High temperature fuel cells such as solid oxide fuel cells offer a high efficiency, fuel flexible, low emission strategy for distributed generation. In order to validate emissions performance of pollutants such as NOx and CO, analyzers that provide accurate measurements of low single digit values of these species are…
Article Crystal structure of trans-diaquabis(pyridine-2-carboxamide-N,O)-nickel(II)dibromide,[Ni(H2O)2{(OC(NH2)(C5H4N)}2]Br2 was published on April 1, 2005 in the journal Zeitschrift für Kristallographie - New Crystal Structures (volume 220, issue 1-4).
The array films of amorphous carbon nanorods were prepared by thermal catalytic pyrolysis of acetylene at 650°C on a porous anodic aluminum oxide (AAO) membrane with Co-Ni catalysts. The morphology and microstructure of the array films were examined by scanning electron microscopy (SEM) and Raman spectroscopy. The fri…
Reactive Ion Beam Etching (RIBE) of Pb(Zr,Ti)O3 thin film is performed for the via formation on a bilayer actuator. This actuator has been developed in the frame of health monitoring system for aircraft composite structures. The bilayer realization requires bore vias to connect the different conductive layers. It repr…
Alumina supported gold catalyst prepared by spray reaction method (spr) provides gold particles with about 20 nm diameter. The gold particle size is larger than for conventional gold catalysts. However, the spr catalyst shows catalytic activity for NO–CO reaction. In the present paper, we discuss the local structures…
Tungsten microcavity light sources and tungsten cluster light sources have interested us as light sources for next-generation having high luminous efficacy and long lifetime. The complex refractive index of tungsten requires the operating temperatures from 2000 K to 6500 K to evaluate the luminous efficacy and lifetim…
The oxidation and reduction characteristics of sputter-deposited Cu thin film with a preferred orientation have been studied. It was found that Cu oxide, which is identified as phase, is easily formed by annealing at 200°C in an ambient. The linear relation between thickness and the square root of oxidation time indic…
Se han identificado 33 taxones pertenecientes a 20 géneros de diatomeas marinas bentónicas y ticoplanctónicas asociadas al briozoo Zoobothryon verticillatum (Delle Chiaje). Para cada especie además de los datos taxonómicos, se aportan reseñas ecológicas y corológicas, referencias bibliográficas y fotografías originale…
Present knowledge on the formation mechanism of helium bubbles, which will enhance void swelling and lead to production of surface roughening and blistering as well as the high temperature intergranular embrittlement of metals during irradiation, is reviewed. Helium is strongly bound to a vacancy or a vacancy cluster…
Electrical stimulation on cell growth has been investigated extensively in vitro, especially on bone cells.This serves a good pre clinical study for treating injured bones since it has been demonstrated electrical stimulation, in spite of the mode, current or field, AC or DC, coupled or induced, continuous or pulsed,…
Electroactive polymers(EAPs) are one group of smart materials with unique electrical and mechanical properties.This paper will review developments of various kinds of EAPs home and abroad.EAP can be divided into two major categories based on their activation mechanism including ionic and electronic.The electronic EAP…
In this paper, the compatibility of dimethyl ether(DME) with other fuels, lubricity additives and polymers was studied by means of solubility parameter theory. The thermodynamic mechanism of the compatibility of DME with other fuels and materials was analysed. Meanwhile, two methods were introduced to effectively comp…
Transient and steady-state multi-wave mixing experiments are carried out on the novel azo＋c-tube liquid crystal sample. The shape of the diffracted multi-wave consists of rings under Ar＋（514.5nm） laser pump light, and th e nonlinear refractive index is n～0.8. Using different polarization states of the pump laser light…
Polylactide (PLA) polymers are among the most promising plastic made from renewable resources. Thermal stablization of these polymers remains a challenging issue of their industrial processing. We have studied the effect of TNPP in the scope of preventing the molecular weight reduction of PLA at its processing tempera…
We report the experimental structure determination of cold, mass selected Ag55 +/- cluster ions using the recently developed technique of trapped ion electron diffraction. By comparison of experimental and theoretical molecular scattering functions and consideration of computed total energies, we show that Ag 55 + con…
A novel solvent-based single wafer clean process with megasonic feature and single pass fresh solvent spray has been developed This process mitigated the copper undercut problem which existed in the conventional system. The electrical parametric performance meets or outperforms that from the baseline bench process. Mo…
In connection with the recent experimental discoveries on gigantic photoenhancements of the electronic conductivity and the quasi-static dielectric susceptibility in SrTiO 3 , we theoretically study a photo-generation mechanism of a charged ferroelectric domain in this quantum dielectric. The photo-generated electron,…
The homogeneity of typical electrolessly plated Pd/Ag membranes for H2 separation was investigated with XAFS and XPS depth profiling. Next the crucial mixing of the separate Pd and Ag layers, obtained after the two sequential plating steps, was followed in situ with XRD. The results show that some low temperature allo…
Transport models for carrier transport in a semiconducting carbon nanotube are presented. Results encompass tubes of varying diameter and chirality. The focus is on transport in response to a small, axially applied electric field. Models for phonon-limited transport are developed whereby carriers scatter with stretchi…
