Intercalation-Control and Establishment of Reaction Sites

“插层”包括各种客体分子与主体材料之间的离子和/或电荷的相互作用和转移，这些离子和/或电荷是自然的或人工产生的拓扑定向反应的结果，并提供固溶体、相变和催化活性。在本项目中，根据“控制和建立反应场所”的原则，各科学领域的各种研究人员齐聚一堂，全面讨论了开发高功能插层材料的基本思路。会议于1996年12月26-27日在静冈县沼津的KKR“Hamayuu”举行，有27名成员。在这次会议上，讨论了下列主题：1)离子-电子混合导体中的电子传输，2)利用穆斯堡尔效应跟踪铁的价态变化，3)不同固体电解质之间的异质结在传感器中的应用，4)插入到具有强电子相互作用的材料中，5)层状钙钛矿型复合氧化物的光催化活性，6)通过机械合金化方法合成具有低维结构的金属硫系化合物，7)锂或氢嵌入碳材料，8)锂在尖晶石氧化物中的扩散，9)与锂锰氧化物有关的新型正极材料，10)锂在锂过渡金属氮化物中的插层，11)锂插层石墨表面的STM观察等。在讨论中，强烈指出了不同学科之间相互关系的多样性，并再次认识到这种讨论的重要性。

"Intercalation" includes interactions and transfer of ions and/or charge between various guest molecules and host materials which are natural or artificially produced as the results of topotactic reactions, and provides solid-solutions, phase transformation, and catalytic activities. In the present Project, on the basis of the principle of the "Control and Establishment of Reaction Sites", varieties of investigators in wide range of scientific fields have gathered together, and totally discussed about the basic idea to develop highly functional intercalation materials.The meeting was held on December 26-27,1996 in KKR "Hamayuu" located in Numazu, Shizuoka-Prefecture, with 27 members. In this meeting, following subjects have been discussed : 1) transport of electron in ion-electron mixed conductor, 2) trace of the change in the valence sate of iron using Mossbauer effect, 3) application of hetero-junction between different solid elctrolyte to sensors, 4) intercalation into materials showing strong electron nteraction, 5) photo catalytical activity of layred perovskite type composite oxides, 6) synthesis of metal chalcogenides having low dimensional structure by means of mechanical alloying method, 7) intercalation of lithium or hydrogen into carbon materials, 8) diffusion of lithium in spinel oxides, 9) novel cathode materials related to lithium-manganese oxide, 10) intercalation of lithium into lithium-transition metal nitrides, 11) STM observation of graphite surface intercalated with lithium, and so on.Among the discussion, varity of mutual relationship between different subjects have been strongly pointed out, and the importance of this kind of discussion have, again, recognized.
