How many nanoparticles does your car emit?

Blog post by Joonas Vanhanen, CTO, Airmodus First published January 18th 2018 on LinkedIn by J. Vanhanen Topi Rönkkö, Tampere University of Technology, together with his colleagues showed that traffic is a source for small nanoparticles (link to this study further down). They call them nano cluster aerosol (NCA). The size of these particles is […]

Health effects of fine particles brought to our living rooms

Blog post by Katrianne Lehtipalo, Research Scientist at PSI.   A recent article in Science [1] featured growing evidence that air pollution, especially fine particles, could be linked, not only to lung and heart disease, but also to Alzheimer’s and dementia. This kind of findings ought to interest people also outside the readership of scientific journals. […]

On measurement of particle size distribution of sub 5 nm aerosol particles; by Joonas Vanhanen, Nano Enthusiast and Airmodus CTO

Nano particles have been sized based on their electrical mobility. This is not efficient because most of the nano particles are electrically neutral. Measuring the particle size distribution typically consist of detecting size selected particles with an aerosol particle detector such as Condensation Particle Counter (CPC). This is also the working principle of Scanning Mobility […]

Blue-sky science

This August I started as visiting scientist at the Paul Scherrer Institute in Switzerland. My project focuses on understanding how, when and why vapor molecules form clusters and aerosol particles. The project is funded by the European Comission’s Horizon 2020 programme under Marie Sklodowska Curie actions. Horizon 2020 is the EU’s biggest investment in research and […]
