  • Graphene−Metal Particle Nanocomposites
    Journal of Physical Chemistry C, 2008
    Co-Authors: Chao Xu, Xin Wang
    Abstract:

    Graphene sheets, which possess unique nanostructure and a variety of fascinating properties, can be considered as promising nanoscale building blocks of new composites, for example, a support material for the dispersion of nanoParticles. Here, we present a general approach for the preparation of graphene−Metal Particle nanocomposites in a water−ethylene glycol system using graphene oxide as a precursor and Metal nanoParticles (Au, Pt and Pd) as building blocks. These Metal nanoParticles are adsorbed on graphene oxide sheets and play a pivotal role in catalytic reduction of graphene oxide with ethylene glycol, leading to the formation of graphene−Metal Particle nanocomposites. The typical methanol oxidation of graphene−Pt composites in cyclic voltammograms analyses indicated its potential application in direct methanol fuel cells, bringing graphene−Particle nanocomposites close to real technological applications.

  • Iron Loss Reduction in the Cores of Induction Heating Coils for Small-Foreign-Metal Particle Detector With a 400-kHz SiC-MOSFETs High-Frequency Inverter
    2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia), 2018
    Co-Authors: Takuya Shijo, Yujiro Noda, Hiroaki Yamada, Yuki Uchino, Toshihiko Tanaka
    Abstract:

    This paper presents iron loss reduction in the cores of induction heating (IH) coils for a small-foreign-Metal Particle (SFMP) detector with a 400-kHz SiC-MOSFETs high-frequency inverter. A new IH coil shape, which can reduce iron loss, is proposed for the stable and continuous operation of the SFMP detector. Magnetic field analysis results using JSOL JMAG software, which is a 3D full-wave electromagnetic field simulation software, demonstrate that the iron loss caused by the newly proposed IH coils is decreased by 71.8 % compared to the previously proposed IH coils. The stable and continuous operation of the SFMP detector with the newly proposed IH coils can be achieved. It is also shown that SFMP represented by 0.3-mm-diameter stainless steel balls (SUS304) on the films can be detected with the newly proposed IH coils using JSOL JMAG software. A prototype experimental setup of the SFMP detector with the newly proposed IH coils is constructed and tested. Experimental results demonstrate that a 400-kHz SiC-MOSFETs high-frequency-inverter-based SFMP detector with the newly proposed IH coil can heat SFMPs, which can be observed by a thermographic camera. Therefore, the authors concluded that the 400-kHz SiC-MOSFETs high-frequency-inverter-based SFMPs detector with the newly proposed IH coil is applicable for high-performance chemical film production lines.

  • A 400 kHz SiC-MOSFETs high-frequency inverter for small-foreign-Metal Particle detection
    2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC), 2016
    Co-Authors: Takuya Shijo, Shinya Kurachi, Yujiro Noda, Hiroaki Yamada, Toshihiko Tanaka
    Abstract:

    This paper presents the detection of small-foreign-Metal Particles using a 400 kHz SiC-MOSFETs high-frequency inverter. A 400 kHz SiC-MOSFETs high-frequency inverter is constructed and tested, and then applied to the small-foreign-Metal Particles detection on high-performance chemical films (HPCFs) with induction heating (IH). Experimental results demonstrate that the developed 400 kHz SiC-MOSFETs high-frequency inverter can heat small-foreign-Metal Particle on HPCFs with IH. Thus, small-foreign-Metal Particle can be detected with the help of a thermographic camera along with the constructed 400 kHz SiC-MOSFETs high-frequency inverter. Losses caused by SiC-MOSFETs are analyzed in detail to improve power conversion efficiency of the constructed high-frequency inverter. Experimental results also demonstrate that parallel connections of two SiC-MOSFETs effectively reduces the losses, where power conversion efficiency is 96.8 % and improved by 1.9 %.
