The behaviour of complex fluids is fundamentally interesting and important in many applications. This thesis reports on three experiments on the thermal and rheological behaviour of complex fluids. The first is a study of the rheological properties of and heat transport in a saline solution of hydroxyethyl cellulose.…
Asian Journal of Organic & Medicinal Chemistry includes communications, full papers (articles), short papers, green chemistry, reviews, and perspectives. Specifically, these include synthesis, synthetic methods and regents, mechanism of reactions, biologically active compounds with their possible mechanism of action,…
This research was carried out to separate of polyoxo-anions, P2Mo5, Mo7 and Mo8, by Capillary electrophoresis. The equilibrium conditions, stability and solubility of these polyoxoanions are also studied. The equilibrium depends both on the concentration and pH of the solution. Counter ions have also an effect on the…
The charge-density-wave (CDW) phase is a macroscopic quantum state consisting of a periodic modulation of the electronic charge density which is accompanied by a periodic distortion of the atomic lattice in quasi-one-dimensional (1D) or layered quasi-two-dimensional (2D) metallic crystals. Several layered transition m…
Since the discovery of piezoelectric ceramic materials in the mid-20th century, piezoelectric materials have become an important research field and is currently used in a whole range of applications such as sensors and actuators. The most important piezoelectric materials today are those based on the lead containing p…
Mechanochemistry is increasingly used for synthesizing soft matter materials including metal organic compounds and cocrystals.1,2 The ever-increasing interest in this method is contrasted by a limited mechanistic understanding of the mechanochemical reactivity and selectivity. Time-resolved in situ investigations of m…
This study investigates the effect of single jersey, based on its original formas a cylinder. It is also an investigation of color and transforming surfaceof garment.The outfits are based on the cylinder in construction. With some cuts andseams, developed into garments. The surface of the fabric has qualities recogniz…
In recent years, with the rapid development of China's wire and cable industry, optical cable demand gradually increased, but the wire and cable water resistance is not good, and vulnerable to corrosion caused by the distortion of the optical signal, so the cable aluminum-plastic composite belt should be born. In this…
急激に高齢化あるいは複雑化する社会への対応に向け，医療，食品安全，テロ対策など多岐にわたる分野において，マーカー分子などの標的物質を素早く正確に検出するバイオセンサーの開発に期待が寄せられている。とくに，蛍光剤や酵素などの標識なく，標的物質の結合にともなう光学的変化の非標識（ラベルフリー）計測が可能なプラズモンバイオセンサーの研究が盛んである。しかしながら，バイオセンシングの性格上，センサー基板はディスポーザブルとする必要があり，センサー基板作製の煩雑さの解消も課題である。この点を考慮し，ナノインプリント技術を利用したプラズモンバイオセンサーチップの開発を検討した例を紹介する。加えて，多項目網羅解析の必要性から，ハイパースペクトル…

Solid oxide cells (SOCs) oer great prospects for the ecient and reversible conversion of chemical to electrical energy. Therefore, they are expected to play a key role in the renewable energy landscape. However, their limited lifetime under operating conditions hinders their widespread usage. The degradation processes…
There are many process parameters that are important in automated composite manufacturing, starting with the handling of fabrics in the preforming process. Characterization of fabrics on their preforming qualities – which will be referred to as drapability in this paper – is necessary to tune the manufacturing process…
