- Creating mesocrystalline ferroelectric nanocomposites and verification of their enormous piezoelectric and dielectric responsesJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 2014/04 -2017/03Author : FENG Qi; KUSUNOSE TakafumiIn the present study, mesocrystalline ferroelectric nanocomposites constructed from tow-kinds of nanocrystals with same crystal-axis orientation were synthesized by using our original soft chemical process, and their ferroelectric, dielectric, and piezoelectric behaviors were studied. We have succeeded in the syntheses of some ferroelectric mesocrystalline nanocomposites, such as BaTiO3/SiTiO3, BaTiO3/CaTiO3, BaTiO3/(Bi0.5Na0.5)TiO3, and SrTiO3/(Bi0.5Na0.5)TiO3 for the first time. The nanostructural, ferroelectric, dielectric, and piezoelectric studies revealed that 7 times and 5 times of enhanced piezoelectric and dielectric responses, respectively, were achieved by introduction of the lattice strain at the heteroepitaxial interface between two-kinds of the nanocrystals in the mesocrystalline nanocomposites. These results reveal that the enormous piezoelectric and dielectric responses can be induced by the lattice strain at the heteroepitaxial interface using the strain engineering.Creating mesocrystalline ferroelectric nanocomposites and verification of their enormous piezoelectric and dielectric responsesJapan Society for the Promotion of Science：Grants-in-Aid for Scientific R...See More
- Explication of a mechanism for the inhibitory effects of apatite on a metallic corrosion and the development of preservation concreteJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 2014/04 -2017/03Author : Kakegawa HisaoHydroxyapatite (HAP) significantly inhibited the corrosion of iron plates in sodium chloride solution and the releases of iron ions from iron plate. No formation of the layer of newly formed chemical composition on the plate surfaces was observed by analysis with TEM. The corrosion electric potentials of metals were increased. The linear sweep voltammetry (LSV) between iron and platinum electrode were significantly inhibited by HAP. It was suggest that the inhibitory effect of HAP on the anode reaction of iron corrosion reaction seems to be caused by some physical mechanisms. The fresh-concrete containing HAP fitted with JIS standard. The compressive strength of the test pieces with HAP were more than 40 N/mm2 as well as those of the test pieces without HAP. The inhibitory effects of HAP on the corrosion of iron sands in the concrete test pieces containing iron sands with HAP were confirmed in the sodium chloride solution with 1N hydrochloric acid.Explication of a mechanism for the inhibitory effects of apatite on a metallic corrosion and the development of preservation concreteJapan Society for the Promotion of Science：Grants-in-Aid for Scient...See More
- Hydrothermal treatment for improvements in the strength and functions of anodic oxidation films formed on the biomaterial titanium alloy.Japan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 2010 -2012Author : TANAKA Yasuhiro; FENG Qi; ISHIKAWA YoshieThe purpose of this study is formation of excellent surface oxide films to improve the biocompatibility on a Ti-6Al-7Nb (α+β) 2 phase-type alloy by means of anodic oxidation, involving Ca cation and hydrothermal process. Nano-tube surface film was generated even there was some difference in tube diameter between α and β phases. And Ca was incorporated into the nano-tube structure. Micro-arc oxidation process in the chemical solution containing Ca ion made the surface film containing Ca cation. We find that ingredients of the chemical solutions affected phases in the oxide film and the structure of the interface and defects.Hydrothermal treatment for improvements in the strength and functions of anodic oxidation films formed on the biomaterial titanium alloy.Japan Society for the Promotion of Science：Grants-in-Aid for Sc...See More
- Synthesis of TiO_2 Nanocrystals with Specific Crystal Plane on the Surface and Characterization of Their Photocatalytic and Dye-Sensitized PropertiesJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 2008 -2010Author : FENG Qi; TANAKA Yasuhiro; ITOH HiroshiIn this study, we developed a novel process for the synthesis of anatase-type TiO_2 nanocrystals with specific crystal plane on the crystal surface using layered titanate nanosheets as the precursor and studied their photocatalytic activity and dye-sensitized solar cell performance. The TiO_2 nanocrystals with (010) plane on the surface can be prepared by hydrothermal treatment of H_<1.07>Ti_<1.74>O_4 nanosheet solution. The (010) plane presents the high photocatalytic activity and high dye adsorption amount. The results of dye-sensitized solar cell study indicate that the V_
value increases with increasing the dye adsorption amount and the J_ value increases with increasing adsorption constant. We give the quantitative relationships between the dye adsorption parameters and solar cell parameters for the first time.

