Histologic morphology and involucrin, filaggrin, and keratin expression in normal canine skin from dogs of different breeds and coat types
Sirin Theerawatanasirikul, Gunnaporn Suriyaphol, Roongroje Thanawongnuwech, Achariya Sailasuta* 대한수의학회 Journal of Veterinary Science 8 Pages
대한수의학회 Journal of Veterinary Science 2012, 제 13권 제 2호 7 163-170 (8 pages)
The purpose of this study was to measure the thickness of canine epidermis at various anatomical sites according to localization of cornified envelopes (involucrin and filaggrin), keratins (keratin 10, 5), and their mRNA expression. This was done in the skin of five breeds of dogs including seven poodles, six golden retrievers, six Shih Tzus, four pugs, and four Labrador retrievers. Epidermal thickness of the stratum corneum and nucleated epidermal layer was significantly different. The greatest... -
Improving dispersion of multi-walled carbon nanotubes and graphene using a common non-covalent modifier
Youbin Kwon, Wonbo Shim, Seung-Yeol Jeon, Ji-Ho Youk, Woong-Ryeol Yu 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 8 53-61 (9 pages)
The reportedly synergistic effects of carbon nanotubes (CNTs) and graphene hybrids have prompted strong demand for an efficient modifier to enhance their dispersion. Here, we investigated the ability of poly(acrylonitrile) (PAN) to overcome the van der Waals interaction of multi-walled CNTs (MWCNTs) and graphene by employing a simple wrapping process involving ultrasonication and subsequent centrifugation of PAN/MWCNT/graphene solutions. The physical wrapping of MWCNTs and graphene with PAN was... -
A review: synthesis and applications of graphene/chitosan nanocomposites
Hui Yuan, Long-Yue Meng, Soo-Jin Park 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2016, Vol.17 No.1 2 11-17 (7 pages)
Recently, with continuous developments in the field of materials science, graphene oxide (GO) has emerged as a promising material with excellent electrical, thermal, mechanical, and optical properties, which play important roles in most fields. Researchers have achieved considerable progress with graphene. Chitosan (CS) is a natural polymer that has been studied intensively owing to its specific formation, high chemical resistance, and excellent physical properties. These outstanding properties... -
Advances in liquid crystalline nano-carbon materials: preparation of nano-carbon based lyotropic liquid crystal and their fabrication of nano-carbon fibers with liquid crystalline spinning
Yong-Mun Choi, in Jung Jun Yeon, Hwang Seung Min, Kim Hyeonsu Jeong, Bon-Cheol Ku, Munju Goh 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.4 1 223-232 (10 pages)
This review presents current progress in the preparation methods of liquid crystalline nanocarbon materials and the liquid crystalline spinning method for producing nano-carbon fibers. In particular, we focus on the fabrication of liquid crystalline carbon nanotubes by spinning from superacids, and the continuous production of macroscopic fiber from liquid crystalline graphene oxide. -
Superhydrophobic carbon-based materials: a review of synthesis, structure, and applications
Long-Yue Meng, Soo-Jin Park 한국탄소학회 Carbon Letters 16 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.2 5 89-104 (16 pages)
Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as... -

발사체의 상단, 궤도선, 우주비행선 등의 추진기관은 불가피하게 무중력 환경에서 작동해야 한다. 이러한 비행체들이 겪는 비행 환경은 일반적인 중력장과 다르기 때문에 이에 대한 많은 연구들이 진행되어 왔다. 무중력 상태에서의 유체의 거동은 부착력, 응집력, 표면장력 등의 비중이 커지기 때문에 중력이 있는 상태에서와 다르게 나타난다. 본 논문에서는 무중력 환경에서 유체의 거동 특성에 대하여 알아보고 이런 유체의 거동 특성이 액체추진기관에 미치는 영향과 문제점에 대해 기술한다. 또한 이 문제점을 해결하기 위해 어떤... -

흡수된 nonionic dye 분자들은 결정상을 제외한 amorphous 부분이나 ionic aggregate 분근에 존재하는데, 주위 사슬의 극성에 따라 dispersion force (ethylene 사슬 부분), polar force (acid 부분), ionic dipole (ionic aggregate 부분)의 세 가지 다른 힘의 영향 아래 놓이게 된다. 극성이 적은 ethylene 사슬부분의 dispersion force 영향 아래에 존재하는 Nile Red의 UV/Vis 흡수피크는 500nm 부근에서, polar한 acid 그룹의 영향을 받는 dye 피크는 525 nm, 그리고 ionic aggregate의 영향에 의한 dye는 Na+-아이오노머의 경우 550...
