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.

这项研究的目标是对可能影响大气成分的物理、化学和光化学异质过程进行基本测量。 明确真空环境中的光谱技术，用于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。 将进行模型颗粒成分、成核和生长速率、异质化学和光化学反应速率以及凝聚相光学性质的测量。
