1. Synthesis of carbon-covered iron nanoparticles by photolysis of ferrocene
Sammanfattning : One important driving force in nanotechnology today is the change which can be made in the properties of a material when the dimensions of its individual building blocks are decreased below approximately 100 nm. Such small building blocks, typically nanoparticles, may induce new and unique properties compared to those of the corresponding bulk material. LÄS MER
2. Development and comparison of in vitro toxicity methods for nanoparticles : Focus on lung cell exposure
Sammanfattning : Concerns for the toxic effects of airborne nanoparticles have been raised along with the increasing production of nanostructured materials. However, the health risks of nanoparticle exposure are currently not fully understood. The most commonly used techniques to study nanoparticle toxicity, both in vivo and in vitro, have several limitations. LÄS MER
3. Measuring Elemental Carbon in Occupational Environments
Sammanfattning : Carbonaceous aerosol particles from combustion, such as diesel exhaust particles (DEP), harm human health and affect the Earth’s radiative system.Elemental carbon (EC) has been proposed to be used as a marker of DEP. LÄS MER
