The anode properties of SiO-C electrode materials [SiO-C:α-Fe2O3 = x:100 − x (wt%)] containing α-Fe2O3 fine powder (spherical particles, ca. 0.16 µm) as the additive were investigated in a lithium cell using lithium metal as the counter electrode. It was observed by scanning electron microscopy (SEM) that spherical α-…
Overhead lines (OHL) operating at 400kV, form the backbone of CLP Power's transmission network. Unlike underground cables, overhead lines are vulnerable to external environmental attacks, such as adverse weather, high humidity, pollution, ground stability, vegetation, and flying objects etc. To ensure high reliability…
本研究では，硝酸酸化とその後の脱気処理により，細孔構造が同等で異なる表面酸性官能基量をもつ活性炭を調製し，それらを吸着剤として用いて11種類の芳香族化合物の吸着実験を行った．吸着実験を通じ，活性炭表面の酸性官能基の有無と，吸着質として用いた芳香族化合物の芳香環に結合した置換基のもつ性質が，吸着に及ぼす影響を調べるとともに，吸着形態を考察した．表面酸性官能基をもつ活性炭（DAOx）は，官能基をもたない活性炭（DAOxOG）よりも，芳香族化合物に対する吸着親和力が小さいことがわかった．しかし，ニトロベンゼンのような双極子モーメントの大きい芳香族化合物は，フェノールのような双極子モーメントの小さい芳香族化合物とは対照的に，溶質が高濃度に…
We report changes in the degrees of tri-axial orientation as functions of applied magnetic field and rotation rate for Y2Ba4Cu7Oy powder samples oriented in epoxy resin under modulated rotating magnetic fields (MRFs). Although the degrees of orientation were reduced for the decrease in both applied field and rotation…
以巯基小分子为配体水相合成CdTe量子点, 通过调节回流时间调控其粒径大小. 由于量子点的宽谱激发特性, 在蓝光(473 nm)或绿光(532 nm)条件下, 纳米金属薄膜表面不同发射波长的CdTe量子点均可被激发而与金属表面等离子体发生耦合相互作用, 从而在棱镜一侧发出高度定向的偏振荧光, 其荧光特性与样品厚度密切相关. 表面等离子体耦合荧光发射法(SPCE)具有波长分辨性质, 不同颜色的量子点在不同角度定向发射, 发射波长越长, 角度越小. 720 nm和630 nm量子点的自由空间发射荧光光谱呈现交叠, 然而, 基于SPCE的波长分辨性质, 我们通过改变检测角度避开光谱重叠, 在棱镜一侧的43o和51o处分别得到了两种量子点…
Acrylonitrile butadiene rubber (NBR, 35 % acrylonitrile contents) cure processing was carried out at different temperatures by rheometer. Surface and cut-surface functional groups were analyzed by X-ray photoelectron spectroscopy (XPS). Surface and cut-surface O element quantities of NBR cured at 140 °C were almost th…

As new possibility for inrush current phenomena analysis a new simulation model with possibility of analysis inrush current for different switch times, harmonic analysis of inrush current waveform, different ground connections of transformer and influence of inrush current when transformers work in parallel (mutual ef…
According to the tool path characters of non-cylindrical hole precision machining by giant magnetostrictive components,a dynamic hysteresis model of giant magnetostrictive components was established by a pure delay transfer function and the linearity model between high-frequency driving currents and micro-displacement…
The yarn thickness has been defined in the relationship between length and weight of the yarn. However, the appearance width (diameter) of the yarn plays an important role in the dimension of knit wear products. In addition, the appearance width is related with final twist number and affects yarn properties. In this s…

機能性色素を用いた太陽電池は有機薄膜型および色素増感型が知られており，製造のしやすさから色素増感型が主流になりつつある。このような機能性色素としてフタロシアニン（PC）が注目されている。PCはQ帯と呼ばれる最高被占軌道－最低空軌道間のπ-π*遷移に基づく600～650 nm付近に極大吸収を有している。Q帯はPCのπ電子共役系を伸長することによって長波長側へ伸長することが可能であるが，さらにノン－ペリフェラル位に置換基を導入することおよびポルフィラジン環構造を歪ませることによって近赤外領域へシフトすることが報告されている。そこで本研究では，ここでは太陽電池などのデバイスとして用いることを前提とした新規の近赤外領域に吸収をもつPCとし…
