Color-Masked and Nano-Size Catalysts Embedded in Polymers for Reducing Dioxin Emission

Choi J., Yang K.S., Jeong Y.S., Chung J.S., Pohang University of Science and Technology, KR

People have begun to make polymer containing catalysts for dioxin decomposition. To make high functional polymer containing catalysts for dioxin decomposition, catalysts have very small size and are colorless for their various application. The objectives [...]

Synthesis and Characterization of Nanostructured Undoped/Doped CuO Films and their Application in Photoelectrochemical Water Splitting

Chaudhary Y.S., Shrivastav R., Satsangi V.R., Dass S., Dayalbagh Educational Institute, IN

Metal oxide semiconductors are the most promising materials for photoelectrochemical production of hydrogen on account of a) easy availability, b) low cost, c) simple preparation methods and d) stability. The nanostructured metal oxides are in [...]

Synthesis and Characterization of a Series of Star-Branched Poly(epsilon-caprolactone)s with Nanoscale Molecular Architectural Variation

Choi J., Song H.J., Kwak S-Y, Seoul National University, KR

In this study, a series of star-branched poly(epsilon-caprolactone)s (SPCLs) was synthesized with nanoscale molecular architectural variation in arm numbers and lengths by ring-opening polymerization under bulk condition. Arm numbers were varied to be 3, 4, [...]

Viscoelastic Relaxation and Molecular Mobility of Hyperbranched Poly(epsilon-caprolactone)s in Their Melt State

Song H.J., Choi J., Kwak S-Y, Seoul National University, KR

The dynamic viscoelastic relaxation behavior and the molecular mobility of hyperbranched poly(epsilon-caprolactone)s (HPCLs) possessing the molecular architectural variation and their linear counterpart, linear poly(epsilon-caprolactone) (LPCL), were characterized and evaluated in conjunction with their specific molecular [...]

Nano Architecture MEA for Next Generation Fuel Cell

Schneider J., Picard G., Seye M-F, Nanometrix Inc., CA

The Schneider-Picard (SP) method for industrial monolayer and ultra-thin film deposition has shown a great effectiveness for the production with nano scale architecture for fuel cell Membrane Electrode Assembly (MEA). Today, MEA's are built in [...]

Supported Mixed Metal Nanoparticles and PFA-Nafion Nanocomposite Membrane for Low Temperature Fuel Cells

Chan K-Y, Ren J.W., Liu J., Wang H.T., Ding J., Tsang K.Y., Lee T.J., The University of Hong Kong, HK

Performance of low temperature fuel cells depends critically on the nanostructures of the material components in the electrodes and membranes. Some studies are reported here for 1) mixed metal nanoparticles supported on mesoporous carbon and [...]

Effects of the Addition of TiO2 Nanoparticles for Polymer Electrolytes Based on Porous Poly(vinylidene fluoride-co-hexafluoropropylene)/Poly(ethylene oxide-co-ethylene carbonate) Membranes

Jeon J-D, Kim M-J, Chung J.W., Kwak S-Y, Seoul National University, KR

In order to ameliorate the performance of polymer electrolytes, we report on a novel solvent-free polymer electrolyte filled with viscous poly(ethylene oxide-co-ethylene carbonate) (P(EO-EC)) into a porous membrane. In addition, to enhance the conductivity and [...]
