  1. 1. Engineered nanomaterials in in vivo and in vitro models

    Författare :Laura Abariute; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor nanowires; Nanoparticle exposure; Mouse exposure; Cell exposure; Nanotoxicology; Nanosafety; Fysicumarkivet A:2018:Abariute;

    Sammanfattning : Nanotechnology and engineered nanomaterials (ENM) empower existing technologies. One of the great examples are III-V semiconductor nanowires (NW), which have a broad application range. The occupational safety and hazard organizations draw attention to ENM, as their physical and chemical characteristics differ from the ones of bulk materials. LÄS MER

  3. 2. Nanoparticles: Characterization and exposure metrics

    Författare :Linus Ludvigsson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SEM; TEM; Nanoparticles; Aerosols; occupational exposure; CNTs; Fysicumarkivet A:2014:Ludvigsson;

    Sammanfattning : Exposure to aerosol nanoparticles has always been present in the evolution of humans, and thus has the human body developed ways of dealing with particles that enters the body. However with the emerging nanotech industry, new types of nanoparticles are being produced and used. LÄS MER

  4. 3. Single Copper Nanoparticle Oxidation

    Författare :Sara Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dark-field scattering spectroscopy; single particle; plasmonic nanospectroscopy; plasmonic sensing; transmission electron microscopy; oxidation; nanoscale Kirkendall effect;

    Sammanfattning : Cu nanoparticles are commonly used in microelectronic devices and as catalysts in, for example, methanol synthesis and methanol steam reforming reactions. However, Cu nanoparticles are prone to oxidation. LÄS MER

  5. 4. Development and comparison of in vitro toxicity methods for nanoparticles : Focus on lung cell exposure

    Författare :Siiri Latvala; Karine Elihn; Hanna Karlsson; Lennart Möller; Hannu Norppa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    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

  7. 5. On the exposure assessment of engineered nanoparticles in aquatic environments

    Författare :Julian A. Gallego-Urrea; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aquatic nanoparticles; exposure assessment;

    Sammanfattning : The socio-economic benefits anticipated with the use and production of nanomaterial and nanoparticles in consumer products are linked to the fulfillment of the requirement for sustainability during the whole material life cycle. Engineered nanoparticles (ENP) can be of environmental concern, both due to the possible hazardous effects but also due to the differences in properties compared to regular chemicals, e. LÄS MER
