number: 262 ABSTRACT In the Japan Power Demonstration Reactor decommissioning program remote handling technologies were developed that could be successfully applied to dismantling the core components and verified by successful work accomplishment. However, wider applications and intelligence to the work process were r…
We have measured contact angles for a range of pure oils of different cohesive energy density and surfactant solutions in oil on polyethylene (PE) and polytetrafluoroethylene (PTFE) solid surfaces. For the pure oils, the measured contact angles are in approximate agreement with values calculated using dispersion force…
The extended cantilever model (ECM) for transformer or inductor windings is convenient from the parameter extraction standpoint since, theoretically, each model parameter can be extracted from a single measurement of an open-circuit voltage or a short-circuit current. The impedance of the sensor used to measure a shor…
In this work, pressure-thickness relation is investigated for a series of plain and rib knitted structures made from cashmere and polyester textured (PET) yarns. The pressure-thickness curve during lateral compression is divided into three regions, namely, the first linear region followed by the non-linear region and…
Zero NOx emissions are obtained in the catalytic combustion of simulated biomass mixtures containing substantial amounts of ammonia by optimisation of NH3 oxidation and NOx reduction using a 2%Rh–Al2O3 catalyst.
A series of acid catalysts was prepared by heating of NH 4 -saturated montmorillonite at 200-600 °C for 24 h. Their catalytic activity was tested in acetylation of 3,4,5-trimethoxybenzaldehyde with acetic anhydride. This reaction is sufficiently sensitive to modification of the catalyst and thus suitable for testing c…
We analyze dielectric data obtained on PZT-5A samples which had been electrically deaged in a well defined way. Thus the exponent a of the power law characterizing the ac-field dependence of the effective dielectric coefficient ϵ11* could be determined with high accuracy. The result α′=1.10(1) and α″= 1.07(1) obtained…
Visible light irradiation of thin films of a main-chain liquid crystalline poly(aryl cinnamate) using ketocoumarins as triplet sensitizers leads to photochemical crosslinking and UV-vis and FTIR spectroscopic changes associated with saturation of the cinnamate double bond, most likely by 2 + 2 photocycloaddition. The…
Possibility of the ferroelastoelectric behavior manifestations in a uniaxial ferroelectric TGS crystal was investigated. Analysis of the spontaneous piezoelectric moduli tensors for each of the 180°-domains formed as a result of the phase transition in TGS revealed possible directions for simultaneous application of t…
Zeolite-modified chloranil (2,3,5,6-tetrachloro-p-benzoquinone) exhibits improved performance as a battery negative in comparison with an unmodified chloranil negative. A zinc–chloranil secondary battery incorporating the zeolite-modified negative yields 107 cycles in contrast to 50 cycles in the absence of the zeolit…
In this study, we synthesized 1,1,1-trimethlyolpropane (TMP)-based diol which has a pendant anionic group and a reactive double bond in the pendant cyclic ring. Then, a water-based urethane acrylate crosslinking agent (CA) was prepared from isophrone diisocyanate (IPDI), 2-hydroxyethyl acrylate (2-HEA), and a low mole…
We report the results of first-principles calculations on the electronic structure in ferromagnetic and non-magnetic hexagonal Mn V ( V = As, Sb, Bi). The calculations are based on the local-spin-density approximation (LSDA) of the density-functional theory (DFT) as well as the atomic sphere approximation (ASA) in the…

The stress corrosion cracking (SCC) susceptibility of several Fe-Ni-Cr-Mo alloys, which are candidate materials for high-level radioactive waste containers, was evaluated using slow strain rate and fracture mechanics testing. Slow strain rate tests of type 316L stainless steel (SS) and alloy 825 were performed in hot,…

The lowest-energy way to enclose and separate two planar regions of prescribed areas is found, where the energy is given by the l1 norm ('Manhattan metric'), in which horizontal and vertical directions use less energy than other directions, as in some crystals. With the assumption that interfaces carry a fraction lamb…
I give a brief introduction to Luttinger liquids. Luttinger liquids are paramagnetic one-dimensional metals without Landau quasi-particle excitations. The elementary excitations are collective charge and spin modes, leading to charge-spin separation. Correlation functions exhibit power-law behavior. All physical prope…
A new method is proposed to remove NO x and SO 2 simultaneously for flue gas cleanup. NO is first oxidized to NO x(x 1 5), and then is scrubbed together with SO 2 by aqueous ammonia and recovered as fertilizer. The key step is the selectively catalytic oxidation of NO in the gas phase. By using the quantitative analys…
OCTG (Oil Country Tubular Goods) and line pipes used for production and transportation of oil and gas are the major steel products which suffer hydrogen embrittlement (HE) because they are often exposed to wet hydrogen sulfide (sour) environments, where a lot of hydrogen enters the steel. Typical damage types of HE ar…
Amorphous graphite slurries used in flushing operations were conditioned at pH4.2 in the presence of chelatin and reducing agents both to release graphite and clayey particles and to enhance the hydrophobicity of the graphite surface. Graphite particles were first extracted from the aqueous slurry using a kerosene-bas…
