Magnetic anisotropy properties of amorphous ferromagnetic CoSiB/Pt multilayers with perpendicular magnetic anisotropy (PMA, K(u)) were systematically investigated as a function of CoSiB layer thickness (t(coSiB)) and Pt layer thickness (t(Pt)). In two series of [CoSiB t(coSiB)Pt t(P1)]5 multilayers, the perpendicular…
In the authors' previous studies, the theoretical model of ultrasonic wave velocity propagating in plastically deformed solids has been proposed by one of the authors and successively verified experimentally. Then, deformation localization was analyzed by adopting the proposed theoretical model. The onset of localizat…
Porous collagen matrices containing chlorhexidine digluconate (CHXD) were obtained by freeze-drying of three series of 1.1% collagen hydrogels having the pHs 3.8, 7.4 or 7.4 plus 0.15% glutaric aldehyde (GA) reported to the collagen from hydrogel, each series containing 0, 0.02, 0.05 or 0.10% CHXD reported to the amou…
As an integration of Pb-free ferroelectrics with wide-gap semiconductors, (Pr, Mn)-codoped BiFeO 3 (BPFM)/B-doped diamond layered structure was fabricated on a diamond substrate. B-doped diamond films were homoepitaxially grown on (100) diamond substrate using microwave plasma-enhanced chemical vapor deposition. Then,…
Long term optical properties of fluorescent I-III-VI semiconductor nanoparticles and its solid solution dispersed in the methacrylate resin were tested under various conditions aiming at their use as wavelength converters. The ZnS-AgInS2 solid solution nanoparticles, which we developed recently, have less stability ag…
超臨界CO2-エントレーナー法による多孔性シリカからのテンプレート剤抽出について，操作因子やエントレーナー種の最適化および抽出メカニズムの解明を目的とし，温度80℃，圧力8–14 MPa，エントレーナーとしてメタノール，エタノール，1-プロパノールを用いて抽出時間1–7 hの条件下で実験を行った．その結果，2種のテンプレート剤のうちEO20–PO70–EO20トリブロックコポリマー（EPE）が先に抽出された後，Cetyltrimethylammonium hydroxide（CTAH）が抽出されるメカニズムを明らかにした．続いて抽出圧力の影響の検討から，ある圧力で除去率が極大値を示すことがわかり，これは系内の相状態から説明可能であ…
Mechanosensitive ion channel transduce physical stresses to cells by the response of electro-chemicals exchange. The purpose of this study was to improve understanding of ion channel inhibition process by SWCNTs. PatchDock and FireDock results suggest that the SWCNTs interact with the extracellular domain of the ion c…
Dye-sensitized solar cells based on low-viscosity phosphonium ionic liquids having a methoxymethyl group, triethyl(methoxymethyl)phosphonium bis(trifluoromethylsulfonyl)amide and triethyl(methoxymethyl)phosphonium dicyanamide, as their electrolytes have been successfully fabricated. The photo-energy conversion efficie…
Temperature distribution in a fuel cell significantly affects the performance and efficiency of the fuel cell system. Particularly, in low temperature fuel cells, improvement of the system requires addressing the heat management issues, which reveals the importance of developing thermal models. In this study, a 3D num…
As a new catalyst support, powdered diamond was first investigated. Although diamond has been considered to be a stable material, the surface carbon was found to react to give C–H and C–O–C or C=O bonds by hydrogenation and oxidation. Oxygen treated diamond (O-Dia) was evaluated as a catalyst support material, which w…
In this study, recent developments regarding the modeling of microstructural evolution during recrystallization are reviewed, and this paper highlights a unified theory for continuous and discontinuous annealing phenomena by means of the subgrain growth mechanism. In Sec. 3.2, the mean field analysis based on the unif…
We report here, the synthesis and characterization of Aluminum (Al) doped Mg2TiO4. Magnesium ortho titanates spinel {with composition Mg2TiO4; tetrahedral site A = Mg and octahedral site B = Mg, Ti (equal amounts)} for general formula AB2O4 has been synthesized by solid‐state reaction technique. The formations of tita…

SBA-15 mesoporous materials were successfully prepared by the conventional hydrothermal method and used as the support for TiO2 loaded SBA-15 photocatalysts. The synthesized materials were characterized by XRD, PL, FT-IR, BET and TEM. We also examined the activity of these materials as photocatalysts for the decomposi…
Hard clams of the genus Meretrix are known to excrete a long, thick cord of mucous from the base of their siphons, but few studies have examined the clams' use of this mucous cord as a means of passive locomotion, which may result as the cord is dragged about by water currents. In the present study of Meretrix lusoria…
The interface and thermal expansion behaviour of aluminium matrix composite (Al-3Mg) unidirectionally reinforced with continuous high modulus and high thermal conductivity carbon fibres Thornel K1100 were studied. The composite was prepared by gas pressure infiltration and was subjected to thermal cycling from room te…
The RESA-1 neutron engineering diffractometer in the JRR-3 (Japan Research Reactor No.3) at the Japan Atomic Energy Agency, which is used for stress measurements, was upgraded to realize residual stress measurements of large scaled mechanical components. A series of residual stress measurements was made to obtain thro…
Pollution free catalyst is an attractive area of current interest. The p-Aminophenol is one of the most significant catalyst, because it involves the manufacture of various pharmaceuticals. Crosslinked poly(styrene)-co-poly(4-vinylimidazole) (PSPVIM) was prepared by varying the crosslinked monomer ratio as 2% and 10%…
