파주 혜음원지 출토 목기 부착 직물에 관한 연구
채정민, 유효선 한국대학박물관협회 고문화 21 Pages
한국대학박물관협회 고문화 2013, 제82집 5 113-133 (21 pages)
본 연구는 파주 혜음원지에서 출토된 목기에 사용된 직물에 대한 감별과 섬유의 퇴화 현상에 대한 섬유 특성을 조사한 것이다. 연구 결과 네 가지 목기에 사용된 직물은 모두 평직물로 sample 1, sample 2, sample 4는 면섬유로 조사되었으며 sample 3에서는 면섬유와 마섬유가 모두 관찰되었다. 시료는 섬유 고유의 성질을 대부분 잃어버렸으며 섬유의 측면과 단면에서 심각한 손상 모습이 관찰되었고 섬유의 결정화도가 매우 낮은 것으로 조사되었다. 이 결과는 다른 자연 퇴화된 섬유 유물에 대한 결과와 비교함으로써 고섬유의 퇴화... -
Three-dimensional porous graphene materials for environmental applications
Muruganantham Rethinasabapathy, Sung-Min Kang, Sung-Chan Jang, Yun Suk Huh 한국탄소학회 Carbon Letters 13 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 1 1-13 (13 pages)
Porous materials play 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... -
Preparation of gold nanoparticle/single-walled carbon nanotube nanohybrids using biologically programmed peptide for application of flexible transparent conducting films
MinHo Yang, Bong Gill Choi 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 4 26-31 (6 pages)
one-dimensional (1D) arrangement of Au nanoparticles on single-walled carbon nanotubes (SWNTs) using biologically programmed peptides as structure-guiding 1D templates. The peptides were designed by the combination of glutamic acid (E), glycine (G), and phenylalanine (F) amino acids; peptides efficiently debundled and exfoliated the SWNTs for stability of the dispersion and guided the growth of the array of Au nanoparticles in a controllable manner. Moreover, we demonstrated the superior ability... -
Adsorption of lisinopril and chlorpheniramine from aqueous solution on dehydrated and activated carbons
El-Said I. El-Shafey, Haider A. J. Al-Lawati, Wafa S. H. Al-Saidi 한국탄소학회 Carbon Letters 11 Pages

Date palm leaflets were used as a precursor to prepare dehydrated carbon (DC) via phosphoric acid treatment at 150°C. DC, acidified with H3PO4, was converted to activated carbon (AC) at 500°C under a nitrogen atmosphere. DC shows very low surface area (6.1 m2/g) while AC possesses very high surface area (829 m2/g). The removal of lisinopril (LIS) and chlorpheniramine (CP) from an aqueous solution was tested at different pH, contact time, concentration, and temperature on both carbons. The... -
A review: role of interfacial adhesion between carbon blacks and elastomeric materials
Min-Joo Kang, Young-Jung Heo, Fan-Long Jin, Soo-Jin Park 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2016, Vol.18 1 1-10 (10 pages)
Carbon blacks (CBs) have been widely used as reinforcing materials in advanced rubber composites. The mechanical properties of CB-reinforced rubber composites are mostly controlled by the extent of interfacial adhesion between the CBs and the rubber. Surface treatments are generally performed on CBs to introduce chemical functional groups on its surface. In this study, we review the effects of various surface treatment methods for CBs. In addition, the preparation and properties of CB-reinforced... -
