We report a highly selective chemical interaction between single-walled carbon nanotubes and Triton X-100 according to nanotubes' electronic structure and diameter. The interaction is induced by laser irradiation at power densities down to 10-2 microW/microm2 but with photon energies matching those for electronic tran…
A viewing angle switching (VAS) panel used for the conversion of wide and narrow viewing angle has been demonstrated. Unlike the previous VAS panels, this one features a pair of same-handed circular polarizers and it is capable of switching the viewing angle omni-directionally from wide to narrow or vice versa by elec…
5% Co-doped cuprous oxide dilute magnetic semiconducting cluster film composed of two different sizes of crystalline nanoclusters, prepared using sputtering-aggregation technique is found to be ferromagnetic at 400K. With the increase in average crystallite size from 4.2to8nm, the coercivity increased. Magnetic field…
Electronic structure calculations (DFT) suggest that the series of hydrido-bridged binary coinage metal clusters with general formulae cyclo-CunAg3−n(μ2-H)n (n = 1–3), cyclo-CunAg4−n(μ2-H)n (n = 1–4) and cyclo-CunAg5−n(μ2-H)n (n = 1–5) are stable entities. The aromaticity of these bimetallic systems was explored by em…
We present a simple, generally applicable procedure for obtaining diameter-controlled SiO2@ carbon nanotubes (CNTs) coaxial nanocables. These coaxial nanocables with high solubility in polar solvents, have been used as functional templates for assembling CNTs/Au nanorods heterogeneous nanostructures to form multifunct…
This is not easy. Conch fishers suggest striking the shell between the third and fourth whorl on the turret with the sharp tip of another conch. If you don't have another conch, you are advised to use hammer, hatchet, or better yet a ma chete/7 according to one guide. What ever you do, it must be done expedi tiously,…
Purpose: The purpose of this paper is to determine the influence of welding on microstructure, mechanical properties, and stress corrosion cracking resistance of dissimilar stainless steels butt welded joints. Design/methodology/approach: Duplex 2205 and austenitic 316L steels were used. Butt joints of plates 15 mm in…

To understand basic electric properties of nano-sized magnesium oxide (MgO)/low-density polyethylene (LDPE) nanocomposite under DC voltage application, the volume resistivity, the space charge distribution, the breakdown strength and the short circuit tree were investigated. By the addition of nano-sized MgO filler, b…
The relationship between electrical conductivity and dielectric constant was investigated for 10 atom%Sm doped CeO2 (Ce0.9Sm0.1O2-δ), which is a typical oxide-ion conductor. Computer simulation clarified that anomalously large dielectric constant originated from the superimposition of both Debye-type dipole and interf…
By utilizing an alternating current (AC) magnetic system recently installed on our transmission electron microscope (TEM), in-situ Lorentz microscope observations of electrical steel sheets were carried out under an AC magnetic field. The domain walls moved smoothly under a low frequency AC magnetic field. By using di…
In this study, the effect of molding condition on the tensile properties for plain woven hemp fiber reinforced green composite was examined. The tensile properties of the composite were compared with those of the plain woven jute fiber composite fabricated by the same process. Emulsion type biodegradable resin or poly…
We have studied the electrochemistry of the organosulfur compound, 4-amino- -1,2,4-triazole-3,5-dithiol (ATAD), as a potential cathode electroactive material for lithium-ion rechargeable batteries. The redox behavior was investigated via cyclic voltammetry, and the charge-transfer kinetics of ATAD were compared to tho…
High aspect ratio Fe 0.55 Co 0.45 alloy nanowires were fabricated by electrochemical deposition from sulfamate solution into nanoporous templates with diameters between 20 and 200 nm and lengths up to 6 μ m . The capability to fill narrow (down to 20 nm in diameter) and deep (micrometer size) pores with high magnetic…
The mechanism of an acidic hydrolysis of cellulose is investigated by means of the PM3 molecular-orbital method. The investigation is performed on a sample consisting of 8 monomeric glucose units. The activation energies for the reactions of attacks of hydronium ions on glycosidic bonds in different positions are dete…
Novel fibronectin (FN)-based ultrathin films were prepared by layer-by-layer (LbL) assembly. Among the various combinations of extracellular matrix (ECM) proteins and glycosaminoglycans (GAGs) such as FN, gelatin (G), alpha-elastin (E) and heparin (Hep), FN/Hep, FN/G and FN/E nanofilms were successfully fabricated in…
Epoxy-coated AA2024-T3 samples were exposed to solutions of specific chloride concentration and pH. Underfilm corrosion processes were monitored in situ with confocal laser scanning microscopy. In near-neutral solutions, pitting at both intermetallic compounds and within the alloy matrix was observed during coating bl…
Layered ternary ceramics represent a new class of solids that combine the merits of both metals and ceramics. These unique properties are strongly related to their layered crystal structures and microstructures. The combination of atomic-resolution Z-contrast scanning transmission electron microscopy (STEM) and transm…
