Hye-Min Lee, Kay-Hyeok An, Byung-Joo Kim 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.2 13 146-150 (5 pages)
In this work, activated carbon nanofiber (ACNF) electrodes with high double-layer capacitance and good rate capability were prepared from polyacrylonitrile nanofibers by optimizing the carbonization temperature prior to H2O activation. The morphology of the ACNFs was observed by scanning electron microscopy. The elemental composition was determined by analysis of X-ray photoelectron spectroscopy. N2-adsorption-isotherm characteristics at 77 K were confirmed by Brunauer-Emmett-Teller and... -

this study, synthetic viscose rayon fabric has been used for preparing activated carbon fabric (ACF), impregnated with different concentrations of H3PO4. The effect of H3PO4 impregnation on the weight yield, surface area, pore volume, chemical composition and morphology of ACF were studied. Experimental results revealed that both Brunauer-Emmett- Teller surface area and micropore volume increased with increasing H3PO4 concentration; however, the weight yield and microporosity (%) decreased. It... -

a glassy carbon electrode (GCE). The Fe3O4/GCE was utilized for sensing chloramphenicol (CAP) by cyclic voltammetry and square wave voltammetry. A reduction peak of CAP at the Fe3O4/GCE was observed at 0.62 V, whereas the uncoated GCE exhibited a very small response compared to that of the Fe3O4/GCE. The electrocatalytic ability of Fe3O4 was mainly attributed to the formation of Fe(VI) during the anodic scan, and its reduction to Fe(III) on the cathodic scan facilitated the sensing of CAP. The... -
Synthesis and characterization of carbon doped TiO₂ photocatalysts supported on stainless steel mesh by sol-gel method

suggested the substitution of titanium in TiO₂ by carbon. Instead of using calcination, PAN pyrolysis was used to control the carbon content, and the mesoporosity was tailored by the applied temperature. The supported TiO₂ nanocrystals prepared by pyrolysis at 300, 350, and 400ºC for 3 h on a stainless steel mesh were actual supported carbon doped TiO₂ nanocrystals. Thus, PAN/DMF/TiCl₄ offers a facile, robust sol-gel related route for preparing supported carbon doped TiO₂ nanocomposites. -
Removal of chromium from tannery wastewater by electrosorption on carbon prepared from peach stones: effect of applied potential

한국탄소학회 Carbon Letters 2017, Vol.21 10 81-85 (5 pages)
removal of chromium from tannery wastewater by electrosorption on carbon prepared from lignocellulosic natural residue "peach stones' thermally treated. The followed steps for obtaining coal in chronological order were: cleaning, drying, crushing and finally its carbonization at 900°C. The characterization of the carbon material resulted in properties comparable to those of many coals industrially manufactured. The study of the dynamic adsorption of chromium on the obtained material resulted in... -
Nanoporous carbon synthesized from grass for removal and recovery of hexavalent chromium

were synthesized by pyrolysis of grass as carbon precursor. The synthesized carbon has high surface area and pore volume. The carbon products were acid functionalized and characterized by Fourier transform infrared spectroscopy, X-ray diffraction, Brunauer?Emmett?Teller, transmission electron microscopy, and Energy Dispersive X-ray microanalysis. Acid functionalized nanoporous carbon was explored for use in removal of toxic Cr(VI) ions from aqueous media. An adsorption study was done as a... -

as an important green and economic technology. It is very important to develop highly efficient adsorbents to realize techno-economic systems for CH4 adsorption and storage. In this review, we summarize the nanomaterials being used for CH4 adsorption, which are divided into non-carbonaceous (e.g., zeolites, metal-organic frameworks, and porous polymers) and carbonaceous materials (e.g., activated carbons, ordered porous carbons, and activated carbon fibers), with a focus on recent research. -
Preparation and characterization of carbon fiber-reinforced thermosetting composites: a review
Fan-Long Jin, Soo-Jin Park 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 1 67-77 (11 pages)
Carbon fibers (CFs) have a unique combination of properties which allow them to be widely used as reinforcing materials in advanced polymer composites. The mechanical properties of CF-reinforced polymer composites are governed mainly by the quality of interfacial adhesion between the CFs and the polymer matrix. Surface treatments of CFs are generally carried out to introduce chemical functional groups on the fiber surfaces, which provide the ability to control the surface characteristics of CFs.... -

당뇨병성 신증은 만성 당뇨병에서 흔히 동반되는 심각한 합병증이나 그 발생기전은 확실히 밝혀져 있지 않다. 본 연구에서는 암, 노화, 염증등 여러 가지 질환의 발생에 관여한다고 알려진 산화성 스트레스의 증가가 당뇨병성 신증의 발생에 관여하는지를 알아 보았다. 쥐에서 신증의 유발을 용이하게 하기 위해 먼저 한쪽 신장을 적출한후 스트렙토조토신을 주사하여 당뇨병을 유발하였다(NEPH-STZ). 당뇨병 유발 8주후, NEPH-STZ쥐들은 심한 고혈당증, 단백뇨, 고혈압의 증상을 보였으며 신장조직은 보상성 비대와 함께...
