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

9733629马丁这个项目是应职业计划征集而提交的。这是一个集研究和教学目标于一体的五年职业发展计划。主要的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)提供一个定量的过程模型。该模型将考虑水溶性化合物(例如，硫酸铵)和不溶于水的化学物质(例如，二氧化钛)。将进行一系列实验室实验，为过程模型提供经验输入。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。红外光谱学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，以产生两门新课程；(2)教学工具开发，包括连接到互联网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，建议的两项创新是：(1)为两名本科生提供暑期研究体验；(2)将基于互联网的技术纳入课程内容。暑期研究体验将包括一个关于研究方法的暑期短期课程。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.
