INTERFACE SPIN-WAVE OF COUPLED SEMI-INFINITE MAGNETIC SUPERLATTICE

The interface spin-wave (ISW) modes or coupled semi-in-finitemagnetic superlattices separated by a nonmagnetic layer have been studied, by use of the magnetostatic method. A general expression of the ISW dispersion relation is obtained. Detailed calculations are performed in the special case where the ttwo semi-infinite superlattices is considered to be identical and the external magnetic field, is parallel or perpendicular to the surface of the. layers. Some results about ISW modes are discussed.     

Present status and future prospect of design of Pt–cerium oxide electrodes for fuel cell applications

In the research field of proton exchange membrane fuel cells, the design of electrocatalytic activities on Pt-oxide promoter in the anode side has attracted attention for improvement of CO tolerance of Pt in anode side and a lowering of large over-potential loss of the oxygen reduction reaction on the cathode in the fuel cells. In the Pt-oxide promoter series, Pt–CeOx/C is one of the unique systems. It is because the unique behavior of CeOx such as electrochemical redox reaction between Ce3t and Ce4t in the anodic and cathodic reactions of fuel cell is observed. The present short review gives an overview of the recent works for improvement of the CO tolerance of Pt in the Pt–CeOx/C anodes and enhancement of the oxygen reduction reaction activity on Pt in the Pt–CeOx/C cathodes for fuel cell application. To show the design paradigm for fabrication of high quality Pt–CeOx/C electrodes, the authors re-introduced parts of our research results to highlight the important role of interface structure of Pt–CeOx based on the ultimate analysis results. The usefulness of the combined approach of microanalysis and the processing route design is presented.

Web-Based Interactive Simulation of Weft Knitted Fabric

In order to realize parametric simulation of three- dimensional (3D) fabric structure based on web,a 3D model describing a plain knitted fabric,in which the cross- section of the yarn is circular shape and the path of the yarn is cubic B-spline curve,is proposed in this paper. With this model,the 3D simulation of the loop and of the basic structures of the knitted fabrc is realized by using Virtual Reality Modeling Language (VRML). The virtual simulation scene is suitable for network transmission with freely available VRML browsers and can be translated,scaled and rotated quite arbitrarily. By using Java and External Authoring Interface (EAI) technology,the web- based interactive simulation platform of weft knitted fabric is established. The user can input type of structures,basic fabric parameters,and yarn colors interactively to obtain a more realistic simulation result in real-time. A new approach is provided to imitate the knitted fabric 3D appearance on network.
