Im K., Ahn C-G, Yang J.H., Baek I-B, Choi C-J, Lee S., Hwang H., Cho W-J, Choi C-J, Electronics and Telecommunications Research Institute, KR

UTB ISG MOSFET with gate length of 60 nm was fabricated with HfO2 gate dielectric and Pt gate electrode. The proposed device has some advantage over conventional replacement gate process. Besides simpler process, the remaining [...]

Amphiphilic Self-assembled Nanoparticles Composed of Chitosan and Ursolic Acid for Protein Delivery on the Skin

Lee S.B., Cho K., Shim J.K., Korea Institute of Industrial Technology, KR

Several promising studies have been reported for the protein delivery such as cytokines using nano-sized particles, which have detrimental effect on the loading the protein without localization and releasing it without deactivation. To design the [...]

Analysis of the Droplet Ejection for Piezoelectric-driven Industrial Inkjet Head

Sim S., Park C., Park S-J, Park C., Park S-J, Yoo Y., Kim Y., Joung J., Oh Y., Samsung Electro Mechanics Co., KR

A hybrid design tool combining one-dimensional(1D) lumped parameter model and three-dimensional(3D) computational fluid dynamics (CFD) approach has been developed and applied to industrial inkjet head design for the application of direct writing on printed circuit [...]

Magnetohydrodynamic (MHD) Complex Flow Generation in Microchannel

Kim D.S., Kwon T.H., Pohang University of Science and Technology (POSTECH), KR

In this paper, we present design methodologies for magnetohydrodynamic (MHD) complex flow generation in a simple straight microchannel in which electrodes are patterned on two side walls and bottom wall. The required applied voltage conditions [...]

Chitosan Nanoparticles for the Effective Vaccine Delivery System

Kim B.G., Kang I.J., Kyungwon University, KR

There are four genes of S, C, X, P in HV DNA. S gene has the pre-S region composed of pre-S1 and pre-S2 as an encoding gene of surface antigen. C gene is in the [...]

Fast and Easy Detection System of Protein Glycosylation by Using Resonant Energy Transfer between Nanoparticles

Oh E., Lee D., Kim H-S, Korea Advanced Institute of Science and Technology, KR

We construct the new glycosylation detection system using Resonance Energy Transfer (RET) between gold nanoparticles (AuNPs) and semiconductor quantum dots (QDs). RET can be induced by biomolecular interactions between concanavalin A (conA)-conjugated AuNP (conA-AuNP) as [...]
