The primary aim of this research is to investigate the mechanism of solid state chemical reactions at the atomic level. High- resolution electron microscopy (HREM), analytical electron microscopy (AEM), and associated techniques are used because of their adequate lateral and temporal resolutions. The chemical and structural evolution of the amorphous gel to the crystalline ceramic will be examined along with structural and dynamic studies of intercalated low-dimensional materials, and the complex oxide systems of the rare earths and doped zirconia. These studies are important in developing new materials such as structural ceramics, fast ion conductors, and sensors.

本研究的主要目的是探讨 原子水平上的固态化学反应。 高- 解析电子显微镜（HREM），分析电子显微镜 显微镜（AEM）和相关技术的使用，因为 其足够的横向和时间分辨率。 化学和 无定形凝胶到结晶的结构演化 陶瓷将沿着进行结构和动力学研究 嵌入低维材料，复合氧化物 稀土和掺杂氧化锆的体系。 这些研究 在开发诸如结构陶瓷的新材料方面很重要， 快离子导体和传感器。
