Surface Mechanical Attrition Treatment (SMAT) effectively activates the surface of pure Al and, therefore, lowers the subsequent Packed Powder Diffusion Coating (PPDC) treatment temperature from 600 °C to 560 °C. Although the nanocrystalline grains generated by SMAT in the top surface layer are coarsened during the su…
A physical vapour condensation method is used to synthesise the nanostructures of ZnO. These nanostructures are fabricated by resistive heating of Zn powder at a temperature of 400°C in the presence of oxygen and argon gases under a vacuum of order of 10−6 mbar. The transmission electron microscope (TEM) images sugges…
The water entry problem is considered as a classic problem which has a research history of more than 70 years, the water‐entry process for projectiles with different nose will be significant for related application and experimental design. In this paper, a series of numerical simulations were conducted to study the wa…
Crack nucleation along deformation twin boundary has been investigated in an Fe-20%Cr alloy. The deformation twins were introduced by compression test in liquid nitrogen. Push-pull fatigue tests on the twinned specimens were carried out at room temperature. Two kinds of cracks were detected in the vicinity of the twin…
The Molten Salt Reactor (MSR) is one of the six Generation IV systems capable of breeding and transmutation of actinides and long-lived fission products, which uses the liquid molten salt as the fuel solvent, coolant and heat generation simultaneously. The MSR neutronics, such as the distribution of the delay neutron…
Structural studies of biological macromolecules are severely limited by radiation damage. Traditional crystallography curbs the effects of damage by spreading damage over many copies of the molecule of interest in the crystal. X-ray lasers offer an additional opportunity for limiting damage by out-running damage proce…
テトラメトキシシラン(TMOS)およびヘキサメチルジシロキサン(HMDSO)をプリカーサとして用いて，大気圧低温アルゴンプラズマジェットによる化学蒸着(CVD)を行い，ガラス状薄膜を作製した．また，プラズマ照射による基板温度および，プラズマジェットの安定性の変化を観察するとともに，作製した薄膜の FT-IR，XPS 分析を行った．その結果，基板の温度上昇はほとんど見られなかった．プラズマジェットはアルゴンに添加する窒素流量が多いほど高電圧においても安定なグロー放電状になる一方，プラズマの発光強度は低下した．TMOS をプリカーサとして用いたとき，炭素成分が 10 mol%以下のガラス状薄膜が生成し，その膜厚は照射時間に比例した．さ…
Much interest has been taken in crystallizing silver nano-particles on metal oxide, for the purpose of using their composite as a noble catalyst for synthetic organic reactions. We studied crystallization of silver nano-particles onto TiO2photocatalyst with the help of reducible action of ethanol. Reducible action of…
Giant magnetostrictive material (GMM) is fabricated by electromechanical transformation with large magnetostriction and an electro-mechanical coupling factor. Therefore, GMM can be use to make a giant magnetostrictive actuator. However, because the thermal expansion (linear expansion) coefficient of GMM is 12 ppm/°C,…
We investigate thermal transport in water/carbon nanotube (CNT) composite systems using molecular dynamics simulations. Carbon-carbon interactions are modeled using the second-generation REBO potential, water-water interactions are modeled using the TIP4P potential, and carbon-water interactions are modeled using a Le…
The effect of titanium particle morphology on the shock sensitivity of titanium‐silicon powder mixtures has been investigated experimentally. The powder mixtures were tested in a planar recovery capsule, with the shock loading produced by a high explosive booster charge placed on top of the capsule and a PMMA attenuat…
This paper presents the results of laboratory investigation on the corrosion of oil alkyd-coated steel plates with unpainted defects under marine environment. Oil Alkyd paint-coated divided steel plates, (30mm × 30mm) composed of 9 pieces of 10mm × 10mm steel elements with different types of defects, were submerged in…
Charge-carrier heating and the carrier concentration dependence on electric current in quantum-well laser heterostructures have been studied under conditions of spontaneous and stimulated emission. Intersubband absorption in tunnel-coupled quantum wells has been investigated under charge-carrier heating by a lateral e…

Multiscale polymeric composite laminate reinforced by carbon micro-fibers (CFs) and carbon nanofibers (CNFs) is fabricated via an in-house developed prepreg and vacuum bag/compression molding process. The multiscale fiber system is expected to form a multiscale fiber reinforcement network inside the composite. As a re…
An equation is obtained for the order parameter ξ of the spin-Peierls phase transition in a light field. This equation is used to derive the expressions for the frequency ν of the photogenerated longitudinal optical phonon mode and the time τ of the photoinduced phase transition. Numerical values of the quantities ν a…
In this work we report the optical characteristics of carbon nitride films produced by a KrF excimer laser ablation technique. The ablated materials were collected on different wafers, glass and porous silicon for different N2 pressures (0.1-0.5mbar). The thin films were synthesized at room temperature. The deposited…
From the CoCl 2 -1-amino-8-hydroxynaphthalene-2,4-disulfonic acid-benzoin (or benzaldehyde and its para - and ortho -hydroxy derivatives), complexes of the composition C 48 H 38 K 2 N 2 O 18 S 4 Co, C 17 H 17 ClKNO 11 S 2 Co, C 17 H 16 KNO 11 S 2 Co, and C 34 H 24 K 2 N 2 O 16 S 4 Co 2 were isolated. These compounds w…
