목표기간Ⅱ : 2041∼2070년, 목표기간Ⅲ : 2071∼2100년) HEC-HMS모형 을 이용하여 기후변화에 따른 홍수량을 산정하였다.... -

Waymire 등 (1984)에 의해 제안된 다차원 강우모형을 시공간 상에서 강우를 모의하기 위하여 사용하였다. 위 모형은 시공간 상에서 실제 중규모 호우의 기상학적인 특징을 잘 재현하면서 이동하는 호우를 모의한다. 영월 지역의 4개 지점에서 4년간의 7월 강우 시자료를 바탕으로 모형의 매개변수를 추정하였으며, 추정된 매개변수를 사용하여 12년간의 7월 강우를 1시간 간격으로 모의 발생하였다. 모의 발생된 자료를 각 지점별로 재 구축한 후, 각 지점별 1, 2차 통계량의 계산을 통하여 Neyman-Scott 일차원 강우모형의 매개변수를... -
Carbon nanotubes synthesis using diffusion and premixed flame methods: a review
Garima Mittal, Vivek Dhand, Kyong Yop Rhee, Hyeon-Ju Kim and Dong Ho Jung 한국탄소학회 Carbon Letters 10 Pages

In recent years, flame synthesis has absorbed a great deal of attention as a combustion method for the production of metal oxide nanoparticles, carbon nanotubes, and other related carbon nanostructures, over the existing conventional methods. Flame synthesis is an energyefficient, scalable, cost-effective, rapid and continuous process, where flame provides the necessary chemical species for the nucleation of carbon structures (feed stock or precursor) and the energy for the production of carbon...
