Electrochemical Reduction of NO x at Intermediate Temperatures Using a Proton-Conducting In3 + -Doped SnP2O7 Electrolyte, Nagao, Masahiro, Yoshii, Takeshi, Hibino, Takashi, Sano, Mitsuru, Tomita, Atsuko
The main focus of this paper is to highlight some of the key criteria in successful utilization of magnetostrictive materials within a cantilever based microelectromechanical system (MEMS). The behavior of coated cantilever beams is complex and many authors have offered solutions using analytical techniques. In this s…
A novel anode catalyst, C-MO-SDC ( carbon∕carbon black, , Ni, Co, ) was synthesized by employing a citrate∕nitrate combustion technique. Carbon materials, e.g., activated carbon and carbon black were first used to improve the solid oxide fuel cell (SOFC) anode properties, especially to improve the microstructure and t…
Electric-field measurements inside a negative-permeability-positive-permittivity metamaterial composed of arrays of split-ring resonators directly show that the theoretically predicted enhancement of evanescent waves in passive materials is physically realizable. To circumvent the extreme sensitivity of this phenomeno…

The phase behavior of some rodlike block molecules has been reviewed with reference to the polarity of constituent segments. It was found that the ability of the mesophase formation is connected with differences in polar character between the flexible chains and rigid cores. Thus the polar poly(oxyethylene) group conn…
We report on the electrical resistivity and magnetic susceptibility of La or Gd doped $R{\mathrm{CrSb}}_{3}$ ($R=\mathrm{La}$, Pr, Sm, and Gd). Single crystals were grown by increasing the nominal dopant by 25%. In general, two magnetic ordering transitions are found, ${T}_{c1}$ is attributed to ferromagnetic ordering…
A novel type of LaNi 1 – x Fe x O 3 ( x = 0.4 – 0.8 ) (LNF) perovskite oxide, specifically LaNi 0.4 Fe 0.6 O 3 (LNF-46), was synthesized and studied as the cathode for low-temperature, 400–500°C, solid oxide fuel cells (LTSOFCs). The maximum power density of 227 mW ∕ cm 2 was obtained at 450°C and a rather close resul…
Anode-supported solid oxide fuel cells (SOFCs) with a bilayered yttria-doped bismuth (YDB) and gadolinia-doped ceria (GDC) composite electrolyte film were developed. The cell with an YDB∕GDC composite electrolyte film showed an increase of in open-circuit voltage in the operating temperature range of , compared with t…
A polarization-independent liquid crystal (LC) lens is reported. There are four LC layers in the LC cell. Two LC layers focus one polarization component of an incident light wave, and the other two LC layers focus the other polarization components. The former two layers are placed interlacedly with the later two layer…
Abstract Structured latex particles with a slightly crosslinked poly(styrene‐ n ‐butyl acrylate) (PSB) core and a poly(styrene–methacrylate–vinyl triethoxide silane) (PSMV) shell were prepared by seed emulsion polymerization, and the latex particle structures were investigated with Fourier transform infrared, thermogr…
In glassy materials, aging proceeds at large times via thermal activation. We show that this can lead to negative dynamical response functions and novel and well-defined violations of the fluctuation-dissipation theorem, in particular, negative fluctuation-dissipation ratios. Our analysis is based on detailed theoreti…
Nanocable models comprised of BN nanotubes filled with close-packed Cu nanowires were investigated by gradient-corrected density functional theory (DFT) computations. The optimal distance between the sidewall of BN nanotubes and the atoms in a copper nanowire is about 0.35 nm, with a weak insertion energy (ca. -0.04 e…
In this study, a modelization of the viscoplastic behavior of amorphous polymers is proposed, from an approach originally developed for metal behavior at high temperature, in which state variable constitutive equations have been modified. A procedure for the identification of model parameters is developed through the…
Nanocomposite films containing Au nanoparticles embedded in a polymer matrix were prepared by vapour phase co-deposition of Au and polymers (Teflon AF and Poly(-methylstyrene)) in high vacuum. The microstructure of the composite materials as well as metal content strongly depend on the condensation coefficient of the…
We describe a general synthetic strategy for the preparation of a series of macrocyclic chiral manganese(III) salen complexes. The developed reaction pathway allows the modulation of the different key groups, namely, the chiral diimine, the bulky substituents in positions 3 and 3', and the linker used in the macrocycl…
A Au/Ni(111) surface alloy catalyzes the oxidation of CO at low temperature by at least three distinct mechanisms. At the lowest temperature of 70 K, molecularly adsorbed O2, spectroscopically characterized as peroxo or superoxo species bound at multiple sites with vibrational frequencies of 865 and 950 cm-1, is the r…
A synthetic water-soluble meso-tetra(2,6-dichloro-3-sulfonatophenyl)porphyrinate of iron(lll) chloride (FeP) was used as biomimetic catalyst in the oxidative coupling of three monomeric phenols (catechol, caffeic, and p-coumaric acids), which are common constituents of natural humic substances. The extent of oxidation…
In this paper we investigate the electronic structure and the thermopower for $\mathrm{Ni}({\mathrm{Ti}}_{0.5}{\mathrm{Hf}}_{0.5})\mathrm{Sn}$ and related half-Heusler compounds. Two different methods have been used to calculate the electronic structure, i.e., full potential linearized augmented plane wave method for…
Shape memory alloys (SMAs) have great potential for use in the field of civil engineering. The authors of this paper have been involved, from 1996, in several experimental and theoretical studies of the application of SMAs in civil engineering, for national and international research projects. This paper provides an o…
