Mechanical Characterization of Prion Fibrils using Coarse-grained Modeling Approach in Silico

Yoon G., Kim Y.K., Eom K., Na S., Korea university, KR

Recently, prion is aroused interest with amyloid for its fatality in human and animal`s disease such as Creutzfeldt–Jakob disease and bovine spongiform encephalopathy. The prion has nanoscale long fibrillar form and exists high mechanical properties, [...]

Multifunctional Micropatterned Nanofiber Capable of Cell Patterning, Metabolite Detection, and Growth Factor Delivery

Koh W.G., Lee H.J., Lee H.W., Lee H.J., Lee H.W., Park S., Yonsei University, KR

This study describes the development of multifunctional nanofiber scaffolds consisting of multiple layers of nanofiber scaffolds and nanofiber-incorporated PEG hydrogels. We fabricated double-layered nanofiber scaffolds that were micropatterned with PEG hydrogels by combining two-step sequential [...]

Simultaneous Measurement of Nitric Oxide and Oxygen Dynamics during Myocardial Ischemia Reperfusion of Rat

Lee G.J., Kang S-W, Kim O.K., Kim S.K., Kim O.K., Kim S.K., Shin J.-H., Park H.K., Kyung Hee University, KR

Myocardial function is dependent on a constant supply of oxygen from coronary circulation. Therefore the accurate measurement of oxygen concentration in postischemic myocardium is crucial to the assessment of myocardial viability and function. Nitric oxide [...]

Electric Double Layer Simulation on Transient State for Sensitivity Enhancement of Affinity-Based Biosensor

Woo J-M, Kim S-H, Park Y.J., Seoul National University, KR

We have presented a numerical simulation for the affinity-based electrical biosensor system on the steady and transient state. Considering the screening length in the solutions, the solution with low ion concentration can be better measurement [...]

Robust thin spin-coated silver films with polymer thin layers for SPR image sensor applications

Son J.-H., Cho Y-J, Lee M.H., Sungkyunkwan University, KR

We fabricated thin silver films with thicknesses of 20 nm, 40 nm, and 60 nm on a prism using a spin coating method for SPR image sensor module applications. An aqueous silver ionic complex solution [...]

A study of the Demolding Force in Nano Imprint Lithography For Different Surface Treatments

Moon S.N., Jung J-M, Lee K.M., Lee W.I., Lee K.M., Lee W.I., Seoul National University, KR

The NIL process can be divided into two steps: the pressing and demolding stages. In the pressing stage, micro/nano scale patterns on a mold are transferred to a polymer resist. During this stage, there are [...]

A new method for vertical growth of silicon nanowire in the vapor-liquid-solid (VLS) process

Kim Y.J., Suh D., Lee M.L., Ryu H., Electronics and Telecommunications Research Institute (ETRI), KR

We present a new facile method for vertical growth of the silicon nanowire (Si NW) that obviates the need for SiCl4 in vapor-liquid-solid (VLS) process. The VLS process that involves SiCl4 has two major disadvantages; [...]

Investigation of Metal Nano Layer Formation by the Tunneling Current through the Thin Oxide Film in the Electrolyte–Oxide–Silicon System

Lee S-H., Cheon J-H, Choi S., Choi Y., Choi S., Choi Y., Park Y.J., Seoul National University, KR

In the researches on Electrolyte–Oxide–Silicon (EOS) system, tunneling current through the gate insulator has been considered as an undesirable factor causing reliability issues such as gate insulator degradation and interface state generation. In this work, [...]

Numerical Study on a passive micromixer with sinusoidal channel walls

Afzal A., Kim K-Y, Inha University, KR

Mixing of liquid samples in microfluidic systems has attracted many researchers mainly due to small characteristic dimensions of these channels, absence of turbulence and small diffusion coefficients. Depending on the mode of operation, different realizations [...]

Critical heat flux (CHF) enhancement of the nanofluids by the electrical explosion of a wire in liquids

Park E., Park H., Bang I., Park E., Park H., Ulsan National Institute of Science and Technology(UNIST), KR

Nanofluids, dispersed nanoparticles in base fluid, have been drawing the attention as heat transfer fluid for enhancement of critical heat flux (CHF). The enhancement of CHF contributes to increase the safety margin of thermal system. [...]
