    Sammanfattning : Clusters/nanoparticles are aggregates of a “small” number of building blocks, atoms or molecules, ranging from two up to millions of atoms. Two main groups of clusters have been studied using photoelectron spectroscopy based on synchrotron radiation. LÄS MER

  3. 3. Toxicity and biological impact of metal and metal oxide nanoparticles Focus on the vascular toxicity of ultra-small titanium dioxide nanoparticles

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Narges Bayat; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Nanotoxicology; Ultra-small nanoparticles; biokemi; Biochemistry;

    Sammanfattning : The application of nanoparticles (NPs) in different technologies has led to tremendous advancement in those fields.  Moreover, there is growing interest in application of ultra-small NPs (USNPs) at 1-3 nm due to their distinct molecule like features. Parallel to these promises, there is a growing concern regarding their safety. LÄS MER

  4. 4. Nanoplasmonic Sensing using Metal Nanoparticles

    Sammanfattning : In our modern society, we are surrounded by numerous sensors, constantly feeding us information about our physical environment. From small, wearable sensors that monitor our physiological status to large satellites orbiting around the earth, detecting global changes. LÄS MER

  5. 5. Nanoparticles: Characterization and exposure metrics

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Linus Ludvigsson; [2014]
    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
