A smog chamber for studies of the photochemical degradation of chemicals in the presence of aerosols
TL;DR: In this paper, a smog chamber was designed for the simulation of the tropospheric photochemical degradation of chemicals adsorbed on aerosol surfaces, and the results of experiments on the degradation of simple alkanes (up to n-nonane) and aromatics in the absence and presence of aerosols (SiO2 and TiO2) were reported.

TL;DR: In a joint research program the Umweltbundesamt, the commission of European Communities, the U.S. EPA and the Fraunhofer-Institute of Toxicology and Aerosol Research funded the development of a reference dust sampler in order to study the particle size distribution of ambient air aerosol and compare the results obtained with the reference dust Sampler with those of particle samplers operated in Europe and the United States.

A sampler for total suspended particulates with size resolution and high sampling efficiency for large particles
TL;DR: In this article, a Wide Range Aerosol Classifier (WRAC) was used to compare the performance of various widely used dust samplers for a field intercomparison.

Aerosols and microgravity
TL;DR: In this paper, an important advantage of aerosols as compared to liquid dispersions is the absence of surface and electric double layer effects, which makes interpretation of experiments much easier and makes it possible to study nonlinear and nonlinear processes.
