    Abstract : Gas bubbles smaller than 1 micrometre in water, commonly referred to as nanobubbles, is a growing field of research and innovation. Applications range from medical imaging and drug delivery to mining industry and environmental remediation. READ MORE

  5. 23. Dispersion and Transformation of Traffic Exhaust Particles in the Urban Atmosphere

    Author : Matthias Ketzel; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; condensation; deposition; dilution; particle size distribution; plume model; street canyon; traffic pollution; urban environment; turbulence; aerosol dynamics modelling; coagulation; Physics; Fysik; Fysicumarkivet A:2004:Ketzel;

    Abstract : Ultrafine particles, their sources and fate in the atmosphere are currently key issues in atmospheric research owing to concern about their effects on human health and global climate. Traffic emissions are a dominating source of ultrafine particles, especially in urban areas. READ MORE

  6. 24. The fundamentals of ultrafine grinding in vibro-energy and annular ball mills

    Author : Osawaru A. Orumwense; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : The growing demand for ultrafine materials, the stringent quality requirements and the rising energy cost have prompted interests in the development and improvements of fine particles production techniques. The methods of producing fine particles are summarized in this thesis. READ MORE

  7. 25. Potential mechanisms for acute health effects and lung retention of inhaled particles of different origin

    Author : Anna Klepczynska Nyström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Environmental particle exposure is known to have negative health effects. There is limited knowledge about how size and origin of particles influence these effects. There is also little known regarding the fate of ultrafine particles (particles in nanosize;< 100 nanometers in diameter) after being inhaled. READ MORE
