The objective of the study was to quantify changes in the phase transformation behavior in NiTi SMA wires when they are heat treated and thermally cycled at zero stress. The analysis involved weight fraction evolution derived from XRD profiles using the Rietveld method and specific software. The results were compared…
In this paper, the adhesion of epichlorohydrin rubber (CHR) compounds to polyamide 6 (PA6) using a molecular adhesive (6-triethoxysilylpropylamino-1,3,5-triazine-2,4-ditiol, TES) has been investigated to clarify the relation between TES concentration on the PA6 surface and the peel strength of CHR/PA6 adherends. TES c…

The problem of a deformation of flat layer-shells of the variable thickness reinforced by fibres of a constant cross-section and working in conditions of steady creepage of all phases of a composition is formulated. The system of the resolving equations and boundary conditions matching it is analysed. The problem-solv…
Silica gel beads were coated by AgVO 3 , Ag 4 V 2 O 7 and Ag 3 VO 4 to study their photocatalytic performance.The model reaction was the decomposition of methylene blue and acetaldehyde, respectively in fluorescent and ultraviolet radiation and in darkness, as well.The photocatalytic films formed on the surface of sil…
ステンレス鋼の外面応力腐食割れ（ESCC）進展速度の温度依存性を検討した．ESCC進展速度は試験前半に大きく，時間の経過により小さくなった．試験中の最大ESCC進展速度をアレニウス則により整理し，見かけの活性化エネルギーは塩化物水溶液中のSCC進展速度と同程度であると確認した．ESCC進展速度の温度依存性はpH 1.3に調整した人工海水中でアノード分極試験を行うことにより得られる活性域臨界電流密度の温度依存性と類似の傾向が見られた．
The resistance to fatigue crack growth in a high-humidity (relative humidity RH90%–25°C) air was evaluated for 7000 series aluminum alloys with a higher strength above that of 6061-T6. The alloys, 7N01 and 7003 with temper in T6, T5 or T7, respectively, showed a medium resistance between those of 7075-T6 and 6061-T6.…
Carbon nitride has fascinating properties such as high hardness, high current density of field emission and so on. To obtain this material, generally CH4 is used as a carbon source. Therefore, to make clear the effects of the reaction gas on the preparation of carbon nitride, we tried to use C2H4 as a carbon source in…
Recently, the treatments of hepatocellular carcinoma with nano-hydroxyapatite (nano-HAP) particles have been given much attention. In this study, a new kind of nano-HAP particles was prepared by a homogenous method, and these particle diameters and their distribution, crystallization degree, chemical bondings, and mor…
Lightweight structure is an important method to increase vehicle fuel efficiency.High strength steel is applied for replacing mild steel in automotive structures to decrease thickness of parts for lightweight.However,the lightweight structures must show the improved capability for structural rigidity and crash energy…
The term “multiferroics” was originally coined for materials in which multiple ferroic orders, such as ferromagnetic, ferroelectric, and ferroelastic orders, coexist simultaneously. In recent years, some classes of multiferroics where magnetic and ferroelectric orders coexist have been attracting much attention from b…
O ne of the most important aims of formulation development for a poorly soluble new chemical entity (NCE) or active pharmaceutical ingredient (API) is to enhance bioavailability. For orally administered compounds, this can be broadly assessed by knowing the solubility and the permeability of a compound. The Biopharmac…
Lactoperoxidase (LPO) which is an enzyme of the mammalian peroxidase family , is known as an antibacterial enzyme, and it can be used as a biopreservative agent in food, feed specialties, cosmetics and related products.
Starting with the rigorous expressions, derived previously for the generalized transport coefficients of a multicomponent fluid, we obtained several exact relations for partial conductivities of ionic charge-asymmetric mixtures. For a simpler case of a charge-symmetric binary mixture such kind of relations was discove…
A packed bed reactor consisting of spherical catalyst particles in a tube was simulated numerically. The steady state pseudo- heterogeneous model consisted of a pseudo- continuum representation for the heat and mass transfer in the reactor tube. The reaction source terms were evaluated by explicitly solving a 1D spher…
The density and the surface tension of the binary tellurite melts, (M2O-TeO2 M=Li, Na and K) were measured. We investigated the thermal and compositional dependences of the properties. It was found that the density and the surface tension of the binary tellurite melts decreased with increasing temperature and M2O cont…
Multi-interlayer of Ti/Cu/Ti was used to join TiC-Al2O3 composite ceramics with W18Cr4V tool steel. Bonding was performed at 1130 C for 1 h with a pressure of 15 MPa. The TiC-Al2O3/W18Cr4V diffusion bonded joint was examined by means of optical microscope, scanning electron microscope (SEM) and electron probe microana…
Various resins (adherends) were treated with a corona discharge apparatus to give OH groups on the surfaces. The reaction of obtained OH group-linked resins and 6-triethoxysilylpropylamino-1,3,5-triazine-2,4-ditiol (TES) produced TES-linked resins. Direct adhesions of halogen-containing rubbers (adhesives) to TES-link…
For the main purpose of manipulating the functions of molecules, researchers have made great achievements on photo responsive molecules using light as a trigger. Light has become a promising scientific tool due to it being a clean and non invasive external stimulant. By attachment of photoresponsive moieties to mole…
Profile accuracy of spherical ?-TCP ceramics (artificial bone units) was improved by a precision fabrication method named “hydro-casting.â€? Hydro-casting shapes ?-TCP slurry into spherical shape by dispensing definite quantity of ?-TCP slurry in an oil and fixing the slurry’s shape by two-stage gellation. Resulti…
