本研究では、次期学習指導要領で求められている理数教育の充実や学びの質を高める方法として、得られた実験データをグラフ化する取り組みを行った。そして、このグラフを使って、日常生活で見られる自然現象を明らかにしようとした。この実践例について紹介する。

Electroviscous effect of an ionic liquid (1-methyl-3propyl imidazolinium iodide) in ethylisopropylsulfone is measured using capillary action in which the capillary filling speed is depend on viscosity of the sample. Rectangular capillary cells are prepared with two indium-tin oxide coated glasses and polyimide film spacers. The electrodes allow us to measure the electroviscous effect of the sample. The results of electro viscous measurements clearly show voltage dependence in which the application of voltage slows the capillary filling speed. The theoretical analysis of the capillary action is also performed. The calculated results show a well agreement with the experimental results., イオン液体は高いイオン電導性から、電気二重層キャパシタ、色素増感太陽電池、燃料電池、リチウムイオン電池などへの応用が期待されている。また、イオン液体は、優れた電気特性だけでなく、難燃性・不揮発性も有するため、安全性も同時に兼ね備えた材料である。本論文では、イオン液体l-methyl-3propyl imidazolinium iodideとethylisopropylsulfoneの混合溶液の電気粘性効果を調べている。電気粘性効果は、ITOガラス2枚からなるセルを作製し、溶液を注入したときの液先端速度の電圧依存から測定している。また、理論解析よる矩形断面をもつキャピラリー構造における溶液注入時の液先端速度および液先端位置の検討も行っている。

application/pdf, This case study in Cape Verde is a part of the European Research Network's activities and evolved from our idea of constructing, against the tide of globalization, a “codevelopment” system for the 21st century planetary society, in which the problems of exclusion are increasingly frequent. It seeks to clarify the ways in which “wisdom for codevelopment” is lived and embodied in “frontier” or “liminal” territories, which themselves try to coexist while conflicting, merging, amalgamating, and intertwining with one another. Under such objectives, I conducted research and interviews in certain areas, regarding the autonomy and independence of such localities, the global inter-cooperation among the communities, and the composite/complex/hybrid identities of the community residents, while employing such key concepts as “metamorphosis” and “liminality.”
