Doh Gyu Hwang, Euigyung Jeong, Seung Geol Lee 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 13 81-85 (5 pages)
proposed and studied to remove greenhouse gases from the atmosphere and protect the environment [3,4]. Carbon-based materials for adsorption are an intriguing subject owing to their very high specific surface area, low weight, and elasticity [5,6]. Among various carbonaceous materials, graphene has attracted much attention from researchers for these reasons; consequently, this material has been empirically and theoretically investigated for possible applications, such as gas sensors [7-10]. -

This study surveys the improvement characteristics in old-aged muscular mitochondria by bio-active materials coated fabric (BMCF). To observe the effects, the fabric (10 and 30%) was worn to old-aged rat then the oxygen consumption efficiency and copy numbers of mitochondria, and mRNA expression of apoptosis- and mitophagy-related genes were verified. By wearing the BMCF, the oxidative respiration significantly increased when using the 30% materials coated fabric. The mitochondrial DNA copy... -

mapping technique. X-ray diffraction and thermal gravimetric analysis veri?ed the presence of GO and Ag in the bicomposite nano?brous mats. Antibacterial tests against Escherichia coli demonstrated that the addition of GO and Ag-RGO to the PU nano?ber greatly enhanced bactericidal efficiency. Overall, these features of the synthesized nano?bers make them a promising candidate material in the biomedical field for applications such as tissue engineering, wound healing, and drug delivery systems. -
Adsorption characteristics of heavy metals ions by physical activation on coal tar pitch-based activated carbon fibers
Bo-kyung Choi, Jae-Kyoung Ko, Soo-Jin Park, Min-Kang Seo 한국탄소학회 Carbon Letters 5 Pages

Due to the increasing population growth of modern society, along with rapid industrial development and urbanization, environmental pollution continues to worsen and has become an important issue, not only domestically but also worldwide. In particular, toxic substances such as heavy metal ions are present in the wastewater produced by various industries. This wastewater flows into rivers, pollutes water supplies, and can contaminate the drinking water supplied to people [1-3]. Powder or... -
Three-dimensional porous graphene materials for environmental applications

a vital role in science and technology. The ability to control their pore structures at the atomic, molecular, and nanometer scales enable interactions with atoms, ions and molecules to occur throughout the bulk of the material, for practical applications. Three-dimensional (3D) porous carbon-based materials (e.g., graphene aerogels/hydrogels, sponges and foams) made of graphene or graphene oxide-based networks have attracted considerable attention because they offer low density, high porosity,... -
Adsorption capability of activated carbon synthesized from coconut shell

perfect crystallite structure. The field emission scanning electron microscopy image showed the presence of well-developed pores on the surface of the activated carbon. The presence of important functional groups was shown by the Fourier transform infrared spectroscopy spectrum. The adsorption of methyl orange onto the activated carbon reached 100% after 12 min. Kinetic analysis indicated that the adsorption of methyl orange solution by the activated carbon followed a pseudo-second-order kinetic... -
