Application of Vertical Micororeactor Stack with Polystylene Microbeads to Immuno Assay
This paper proposes a vertical microreactor stack, a new concept of the microreactor, using vertical fluid flow operation and multifunctional fluid filters and vertically stacked reservoirs. The vertical fluid flow operation utilizes the surface tension of the liquid/ gas interface and pneumatic pressure to control the liquid behavior in vertical microreactor stack. The functions as microvalve, microcahnnel and micromixer of the fluid filter are estimated by computational fluid dynamics (CFD) simulation and experiments. The enzyme linked immuno-solvent assay is demonstrated by using vertical microreactor stack and the calibration curve was successfully taken.
Large area and wide dimension range x-ray lithography for lithographite, galvanoformung, and abformung process using energy variable synchrotron radiation
We developed an x-ray lithography system for the “lithographite, galvanoformung, and abformung” process using synchrotron radiation at the NewSUBARU facility of the University of Hyogo, Hyogo, Japan. The x-ray lithography system can utilize two different energy regions: one is a high-energy region: from 2 to 12 keV, and the other is a low-energy region from 1 to 2 keV. Each energy region can be selected in accordance with the size and shape of the desired microstructures. Large-area patterning across an A4-size area was successfully performed with a highly uniform pattern thickness. Furthermore, high-aspect-ratio patterning using a high-x-ray-energy region was also achieved using this x-ray lithography system.
DEM generation from new VIR sensors: IKONOS, ASTER and Landsat-7
DEM generation is a living R&D topic since new-launched satellite images can be used to generate stereoscopic images. Using a coplanarity equation model developed at CCRS and an automatic matching method developed at PCI, DEMs are generated with new VIR stereo data. Accuracy of 4.9 m with high-resolution IKONOS images, and 33 m and 101 m with medium-resolution ASTER and Landsat-7 ETM/sup +/ images respectively are obtained. The same matching accuracy of one-pixel is translated into worse results with Landsat due to a small B/H ratio of 0.15.
