Increasing resistivity of copper with scaling and rising demands on current density requirements are driving the need to identify new wiring solutions for deep nanometer scale VLSI technologies. Metallic carbon nanotubes (CNTs) are promising candidates that can potentially address the challenges faced by copper and th…
This work is centered on the study of the corrosion inhibition of copper in 1 M HNO3 by N-phenyl oxalic dihydrazide (PODH) and oxalic N-phenylhydrazide N-phenylthiosemicarbazide (OPHPT) synthesized in our laboratory. The inhibition efficiency obtained by chemical (weight loss) and electrochemical (potentiodynamic pol…
Amide derivatives of L-alanine and ε-caprolactam were readily obtained on diamine-functionalized oxidized single-walled and pristine multi-walled carbon nanotubes through a one-step direct amidation reaction, which employs thermal activation at 160–200 °C instead of chemical activation, avoids the use of organic solve…
The stress that acts on the core by installing a stator in a frame influences the performance of a motor. To reflect this influence in the equipment design, the stress dependence of the magnetic property was examined for non-oriented electrical steels, which are the core materials. This time, the stress dependence of…
The dependence of the nearest neighbor magnetic interaction, JAB, as a function of geometry for [Mn(porphyrin)][TCNE] materials has been evaluated by the results of CASSCF, CASPT2 and B3LYP calculations. The B3LYP results were validated for seven representative [Mn(porphyrin)][TCNE] molecule-based magnets and were fou…
Mechanically robust, hollow carbon nanotube composite spheres that are permeable to large chemical species were prepared by a layer-by-layer assembly and templating technique.
Extraordinary high degrees of polar order can be achieved by a rational design that involves the polar stacking of parallel beloamphiphile monolayers (PBAM). This strategy is exemplified by the acetophenone azines MCA (4-methoxy-4'-chloroacetophenone azine) and DCA (4-decoxy-4'-chloroacetophenone azine). The beloamphi…
Comparative studies of the pulsed laser ablation of graphite in 20mTorr of N2 using both 15ns and 450fs pulses at a wavelength of 248nm are reported. Emissions from the resulting ablation plumes, and from collisions with ablated material and the background N2 gas molecules, have been investigated by wavelength-, space…
It is well known that Si and Mn, the basic alloying elements for steel materials, are susceptible to oxidation and form oxides on the steel surface easily, which has a great influence upon the surface performance of steel sheets such as phosphatability. In recent years, on the other hand, the cold rolled steel sheets…
Abstract: Heterogeneous ruthenium catalysts supported on silica from rice husk ash (RHA-Ru) was prepared by precipitation using an aqueous solution of metal salt in 3.0 M HNO 3 . The effect of calcination at high temperature upon the surface and bulk structure of the catalyst precursor has been investigated. X-ray dif…
A device architecture is proposed to improve the linearity of barium strontium titanate (BST) capacitors while maintaining the tunability and the quality factor. Thin-film parallel plate capacitors are fabricated utilizing the proposed architecture. The measurement results successfully demonstrate the effectiveness of…
The mechanism of oxidative polymerization of diphenylamine is considered. The kinetic study of diphenylamine polymerization and of the structure and molecular-mass characteristics of the reaction products has shown that the degree of oxidation of intermediates plays the key role in polyrecombination. The relationship…
A post-synthetic process to create functionalized mesoporous dendritic silicas with a high density of tertiary amino groups is presented. Polyamidoamine periodic dendrimers up to the second generation were grown inside the channels of mesoporous hybrids. The results demonstrate that the novel polyamidoamine dendritic…
As-deposited films of multilayered polyelectrolytes are considered to be non-equilibrium structures. Due to the strong attraction between oppositely charged polyions, polyelectrolyte interdiffusion is thought to be suppressed during the adsorption process. Equilibration is promoted by a decrease of the electrostatic a…

キトサンを60Coからのγ線で照射し, 植物生育促進効果を示した100 kGyの放射線分解産物を分離し, 分子量が1～3kDaのフラクションがダイズ, オオムギに高い植物生育促進効果を示すことがわかった。このフラクションの生育活性は分離前 (50mg/L) よりも低い濃度 (20mg/L) で生育を促進することが示された。また, ファイトアレキシンに関与するフィニルアラニンアンモニアリアーゼ (PAL) とキチナーゼ活性を増加させた。放射線分解産物で得られた本フラクションは植物生育のみならず, 防護剤としての作用も示唆された。またこのフラクションはダイズの収量を増加させる効果も示した。
For diesel engines, changing the fuel composition is an alternative route towards achieving lower emission levels. The potential of oxygenated fuels to significantly reduce particulate matter emissions has already been demonstrated earlier. In this study, this research has been extrapolated towards lower emission leve…
We examine the stability of lamellar stacks in the presence of an electric field, , applied normal to the lamellae. Calculations are performed with self-consistent field theory (SCFT) supplemented by an exact treatment of the electrostatic energy for linear dielectric materials. The calculations identify a critical el…
