Scientists from the Institute of Chemical Process Fundamentals of the CAS (ICPF) established a Czech-French research collaboration with colleagues from IMT Lille Douai within the Barrande mobility project.
Within the project entitled Hygroscopicity of atmospheric aerosol (id: 8J21FR025), the first visit of French colleagues to the aerosol laboratory at ICPF is currently underway in order to conduct laboratory experiments on the hygroscopic properties of aerosol particles formed during ozonolysis of terpenes or cyclohexene. The hygroscopicity of particles in the atmosphere is associated, for example, with cloud formation and hence with effects on climate. The experiments are carried out in a Teflon reaction chamber and monitored by an extensive set of measuring instruments provided by both collaborating laboratories.
The project combines the expertise of the scientists of the ICPF Prague and IMT Lille Douai using state-of-the-art measurement techniques for aerosol and gas phase analysis. The main output of the project will be an extension of the knowledge on the influence of biogenic and/or anthropogenic substances in the atmosphere on the hygroscopicity of aerosols, summarised in a scientific publication.