Primary experimental results were as follows. 1. Density The density vs. composition curve for the Ti-Zr binary alloys slightly deviated positively from the straight baseline connecting the two points on both ends for pure Ti and pure Zr. It is noted that the degree of deviation from the straight baseline was slightly greater in the Ti-rich region compared to the Zr-rich region. 2. Hardness Hardness of the as-cast pure Ti and Zr were 157 VHN and 196 VHN, respectively. The alloying addition of 20 at.% Zr to Ti drastically increased hardness, indicating that a great deal of solid solution hardening occurred. Further addition of Zr further increased Vickers hardness up to about 370 VHN at Ti-60 at.% Zr composition. Similar solid solution hardening was observed when Zr was alloyed with Ti. However, magnitude of increase in hardness was much weaker in the Zr-rich region compared to the Ti-rich region. 3. Young's modulus and Poisson's ratio Young's modulus of pure Ti was significantly higher than that of pure Zr. By alloying Ti with Zr, Young's modulus markedly decreased and the minimum Young's modulus of about 89 GPa was obtained at the Ti-60 at.% Zr composition. On the other hand, Poisson's ratio of pure Ti was significantly lower than that of pure Zr. By alloying Ti with Zr, Poisson's ratio markedly increased and the maximum Poisson's ratio of about 0.343 was obtained at the Ti-60 at.% Zr composition.Development of Titanium Alloys with Low Elastic Modulus and High Corrosion Resistance designed on the Basis of Quantum Chemistry TheoryJapan Society for the Promotion of Science：Grants-in-Aid for Scie...See More

- New strategy for developing surface-treated functional titanium based on nano-structure and electronic state analysesJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 2003 -2005Author : TANAKA Yasuhiro; HISATSUNE Kunihiro; KUWANO Noriyuki; SHIRAISHI Takanobu; SAWASE Takashi; TAKUMA Yasuko1.Binding enhancement mechanism of the metal bonded porcelain with the Au sputter-coated titanium was investigated using transmission election microscopy. The deficient layer on the titanium side disappeared by the Au sputter coating. Without the Au coating, titanium atoms is considered to diffuse on the porcelain side through the reaction layer at the fused interface. On the other hand, gold has a strong affinity for titanium, so the gold layer is considered to hinder titanium diffusing into the porcelain and oxygen diffusing into the titanium. 2.The results of the electron energy loss spectroscopy (EELS) well explain the fused interface structure and the crystal structure. 3.Ion plating is applied to one of titanium surface treatment methods. Ionized titanium was introduced by an electron beam melting and Ar RF plasma. The thickness of the ion-plated titanium film was about 100 nm and the crystal grain size in the film was around less than 10 nm. Cross-sectional TEM observation was performed. 4.Acrylic resin rods at about 1 mm in diameter were subjected to the Ti ion plating and we prototyped titanium implants for animal trials. The benefit of this implant is that we've been able to slice the titanium implant with surrounding tissue using microtome. The trial implant was placed into the middle portion of the diaphysis of the left femur in mouse. After 1-4 days operation, immunohistochemistry with fibronectin (FN) antibody was performed. The results suggest that Plasma FN regulates bone formation.New strategy for developing surface-treated functional titanium based on nano-structure and electronic state analysesJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDat...See More
- New evolution of magnetic attachment system applying iron-platinum magnetic alloysJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 2002 -2004Author : HISATSUNE Kunihiro; FUKUNAGA Hirotoshi; SHIRAISHI Tananobu; SAWASE Takashi; TANAKA Yasuhiro; MIURA Eri1.We investigated adhesion between the iron-platinum alloy and denture resin using primer. The shear bond strength using VBATDT included primer was almost the same strength of the control sample that was not treated by any primer. After 10000 times thermal cycle (10000TC), the shear bond strength decreased to 1 MPa. The bond strength using 4-META included primer was twice strong as the control sample. After 10000TC, the bond strength using 4-META included primer decreased to the same as the 10000TC control sample. In the cases of MDP or MEPS included primers, the bond strengths were over 15 MPa and three times as strong as that of the control sample. In addition, after TC10000, the bond strength using MDP included primer was almost the same before thermal cycle, although the MEPS treatment suffered from the thermal cycle. The most appropriate primer for bonding iron-platinum alloy to resin is considered to include MDP monomer. 2.We investigated wear resistance of the iron-platinum magnet. Wear of the iron-platinum magnet was the same of the Co-Cr alloy and a twentieth as much as those of the gold alky and the silver-palladium-copper-gold alloy. It seems that the excellent wear resistance is obtained by the aging process to generate the ordered L1_0 phase that is necessary for the hard magnetic properties. 3.We observed microstructure of the iron-platinum thin film fabricated by RF sputtering for the application of micro-machine. Remanence enhancement occurred by aging at 50℃. TEM observation unveiled that the microstructure was intermingled with the fcc disordered phase and the L1_0 ordered phase within a 50nm area. Exchange interaction between these phases seemed to lead the remanece enhancement.New evolution of magnetic attachment system applying iron-platinum magnetic alloysJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 2002 -2004 Author : ...See More

