A Comprehensive Approach to Understanding Chemistry at Interfaces and Atmospheric Implications

NSF化学部由NSF大气科学部(GEO/ATM)和国际科学与工程办公室(OISE)提供资助，支持Barbra Finlayson-Pitts教授及其合作者在加州大学欧文分校AIR UCI中心的合作研究项目。AIR UCI合作团队将研究与大气过程直接相关的复杂界面过程。这些研究包括研究气体-气溶胶相互作用、气体分子与表面水膜之间的相互作用、表面有机分子与与大气有关的气相氧化剂的相互作用、界面上复杂的有机和无机混合物的光化学、与大气中发现的离子类似的离子物种的光谱以及复杂界面上的酸基平衡。合作团队将利用最先进的理论方法来指导和解释在这些复杂系统中获得的实验结果。在分子水平上了解界面上的过程对于为包括气候变化在内的从局部到全球尺度的大气过程模型提供准确的输入、对于理解并最终防止表面腐蚀、对于阐明包括生物界面的材料上的过程以及对于理解水和土壤上的过程是至关重要的。这项研究还将为下一代科学家提供最先进的实验和理论研究方面的前沿培训，这些实验和理论研究旨在提高我们对大气过程的理解。与国际合作者和国家实验室的交流机会将为他们的培训提供重要和不同寻常的广度。很大比例的受训人员将来自代表性不足的群体。这项研究的广泛范围及其在空气污染和气候变化方面的应用将用于通过一个为期两周的暑期教师讲习班来教育初中/高中水平的科学教师，该讲习班可能会对每年3000-4000名学生产生影响。

The NSF Division of Chemistry with contributions from the NSF Division of Atmospheric Sciences (GEO/ATM) and the Office of International Science and Engineering (OISE) supports the collaborative research project of Prof. Barbra Finlayson-Pitts and her collaborators at the air UCI Center at the University of California at Irvine. The air UCI collaborative team will study complex interfacial processes that are directly relevant to atmospheric processes. These include studies of gas-aerosol interactions, interactions between gas molecules and water films on surfaces, interactions of organic molecules on surfaces with atmospherically relevant gas phase oxidants, the photochemistry of complex organic and inorganic mixtures at interfaces, the spectroscopy of ionic species similar to those found in the atmosphere, and acid-based equilibria at complex interfaces. The collaborative team will utilize state of the art theoretical methods to guide and interpret the experimental results obtained in these complex systems. Molecular-level understanding of processes at interfaces is critical for providing accurate inputs for models of atmospheric processes from local to global scales including climate change, for understanding and ultimately preventing corrosion of surfaces, for elucidating processes on materials that include biological interfaces, and for understanding processes on water and soils. The study will also provide cutting-edge training of the next generation of scientists in state-of-the-art experiments and theory studies that are designed to improve our understanding of atmospheric processes. Exchange opportunities with international collaborators and the national labs will provide significant and unusual breadth to their training. A high percentage of the trainees will be from underrepresented groups. The broad scope of this research and its application to air pollution and climate change will be used to educate middle/high school level science teachers through a two week summer teacher workshop that will potentially have impact on 3000 - 4000 students per year.
