The diffusion coefficient of Cu in (Ti, Zr)N was measured by X-ray diffraction (XRD) and four-point probe (FPP) analyses after annealing Cu/(Ti, Zr)N/Si multilayered samples in the temperature range of Cu diffusion in (Ti, Zr)N had components from both the grain boundaries and the lattice based on diffusional analysis…
The application of ATP-loaded liposomes has been shown effective against ischemic damage in several tissues. In this study, we have prepared ATP-containing liposomes capable of specific recognition of component (myosin) specific for ischemic myocardium. ATP-containing immunoliposomes specific towards cardiac myosin we…
A series of optimised materials in the family with parent compound La(2)Mo(2)O(9) have been studied using the isotope exchange depth profile technique and SIMS analysis. The data collected indicate that the oxide ion diffusion coefficients in both the parent compound and optimised materials are significantly higher th…
Optical vibrations of the lattice and the electron–phonon interaction in polar ternary mixed crystals are studied in the framework of the continuum model of Born and Huang and the random-element-isodisplacement model. A normal-coordinate system to describe the optical vibration in ternary mixed crystals is correctly a…
Structural materials in fusion reactors will operate in harsh radiation conditions including high displacement rates from 14 MeV neutrons with accompanying high levels of hydrogen and helium production and will experience severe property degradation. Predicting their in-service performance requires a detailed understa…
Using a binder-less PcBN tool, improvement of processing efficiency was tried in machining of a vanadium-free titanium alloy, Ti-6Al-2Nb-1Ta which was recently applied for a surgical implant material. The tool which is prepared through the direct conversion sintering of h-BN under both high pressure and temperature, e…
The mechanical properties of free standing films of as prepared and acid purified single-walled carbon nanotubes were studied by means of tensile stress measurements as well as electron microscopy. Films appear to fail by crack propagation involving rupture or matrix pull-out of bridging nanotube bundles.
Lu2Pc2 and lithium hexylthio-phthalocyanine have been used to synthesize [Lu2(Pc)4] which exhibits variable range hopping conductivity as inorganic semiconductors and also observed electrochromic effect from cyclic voltammetric (CV) measurement.
We first provide an overview of some predominant theoretical methods currently used for predicting thermal conductivity of thin dielectric films: the equation of radiative transfer, the temperature‐dependent thermal conductivity theories based on the Callaway model, and the molecular dynamics simulation. This overview…
Plastic formability in the secondary processing of an AZ31 magnesium alloy was investigated using fine-grained and relatively coarse-grained materials, respectively. To produce components for mobile electric appliances, boss formability was examined at a relatively low temperature of 523 K. The boss with a height of 1…
The adsorption properties of water adsorbed on various silica substrates are investigated by way of Grand Canonical Monte Carlo simulations (GCMC). The SPC and PN-TrAZ potential are used to describe water–water and water–silica interactions. The numerical sample of mesoporous silica glass (pore size: 3.6 nm) was obtai…
A new bis(indenyl)zirconocene bearing a pendant Si-Cl anchor has been grafted onto MCM-41, SBA-15, MCM-48 and a disordered mesoporous silica for the polymerisation of ethylene and propylene, producing polymers with very high molecular weights, low polydispersities and, in the case of polypropylene, higher levels of is…
The effect of partial substitution of Mn for Ni on the structural and electrochemical properties of the hydrogen storage alloys has been investigated systematically. The results of X-ray powder diffraction and Rietveld analyses showed that all alloys consisted of the phase and the phase, and the content of the phase f…
Fabric utility parameters most often depend on its mechanical properties. The most important strength parameters include unidirectional tensile strength, tear strength and elasticity properties. In this work we describe in detail the problem of tear strength, appropriate measurement methods and the correlation relatio…
Description Fifty-nine peer-reviewed papers provide the latest international research on nuclear materials. Although the primary focus is on pressure vessel steels, including mechanical properties and microstructures, it contains papers on the latest research on fundamentals of radiation effects in materials as well a…
二酸化炭素排出の抑制につながるとして期待されている植物由来の高分子であるポリ (L-乳酸) (PLLA) に対して, 新たな循環方法を提案するために, そのモノマー化技術について検討を行った. 優れた加水分解能力を有することが明らかである水熱反応を用いてPLLAを加水分解し, モノマーであるL-乳酸を回収することを目的として, モノマー化に与える影響因子について検討した. その結果, 光学純度が低下することなしに, L-乳酸が高収率で得られる条件は, 反応温度220～230℃, 反応時間20分であることが明らかとなった. このことから, 触媒などの添加剤を要することなく水のみにより, PLLAから容易に高い収率でモノマーが得られる…
Thorough examination of a previous report on the high solubility of carbon nanotubes in refluxing aniline reveals that the reported optical properties of the “nanotube” solution are due to aniline decomposition products, rather than functionalized nanotubes. No appreciable dissolution of single-wall carbon nanotubes c…
The behavior of leakage current and electric field of insulators primarily depends on the environmental stresses. A mathematical analysis based on dimensional analysis technique is applied to develop the correlation of leakage current (LC) and electric field with the physical variables of the environmental stresses. T…
5,15-Bis[acetylene-4-(ethylenedioxy)thiophene]-10,20-bis(4-carboxyphenyl)porphyrin was synthesized by a Sonogashira coupling and polymerized to fibres; TEM and AFM images show uniform porphyrin wires with a length of several micrometers and a thickness of less than 4 nm.
The use of organogelators to template chiral and achiral polyaniline superstructures via the electrostatic interaction between anionic sulfonated polyaniline and a cationic gelator is described.