Liquidus and solidus temperatures were determined from DSC data. Spectrophotometric colorimetry was performed to investigate the optical properties and to quantify the tarnish resistance in the 0.1% Na_2S solution. Principal results obtained are as follows. 1. In the alloys with the same Au content, both liquidus and solidus temperatures lowered with increasing Cu content. Solidification temperature range became narrow with increasing Cu content. 2. In all the experimental alloys, spectral reflectance was high in the long-wavelength region and very low in the short-wavelength region due to the effective absorption of light. 3. In the alloys with the same Cu content, the absorption edge systematically moved towards longer wavelength direction with increasing Au content. Simultaneously, spectral reflectance in the long-wavelength region slightly decreased with increasing Au content. Owing to these systematic variations of spectral reflectance curves, chromaticity index b^* (yellow-blue) apparently increased, giving a gold tinge to the alloy. 4. In the alloys with the same Cu content of 15 at.% or 20 at.%, tarnish resistance of the alloys in the 0.1% Na_2S solution was markedly improved with Au content. 5. Among the three coordinates, L^*, a^*, b^*, in the CIELAB color space, decrease in L^*-value effectively affected the color change, ΔE^*, of the material in the tarnish test solution.Development of Dental Alloys alternative to Ag-Pd-Cu-Au AlloysJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 2001 -2002 Author : SHIRAISHI Takanobu; ...See More

- A Study for Low Carat Gold Alloys with Age-hardenability at Intraoral TemperatureJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 1999 -2001Author : HISATSUNE Kunihiro; TANAKA Yasuhiro; SHIRAISHI Takanobu; TAKUMA Yasuko; MIURA EriGold alloys are one of the most useful materials in dental treatment. The required strength is an application of heat treatment wife age4iardening,The hardening is controlled by the formation of ordered phase with L1_0 structure. However, there appears one serious problem of the. deformation on prosthetics, because the L1_0 is different from the matrix phase (fcc) in crystal structure. The purpose of the present study is to clarify the possibility for use of L1_2 phase (fcc) having the same structure. As an L1_2 structure, Cu_3Au and CuAu_3 were selected. Four binary and six ternary alloys were prepared by vacuum-melting in a high-frequency induction furnace. After the solution treatment, two modes were employed, namely anisothermal and isothermal annealings. Th age-hardening behaviors were examined by electrical resistivity measurements, hardness tests, X-ray diffraction and transmission electron microscopy. The main results were as follows ; (1) It is difficult for only L1_2 phase to obtain appropriate strength for dental prosthetics. Partial introduction of the L1_0 phase (CuAu I) is demanded for the required strength. (2) Remarkable age-hardening was due to the formation of the CuAu I ordered phase in the Au_3Cu ordered matrix. (3) Three types of phase transformation in the grain interior from the disordered phase to the equilibrium phases (L1_0 + L1_2) were detected during the isothermal aging. The difference can be interpreted in terms of the free energy.A Study for Low Carat Gold Alloys with Age-hardenability at Intraoral TemperatureJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 1999 -2001 Author : H...See More

