Assembly of Lamellar Materials from Nanoscale and Molecular Building Blocks

这个奖项给宾夕法尼亚州立大学是一个较早的一个更新，并在化学部和材料研究部的固态化学计划的先进材料和加工程序的支持。 在这个项目中，托马斯Mallouk将研究一个基于溶液的形成键合钙钛矿薄膜和纳米晶体管通过逐层生长和剥离在不同的反应条件。 层状固体的拓扑化学脱水和还原反应将用于制备具有三维外延有序的三维键合钙钛矿。 这些过渡金属氧化物的超分子组件将被评估的离子，电子，巨磁电阻和铁电性能。 该研究计划亦将为学生提供材料化学的教育和培训机会。根据该计划，将由金属氧化物制备具有特定尺寸、形状和组成的三维薄膜和纳米管，以应用于分子电子学、纳米机器和相关应用。使用湿化学方法合成这些超分子组装体，一旦完全开发，可以提供替代传统方法（例如化学气相沉积和激光烧蚀）的具有成本效益的方法。此外，该研究计划将为学生提供材料化学教育和培训机会。

This award to Pennsylvania State University is a renewal of an earlier one, and is supported by the Advanced Materials and Processing Program in the Chemistry Division and the Solid State Chemistry Program in the Materials Research Division. In this project, Thomas Mallouk will study a solution-based formation of bonded perovskite thin films and nanocrystalline tubes by layer-by-layer growth and exfoliation at different reaction conditions. Topochemical dehydration and reduction reactions of the lamellar solids will be used to prepare three-dimensional bonded perovskites with three-dimensional epitaxial ordering. These supermolecular assemblies from transition metal oxides will be evaluated for ionic, electronic, colossal magnetoresistance and ferroelectric properties. The research program will also provide education and training opportunity in materials chemistry to students.Under the award, three-dimensional thins films and nanotubes with defined size, shape and composition will be prepared from metal oxides for potential applications in molecular electronics, nanoscale machines and related applications. Synthesis of these supermolecular assemblies using wet chemistry methods, once fully developed, may provide alternate cost-effective methods to the traditional procedures such as chemical vapor deposition and laser ablation. In addition, the research program will provide education and training opportunity in materials chemistry to students.
