这项研究的目标是对可能影响我们大气组成的物理、化学和光化学不均匀过程进行基本测量。在定义明确的真空环境中使用光谱技术来表征大气气溶胶的生长和反应性。实验将在模型薄膜样品和我们在实验室制造的实际颗粒上进行。将进行模型颗粒组成、成核和生长速率、非均相化学反应和光化学反应速率以及凝聚相光学性质的测量。

The goal of this research is to make fundamental measurements of physical, chemical and photochemical heterogeneous processes that could affect the composition of our atmosphere. Spectroscopic techniques in well-defined vacuum environments to characterize the growth and reactivity of atmospheric aerosols. Experiments will be performed both on model thin-film samples and on actual particles we fabricate in the laboratory. Measurements of model particle composition, nucleation and growth rates, heterogeneous chemical and photochemical reaction rates, and condensed-phase optical properties will be carried out.
