This chapter reviews the literature published on macrocyclic coordination chemistry during 2011. The aim is to describe the key advances, focusing predominantly on complexes formed with transition metal and lanthanide ions. Porphyrin ligands and supramolecular chemistry are not covered. Trends in the development of ma…
The electrical properties of chrome nitride (Cr–N) films have been investigated for application to cryogenic temperature sensors. The films were deposited on silica substrates by RF magnetron sputtering under various total pressures without substrate heating. The electrical resistivity at room temperature increased fr…
亜鉛めっき鋼板では，切断端面の亜鉛が早期に消失する端面腐食と呼ばれる問題がある．端面腐食は，薄い液膜が付着した環境下でのガルバニック腐食であると考えられ，このメカニズムを解明するための数値解析モデルを開発した．薄液膜下の腐食速度は，大気からの酸素供給量により律速されるため，液膜中の酸素濃度を考慮する必要がある．また，従来の数値解析モデルでは，電位と電流密度分布の情報しか得られない．腐食メカニズム解明のためには，イオン濃度，pH分布や腐食生成物分布を知ることが重要であり，これらを考慮したモデルを開発した．本モデルによる計算方法と計算結果例について詳しく報告する．
High-quality epitaxial graphene has been a continuous focus of research interest owing to its viable device applications. Epitaxial graphene growth on silicon (Si) substrates is of great interest for its application to electronics. Here, we report experimental findings of atmospheric-pressure-grown epitaxial graphene…
The residual stresses present through the quenching, ageing, and machining processes in sub-scale forgings of RR1000 have been measured experimentally using neutron diffraction, and the contour method. The forgings, 88.9mm in diameter, and 25.4-50.8mm thickness, were of small enough geometry to allow neutron strain me…
2011年12月，政府は電源別発電コスト試算結果の報告書を公表した。原子力発電のコストは8．9円/kWh以上であり，石炭火力9．5～9．7円/kWh，LNG火力10．7～11．1円/kWhと比較しても遜色ない。再生可能エネルギーについてはおおむね，まだ原子力・火力より割高なものの，今後のコスト低減見通しもあるとされている。エネルギー間の経済性比較の際には，試算に含まれる不確実性を考慮した冷静で合理的な分析姿勢が望まれる。
Large quantities of weapon grade (WG) plutonium have been accumulated in the nuclear warheads. Plutonium and heavy water moderator can give a good combination with respect to neutron economy. TRISO type fuel can withstand very high fuel burn up levels. The paper investigates the prospects of utilization of TRISO fuel…
It is well known that Nd-Fe-B magnet shows high performance as permanent magnets. It has been applied for various products such as sensors, actuators, and the motors for hybrid and electric vehicles, because of its high magnetocrystalline anisotropy and high saturation magnetization. From environmental issues, further…
Four different alum shale waste products (unprocessed shale, weathered fines, processed shale and shale ash) from Kvarntorp, Sweden, were leached at different temperatures (-18°C, +22°C and +70°C) in order to elucidate the influence from freezing (frost wedging) and high temperatures (heat generated during sulfide oxi…
A new series of metal complexes of N′-(5-(4-chlorophenyl)diazenyl)-2-hydroxybenzylidene)-2-hydro xybenzo-hydrazide (H3 L) have been synthesized and characterized by elemental, 1 H-NMR, IR, UV-Vis., ESR, magnetic, thermal analyses (TG) and conductivit
Organ printing, among different tissue engineering innovations, is a layer-by-layer additive fabrication approach for making three-dimensional (3D) tissue and organ constructs using cellular spheroids or bioink as building blocks. The capability to fabricate 3D cellular tubes is the first step as well as an important…
Posttranslational modifications of single-stranded DNA-binding proteins (SSBs), which are essential proteins in DNA metabolism, have been reported from prokaryotic to eukaryotic systems. While eukaryotic SSBs are regulated by phosphorylation on serine and threonine residues, bacterial SSB proteins are also phosphoryla…
This paper proposes a new approach to recover 3-D shape from a SEM image. When SEM image is used to recover 3-D shape, one can apply the algorithm based on the solving the Eikonal equation with Fast Marching Method (FMM). However, when the vertical and oblique light source image is observed, the correct shape cannot b…
