By combining X-ray diffraction and X-ray absorption spectroscopy, the structural evolution of the InSe alloy has been explored up to 3.3 GPa and 1500 K with the use of the Paris–Edinburgh large volume cell. These conditions allowed us to study the solid and the liquid states and to measure the pressure evolution of th…
A model experiment was performed to investigate movement of inclusions near the solid wall and engulfment into the solidifying front. Polystyrene particles (100 μm in diameter) were suspended in flowing melts (water, 20 mass% NaCl aqueous solution and succinonitrile). As the average flow velocity increased, number of…
A general purpose shape memory alloy model has been developed and implemented in MSC.Marc 2003. This model is based on a phenomenological model that provides a description of a wide range of the observed behavior, which is tractable from both analytical and computational viewpoint. The present model describes the deve…
X‐ray photoelectron spectra (XPS) of carbyne‐like carbon (CLC) film obtained by the polymer reaction route were measured and analysed. Dehydrohalogenation reaction was carried out effectively regardless of the starting precursors. Cls core‐level spectrum of CLC film shows the anomalous lowest peak maxima at 282.6 eV c…
This unique guide to Plone covers everything from installing Plone (on Mac OS X, Windows, and Linux) to writing code for the system. As part of the Apress library of Python programming and content man
Changes in composition of diatom (Bacillariophyceae) communities and pollen content were analyzed in two cores from the lake Krakower See, Mecklenburg-Vorpommern, Northern Germany. Based on the pollen stratigraphy, a time-depth-curve was built that allowed an estimate of the rate of sedimentation. The pollen curves, e…
One of the authors has proposed an HCCI combustion engine system that was fueled with dimethyl ether (DME) with a high cetane number and methanol-reformed gas (MRG) with a high anti-knock property in the previous research. In the system, both DME and MRG are to be produced from methanol by onboard-reformers utilizing…
Combustion tests on SiC/SiC CMC components were performed in an aircraft combustion environment using the rich-burn, quick-quench, lean-burn (RQL) sector rig. SiC/SiC fasteners were used to attach several of these components to the metallic rig structure. The effect of combustion exposure on the fastener material was…
The effect of impurities on formation of interfacial metallic voids, during uniform dissolution of aluminum in 1 M NaOH, was investigated. These voids are thought to act as initiation sites for pitting corrosion, and were previously shown to be formed by NaOH dissolution. Samples of three different bulk purities were…
Despite the significant amount of research on single-wall carbon nanotubes, their thermal conductivity has not been well established. To date only one experimental thermal conductivity measurement has been reported for these molecules around room temperature, with large uncertainty in the thermal conductivity values.…
The conformational equilibrium of methyl 2-fluoropropionate (1) was studied through a combination of NMR, theoretical calculations and solvation theory. IR spectroscopy was used as an auxiliary technique for this analysis. The 1JCF couplings were analysed using theoretical and solvation calculations to give conformer…
A synthetic approach to polyurethane cationomers containing S-pyroglutamyl-S-glutamic acid dipeptide (S-PyGlu-S-Glu) and alkylammonium groups is presented. Two segmented polycations, based on polycaprolactone diol, isophorone diisocyanate and dipeptide together with N-methyldiethanolamine, subsequently quaternized wit…
The microscopic model based on the consideration of the proton ordering is proposed for theoretical study of glycine phosphite (GPI) crystals with a complex structure of the hydrogen bond network. The phase transition into the ferroelectric state is described and changes of the dielectric susceptibility of the crystal…
The Split Hopkinson pressure bar (SHPB) method has been used for impact tests such as compression and shearing, and is currently modified for tensile test, since the various kinds of high strength sheet metals are greatly concerned with the safety and the energy saving demands for high velocity vehicles. Evaluation of…
Aircraft jet engine should be designed to keep the required performance against for the event of foreign object ingestion, such as bird-strike. For the purpose to realize highly efficient and more advanced design of fan blade of jet engine, a numerical simulation technique for bird-strike problem has developed. Good a…
Computer simulation of battery performance, especially from first principles, can provide valuable information for understanding how a battery performs under dynamic conditions. This paper describes recent progress made in incorporating both oxygen and hydrogen recombinant cycles in a computational fluid dynamics base…
Polymer-Dispersed Cholesteric Liquid Crystals(PDCLC)have been obtained using different cholesteric liquid crystals mixtures by the Photopolymerization-Induced Phase Separation method. PDCLC samples of different thickness and different LC concentrations have been studied. The selective reflection spectra for different…
Palladium nanoparticles encapsulated into graphite (Pd–graphite intercalation compound: Pd–GIC) were produced from two kinds of graphite, natural graphite (average flake size: 270 μm) and kish graphite (average flake size: 15 mm). Hydrogen storage properties of Pd–GIC have been investigated by means of differential sc…
In order to investigate the criterion for the persistent slip band (PSB) formation near a Σ3(111) coherent twin boundary, where is a preferential site for formation of PSB, a high-cycle fatigue test is carried out at room temperature using a copper bicrystal specimen with the twin boundary. PSBs are observed near the…
Annihilation processes of radiation defects induced in solid-tritium breeding materials by neutron irradiation were studied by ESR measurement. The ESR spectrum for neutron-irradiated Li 2 TiO 3 is asymmetric, hence it is consists of several signals. This means that there are some para-magnetic radiation defects. The…
