Description Features the most current test and analysis methods applied to composite materials and structures, as well as this decade's latest technological developments in composites. 21 papers from the world's leading experts in the field focus on the following categories: • Environmental Effects Testing, •Design Al…
The crystallization rates of fused nifedipine in 6 mixtures with different polymeric pharmaceutical excipients were each measured as a function of the water content using an isothermal microcalorimeter. In all the excipients studied, the crystallization rate increased as the water content increased, but the extent of…
Silver decoration method was applied to platinum, palladium and type 304 austenitic stainless steel to visualize the hydrogen distribution in those metals. The electrochemically hydrogen-charged specimens were dipped into the silver decoration solution of K[Ag(CN)2]. The silver decoration process was confirmed to be c…
Some azines with potential nonlinear optical properties of the second order have been synthesised by condensation of the appropriate hydrazones and aldehydes. The compounds have been chemically functionalised to allow their use in the synthesis of polymers containing the azine groups as side chain pendants. The charac…
Hectorite type clays modified with gadolinium(III) were prepared by ion-exchange of natural (SHCa) hectorite and synthetic (SLH) hectorite. Results show that Gd(III) content in the clay increases with increasing gadolinium(III) in the exchange solution within the range between 0 and 25% of the Gd/clay weight ratio. St…
Palladium membrane has been studied for sepration and purification of hydrogen isotopes because of its large permeability. In order to consider permeation of mixture of hydrogen isotopes, solubilities of protium and deuterium in palladium were studied in the temperature range of room temperature to 500°C using breakth…
Transmission electron microscopy (TEM) specimens of a first core heat of 316 stainless steel, in both the solution annealed and 20% cold worked condition, were irradiated to 46 dpa at 420°C, to 49 dpa at 520°C, and to 34 dpa at 600°C in FFTF/MOTA. Prior to irradiation, some of the specimens were pre-implanted with app…
Fouling plays a dominant role in heat exchanger performance. It is extremely important to choose the most appropriate type of heat exchanger for a particular application and adopt proper values for fouling resistance. A design practice for shell-and-tube heat exchangers that will limit fouling to a minimum and thus en…
This review describes current trend in development of corrosion protective plating for applications in the automotive, buildings, aircraft and others industries. Although zinc is widely used for providing sacrificial (cathode) protection to steel in a severe corrosion environment, zinc is consumed rapidly. Recent dema…
Sialate lyase (sialate aldolase; systematic name N-acetylneuraminate pyruvate-lyase, EC 4.1.3.3) was isolated as soluble enzyme from pig kidney and purified 630-fold using a heating step, gel filtration, and chromatography on immobilized neuraminic acid beta-methyl glycoside in 14% yield to apparent homogeneity as tes…
To calculate the radial current distribution and core loss within a concentric-lay steel-cored conductor, the magnetic properties of the core must be known for any service condition. The paper describes comprehensive measurements on a length of the steel core taken from a 54/3.77 mm+19/2.24 mn (Grackle) ACSR conductor…
The introduction of Zr-lined “barrier” fuel clad tubing by GE in the early 1980s to counter the pellet-clad interaction (PCI) failure mechanism in fuel for boiling water reactors provided a major improvement in fuel reliability and operational flexibility. While the frequency of fuel failures has been substantially re…
Abstract The temperature dependences of the electrical resistivity and Hall mobility of p ‐type InTe chain single crystals in parallel and perpendicular directions to c ‐axis have been investigated in the temperature range of 28–260 K. The high anisotropy between ∂‖ and ∂⟂ which depends on temperature is attributed to…
An inhomogeneous lattice self-consistent field (SCF) theory is applied to wetting problems. In this method molecular details, such as chain length, chain architecture, and short-range molecular interaction parameters are the input parameters. In a 1D (one-dimensional) SCF calculation adsorption isotherms, interfacial…
We find the response of a grafted polymer brush in a melt state to the insertion of a small, impenetrable object in its bulk. The response is calculated by means of perturbation theory applied to Semenov's self-consistent mean-field theory of polymer brushes. We find that both the induced pressure field and the deform…
The reaction of hexachlorocyclotriphosphazene, N3P3Cl6 with pyridine-2-thiol affords only a geminal isomer, 1,1-bis(pyridyl-2-thio)-3,3,5,5-tetrachlorocyclotriphosphazene. Crystallographic characterization discloses that the nitrogen atom of the pyridine-2-thiolate group significantly interacts with the phosphorus ato…
The synthesis of the first liquid-crystalline allene derivatives with chiral smectic C-phases is reported.
The coadsorption of NO and NH 3 on Cu(111) was investigated by means of LEED, HREELS, and TPD. A new ordered (2 × 2) structure was found after annealing to 180 K NO−NH 3 coadlayers prepared from various relative exposures of NO and NH 3 at 100 K. A N 2 O desorption peak from the coadlayer appeared at 220 K, which was…
Electrical conduction paths through the Ni phase in Ni/yttria-stabilized zirconia (YSZ) cermet heve been analyzed using a Monte Carlo simulation based on percolation theory and electrical conductivity measurement. The minimum Ni-volume fraction of total solids determined from the electrical conductivity measurement is…
The complexes of iron(III) tetra(2-N-methylpyridyl)porphyrin with vinyl acetic acid and a selection of α-halo and α-hydroxycarboxylic acids, α-,β- and γ-ketoacids, β-dicarboxylic acids and polyacrylic acid have been photolysed (λ > 390 nm) in anaerobic aqueous solution. UV–VIS spectroscopy shows that the primary react…
