Topological insulators are electronic phases that insulate in the bulk and accommodate a peculiar, metallic edge liquid with a spin-dependent dispersion. They are regarded to be of considerable future use in spintronics and for quantum computation. Besides determining the intrinsic properties of this rather novel elec…
Objective. Power and industry systems include Printed Circuit Board（PCB）and Main Power Component（MPC）such as power semiconductor device. The researcher of Life Cycle Inventory（LCI）often faces the difficulty in collection of the required data for PCB which is comprised of a large number of parts and MPC of special spec…

Understanding the molecular mechanisms of cancer is the key for transforming cancer medicine. A substantial proportion of human genes show alternative splicing and mis-regulation of Pre-mRNA splicing is seen in several cancers. This book further investigates these matters. The first few chapters provide an update on t…
軽量で，電池による駆動が可能なハンドヘルド型蛍光X線分析計（HHXRF）を用い，作業環境空気中の二酸化チタン濃度を迅速に測定する方法を検討した．二酸化チタンのブタノール懸濁液をメンブランフィルターでろ過して調製した模擬試料を測定試料とし，精密測定可能な卓上型蛍光X線分析計（卓上型）とHHXRFの測定結果を比較した．HHXRF測定は，合金種判定用のファンダメンタルパラメータ（FP）計算を行う機種を使用し，フィルター試料をチタンを含まない金属板（補助金属板）の上にのせ，チタンを補助金属板の微量不純物と装置に認識させ測定する方法で測定を試みた．予備検討により，補助金属板として銅を選択した．卓上型とHHXRFの測定結果はほぼ一致した．HH…

O presente trabalho foi desenvolvido com o objetivo de investigar os esforcos eletromecânicos que atuam nos enrolamentos de um transformador de potencia no momento da energizacao do equipamento. Metodos analiticos e computacionais foram utilizados para determinacao dos esforcos eletromecânicos em um transformador trif…
Ionic transport of alkali was investigated in the SiO2–B2O3–R2O glass system (with R = Li, Na, K or Cs) by using impedance spectroscopy measurements at the glassy state. Transport mechanisms are also understood on the basis of glass structural analysis, such as X-ray total scattering and Raman spectroscopy, which help…
Carbon nanodots(C-dots) are fascinating carbon materials that are attracting increasing interest because they have distinct benefits, such as chemical inertness, low cytotoxicity, a lack of optical blinking and excellent biocompatibility, compared with organic dyes and other semiconductor nanodots with heavy metal cor…
Mit Hilfe des KorroPad-Prufverfahrens konnten verschiedene umgebungs- sowie prozessbedingte Einflusse in Parameterstudien gezielt untersucht werden. So konnte der negative Einfluss von korundbasierten Schleifmitteln auf die Passivschichtausbildung nachgewiesen werden. Weiterhin konnte mittels KorroPad die Wirksamkeit…
This work determines and compares the allowable torque and the maximum torque for tightening the bolt in Friction Drilling process applied for different thin walled materials. Five different thin walled materials were analysed, i.e. S235JR Steel, DC06 Steel, Aluminium alloy, Copper and Titanium thin walled plates, all…
The key objective of this paper is to give a detailed account on rehabilitation of RC beams by means of a composite created with natural fibre called jute. For the sake of experimentation, seven un...
The coarse-grained non-equilibrium molecular dynamics simulations were performed to investigate the capillary evaporation of water adsorbed on hydrophilic nanopores. The ELBA water model was implemented. To assess the effect of hydrophilicity, three hydrophilic nanoporous thin films, which made of fixed water molecule…
2011年以降の高校化学教科書には発展的内容として標準電極電位が導入されたが, 高校教員自身が大学で電気化学を選択履修していないケースも多く, 電極反応の条件を高校生に指導するには実験教材の開発と指導法の工夫が必要である。しかし, 1950年代から現在までの高校化学の教科書の電極反応に関する記述を調査したところ, 電気分解実験で扱われる溶液は水や塩化銅（Ⅱ）溶液に限られており, それぞれの電極で気体発生のみか金属析出のみを観察することになる。今回開発したペットボトルとプラスチック注射器等の簡便な実験装置は, 金属析出量と気体発生量を同時に測定可能で, ニッケルめっき（電気分解）の陰極は水素発生とニッケル析出が競合して起こる。得られ…
We fabricated hybrid white organic light-emitting diodes, which was deposited by three materials co-deposition with bis[2-(diphenylphosphino) phenyl]ether oxide (DPEPO), bis[4-(9,9-dimethyl-9,10-dihydroacridine) phenyl]sulfone (DMAC-DPS), iridium(III) bis(4-phenylthieno[3,2-c] pyridine)acetylacetonate (PO-01). The DMA…
The long-term stabilities of polymer solar cells (PSCs) are key requirements for commercialization, but progress has been limited in this area. Most PSCs are not stable as subsequent exposure to heat which drives further macrophase separation at the micrometer scale and environmental stress that causes the mechanical…
An electrode for electric double layer capacitor (EDLC) is prepared from pitch-based activated carbon fibers (ACFs) modified by fluorination and oxyfluorination. The fluorination and oxyfluorination of pitch-based ACFs are carried out with F2:N2 ratios of 1:9, 2:8, 3:7 and F2:O2 ratios of 3:7, 5:5, 7:3, respectively.…
The blends of poly(2,6-dimethyl-1,4-phenylene ether) (PPE)/nylon 66 composites with compatibilizer were prepared by melt compounding. Halogen free flame retardant, phosphinate was incorporated into the compatibilized blends. The impact and tensile strength were deteriorated with increasing the flame retardant while th…
