Characterization on Dioxin Emission of TiO2 Nanoparticle-Encapsulating Poly(vinyl chloride) (TEPVC) compared to conventional PVC

Yoo H., Kim S-H, Lee A.R., Kwak S-Y, Seoul National University, KR

In our previous study, we first prepared TiO2 nanoparticle-encapsulating poly(vinyl chloride) (TEPVC) aiming at breakthrough to enhance the dispersibility of TiO2 nanoparticles in PVC matrix to maximize catalytic activities of TiO2 nanoparticles. The present study [...]

Determination of micro-structural properties with x-ray absorption fine structure

Han S.-W., Park S.H., Yu H.-J., Jeong E.-S., Kim S-H, Kim Y.J., Kim S-H, Kim Y.J., Yi G.-C., Chonbuk National University, KR

We studied the structural properties of ZnO nanostructures with x-ray absorption fine structure (XAFS) to understand the growth mechanism of vertically aligned ZnO nanorods of the average diameter of 50 - 150 nm. The orientation-dependent [...]

Compact Electromagnetic XY Stage with Nano Scale Resolution and Vibration Resistance

Lee K-I., Kim S-H, Cho J-W, Choi Y.J., Shin J-K, Yoo J.C., Choi Y.J., Korea Electronics Technology Institute, KR

The design, fabrication, and the measurement results of an electromagnetic XY stage are presented. The device has an anti vibration structure and shows a high fill factor of 45% due to its unique structure. Furthermore, [...]

Sirna Nanomedicines for Cancer Gene Therapy

Kim S-H, Park T.G., Korea Advanced Institute of Science and Technology, KR

We developed a polyelectrolyte complex (PEC) micelle-based delivery system for treatment of prostate cancer. A PEGylated siRNA targeting human vascular endothelial growth factor (hVEGF) was synthesized. The hVEGF expression was almost completely inhibited in vitro [...]

Park S.H., Seo S.-Y., Kwak C.-H., Lee Y.B., Kim S-H, Han S.-W., Chonbuk National University, KR

Vertically well aligned ZnO nanorod arrays with a diameter of 50 - 150 nm were fabricated on Al2O3 substrates with and without GaN interlayers, and consequently covered with a crystalline ZnO film in-situ by a [...]

Fabrication of electrochemical bio-sensors for the detection of glucose and hydrazine using ZnO nanonails grown by the thermal evaporation process

Umar A., Kim J.H., Kim S-H, Kim J.H., Kim S-H, Park Y.K., Hahn Y.B., Chonbuk National University, KR

Well-crystallized zinc oxide nanonails have been synthesized in a large quantity via a thermal evaporation method using the metallic zinc powder without the use of any metal catalyst or additives. The detailed structural and optical [...]

Recent Upgrades and Applications of UFDG

Fossum J.G., Trivedi V.P., Chowdhury M.M., Kim S-H, Zhang W., University of Florida, US

Recent upgrades of UFDG, a process/physics-based compact model for nonclassical MOSFETs having ultra-thin Si bodies (UTB), are overviewed, and several recent applications of the model are presented, exemplifying the potential benefits of FinFETs in nanoscale [...]

Nano Gripper using Carbon Nanotube

Lee J.S., Kwon S-K, Choi J-S, Kang G-S, Kwak Y-K, Kim S-H, KAIST, KR

In this paper, we proposed a nano gripper that was made from two nano probes. And, those nano probes were made from the tungsten tip and multi-wall carbon nanotube with acrylic adhesive under optical microscope. [...]
