Synthesis of SiOx Nanowires at Low Temperatures Using Zn Catalyst

Choi C-S, Yoon J-H, Kangwon National University, KR

we report that the SiOx NWs can be synthesized by directly exposing Zn film to atomic oxygen and silicon plasma mixture produced by PECVD method using a mixture of SiH4 and N2O gas at temperatures [...]

Manufacturing and Properties of Nanofiber Composites

Yong D-K, Chungnam National University, KR

Recently, a fiber composite for various industrial applications including automotive, aerospace and civil engineering is in the spotlight as a specialized-functional material such as high strength and modulus, high thermal resistance and high elasticity etc. [...]

Viscosity Behavior of Magnetic Nanoparticle Filled Fluids and Impact Resistance of Their Fabric Composites

Lee S-G, Chungnam National University, KR

Ferromagnetic fluid(FMF) and magneto-rheological fluid(MRF) have been prepared from iron oxide and iron alloy nanoparticles, respectively, with a proper fluidic medium. In the FMF, chemically synthesized iron oxide particles having diameters of several nanometers were [...]

Extremely Stretchable Electrode based on Combination of Inkjet-Printed Silver and Conductive Composite for Stretchable Lighting Applications

Kim D., Kim S., Byun J., Chung S., Kim D., Kim S., Hong Y., Seoul National University, KR

We have studied stretchable electrode based on combination of inkjet-printed silver electrode and conductive composite materials for stretchable lighting device applications. Previous stretchable electrodes were mainly realized by either vacuum deposition or inkjet-printing of conductive [...]

Effect of γ-ray irradiated MWCNTs on electrical conductivity of a PET/graphite composite for a bipolar plate application

Kim D-H., Son Y., Kongju National University, KR

The effects of a compounding method and γ-ray treated multiwall carbon nanotubes (MWCNTs) on the electrical conductivity of graphite/PET composites were investigated. We found that dispersion of MWCNTs in the PET phase plays a critical [...]

Synthesis and characterization of copper oxide decorated zinc oxide nanorods

Lim S.K., Hong S.H., Hwang S.H., Kim H-S, Kim S., Lee D.J., Kim H-S, Kim S., DGIST(Daegu Gyeongbuk Institute of Science & Technology), KR

One-dimentional nanostructures in the form of nanorods, nanowires, nanofibers or nanotubes, appear as an exciting research area for their great potential of applications. Zinc oxide is an n-type semiconductor that has been well known for [...]

Fabrication and characterization of Eco-Friendly Heat Insulating Materials using inorganic Nanofillers such as Titanate Nanotubes and Layered Double Hydroxides

Hwang S.H., Daegu Gyeonbuk Institure of Science and Technology, KR

In this work, we have synthesized Titanate nanotube(TiNT) and Layered Double Hydroxide(LDH) nanoparticles and studied about their applicable properties as inorganic filler due to their high porous structure. The synthetic parameters affecting the particle size [...]

Radon Mitigation Efficiency using Nano-size Carbon Colloid

Kim D-H., Kim M-J, Kim S-H, Lee K.H., Kim D-H., Kim M-J, Kim S-H, Kim D-H., Kim M-J, Kim S-H, Jung K.S., Cho S.Y., Yonsei University, KR

Radon is classified as the second leading cause of lung cancer in the US. There have been plenty of trials to mitigate indoor radon gas which penetrated through the floor cracks, building materials and groundwater [...]

MD Simulations on the Momentum Transfer to Nano Contaminant Particle on Wafer Surface in Collisions with Cleaning Bullets

Choi M.S, Lee J.W., POSTECH, KR

This study aims to clarify the basic mechanism through MD simulations on momentum transfer during collisions between target contaminant and cleaning bullet particles both in the nanometer size range. Even in conditions where the contaminant [...]

Simultaneous removal of nano-sized contaminant particles with multi-modal size distribution using hybrid particle beams

Kim I., Lee J.W., POSTECH, KR

The removal of contaminant particles(CPs) as small as 10nm from wafer surface is essential in successful fabrication of nano-scale devices. The supersonic particle beam technique using nano-sized volatile bullet particles(BPs) was extremely effective in removing [...]
