PECASE: Teaching and Research: A Unified Approach to the Role of Particles in Atmospheric Chemistry

9733629马丁这个项目是在回应职业生涯计划招标提交。 这是一个集研究和教学目标于一体的五年职业发展计划，主要科学目标是为内部混合的无机大气气溶胶粒子的相变（固体或液体）提供定量过程模型。 该模型将考虑水溶性化合物（例如，硫酸铵）和水不溶性化学物质（例如，二氧化钛）。 将进行一系列的实验室实验，以提供经验输入的过程模型。 研究人员将研究混合相气溶胶颗粒的风化、潮解和冻结特性。 红外光谱（IR）将用于研究内部混合气溶胶系统的相变。教育计划包括三个目标：（1）课程开发，以产生两个新的课程;（2）教学工具开发，包括一个与互联网相连的表面化学电子教学模块;（3）本科生研究培训。 作为教学活动的一部分，提出了两项创新：（1）两名本科生的暑期研究经验;（2）将基于互联网的技术作为课程内容的一部分。 夏季研究经验将包括研究方法的夏季短期课程。 暑期研究的结果将以电子格式直接与新课程联系起来。

9733629MartinThis project was submitted in response to the CAREER Program solicitation. It is a five-year career development plan that integrates research and teaching goals.The major scientific objective is to provide a quantitative process model for the phase changes (solid or liquid) of internally mixed inorganic atmospheric aerosol particles. The model will consider water-soluble compounds (e.g., ammonium sulfate) and water-insoluble chemical substances (e.g., titanium dioxide). A series of laboratory experiments will be carried out to provide empirical input to the process model. The investigator will study the efflorescence, the deliquescence, and freezing properties of the mixed-phase aerosol particles. Infrared spectroscopy (IR) will be used to investigate phase transformations of the internally mixed aerosol systems.The educational plan consists of three goals: (1) curriculum development to produce two new courses; (2) instructional tool development to consist of an electronic teaching module on surface chemistry that is linked to the internet; and (3) undergraduate research training. Two innovations proposed as part of the teaching activities are: (1) a summer research experience for two undergraduate students; and (2) incorporation of internet-based technology as part of the course content. The summer research experience will include a summer short course on research methodology. Results from the summer research will be linked directly in electronic format to the new courses.