The alloy containing 10wt% Fe showed low corrosion resistance compared with the commercially pure titanium. These alloy indicated the hardness value similar to that of dental Co-Cr alloys. The machaniblity of these alloy were very poor compared to that of dental casting alloys. Especially these alloy demonstrated low rate of machinability compared with the commecially pure titnium. Is is to be desired that the developed titanium alloy shows 1.5 or 2 time greater hardness than commercially pure titanium. The addition of Cr and Mo in titanium showed approximately 300 VHN of hardness and this value is similar or superior to the hardness of dental casting gold alloys. The titanium alloy added with Ag indicated the lower hardness (approx. 200 VHN) than the dental casting gold alloys. The addition of Ag in titanium demaontrated the vaporization of Ag in the casting machine during casting and indicated the possibility of damage for the casting machines. The addition of Cr and Co in titnanium deduced the reactivity between the investment material and the alloy surface. All of the titanium alloy indicated low machinability comapred to the commercially pure titanium.

Effects of laser irradiation and APF on dentin remineralization Demineralized root dentin samples were treated with APF and/or laser- irradiated and then remineralized for 2 weeks. Mineral profiles were evaluated by microradiography. Results showed that 1) In the group of APF(-)Laser(+), hyper-remineralization was inhibited and the lesion depth was significantly recovered compared with the control group. 2) APF treatment promoted remineralization and inhibited the formation of hyper-remineralization. 3) In the group treated with APF, there was no effect of laser irradiation on dentin remineralization. 2. Remineralization of dentine demineralized by EDTA Root dentin samples were treated with EDTA for 15, 30, 120 min and remineralized for 2 weeks with or without 2 ppm fluoride. Results showed that If fluoride was not present in the remineralizing solution, no remineralization occurred. Two ppm of fluoride enabled dentin remineralization at the lesion front. 3. Relationship between mineral distribution in dentin lesion and subsequent remineralization 1) In the no mineral lesion type, high level of fluoride accelerated remineralization throughout lesion although low level of fluoride promoted remineralization just at the lesion front. 2) In the softened lesion type, no effect of fluoride on remineralization was observed. 3) In the subsurface lesion, high level of fluoride promoted the total remineralization mainly due to hyper-remineralization on the original surface.Research on Dentin Remineralization and HypersensitivityJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 1997 -1999 Author : IIJIMA Youichi; TANAKA Yas...See More

It is very important to understand nature of the interface. The investigation of the formation process and the fundamental structure within the interface between metal and ceramics is an important requirement for improving the bonding technique. Two signiticant conclusions were mainly obtained as follows ; 1. It was constructed how to produce better specimen for high resolution transmission electron microscopic observations on the interface of the composite materials. This technique is very effective to perform a direct observation. Especially, the present study was employed for the interface of the materials with remarkably different mechanical properties. 2. It is determined that the dental gold alloy and the dental porcelain were directly bonded without any intermediate layrs. This is new evidence for the system. It means that previous conclusion was rejected. The previous data were not obtained at interface itself but at the vicinity. The EPMA data which were previously obtained, correspond to the information in micrometer scale, while the present HREM data were obtained in nanometer scale.Characterization of fuzzy interface in biomaterials by HREMJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 1995 -1997 Author : HISATSUNE Kunihiro; HAS...See More

Ion implantation, plating and mixing techniques were employed. Ion implantation improved remarkably the corrosion resistance. A superlattice structure was formed by annealing after the implantation. However, it is a problem for the implantation surface to have rough surface. Ion plating produced a homogeneous coating surface and improved the strength and corrosion resistance. We got best results by ion mixing technique, which corresponds to use at the same time ion implantation and ion plating. This method has an additional merit which we can control the thickness of surface modification. During the present work, we also discuss the ordering mechanism in CuAu I,the formation of which is expected by annealing after the surface modification in dental gold alloy. The ordering proceeded in three stages (I,II and III). Stage I corresponds to the ordering by migration and annihilation of quenched-in excess divacancies. This ordering stage will be available on ion mixing treatment sample, because of be possible at room temperature.Surface Modification in Dental Alloys by Ion EngineeringJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 1994 -1995 Author : HISATSUNE Kunihiro; BABA K...See More

