The evolution of BWR fuel assemblies over the last forty years was driven by improvement of plant economics in combination with a substantial increase of fuel assembly burnup from 30 MWd/kgU up to 70 MWd/kgU. Additional thermal margins obtained by transition from 7x7 to 10x10 lattices were consumed in more efficient c…
Article Crystal structure of diaquabis(2-fluorobenzoato-kO)bis(1,10- phenanthroline-k2N,N′)barium(II), Ba(H2O)2(C7H4FO2)2(C12H8N2)2 was published on March 1, 2010 in the journal Zeitschrift für Kristallographie - New Crystal Structures (volume 225, issue 1).
Heterogeneous nucleation is a critical factor for grain refinement magnesium alloys. The paper reports the Al-9wt.%Mg-10wt.%SiCp master alloy were prepared by adding SiCp into the Al-Mg molten with stirring in 610-595°C, which were introduced into AZ91. Experimental results indicated Al4C3 were in situ synthesis on th…
Mg2Si/AM60 composites were fabricated by in-situ synthesis and the effects of different stirring technological parameters on the microstructures of semi-solid magnesium matrix composites were investigated in this paper. The results indicated that there were Chinese script type Mg2Si particles in the microstructures by…

An overview is provided of a new rail steel development program initiated with the aim of developing next generation rail steels with superior service performance and reduced life cycle costs. Two years into the program, the technology has reached a maturation point and one of the rail steels will now be advanced to r…
Abstract This thesis describes the design, fabrication and operation of a microfluidic device for the screening of biomolecule mixture surface mediated effects. The characterisation of a surface immobilisation strategy that will allow the robust attachment of candidate biomolecules on a substrate for use in cell cultu…
The thermal treatment for carbon nanotube was applied to remove the water, metal catalyst and other impurities in carbon nanotube. The surface of carbon nanotube was changed into open structure with acid treatment by mixed solution of HNO₃ and H₂SO₄. The dispersion property of the functionalized and modified carbon na…

Characteristic of hydrogen production was investigated to find the optimum heat pretreatment conditions for the anaerobic fermentation of food waste. The heat pretreatment of food waste enhanced the hydrogen yield due to the increase of soluble chemical oxygen demand (SCOD) and carbohydrate content. This result reveal…
We developed green chemical synthesis of alkyl lactates from triose by using Aluminium-exchanged montmorillonite (Al3+-mont) as a solid acid catalyst. The Al3+-mont catalyzed triose transformation efficiently to afford high yield and selectivity of alkyl lactates. Moreover, this catalyst was applicable for large-scale…
The HANARO nuclear research reactor had been operated successfully and smoothly up to the year 2008 since its first year of instability in year 1995 just after the completion of construction. But the reliability of the reactor has been degraded from the year 2009 due to new experimental facilities such as Feul Test Lo…
ENGLISH ABSTRACT: Impact polypropylene copolymers (IPPC) are important commercial materials, but their morphology and molecular architecture are not yet fully understood. In this study the focus was on selectively removing specific fractions from the original IPPC, recombining the remaining fractions, and studying the…

An experiment was conducted to investigate the effect of dietary supplementation of rare earth, individually and in combination with colloidal silver on growth performance, nutrient digestibility, carcass characteristics and immune response in broiler chicks. A total of 3,872 day-old chicks were randomly allotted to f…
Abstract The failure of E230 heat‐exchanger in the production of epichlorophydrin (ECH) form dichloropropanol (DCP) was analyzed and material solutions are recommended. The analysis indicates that the combined effect of stress corrosion cracking (SCC) and dissolution of HCl and HClO in the DCP mixture solution in the…
Diffraction gratings with precise spatial periods of 2 ㎛ and 5 ㎛ have been fabricated by using a femtosecond laser which does not have limits on materials of micromachining and small thermal effects due to high peak power. Diffraction angle and diffraction efficiency of those were measured. Simulation results of diffr…
AFIT/GNE/ENP/10-M05 The search for superior nuclear radiation detection materials is ongoing. Current scintillator materials using Thallium doped Sodium Iodide or Cesium Iodide are the benchmarks for ease of use and quick identification of isotope species. This research aims to explore Cesium Bromide doped with 1 % mo…
帝塚山高等学校女子特進コースと奈良教育大学で高大連携事業の一環として、「化学実験」体験講座を実施した。この講座では、理系の大学生活において重要な研究室の状況を知る機会を提供するとともに、基本的な実験操作の確認から大型分析装置（電子スピン共鳴分光;（ESR）法）を用いた実験などを行った。この「化学実験」体験講座に参加した生徒のなかには、自分たちで実験のテーマを設定し、ESRを用いた研究を行う者もいた。また、高校生たちが専門の研究会で発表する機会を得て、実験結果をまとめポスター発表を行った。発表内容は、食品の中に含まれる常磁性遷移金属に関する研究と日焼け止めクリームの紫外線防止効果に関するものである。これら一連の「化学実験」体験講座の…
La perovskite LaCo0.7Cu0.3O3-delta viene sintetizzata e caratterizzata per una sua applicazione come catado e anodo in celle a combustibile a stato solido e temperature intermedie. Si studiano le sue caratteristiche di conduttore ionico e l' attivita catalitica nei confronti di reazioni di steam reforming e steam refo…
