Improve of Photovoltaic Performance of Dye-sensitized Solar Cell by Concentrating Solar Energy

Kim Y-W., Cho E., Choi S.C., Choi S.C., Lee D.W., Pusan National University, KR

Dye-sensitized solar cell (DSSC) is extremely promising because it is made of low-cost materials and does not need elaborate apparatus to manufacture against the silicon solar cell. Accordingly, the DSSC is constantly researched globally. One [...]

A Permselective Layered Silicate Modified by Acid-treatment and Its Use for Blocking of Methanol Crossover in DMFC

Yoo H., Kim J.H., Kwak S-Y, Seoul National University, KR

Layered silicates currently find uses in ion-exchange, adsorption, catalysis and fabrication of nanocomposites. Several layered silicates have channel systems or open frameworks within layers. They can be used to solve the problem for direct methanol [...]

Charge/Discharge Property and Cycle Life of Li4Ti5O12/LiCoO2-LiNi1-x-yCoxAlyO2 Cell for Electricity Storage Applications: Effect of Cell Design Parameters

Song M.-S., Samsung Advanced Institute of Technology, KR

In this work, Li4Ti5O12 has been used as an anode material in lithium-ion batteries for electricity storage applications, which operate under intermittent cycling conditions with higher charge/discharge rates than 4C (i.e., current extracting the full [...]

Enhanced Photoluminescence Properties of Li/Al-doped YPO4:Eu phosphors

Yi S.S., Silla University, KR

we have prepared different concentrations of Li/Al-doped YPO4:Eu0.05 phosphors by solid state reaction method and the synthesized materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), excitation and emission measurements. The dependence of [...]

Transparent polymer photodetector to control electronic devices

Jeon K.M., Korea Advanced Institute of Science and Technology, KR

Polymer semiconductor materials are being used in variable applications such as OLED, OPV and Organic sensor, because polymer semiconductor materials have advantages like solution processing, low-cost, flexible, and easy large area fabrication. However, performance of [...]

Diesel Production from Waste Disposal using Catalytic Dissociation on Mn-zeolite Catalyst

Kim M.C., Lee K.B., Cheongju University, KR

The approach for catalytic dissociation of waste diaposal using various catalysts is presented. This approach includes two principal steps: a characterization of catalysts is used to determine the active site of prepared catalysts, and the [...]

Novel Mycotoxin Collection System using Magnetic Nanoparticles for Determination of Aflatoxin B1 and Zearalenone in Feed

Cha S-H, Lee J-K, Jung H-S, Kim H.-J., Kim S-H, Kim H.-J., Kim S-H, Choi C-U, Kang H-G, National Veternary Research and Quarantine Service, KR

Introduction: A common method for determination of mycotoxins contaminated in feeds combines immunoaffinity chromatography (IAC) and high-performance liquid chromatography (HPLC) with UV detection1,2. However, the IAC method to collect mycotoxins is expensive and time-consuming. Moreover, [...]

Nanoscale structure and property changes in collagen fibrils on the extracorporeal shockwave therapy applications of the rat Achilles tendon injury

Choi S., Lee G.J., Chon J., Chae S.-J., Yoo S.-D., Park H.K., Park J.H., Kim K.S., Park H.K., Park J.H., Kyung Hee University, KR

Extracorporeal shockwave therapy (ESWT) is popular in the treatment of musculo-skeletal injuries. However, the mechanism by which such therapy might have an effect on tendon injury is unknown. The Achilles tendons are mainly composed of [...]
