Composite dielectric ceramics BaTiO3/SrTiO3 were prepared by spark-plasma-sintering method. The obtained ceramics showed flat temperature dependence of permittivity within the range of r.t. - 100oC. XRD and Raman measurements suggested that the present ceramics were consisted of BaTiO3 and (Ba,Sr)TiO3 solid solutions, and such microstructures were responsible for the above temperature dependence of permittivity.

In order to develop the high selective and high active adsorbent for the plasma perfusion therapy, we have examined the effects of ion substitution of hydroxyapatite lattice on the selective adsorption property of beta
2 microglobulin, which is the pathogenic substance related the chronic renal failure, toward bovine serum albumin. In this study, we prepared several zinc hydoxyapatites with different zinc contents and examined their beta
2 microglobulin selective adsorption property. We discussed the relation between structure and protein adsorption property of zinc hydoxyapatites.

Apatite fibers were synthesized by a homogeneous precipitation method. The scaffolds which enable 3D cell culture were fabricated by sintering the apatite fibers with carbon beads of
ca. 150 micron in diameter. In order to enhance the mechanical properties of the scaffolds, I-collagen gel solution was introduced into the pores in the scaffold. SEM observations of the resulting apatite/collagen scaffolds showed that the collagen-gel network was formed in the macro pores of the scaffolds. We conclude that hybridization of apatite-fiber scaffolds with I-collagen may be effective for the enhancement of mechanical properties of the scaffolds.

Hydroxyapatite (HAp) aggregates with c-axis orientation were prepared by a hydrolysis of CaHPO4∙2H2O (DCPD) in NaOH solution at 80-100 ºC. The HAp aggregates were composed of needle-like crystals which were aligned in c-axis direction perpendicular to the flat surface of the plate-like aggregates. The degree of c-axis orientation of the aggregates increased with increasing in heat treatment temperature. Differences of the growth rate of HAp crystals and supplying mechanism of Ca and PO4 from the DCPD caused morphological differences between oriented and random structures of the aggregates.

Apatite-fiber scaffolds which enable 3D-cell culture have successfully been developed on the basis of processing to control pore sizes of the scaffolds. In vitro/vivo evaluation of the resulting scaffolds were performed using rat-bone morrow cells as a model of osteoblast and animal models. The results clarified that the cells were three dimensionally attached, proliferated, differentiated to culture in a similar environment to human body. When the scaffolds including rh-BMP-2 or rat-bone marrow cell were implanted in subcutaneous tissue of rat/nude mouse, they showed good bone formation.

Bioactive ceramics have been attractive because they spontaneously bond to living bone. Organic-inorganic hybrids consisting of flexible polymers and the essential constituents of the bioactive ceramics are useful as novel bone substitutes, owing to mechanical properties analogous to those of natural bone. In the present study, organic-inorganic hybrids were synthesized from hydroxyethylmethacrylate (HEMA) by modification with titanium isopropoxide and calcium chloride. Their apatite-forming ability was examined in a simulated body fluid (Kokubo solution).

We used bovine serum albumin (BSA) as model protein and examined the effects of the contact with ceramics such as, alumina, silica, titania, zirconia on the aggregation of plasma in simulated body fluid. The secondary structure of BSA in contact with ceramic powders was examined by spectroscopic analysis. BSA solution in contact with ZrO
2 and TiO
2 was clouded. This indicates the BSA aggregation due to the conformational change of BSA. We can suppose that the difference of the interaction between protein and the bioceramic materials affects the conformation of protein.

We prepared the micro-thermoelectric hydrogen sensor with the combination of the thermoelectric effect of SiGe thin film and the Pt-catalyzed exothermic reaction of hydrogen oxidation. The first step of sensor manufacture process is to deposit thermoelectric SiGe thin film. The micro-heater and the electrodes were patterned by photolithography and lift-off technique. The third and last step is the back-side etching and the deposition of the Pt catalyst. The sensor operating at 100C detected hydrogen for the concentration from 0.01 to 3% in air, with a good linearity of voltage signal versus gas concentration.

In the near future, sensors for H2, CH4, C3H8 and CO gases will be more important, because fuel cell systems will be markedly increasing in our life. In our previous studies, we reported that the successful preparation of highly CO sensitive ZnO/SnO2 thin films by the sol-gel method. In this study, we report the H2 sensing properties of ZnO/SnO2 thin films. As a result, it was confirmed that the H2 sensitivity apparently depends on the microstructure of the ZnO/SnO2 thin films.

2 films were prepared using RF magnetron sputtering. The dependence of detection sensitivity to CO
2 on La content was evaluated by two-point probe method.
The crystallization of SnO
2 films was suppressed by La doping. Highest sensitivity was obtained with 5% La and at 200.degree.C.

We investigated ISFETs using new sensing material to monitor the primary components. We can successfully demonstrate single drop acid-rain analysis for real rainwater using pH and nitrate checkers using direct potentiometry. We also challenged high throughput analysis using Lab-on-a-Chip technology. We obtained preliminary results for nitrate analysis within 20 sec.

Sensor design of conductivity-type thin film gas sensors using semiconductor ceramics have been investigated for the detection of dilute NO
2 as well as dilute CH
3SH. For NO
2 sensors, WO
3 was used as a sensing material. The NO
2 sensitivity was much improved by controlling particle size, film thickness, and electrode structure. On the other hand, the high sensitivity CH
3SH sensor was developed by using BaSnO
3 particles which included fine grains in the shell.

Macroporous BaCO
3 films were prepared by a modified sol-gel technique employing polymethylmethacrylate (PMMA) microsphere film as template and Ba(CH
3COO)
2 aqueous solution as the barium source. The films (ca. 1-2 micron thick) exhibited ordered 3-D BaCO
3 frameworks with macropores derived from PMMA microspheres, after calcination of BaCO
3 precursor/PMMA composite films at 400C for 2 h. The ordered macropores were destroyed after calcination at higher temperatures, however, the high porosity was retained in the films. The NO
2 sensing properties of bulk acoustic wave resonator sensitized by macroporous BaCO
3 films are reported.
