Instantaneous Carbon—Carbon Bond Formation Using a Microchannel Reactor with a Catalytic Membrane.
ABSTRACT Instantaneous catalytic carbon-carbon bond forming reactions were achieved in a microchannel reactor having a polymeric palladium complex membrane. The catalytic membrane was constructed inside the microchannel via self-assembling complexation at the interface between the organic and aqueous phases flowing laminarly, where non-cross-linked polymer-bound phosphine and ammonium tetrachloropalladate dissolved, respectively. A palladium-catalyzed coupling reaction of aryl halides and arylboronic acids was performed using the microchannel reactor to give quantitative yields of biaryls within 4 s of retention time in the defined channel region.
Conference Paper: Electrical machine fault detection using adaptive neuro-fuzzy inference[Show abstract] [Hide abstract]
ABSTRACT: This paper proposes a new integrated diagnostic system for induction machine electrical fault diagnosis by means of a neurofuzzy approach. New features that are of multiple frequency resolutions are extracted by wavelet packet decomposition of the stator current. These features can then clearly differentiate the healthy and faulty conditions. Features with different frequency resolutions together with the slip speed of the induction motor am used as the input sets for a neuro -fuzzy inference system. Two common electrical faults, the rotor bar breakage and the air gap eccentricity are considered. The system is validated on a 5 HP three-phase induction motor. Successful implementation of the proposed diagnostic system has been demonstratedIFSA World Congress and 20th NAFIPS International Conference, 2001. Joint 9th; 08/2001

Conference Paper: Micro and Nano Chemical System on Chip[Show abstract] [Hide abstract]
ABSTRACT: Integrated micro chemical systems have been expected as evolutional tools for high speed, functional and compact instrumentations for analysis, synthesis, bio and related sciences and technologies. We have developed general methods for micro integration of chemical systems on the basis of the concept being similar to electronics. In place of resistor, capacitor, and diode in IC, micro unit operations for mixing, extraction, phase separation, etc. have developed as integrated components of microchemical systems. There are two directions of our microchip chemical technologies. One is to make these technologies practical and to commercial use of micro-meter scale chemical system on chip. And the other one is to extend the method to nano-meter scale chemical experiment which is opening new horizon of chemical research tool.Solid-State Sensors, Actuators and Microsystems Conference, 2007.
