Strategy for Establish an Effective Mid-stream Supply Chain of Natural Gas Hydrate with Low Energy Consumption Type Container Carrier

Kagn H.J., Shin M-S, Korea Research Institute of Ships and Ocean Engineering (KRISO), KR

A number of countries and institutions are attempting to develop Natural Gas Hydrate (henceforth NGH) related technologies since NGH serves economic feasibility for mid-size gas-field development. However, there are several technical, economic and procedural problems [...]

Preparation of ion group functionalized diblock copolymers and examination of their thermogelling properties

Lee B.K., Kwon D.Y., Kwon J.S., Park J.H., Kwon D.Y., Kwon J.S., Kim J.H., Kim M.S., Oh S.H., Kim J.H., Kim M.S., Ajou University, KR

To investigate thermogelling behavior, in this study, methoxy polyethylene glycol-b-[poly(ε-caprolactone)-ran-poly(6-chloride-ε-caprolactone) (PCL-ran-PfCL)] (PCL-Cl) diblock copolymers were designed such that the PfCL content in the PCL segment was varied. The PCL-Cl diblock copolymers were derivatized by introducing [...]

Relationship between Morphology and Electrochemical Properties of Polyaniline in the Nanometer Regime

Lee Y., Yoon H., Chonnam National University, KR

Polyaniline (PANI) has found a wide range of applications due to its electrical properties, reversible redox behaviors and environmental stability. Here, we report the preparation of PANI nanostructures with three different aspect ratios, namely, nanospheres, [...]

Kinetically Controlled Formation of Deposited Polymer Nanomaterials with Unique Surface Substructures

Choi H., Yoon H., Chonnam National University, KR

One-dimensional (1D) electronic materials with inherent nanoscale features are considered to be promising components for achieving unprecedented future technologies. Much effort has been devoted to the synthesis of inorganic nanomaterials and, as a result, unique [...]

Conjugated Polymer Papers for Metal Ion Detection

Ahn K-J, Yoon H., Chonnam National University, KR

It is of great importance to detect heavy metal ion in solution. Here, we describe the electrochemical detection of metal ions using polypyrrole/cellulose (PPCL) composite papers in both static and flow systems. A home-made electrochemical [...]

Conducting Polymer Based Adhesives for Electrochemical Applications

Choi H., Yoon H., Chonnam National University, KR

There has been huge demand for developing advanced materials and devices for enhanced energy storage. However, relatively little attention has been devoted so far to the development of efficient binders for electrode materials. In this [...]

Thermal conductivity model for polymer/Boron Nitride nanocomposite considering air void content

Park S.Y., Kim J.H., Shin M.W., Yonsei University, KR

Polymer/Boron Nitride (BN) nanocomposite is promising interfacial material for cooling of electronic systems. It is important to determine percolation threshold when it practically uses in the industry. But, the exact prediction with existing model is [...]

Preparation of a Flexible Microfluidic Chip Device with MMT/PEG Hydrogel Nanocomposite Molds for Nanobio-chip Applications

Kim G.M., Kim Y.H., Woo Y., Jung J., Choi J-R, Kim G.M., Kim Y.H., Kang B.K., Sohn J-W, Daegu-Gyeongbuk Medical Innovation Foundation, KR

A thin and flexible microfluidic chip device using microstructured montmorillonite (MMT) reinforced polyethylene glycol (PEG) nanocomposite molds has been presented to apply miniaturized nanobio-chips. Biocompatible PEG hydrogel with 1-2 wt.% of MMT was used to [...]

Core-shell Silica-coated Iron Oxide Nanoparticles for Magnetic Hyperthermia

Iqbal Y., Bae H., Hong S., Rhee I., Kyungpook National University, KR

We report the synthesis and characterization of silica-coated iron oxide nanoparticles with a core-shell structure for magnetic hyperthermia. The nanoparticles of silica-coated iron oxide were synthesized using the reverse micelle method. The coating of the [...]

Morphology and Size Control of Mesoporous ORMOSIL Particles

Jung G.I., Kim J-S, Koo S.M., Hanyang University, KR

Mesoporous ORMOSIL particles with tailored morphology and/or controlled size were prepared by a simple two-step process. The first step, synthesis of monodisperse ORMOSIL particles with multi-layered structure, involved a one-pot process in an aqueous solution [...]
