Traffic-related emissions result from either the combustion process in vehicle engines or from the tyre contact with the pavement. The latter produces street dust, which is problematic during the spring in the Nordic countries.
The FINE Particles - Technology, Environment and Health – National Technology Programme has played a key role in catalysing the study of traffic-related particles in Finland, and in pushing forward public discussion on these types of emissions and their effects on urban air quality, people´s health, and atmospheric processes.
The FINE projects focused on studying the formation, characteristics, and dispersion of particles emitted by the vehicles, and the effect of different technologies. A mobile laboratory known as the “Sniffer” developed in one of the FINE projects, was used for vehicle chase measurements.
Promising results in engine technology
The technology oriented projects devoted to the potential of modern engine technology to reduce particle formation. Injection timing, combustion chamber shape, swirl motion, and controllable valve timing were found to be promising ways of cutting particulate emissions.
Finnish companies have benefited directly in terms of enhanced expertise and the improved understanding of the processes and mechanisms associated with particle formation and properties.
The FINE Programme has highlighted the need for further research in areas such as, biofuels and the characteristics of the particulates they release.
In Europe and in the USA, tougher traffic-related emission limits can be expected in the near future. New emission limits represent a major challenge in terms of developing the best technology to meet them and the best technology for providing measurement data. However, tougher limits will create new business opportunities for companies devoted to reduce emissions and develop technology suitable for combating them.
The FINE Programme launched in 2002 by Tekes, the Finnish Funding Agency for Technology and Innovation, was completed in the spring of 2006. The Programme involved over 50 individual projects and close to 60 companies and over 20 research institutions. Work of 11 FINE projects focused on traffic-related particulate emissions.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
