1. Energy Efficient Air Quality Solutions for Vehicle Cabins
Sammanfattning : Maintaining a good air quality level is essential for reducing potential health risks for human beings. Vehicle cabin is one common environment where people spend increasing amount of time in modern societies. It’s an environment challenged by elevated pollutants from surrounding traffics, especially small particles like PM2. LÄS MER
2. Oxidation kinetics of nickel particles
Sammanfattning : Nanoparticles have an immense surface to volume ratio. This is a key factor to the new properties of some materials made up of such particles. The oxide layer formed on all materials will have a large influence on the behaviour of these materials. The layer isadvantageous in some cases but causes problems in other. LÄS MER
3. Be Aware of the Indoor Air. Physicochemical Characterization of Airborne Fine Particles in Occupied Homes : Physicochemical Characterization of Airborne Fine Particles in Occupied Homes
Sammanfattning : Negative health effects of exposure to particles of outdoor origin have been confirmed by epidemiological studies. In developed countries, we spend on average 65% of our time in our homes. Thus, the properties of airborne particles indoors need to be understood. LÄS MER
4. Ultrafine Particles in the Indoor Environment: Field and Laboratory Measurements
Sammanfattning : Clean air is one of the most fundamental human needs since poor air quality affects the health and the environment. It has been shown that people spend on average over 85 % of their time at work, home, school etc. Therefore, human exposure to air pollution may occur mostly indoors. Despite this fact, outdoor air pollution is also important. LÄS MER
5. Ultrafine Particles in Indoor Air. Measurements and modelling
Sammanfattning : Clean air is one of the most fundamental human needs. Since people spen on average over 85% of their time indoors at work, home, school etc., human exposure to air pollution may mostly occur indoors. LÄS MER
