The focus of this NIRT project on Investigating Nano-carbon Particles in the Atmosphere: Formation and Transormation is to gain a clearer understanding of the chemical and physical processes occurring in the formation of carbon nanoparticles and their subsequent transformation in the diesel engine exhaust. The project has three thrust areas: (1) development of theoretical and experimental methodologies to describe the formation of heavier hydrocarbons and particle inception; (2) modeling and measurement of the particle size distribution of nanoparticles formed in combustion and diesel exhaust; and (3) modeling of the optical properties of soot precursors an soot as it ages. This project includes a collaboration with the University of Naples, Italy. The Italian investigators will contribute to this activity by several measurements including optical measurements in flames, and conagulation models.

这个NIRT项目的重点是研究大气中的纳米碳颗粒：形成和转化，以更清楚地了解碳纳米颗粒形成过程中发生的化学和物理过程及其随后在柴油发动机排气中的转化。 该项目有三个重点领域：（1）开发理论和实验方法来描述较重碳氢化合物的形成和颗粒初始;（2）燃烧和柴油机废气中形成的纳米颗粒的粒度分布的建模和测量;以及（3）烟尘前体的光学特性建模。 该项目包括与意大利那不勒斯大学的合作。 意大利调查人员将通过几项测量，包括火焰中的光学测量和凝聚模型，为这项活动作出贡献。
