A new strategy of using unstable offshore wind power by combination with pumped storage generation with reversible pump turbine

Zhai Y., Ma J., Mitobe M., Uehara S., Gon S., Sugawara A., Niigata University, JP

The cost of wind energy resources are low and it is abundant, with a characteristic of the energy saving and eco effect. But if large-scale wind power be merged into the power network directly, the [...]

ROS Evaluation for Series of CNTs Using the ESR Method and the Effects of CNT Mophology

Tsuruoka S., Takeuchi K., Koyama K., Endo M., Fujisawa K., Matsumoto H., Saito N., Usui Y., Porter D.W., Castranova V., Shinshu University, JP

Carbon nanotubes (CNTs) are becoming important materials in industry. It is a concern that CNTs may induce carcinogenic responses through pulmonary exposure. It has been recently reported1-6 that CNTs scavenge ROS depending on their morphology. [...]

Simulation of Back-Electrode Effects on Lags and Current Collapse in Field-Plate AlGaN/GaN HEMTs

Horio K., Onodera H., Fukai T., Shibaura Institute of Technology, JP

Two-dimensional transient analysis of gate-field-plate AlGaN/GaN high electron mobility transistors with a backside electrode is performed by considering a deep donor and a deep acceptor in a buffer layer. Effects of introducing a field plate [...]

Studies on Photothermal Effect in Nanofluidic Channel Toward Ultrasensitive Detection of Nonfluorescent Molecules Using Differential Interference Contrast Thermal Lens Microscope

Shimizu H., Mawatari K., Kitamori T., The University of Tokyo, JP

Absorption spectroscopy in nanofluidic channel was investigated for ultrasensitive detection of nonfluorescent molecules in nanospace. Recently, chemical analysis systems have been rapidly miniaturized from microspace to nanospace, which requires ultrasensitive detection of a broad range [...]

Evanescent wave-based particle tracking technique for velocity distribution in extended nanochannel

Kazoe Y., Iseki K., Mawatari K., Kitamori T., The University of Tokyo, JP

We developed a flow measurement technique of velocity distribution in extended nanochannel (10- 1000 nm), using fluorescent tracer nanoparticles and the evanescent wave which penetrates into a liquid medium with an exponential decay from the [...]

Highly Crystalline Poly(lactic acid) (PLA) Alloys Containing Stereocomplexes

Oyama H.T., Abe S., Rikkyo University, JP

Poly(lactic acid) (PLA) is known as a bio-based polymer, which usually has low heat tolerance. Furthermore, the brittleness of PLA limits its applications. It is reported that the melting temperature (Tm) of crystalline stereocomplexes (sc) [...]

Effects of Preparation Methods and Electronic States of the AuPd Bimetallic Nanoparticles on the Activity for Aerobic Oxidation of Alcohols

Nishimura S., Yakita Y., Katayama M., Higashimine K., Ebitani K., Japan Advanced Institute of Science and Technology, JP

Bimetallic nanoparticles (NPs) have attracted great interests and potentials in advanced nancatalysts because they achieved unique catalytic performances different from those of monometallic NPs. However, the contributions of their morphologies and/or electronic states to the [...]

Extraordinary Activity of Nanodispersed Bimetallic NiFe Phosphide Catalysts for the Conversion of a Biomass Model Compound

Oyama S.T., Cho A., Shin J., Takagaki A., Kikuchi R., The University of Tokyo, JP

The present work deals with the development of new catalysts, transition metal phosphides, which have outstanding activity for hydrodeoxygenation of pyrolysis oil. The study is significant as it leads to the production of high-energy content [...]

Effect of furnace temperature on the nucleation behavior and configurations of carbon nanoparticles

Ono K., Watanabe A., Matsukawa Y., Saito Y., Aoki H., Aoki T., Fukuda O., Aoki H., Aoki T., Yamaguchi T., Tohoku University, JP

The objective of the present study is to examine the impact of nucleation behavior and particle size distribution on morphology of carbon black. We used a fixed sectional approach applying the detailed chemical kinetic reaction [...]
