Neutron resonance densitometry (NRD) is a non-destructive analysis method, which can be applied to quantify special nuclear materials (SNM) in small particle-like debris of melted fuel that are formed in severe accidents of nuclear reactors such as the Fukushima Daiichi nuclear power plants. NRD uses neutron resonance…
How to apply a reduced model for the turbulent ion heat diffusivity [Nunami M et al. 2013 Phys. Plasmas, 20 092307] derived from a gyrokinetic code to a transport simulation is proposed. The reduced model is given by the function of the linear growth rate of the ion temperature gradient (ITG) mode and the decay time o…
Abstract Whether or not electron–electron pairing by the nominally repulsive Coulomb interaction, can give rise to superconductivity by itself is reviewed. The generic scenario of the pairing by electron–electron interaction put forward by Kohn and Luttinger is considered, as are modern studies of the electronic mecha…
Surface-reactive luminescent vesicles were prepared by self-assembly of phospholipids, amphiphilic maleimides and fluorophors in aqueous solution. Those preformed liposomes were functionalized with various thiolated receptor units using a thiol-click reaction. As recognition elements, a bis-Zn(2+)-cyclen derivative fo…
In this article, we demonstrate plasmonic-induced optical transparency (PIT) in a planar metamaterial consisting of a metallic regular triangle (RT) embedded in a ring nanostructure. The interference between the bright dipole mode of the RT and the dark quadrupole mode of the ring leads to the emergence of a transpare…
Ultradense macroscopic arrays of ferromagnetic alloy nanowires exhibit unique properties that make them attractive both for basic physics studies and for prospective nanodevice applications in various areas. We report here on the production of self-organized equiatomic FePt nanowires produced by glancing-angle ion-bea…
Abstract Lattice protein models are well-studied abstractions of globular proteins. By discretizing the structure space and simplifying the energy model over regular proteins, they enable detailed studies of protein structure formation and evolution. However, even in the simplest lattice protein models, the prediction…
An electrorheological (ER) model (Seo‐Seo model) was applied to the yield stress analysis of the electrorheological fluids containing core–shell structured, snowman‐like anisotropic poly(methyl methacrylate) micro particles. The model predictions were compared with the experimental data, to reveal a good agreement wit…
Visible light-active TiO 2 (B)/anatase heterojunction nanotubes are prepared, which show better visible light photocatalytic activity than commercial Degussa P25.
This paper reports on a biofuel cell with a dimension of 13 × 24 mm 2 fabricated on a flexible polyimide substrate. I its porous carbon-coated platinum (Pt) electrodes of 3 mm in width and 10 mm in length were fabricated using photolithography and screen printing techniques. Porous carbon was deposited by screen print…
We report on the usage of Carbon Nanowalls (CNW) synthesized by a PECVD process as electrode material for oxygen reduction reaction (ORR). In order to substitute the platinum based catalysts in fuel cells, graphene is a promising candidate. Carbon Nanowalls are a graphene modification with good accessibility and a con…
The morpho‐structural and electrochemical properties of the oxide film formed on the implants surface play a decisive role for the bio‐compatibility of titanium‐based prosthesis. The aim of the present work is to investigate and compare the corrosion behavior of titanium dioxide (TiO2) coated Ti–6Al–7Nb prepared by an…
We present a-Si:H/µc-Si:H tandem solar cells on laser textured ZnO:Al front contact layers. Direct pulsed laser interference patterning (DLIP) was used for writing arrays of one-dimensional micro gratings of submicron period into ZnO:Al films. The laser texture provides good light trapping which is indicated by an inc…
Sulfonated carbons were explored as functionalized supports for Ni nanoparticles to hydrodeoxygenate (HDO) phenol. Both hexadecane and water were used as solvents. The dual-functional Ni catalysts supported on sulfonated carbon (Ni/C-SO3H) showed high rates for phenol hydrodeoxygenation in liquid hexadecane, but not i…
We report a controllable one-step calcination synthesis of NaV 3 O 8 nanobelts, nanorods and microrods. In situ TEM characterization confirms the basic lithiation mechanism of NaV 3 O 8 cathode materials.
Highly ordered Fe2O3 nanotube arrays have been fabricated by a simple and cost effective anodisation method on iron foils in an ethylene glycol solution containing NH4F and H2O. The Fe2O3 nanotube electrodes were characterised by field emission SEM, energy dispersive X-ray spectroscopy and UV–vis absorbance spectra. T…
The effect of bamboo portions and beating revolution on paper made from Gigantochloa scortechinii was determined. The bamboo was pulped using soda- anthraquinone (AQ) pulping comparing two pulping conditions (alkali 15 & 20%, temperature 160 & 170°C) for different bamboo portions consisted of top, middle and bottom. H…
Abstract Poly(methyl methacrylate) was mixed with poly[(vinylidene chloride)‐co‐acrylonitrile] (Saran‐F) and lithium perchlorate in tetrahydrofuran to make polymer blend systems. Solvent‐free membranes with various blend ratios were prepared using a solution casting technique. Impedance analysis was used to study the…
Low-emitting cotton fabric with low infrared emissivity near to 0.795 at the wavebands of 8–14 µm was prepared using mesoporous carbon-aluminum doped zinc oxide (C-AZO) coatings. The effects of binders, the content of C-AZO composites, coating thickness and roughness of fabrics on the infrared emissivity were investig…
We present theoretical scaling and computational analysis of nanostructured free surfaces formed in chiral liquid crystals (LC) and plant-based twisted plywoods. A nemato-capillary model is used to derive a generalized equation that governs the shape of cholesteric free surfaces. It is shown that the shape equation in…
