This article is dedicated to late Dr. Ito for his distinguished invention, fantastic technology, and warmhearted humanityRefractive index lithography was performed on polymer films consist of a photo-acid generator (PAG), t-BOC-protected naphthazarine as an acid chromic dye. The key reaction is the chemically amplifie…
Electrical properties of Al y Ga 1–y N/Al x Ga 1–x N/AlN/GaN structure are investigated by solving coupled Schrödinger and Poisson equation self-consistently. Our calculations show that the two-dimensional electron gas (2DEG) density will decrease with the thickness of the second barrier (Al y Ga 1–y N) once the AlN c…
Using a 135-kHz induction-coil-type electrodeless lamp system offers several advantages including high efficiency, long life, and low resource consumption. To optimize the lamp dimensions, electron density was analyzed by the complex finite element method for magnetic fields and plasma. Magnetic flux density, current…
MoO2 nanotube with rectangular cross sections can be prepared on Mo substrates by using an O2-C2H2 combustion-flame method [Jpn. J. Appl. Phys. 44 (2005) L449]. We have investigated the growth behavior of the nanotube in detail by using scanning electron microscopy and energy dispersive x-ray microanalysis. The precur…
Electric force spectroscopy on an atomic force microscope has been used to determine the electric field distribution in the electric double layer at a liquid-crystal–glass interface. The separation-dependence of the electric force has been studied inside the liquid crystal interface, and screening of the surface elect…
Non-equilibrium solidification of undercooled Ti-Al-Nb melts with compositions around the border of the α-Ti/β-Ti phase domains are investigated using the electromagnetic levitation technique. Detailed thermal histories of rapid recalescence processes acquired with a high time-resolution by a fast responding photo-dio…
With the enhancement of environmental awareness, controlling oil mist in machinery processing workshop has become more and more important. Nanometer titanium dioxide (TiO2) photocatalysis material can treat with manifold pollutants, which is widely applied with its merits of decomposing products sufficiently and no se…
Copper nanorods and triangular nanoplates have been successfully generated by via a simple solution-phase approach by reducing CuCl2 with L-ascorbic acid (AsA) in aqueous solution in the presence of cetyltgrimethlammonium bromide (CTAB). The formation of self-assembled microstructures of CTAB molecules in aqueous solu…
Abstract The paper presents research results on curing two recently synthesized liquid crystalline epoxy materials with selected amines. The process of cross-linking, the final product of curing, and the pure monomers were examined using polarizing optical microscopy (POM), differential scanning calorimetry (DSC), and…
Al–Mg alloys treated by continuous rotation evolutional control (CREO) were anodized and colored by alternating current electrolysis at 10 V in sulfate solutions containing Cu, Sn, Ni, or Co at 303 K. Electrolysis turned the anodized Al–Mg alloys to rufous (Cu), yellow to gold (Sn), or reddish brown (Ni and Co). Their…
The effect of colloidal silica (SiO2; CS) addition on the formation of porous spherical α-calcium orthophosphate (α-Ca3(PO4)2; α-TCP) agglomerates has been examined. The starting powder was prepared by the spray pyrolysis of calcium phosphate (Ca/P ratio = 1.50) solution containing 0.9 mol·dm-3 Ca(NO3)2, 0.6 mol·dm-3…
A method is demonstrated of making interference filters fabricated using a layer of metal oxide deposited by a new atmospheric pressure atomic layer deposition (ALD) technique. By depositing different thicknesses of metal oxides between reflecting layers, filters with various spectral characteristics can be made. A me…
The aim of this paper is to show how efficient mathematical models can be in simulating situations that are apparently distant from one another. The works of M. C. Escher and Buckminster Fuller are used as starting points for the exploration of the first applications of non-Euclidean geometry to architecture. The inve…
Development of thermally durable SiC molds enabled us to imprint fine periodic structures onto a oxide glass surface. Antireflection lenses, quarter wave plates operating operate in visible wavelength region, could be fabricated.
In order to obtain precise and correct dynamic stress-strain behavior for steel plate, the split Hopkinson (Kolsky) bar method or the one bar method has been adopted as a testing method. In these two methods, a dynamic load transducer is the thin steel bar (s). On the input and output bars, typically two or four strai…
Surface modification of the carbon nanotubes is important for their application in various fields. In this study, multiwalled carbon nanotubes (MWCNTs) were grown on cobalt catalyst layer (3 nm thickness) sputtered on a silicon substrate using Microwave Plasma Enhanced Chemical Vapor Deposition (MPECVD) system. The as…
The experimental results on neutron-irradiated reactor pressure vessel (RPV) steels have revealed grain boundary segregation of phosphorous (P) due to neutron irradiation, which may lead to intergranular fracture. Because of the lack of experimental database, however, the dependence of the segregation on variables suc…
Mean-field study of the stripe structures is conducted for a hole-doped Hubbard model. For bond-directed stripes, the Fermi surface consists of segments of an open surface and the boundaries of the hole pockets which appear in the diagonal region of momenta under certain conditions. Segments of the first type are due…
Al 67 Cu 20 Cr 13 and Al 75 Cu 10 Cr 15 alloys were produced by mechanical alloying from elemental powders. As-milled samples consist of the initial elemental phases. Phase transformations at heating were analyzed by differential scanning calorimetry and X-ray diffraction analysis. Annealing of as-milled powders in th…
Proton exchange membrane (PEM) fuel cells are favored in many applications due to their simplicity and relatively high power density. However, there has been a lack of understandings of the fundamental mechanisms of assembly and manufacturing induced phenomena and their influence on performance and durability. This pa…
