This presidential Young Investigator award encompasses three projects in the general area of ceramic and zeolite chemistry. One of these concerns mass-transport limitations in sol-gel synthesis; the rates of diffusion of small and large precursors in viscous reacting systems. Another is the diffusion of guest molecules in zeolites and the influences thereon of zeolites structure, crystal defects and cation occupancy; both theory and experiment are applied. The other project is a study of the chemistry and kinetic behavior of polyoxoanions, the precursors to zeolite-like materials and most ceramics; silicates, aluminates, borates, phosphates, and ferrites are studied. A variety of techniques, both experimental and computational, are employed, with an emphasis on nuclear magnetic resonance methods. This effort is directly applicable to the synthesis and processing of zeolites, zeolite-like materials, and ceramics in general. Some of it may also have application in polymer synthesis and processing and in processing of glasses and thin films.

该总统青年研究员奖涵盖陶瓷和沸石化学领域的三个项目。 其中之一涉及溶胶-凝胶合成中的传质限制；粘性反应系统中小型和大型前体的扩散速率。 另一个是客体分子在沸石中的扩散以及沸石结构、晶体缺陷和阳离子占有率对其的影响；理论和实验均得到应用。 另一个项目是研究多氧阴离子的化学和动力学行为，多氧阴离子是类沸石材料和大多数陶瓷的前体；研究了硅酸盐、铝酸盐、硼酸盐、磷酸盐和铁氧体。 采用了多种实验和计算技术，重点是核磁共振方法。 这项工作可直接应用于沸石、沸石类材料和陶瓷的合成和加工。 其中一些还可以应用于聚合物合成和加工以及玻璃和薄膜的加工。
