NIRT: Investigating Nano-carbon Particles in the Atmosphere: Formation and Transformation

这项NIRT项目的重点是研究大气中的纳米碳颗粒：形成和转化，目的是更清楚地了解碳纳米颗粒形成及其随后在柴油发动机废气中转化的化学和物理过程。该项目有三个重点领域：(1)发展理论和实验方法，以描述较重碳氢化合物的形成和颗粒的形成；(2)模拟和测量了燃烧和柴油尾气中形成的纳米颗粒的粒径分布；(3)烟灰前体和烟灰老化过程的光学特性建模。该项目包括与意大利那不勒斯大学的合作。意大利研究人员将通过几项测量为这项活动做出贡献，包括火焰中的光学测量和凝结模型。

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.
