This Faculty Early Career Development (CAREER) project, supported in the Analytical and Surface Chemistry Program, aims to focus on the synthesis and characterization of stable thin films that will be suspended across microfabricated structures. During the tenure of this four-year continuing grant, Professor Fritsch- Faules and her students at the University of Arkansas will test these structures for application in novel devices for sensing and for biomimetric applications. Submicron structures will be constructed to support suspended films such as artificial biomembranes. The inorganic substrates will be both insulators and conductors depending upon the particular function they are intended to serve in these structures. Studies of these surface- confined materials will probe their stability and function with variables including electric field strength, solvent character and ionic composition of these systems. Professor Fritsch-Faules will include a host of activities that are designed to involve students in the K-12 grades. Educating these students in the high-order thinking abilities and problem-solving skills that are part of science and mathematics will be emphasized. Community Access Television and the World Wide Web will be used to disseminate such programs to diverse audiences. The ability to construct new three-dimensional microfabricated structures with wells having geometries for supporting suspended thin films will be an important outcome of this CAREER research project. The characterization of these suspended thin films will be a challenging scientific and engineering problem that depends on Professor Fritsch-Faules' unique background in electroanalytical chemistry and in microfabrication science. Her integrated educational plan is no less ambitious and it has the potential for immense societal impact upon the K-12 students in her immediate geographic area in the near-term and upon a much more broadly distributed cohort in the long-term.

这个由分析和表面化学项目支持的教师早期职业发展（Career）项目，旨在专注于将悬浮在微制造结构上的稳定薄膜的合成和表征。在这项为期四年的持续资助期间，Fritsch- Faules教授和她在阿肯色大学的学生将测试这些结构在新型传感设备和生物识别应用中的应用。将构建亚微米结构来支持悬浮膜，如人工生物膜。无机衬底将是绝缘体和导体，这取决于它们打算在这些结构中服务的特定功能。这些表面约束材料的研究将探讨其稳定性和功能变量，包括电场强度、溶剂性质和离子组成。Fritsch-Faules教授将包括一系列旨在让K-12年级的学生参与的活动。教育这些学生的高级思维能力和解决问题的能力是科学和数学的一部分，将得到强调。社区电视和万维网将被用来向不同的观众传播这些节目。构建具有支撑悬浮薄膜的几何形状的井的新型三维微加工结构的能力将是该CAREER研究项目的重要成果。这些悬浮薄膜的表征将是一个具有挑战性的科学和工程问题，这取决于Fritsch-Faules教授在电分析化学和微加工科学方面的独特背景。她的综合教育计划同样雄心勃勃，它有可能在短期内对她所在地理区域的K-12学生产生巨大的社会影响，并在长期内对更广泛分布的群体产生影响。
