The present study was designed to evaluate effects of intermittent electrical stimulation of the sciatic nerve on the atrophic response of antigravity muscles, such as the soleus (slow m.) and medial gastrocnemius (fast m.) muscles. Rats (Sprague-Dawley, 245-255g) were subjected to a hindlimb suspension and divided into three groups : one was with hindlimb suspension (MS) and another with hindlimb suspension plus intermittent electrical stimulation of the sciatic nerve (HS ES). Control group... -

We studied the basic properties and fabrication of reduced graphene oxide (rGO) prepared using eco-friendly reduction agents in the graphene solution process. Hydrazine is generally used to reduce graphene oxide (GO), which results in polluting emissions as well as fixed nitrogen functional groups on different defects in the graphene sheets. To replace hydrazine, we developed eco-friendly reduction agents with similar or better reducing properties, and selected of them for further analysis. In... -
NO gas sensing ability of activated carbon fibers modified by an electron beam for improvement in the surface functional group

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 fabricated using the modified ACFs as an electrode material is increased, although the specific surface area of the ACFs is decreased because of the recovery of their crystal structure. This is attributed to the static electric interaction between NO gas and the non-carbonyl groups introduced... -
Waste coffee grounds-derived nanoporous carbon nanosheets for supercapacitors
Min Hong Park, Young Soo Yun, Se Youn Cho, Na Rae Kim, Hyoung-Joon Jin 한국탄소학회 Carbon Letters 6 Pages

The development of nanostructured functional materials derived from biomass and/or waste is of growing importance for creating sustainable energy-storage systems. In this study, nanoporous carbonaceous materials containing numerous heteroatoms were fabricated from waste coffee grounds using a top-down process via simple heating with KOH. The nanoporous carbon nanosheets exhibited notable material properties such as high specific surface area (1960.1 m2 g?1), numerous redox-active heteroatoms... -

독스핀 하이드로클로라이드 선택전극의 구조와 성능특징에 대하여 개발하였다. 전극의 3가지 형태가 있다. I. 플라스틱 막 II. 코팅된 선형 III. 흑연으로 된 로드, 이것들은 암모늄 라이네케이트를 갖는 독스핀 하이드로클로라이드의 결합에 기초하여 구성되었다. 막의 조성, 가소제의 종류, 시험용액의 pH, 담궈 놓은 시간 그리고 전극에 있는 이질 이온들의 영향을 조사했다. $25^{circ}C$에서 전극 I, II, III에 대해 각각 57.41 ${pm}$ 0.5, 56.22 ${pm}$ 0.2 and 52.88 ${pm}$ 0.7 mV 의 평균 보정 그래프 기울기를 갖는 Nernst...
