The magnetization distribution in the L21 phase of a Ni2Mn(Al,Ga) alloy, which is a type of ferromagnetic shape memory alloy, has been studied by electron holography and Lorentz microscopy. This alloy contains many antiphase boundaries (APBs), which are introduced by the chemical ordering from the B2 state to the L21…
In our previous paper, mixed polyetheleneglycol (PEG) modification of liposomes by a mixture of 1-monomethoxypolyethyleneglycol-2,3-distearoylglycerol (PEG-DSG) with short polyoxyethylene chain and PEG-DSG with long one was shown to increase fixed aqueous layer thickness (FALT) around the liposomal membrane, and this…
Abstract In order to improve the processing and performance of tellurium (Te), bismuth (Bi), and bismuth telluride (dibismuth tritelluride, Bi2Te3), which are valuable thermoelectric materials that operate near room temperature in the bulk state, a nanometer scale synthetic method, in which the starting materials are…
The reorganisation of nanocrystals in order to reduce their surface energies has been examined in computer simulations. The relaxation takes a qualitatively different path for sphalerite- and wurtzite-structured particles. The surfaces of the sphalerite particles reconstruct into hexagonal nets, but the interior remai…
First paragraph: Platinum (as well as many other metals) may \nbe prepared in finely divided forms that are \nporous at all levels of magnification. Cracks and \ncrevices in the sponge-like opaque matrix then \nallow visible light (of wavelength around 0.5 μm) \nto enter, whereupon it undergoes mul…
Water contact angle has been measured to indirectly assess the sp2/sp3 ratio and hydrogen content of DLCH film under post N2 annealed treatment with O2 content under 100 ppm. XPS spectrum is used to measure the C1s bonding type and calculate the sp2/sp3 ratio. The surface morphology of DLCH film was examined by SEM an…
An overview of the intensification of industrial mixing will be presented. In many instances, it is not sufficient to increase a chemical reaction rate to achieve process intensification, as the rate of a reaction could be limited by mixing, heat transfer and mass transfer. An important strategy for process intensific…
The Ni(4) inverse metallacrown (NHEt(3)) [Ni(4)(bmo)4(Hael)2(ael)2](ClO(4))3 [(NHEt(3)).1.(ClO(4))3], with the inverse 12-MC-4 motif, has been assembled via simultaneous chelation and bridging of butan-2,3-dionemonoxime (Hbmo) and 2-amino ethanol (Hael).
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…
