Nanostripes with very high (>20) aspect ratios of a two-dimensional manganese oxide phase are grown on the Ag(100) surface using a physical vapor deposition method and thoroughly characterized via low-energy electron diffraction and scanning tunneling microscopy. Despite the square pattern of the substrate, symmetr…
Abstract This paper investigates the size effects of the gas diffusion layer underneath the channel rib on the performance of a planar solid oxide fuel cell (SOFC). Based on 3‐dimensional numerical simulations, the sensitivities of the electrical performance parameters (Nernst potential and current density) and the th…
Crystals of the silver(I) thioaurate(I), AgAuS, were obtained by fusing the elements in stoichiometric amounts. The X-ray diffraction analysis showed that the synthesized phase AgAuS represents a new structural type. The unit cell parameters are a = 13.4235(3), c = 9.0873(4) Å, V = 1418.07(6) Å3 and Z = 24, and the sp…
Informatics based approaches are employed to find a suitable composition of Ti alloy, with high strength, low elastic modulus, adequate biocompatibility and low cost. Artificial neural network, capable of prediction and diagnosis in non-linear and complex systems, is used to obtain the relationship of composition and…
We study the interaction of a liquid drop with an elastic beam in the case where bending effects dominate. We use a variational approach to derive equilibrium equations for the system in the presence of gravity and in the presence or absence of contact line pinning. We show that the derived equilibrium equations for t…
Small-angle scattering in grazing-incidence beam geometry has been applied on a time-of-flight neutron instrument to investigate a solid–liquid boundary. Owing to the broad wavelength distribution provided for a specific incident beam angle, the penetration depth of the neutron beam is varied over a wide range in a si…
We hypothesize that citreoviridin (CIT) induces DNA damage in human liver-derived HepG2 cells through an oxidative stress mechanism and that N-acetyl-l-cysteine (NAC) protects against CIT-induced DNA damage in HepG2 cells. CIT-induced DNA damage in HepG2 cells was evaluated by alkaline single-cell gel electrophoresis…
We report a novel approach of designing ordered arrangement of disorder on the extended structures of graphene. We prepared single phase nanoparticles of Co 80 Ni 20 alloy embedded in Reduced Graphene Oxide (RGO). Co 80 Ni 20 shows a large moment and a soft ferromagnetic character like permalloy at room temperature. T…
In this paper, the tensile properties of plain-woven aramid fabric style 724 (Kevlar ® 129 fibre, 1000 denier, 24×24 yarns per inch) and the tensile properties of individual aramid yarn extracted from the fabric are presented. It was found that this fabric is balanced with less than 5% difference in strength between t…
Abstract The metal‐supported intermediate temperature solid oxide fuel cells with a porous nickel substrate, a nano‐structured LDC (Ce 0.55 La 0.45 O 2–δ )–Ni composite anode, an LDC diffusion barrier layer, an LSGM (La 0.8 Sr 0.2 Ga 0.8 Mg 0.2 O 3–δ ) electrolyte, an LSCF (La 0.58 Sr 0.4 Co 0.2 Fe 0.8 O 3–δ )–LSGM co…
A quinoxaline-fused tetrathiafulvalene (TTF) derivative <bold>1</bold> has been synthesized to form a compact and planar π-conjugated donor–acceptor (D–π–A) ensemble, and its single crystal structure has been determined by X-ray diffraction.
Electronic band structure calculations were performed on the nonmagnetc (NM) and antiferromagnetic (AFM) phases of LiFe X (X = P , As and Sb ) compounds using ab initio method. The crystal structure of these compounds is well tetragonal P4/nmm structure (space group = 129). Self-consistent calculations were performed…
Fluorine-doped tin oxide (FTO) films were prepared by pulsed DC magnetron sputtering with a metal Sn target. Two different modes were applied to deposit the FTO films, and their respective optical and electrical properties were evaluated. In the transition mode, the minimum resistivity of the FTO film was 1.63×10(-3)…
Microstructures and mechanical properties of the Mg–5Gd–2Y–2Zn–0·5Zr alloy (wt-%) in the as cast and solution treated conditions have been investigated using optical microscopy, scanning electron microscope, X-ray diffraction, electron probe X-ray microanalyser and transmission electron microscope. The results show th…
In this study, numerous types of straight hetero-junction carbon nanotubes (CNTs) and their fundamental CNTs were investigated by the finite element method (FEM). By applying the FEM, the shear behavior of these hetero-junctions was obtained thorough numerical simulation. The behavior of hetero-junctions and their con…
The formation of an adiabatic shear band (ASB) experiences three stages: stable plastic flow, nucleation and a fluid-like stage. For different stages, the microstructures of the material undergo great changes. The mechanical behavior of the material in each stage has its own unique characteristics. To describe these c…
On the basis of a statistical analysis of the data deposited in the Protein Data Bank [Berman et al. (2000). Nucleic Acids Res. 28 , 235–242; Bernstein et al. (1977). J. Mol. Biol. 112 , 535–542], it is shown that two symmetry-related protein molecules are frequently bridged by a small molecule/monoatomic ion, which w…
We report ripening of metal particles anchored on pyramid-shaped heterostructure nanocrystals. The 'intra-particle' ripening results in a large metal tip at one corner with the other three tips vanishing. Investigation reveals that the ripening and core/shell formation affects photocatalytic activities via the Fermi l…
Vaterite composite particles with a size-controlled sphere were obtained by a carbonate controlled-addition method by using a carboxylate-terminated poly(amidoamine) (PAMAM)-type polyhedral oligomeric silsesquioxane (POSS)-core dendrimer. An aqueous ammonium carbonate solution was added to an aqueous solution of the d…
