Low-cost spin-coatable, Transferable, and High-k Ion Gel Dielectric for Flexible Eletrowetting

Narasimhan V., Sanjairaj V., Park S.Y., National University of Singapore, SG

Electrowetting-on-dielectric (EWOD) is an emerging liquid-handling technology, enabling the wettability modulation of a liquid on a solid surface with an applied electric field. Recently, EWOD has been attractively used on flexible substrates to show potential [...]

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 [...]

Electrowetting-driven Solar Trackers for concentrated photovoltaic (CPV) rooftop applications

Park S.Y., Kuo J., Gould K., Teledyne Scientific & Imaging, US

Concentrated photovoltaic (CPV) technologies, which use additional optics (lenses or mirrors) to concentrate a large amount of sunlight onto a small area of the cells, can reduce the cost of PV systems. One of the [...]

The effect of nanoparticles on the translucency and antimicrobial activities of experimental resin cements

Lim B.S., Ahn S.J., Park S.Y., Seoul National University, School of Dentistry, KR

The purpose of this study was to evaluate the effect of the nanoparticles in experimental resin cements on opacity (contrast ratio) and antibacterial activities. Experimental resin cements were prepared with three different kinds of fillers: [...]

Atomistic Simulation on Boron Transient Diffusion during in Pre-amorphized Silicon Substrate

Park S.Y., Cho B-G, Won T., Inha University, KR

We investigated the boron diffusion in the silicon posterior to PAI (pre-amorphization implant) in order to understand the mechanism for amorphization process and generation-recombnation of defects. Silicon atoms were weighed as a new pre-amorphization implant [...]

Numerical Stress Analysis on Thermal Nano-Imprint Lithography

Cho B-G, Park S.Y., Won T., Inha University, KR

This paper investigations the stress distribution of the polymer through numerical simulations during thermal NIL. Numerical results explained characteristic phenomena which never appear in continuous line-and-space patterning cases. We believe that numerical simulations with more [...]

Ab-initio Calculations of Uniaxially and Biaxially Tensile Stress Effect

Kim Y.K., Park S.Y., Won T., Inha University, KR

In this paper, we present an ab-initio study on energy configurations, minimum energy path (MEP), and migra-tion energy for neutral indium diffusion in a uniaxial and biaxial tensile strained {100} silicon layer for the first [...]

Simultaneous Determination of Heavy Metals Using Array Based Optical Chemical Sensor

Choi Y., Ryoo D., Park S.H., Park S.Y., Park S.H., Park S.Y., Jeonju University, KR

A sol-gel optical chemical sensor encapsulated with complexing agents for simultaneous detection of selected heavy metals such as chromium, lead, mercury, and iron in aqueous media was fabricated. The sensor was prepared by acid catalyzed [...]
