Abstract The thermal decomposition of organophosphorus fire‐retardant (OP1311) and/ or organonanoclay (Cloisite 30B) is hereby investigated employing thermogravimetric analysis (TGA), to give an insight into their intrinsic behaviour and interaction in polymer nanocomposites for fire safety applications, because the a…
At JAEA, a test blanket module (TBM) with a water-cooled solid breeder is being developed. This paper presents recent achievements of research activities for the TBM, particularly addressing the pebble bed of the tritium breeder materials and tritium behaviour. For the breeder material, the chemical stability of Li 2…
A systematic investigation into the assembly and stability of native and modified subunits of the Shiga toxins (Stx) in vitro is described. Analysis of the assembly of native and modified B subunits of Stx1 and Stx2 in solution, carried out using electrospray ionization mass spectrometry (ES-MS), suggests that the low…
The thermoelectric properties of double-filled skutterudites Ca0.1CexCo4Sb12 (x = 0.05, 0.10 and 0.15) were investigated at temperatures ranging from 300 to 775 K. The results showed that the addition of Ca and Ce as filler atoms into CoSb3 led to a substantial decrease in lattice thermal conductivity. The minimum lat…
Abstract In this work, a thermoplastic shape memory polyurethane was prepared via melt polymerization and a corresponding shape memory hollow fiber was fabricated via melt spinning. The fiber mechanical properties, especially shape memory effect, were characterized by static tensile, thermo‐mechanical cyclic tensile t…
A structural and magnetic characterization of a trinuclear chiral Mn(II) formate three-dimensional framework exhibiting a triangular arrangement is presented. Compound Na(3)[Mn(3)(HCOO)(9)] was obtained by solvothermal synthesis and crystallizes in the chiral cubic space group P2(1)3 and is well described by a Delta c…
Novel hydrogen-bonded supramolecular thioarsenates [Fe(phen)(3)][As(3)S(6)] x dien x 7 H(2)O (1) and [Mn(2)(phen)(4)(As(2)S(5))] x phen x 2 H(2)O (2) (dien = diethylenetriamine, phen = 1,10-phenanthroline) were hydrothermally synthesized and characterized. The structure of 1 consists of [As(3)S(6)](3-)-H(2)O anionic l…
We report on the magnetic field $(H)$, hydrostatic pressure $(P)$, and doping dependence of the order of the ferromagnetic (FM) to paramagnetic (PM) phase transition in ${\text{Sm}}_{0.52}{\text{Sr}}_{0.48}{\text{MnO}}_{3}$ single crystal. It has been shown that $({H}_{\text{cr}}\ensuremath{\approx}4\text{ }\text{T},\…
Near infrared (NIR) techniques for the measurement of cotton-polyester (PET) blend content have concentrated on yarn slivers and greige fabrics rather than the more difficult application to dyed or printed fabrics. The need for a robust and rapid measurement of the fiber content in dyed cotton-PET fabrics has been exp…
Abstract Dielectric spectroscopy (10 −2 Hz to 10 6 Hz) was employed to investigate the molecular dynamics of hyperbranched polyesters where the number of the generation is systematically varied from 2 to 5. As a first result, the dielectric properties depends strongly on the generation of the hyperbranched polymers. F…
meso-Octakis(pentafluorophenyl)-substituted [36]octaphyrin(1.1.1.1.1.1.1.1) (1) is a figure-of-eight nonaromatic macrocycle that serves as a unique platform to induce a metathesis-like splitting reaction upon bis-Cu(II) metalation. To get a better understanding of this splitting reaction, we examined the metalation of…
A novel plasma-enhanced atomic layer deposition-grown mixed-phase/nanolaminate Ru–TaN barrier has been investigated, and it was confirmed that the copper diffusion barrier and direct-plate characteristics of the mixed-phase barrier can be modulated by varying the metal ratio in the film. This liner was subsequently op…
Using Brownian dynamics computer simulations we show that binary mixtures of colloids driven in opposite directions by an oscillating external field exhibit axial segregation in sheets perpendicular to the drive direction. The segregation effect is stable only in a finite window of oscillation frequencies and driving…
The orbital magnetism in spatially varying magnetic fields is studied in monolayer graphene within the effective-mass approximation. We find that, unlike the conventional two-dimensional electron system, graphene with a small Fermi wave number kF works as a magnetic shield where the field produced by a magnetic object…
Polycrystalline Fe3(1−δ)O4 films were fabricated using a dc reactive sputtering system, and the relative Fe3+/Fe2+ ratio in the films was adjusted slightly by changing the O2 flow rate (OFR). The lattice structure of all the films is inverse spinel, but the Fe3+/Fe2+ ratio increases with the increasing OFR. The Verwey…
The initiation sensitivity is highly dependent on void structures within an energetic material. It is technically feasible to modify the initiation sensitivity by lithographically defining the size and distribution of included voids on the micro- and nanoscale. We proposed a method to pattern organic energetic materia…
Elliptic cylindrical cloaks are investigated analytically in elliptic cylindrical coordinates. It is shown that both the linear and higher-order transformations produce an imperfect cloaking due to the poor symmetry of the coordinate system. The imperfection being in concordance with that obtained by numerical simulat…
A rate equation approach is used to model an experimentally realized ~ 2 mum Tm3+-doped tellurite fiber laser utilizing an in-band pumping scheme (3H6rarr3F4) . Excellent agreement between the theoretically predicted and experimentally measured slope efficiency is obtained. It is shown that in order to achieve agreeme…
An indirect electronic transition from the L point valence band to the T point valence band has been previously observed in Bi nanowires oriented along the $[01\overline{1}2]$ crystalline direction (used by Black et al. and by Reppert et al.) but not in $[11\overline{2}0]$-oriented nanowires (used by Cornelius et al.)…
Abstract On the basis of the fusion behavior of poly(vinyl chloride) (PVC), the influence of compounding route on the properties of PVC/(layered silicate) nanocomposites was studied. Four different compounding addition sequences were examined during the melt compounding of PVC with montmorillonite (MMT) clay, includin…
