Effects of ZnO buffer layer and depth profiling analysis of bulk heterojunction organic solar cells

Mbule P.S., Kim B.S., Kim T-H., Kim B.S., Kim T-H., Swart H.C., Ntwaeaborwa O.M., University of the Free State, ZA

Bulk heterojunction organic solar cells (BHJs) with ZnO nanoparticles buffer layer between the active layer and the aluminum (Al) top electrode were fabricated. The BHJs comprised of successive layers of poly(3,4ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), a blend of [...]

Biological synthesis of copper nanoparticles using plant extract

Lee G., Lee H.J., Lee G., Lee H.J., Jang N.R., Yun J.H., Song J.Y., Kim B.S., Chungbuk National University, KR

Copper nanoparticles were biologically synthesized using plant leaf extract as reducing agent. On treatment of aqueous solutions of CuSO4•5H2O with leaf extract (Magnolia), stable copper nanoparticles were formed. UV-vis spectroscopy was used to monitor the [...]

Hybrid Poly(L-Lactide) (PLA) Nanofibers Incorporating POSS-Modified Multiwalled Carbon Nanotubes Prepared by Electrospinning

Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Jeong I., Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Shinshu University, JP

Organic–inorganic hybrid composites have attracted considerable attention because of their distinctive physical and chemical properties. Specifically, the multiwalled carbon nanotube (MWNT)-polymer composites among them has expected when uniform dispersion of the MWNTs in the polymer [...]

Mechanical Properties of Metallized Single Nanofibers

Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Kimura N., Bang H-S., Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Watanabe Y., Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Enomoto Y., Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Shinshu University, JP

Our final goal is to make the metal nanofibers having good properties of metal and explore the mechanical properties of metalized single nanofibers. We are expecting that they would be strong like general metals. In [...]

Development of Melt Blown Electrospinning Apparatus of Isotactic Polyproylene

Watanabe K., Lee K.H., Lee Y.J., Nakamura T., Lee K.H., Lee Y.J., Kim B.S., Kim I.S., Kim K.W., Kim B.S., Kim I.S., Kim K.W., Kim B.S., Kim I.S., Kim K.W., Shinshu University, JP

Melt blown electrospinning is a method of combining melt blown with melt electrospinning. In this study, we developed the multi nozzle melt blown electrospinning machine. The significant point of this method is to use air [...]

Real-time detection of neurotransmitter using enzyme-immobilized CNT network transistors in 11 vessel occlusion rat model

Lee G.J., Lim J.E., Park H.J., Park H.K., Park J.H., Eo Y.H., Kim B.S., Park H.J., Park H.K., Park J.H., Choi S.K., Hong S., Park H.J., Park H.K., Park J.H., Kyung Hee University, KR

The field effect transistor (FET) made of carbon nanotube (CNT) can be used as sensor due to their extreme sensitivity to local chemical environments. Glutamate is the principal excitatory neurotransmitter in the brain, and its [...]

Numerical Analysis of Nano-imprinting Process Based on Continuum Hypothesis

Kim B.S., Kim H-C, Woo Y.S., Lee W.I., Oh S.I., Kim B.S., Kim H-C, School of Mechanical and Aerospace Engineering, Seoul National University., KR

Nano-imprint lithography (NIL) is a processing tech-nique capable of transferring nano-scale patterns onto a thin film of thermoplastics such as polymethyl methacrylate (PMMA). Feature sizes down to 10 nm have been demonstrated to be made [...]
