Linear-Logarithmic Two-Transistor Active Pixel Sensor with Wide Dynamic Range

Bae M., Choi B-S, Choi P., Jo S-H, Shin J-K, Kyungpook National University, KR
Image sensor technology has progressed from advanced semiconductor technology. The complementary metal–oxide–semiconductor (CMOS) process offers the capability of integrating smart functions on imagers in a single chip. As CMOS technology scales down, the pixel size [...]

Preparation and Characterization of Highly Dispersive Acrylic Acid/Styrene Submicrocapsules by using Miniemulsion Copolymerization

Ghim H-D, Hwang Y., Kim M.K., Kyungpook National University, KR
This study reports the preparation and characterization of acrylic acid/styrene (AA/St) submicrocapsule having high value of zeta potential by using phytoncide oil as a model material. AA/St submicrocapsules were prepared by miniemulsion copolymerization with 1,3-diphenyl-2-propanone, [...]

Tuning of Nafion® by HKUST-1 as coordination network to Enhance Proton Conductivity for Fuel Cell Applications

Choi S-J, Kim H.-J., Talukdar K., Kyungpook National University, KR
MOFs have highly ordered structures and modular nature that can serve as a scaffold to anchor acidic groups and improve efficient proton transfer pathways. HKUST-1, a MOF material containing CuII–paddle wheel type nodes and 1,3,5-benzenetricarboxylate [...]

Core-shell Silica-coated Iron Oxide Nanoparticles for Magnetic Hyperthermia

Bae H., Hong S., Iqbal Y., Rhee I., Kyungpook National University, KR
We report the synthesis and characterization of silica-coated iron oxide nanoparticles with a core-shell structure for magnetic hyperthermia. The nanoparticles of silica-coated iron oxide were synthesized using the reverse micelle method. The coating of the [...]

Quinaldine and Indole based pH Sensitive Colorimetric Chemosensor and their application of nanofiber

Bae J.S., Kim S-H, Son D.H. Lee Y-A., Kyungpook National University, KR
Colorimetric chemosensors are now considered as one of the most effective analytical method used in the environment monitoring. Colorimetric chemosensors for pH sensing can easily detect the primary danger or change of the surrounding environment [...]

Multi-Bit/Cell SONOS Flash Memory with Recessed Channel Structure

Han K-R, Kwon H-I, Lee J-H., Kyungpook National University, KR
A novel device structure for 4-bit/cell with recessed channel structure is presented and characterized for NOR-type nonvolatile memory (NVM) technology. In this paper, we studied a 4-bit/cell SONOS flash memory cell Since two transistors in [...]

Preparation and characterization of release behavior for hydrophilic drug loaded alginate nanohydrogels

Ghim H-D, Kim M.K., Kim Y.M., Lee H.Y., Lee S.M., Sohn S-O, Kyungpook National University, KR
Recently, there have been considerable interests in developing biodegradable nanoparticles as effective drug delivery devices. Alginate is one of the hydrophilic natural polymers having biodegradability and biocompatibility. It has possibility to apply in the controlled [...]

Fabrication of 3-Dimesional Cu Coaxial Cylinder using Porous Silicon MEMS Technology

Bae CH.H., Eun D.S, Kim Y.M., Lee J-H., Kyungpook National University, KR
Therefore, this paper reports 3-dimensional Cu coaxial cylinder with a thick OPS(oxidized porous silicon) in low resistivity silicon for application of microwave and RF integrated circuit technology. A novel on-chip 3D coaxial cylinder was fabricated [...]

RF-MEMS Voltage Tunable Capacitor using Electrostatic Forces

Kim Y., Lee J., Na D., Park S., Kyungpook National University, KR
In this paper, we have proposed a fabrication method of a RF-MEMS voltage tunable capacitor using Au-electroplating technique, which has one movable parallel plate with various structure of beams. We applied an electrostatic method and [...]
