This Professional Opportunities for Women in Research and Education (POWRE) project addresses fabrication and characterization of ultrafine grained (Ba,Sr)TiO3 (BST) and related materials, such as BaTiO3 (BT) and SrTiO3 (ST) as sputtering targets using a reactive process. These materials in thin film condition are very important dielectric constituents for the next generation computer chips. These sputtering targets are used in producing thin films. It is proposed to trigger these reactive processes in pressed powder compacts using a hot wire. The thermodynamics, kinetic studies as well as reaction mechanism studies will be performed. The microstructure will be characterized and correlated to the processing parameters. The reactive process is economical, uses inexpensive raw materials, and has low energy requirement. The reactive process also has possibilities of industrial scaling up. This is important to the career development potential for this new Principle Investigator in starting up her career. The education component of the work will focus mainly on two activities: modification of an existing material processing course for the senior/graduate students and involvement of undergraduates to the advanced processing research area. It is expected that this POWRE project will provide opportunities for future research with significant industrial interest, allowing this new faculty member to focus on a new set of materials while advancing her expertise in the thin film deposition area.

该研究和教育领域女性专业机会（POWRE）项目涉及超细晶粒（Ba，Sr）TiO 3（BST）和相关材料的制造和表征，如BaTiO 3（BT）和SrTiO 3（ST）作为溅射靶，使用反应工艺。 这些薄膜材料是下一代计算机芯片中非常重要的电介质成分。 这些溅射靶用于生产薄膜。 建议使用热线在压制的粉末压坯中触发这些反应过程。 进行热力学、动力学以及反应机理的研究。 微观结构将被表征并与加工参数相关联。 反应过程是经济的，使用廉价的原材料，并且具有低的能量需求。 反应过程也具有工业放大的可能性。 这对这位新的首席调查员在开始职业生涯时的职业发展潜力很重要。教育部分的工作将主要集中在两个活动：修改现有的材料加工课程的高年级/研究生和本科生参与先进的加工研究领域。预计这个POWRE项目将为未来的研究提供机会，具有重大的工业利益，使这位新的教师能够专注于一组新的材料，同时提高她在薄膜沉积领域的专业知识。