- Elucidation of Characteristic Strengthening Mechanisms in Dental Gold Alloys by High Resolution Electron MicroscopyJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 1991 -1993Author : YASUDA Katsuhiro; BABA Kohmei; TANAKA Yasuhiro; UDOH Koh-ichi; HISATSUNE KunihiroAge-hardening characteristics and associated phase transformations were studied by means of electrical resistivity measurements, hardness tests, X-ray and electron diffraction, transmission electron microscopy and scanning electron microscopic observations in an AuCu-14at.%Ag pseudobinary alloy. The critical temperature for ordering was determined to be 650 K and the spinodal temperature was estimated to be 640 K.Age-hardening at 623 K was attributed to nucleation and growth processes of the AuCu II' metastble ordered phase even though the ageing temperature was just below the spinodal temperature. While hardening in the lower temperature range took place at two stages, the former was due to spinodal decomposition and the latter was brought about by ordering of AuCu I' and/or AuCu II' metastable phases depending on ageing temperature. The age-hardening mechanism of a commercial dental gold alloy containing platinum and palladium (Au-32at.%Cu-7.6at.%Ag-6.2at.%Zn-3.8at.%Pd-3.5at.%Pt) was also studied. The sequence of phase transformations during isothermal ageing below the critical temperature of ordering, Tc=825 K, was described as follows : disordered solid solution alpha_0 (fcc)--metastable AuCu I' ordered phase (fct) + metastable alpha_2' disordered phase (fcc)--equilibrium AuCu I ordered phase (fct) + equilibrium alpha_2 desordered phase (fcc). High resolution electron microscopic observation revealed that the hardening was due to the introduction of coherency strain at the interface between the AuCu I' ordered platelet and the surrounding matrix. The spinodal ordering which was predicted by the CVM was confirmed by means of TEM, SAED and XRD examinations in the equiatomic AuCu alloy using direct ageing. The coherent phase boundary, Tc', and the spinodal ordering temperature, Ts, were identified from differences of microstructural features and changes in XRD patterns during ageing at verious temperatures. The Tc' and Ts were determined to be 648 K and 630 K.Elucidation of Characteristic Strengthening Mechanisms in Dental Gold Alloys by High Resolution Electron MicroscopyJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate ...See More

- Characterization of Interfaces in Dental Alloys by HREMJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 1991 -1991Author : YASUDA Katsuhiro; TANAKA Yasuhiro; UDOH Koh-ichi; HISATSUNE Kunihiro; VAN LANDUYT Joseph; VAN TENDELOO GustaahThe eventual purpose of the present research project is the tailoring of new dental alloys by scientific designing principle which is governed by microstructural features of the alloy crystals based on an interfacial characterization approach. Identification of phases formed by phase transformation in a series of alloys from 50at. %Au and 50at. %Cu to Ag was studied by means of electrical resistivity, X-ray diffraction, conventional transmission electron microscopy and high resolution electron microscopy combined with selected area electron diffraction technique. Addition of Ag to AuCu alloy reduced the critical temperatures of ordering of AuCu II and AuCu I at the composition region outside of the Ag-Cu binodal line in AuCu-Ag pseudobinary system. A disordered solid solution of f. c. c. alpha_0 phase which was predicted from the phase rule was found adjacent to a tip of microtwin- platelets when they were in contact with another orientation variants of the microtwin platelets as an inevitable consequence of strain accommodation in AuCu-1.5at. %Ag and AuCu-3at. %Ag alloys. Although an adjacent region of a tip of microthin platelet by arcuation in AuCu-3at. %Ag alloy, such arcuation was never observed at the adjacent region of microthin platelet tip contacted with another variants of microthin platelets in AuCu-1.5at. %Ag alloy. A structural configuration of nucleous formed by ageing was analysed and depicted as a composite nucleous consisted of AuCu II and alpha_0 phases from HREM images. The boundary between alpha_0 + AuCu II and AuCu II also sloped downward for Ag content to the binormal K line. In Au-50at. %Cu stoichiometric composition alloy, the occurrence of spinodal ordering at around 630K was implied from difference in heat treatment mode between a direct ageing from disordered solid solution and tempered ageing after quenching. Ordering wasinduced by nucleation and growth mechanism at a temperature above 630K, while the ordering was originated homogeneously from the mechanism of spinodal ordering.Characterization of Interfaces in Dental Alloys by HREMJapan Society for the Promotion of Science：Grants-in-Aid for Scientific ResearchDate (from‐to) : 1991 -1991 Author : YASUDA Katsuhiro; TANAKA Ya...See More
