J.I.KIM, I.S.Oh, H.J.Joo 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2001, Vol.2 No.1 5 27-36 (10 pages)
21세기에는 에너지의 고갈과 더불어 고도로 발달한 산업환경으로 인하여 재료의 경량화, 고성능화가 촉진되고 있다. 또한 우주산업과 운송산업은 방송, 통신산업과 더불어 가장 크게 성장할 것으로 예측된다. 이러한 우주산업의 재료들과 초고속 운송시스켐의 재료들이 CFRC가 내열, 구조재료로서 각광을 받고 있다[1-4].그러나 탄소재료는 500\'C 정도의 낮은 온도에서 산소와 급격히 반응하여 burn-off되는 심각한 결전을 가지고 있으므로 CFRC를 산화환겨에서 사용하기 위해서 수많은 연구가 수행되었다[5-8]. -

$CeO_2$에 담지된 구리산화물에서 벤젠의 촉매연소 반응에 대해 연구하였다. 담지된 구리산화물 촉매들은 볼밀법과 함침법으로 제조하였고, XRD, FT-IR, TEM 및 TPR에 의해 특성분석을 하였다. 볼밀법으로 제조된 CuO/$CeO_2$ 촉매는 높은 담지량에서도 잘 분산된 CuO를 얻었다. 볼밀법으로 제조된 CuO/$CeO_2$ 촉매는 함침법으로 제조된 촉매에 비해 높은 활성을 보여주었다. CuO의 담지량이 증가할수록 촉매 활성이 증가하였으며, 10 wt%로 담지된 촉매에서 가장 높은 활성을 나타내었다. 또한, 10 wt% CuO/$CeO_2$ 촉매에 소량의... -

The effect of NaCl plus 3% chitosan on the systolic blood pressure of spontaneously hypertensive rats (SHR) were evaluated and compared with NaCl plus KCl (NaCl, 49.36% + KCl 49.36%) and chitosan or NaCl treatment alone. In SHR, administration of NaCl plus chitosan (44 mM Na/day) for two months significantly decreased the systolic blood pressure greater than of NaCl plus KCl and NaCl alone. NaCl plus chitosan resulted, though not statistically significant, in decreased urinary Na excretion and... -

한국식물병리학회 The Plant Pathology Journal 14 Pages
한국식물병리학회 The Plant Pathology Journal 2012, 28권 2호 1 123-136 (14 pages)
Diseases caused by begomoviruses (family Geminiviridae, genus Begomovirus) constitute a serious constraint to tropical and sub-tropical agro-ecosystems worldwide. In recent years, they have also introduced in temperate regions of the world where they have great impact and are posing a serious threat to a variety of greenhouse crops. Begomoviral diseases can in extreme cases reduce yields to zero leading to catastrophic losses in agriculture. They are still evolving and pose a serious threat to... -
Resin Flow, Symptom Development, and Lignin Biosynthesis of Two Pine Species in Response to Wounding and Inoculation with Fusarium circinatum
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 4호 14 394-401 (8 pages)
Resin flow, symptom development, and lignin biosynthesis in response to wounding and fungal inoculation were investigated in Pinus rigida and Pinus densiflora. The two-year-old seedling stems were subjected to three types of treatments: (i) wounding without inoculation, (ii) wound-inoculation with a conidial suspension of Fusarium circinatum, and (iii) pre-wounding woundinoculation with the fungus 20 days after the initial wounding. Resin flow from wounding sites was more evident in P. rigida... -

한국탄소학회 Carbon Letters 2016, Vol.19 3 23-31 (9 pages)
Carbon rich fly ash was recently reported to have compositions that are ideal for use as a precursor and catalyst for carbon nanotube growth. This fly ash powder is mostly composed of pure carbon, predominantly present as sp2. In this work, the effect of sonication time on the morphology and structural properties of carbon rich fly ash particles is reported. The obtained results show that ultrasound treatment is an effective tool for producing ultrafine particles/fragments with higher porosity,...
