  2. 16. New single particle methods for detection and characterization of nanoparticles in environmental samples

    Author : Jani Tuoriniemi; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Detection; Quantification; Metrology; Trace particle;

    Abstract : Nanoparticles (NP) are being used in rapidly increasing quantities which has resulted in concerns about possible harmful effects for health and environment. NP are already undergoing similar risk assessment programs as conventional chemicals, and due to their enhanced surface reactivities it has been proposed that the use of NP should be regulated by specific legislation based on particle size.

  4. 17. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines

    Author : Zhenkan Wang; Förbränningsfysik; []
    Keywords : Combustion diagnostics; Laser induced fluorescence LIF ; Ultra-high-speed; Burst-mode laser; Ballistic imaging; Particle imaging velocimetry; Laser Doppler anemometry; Turbulent premixed combustion; Plasma; Internal combustion engine; Partially premixed combustion PPC ; Auto-ignition; OH radical; CH2O formaldehyde ; Fysicumarkivet A:2018:Wang;

    Abstract : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. READ MORE

  5. 18. On Weapons Plutonium in the Arctic Environment (Thule, Greenland)

    Author : Mats Eriksson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear physics; Kärnfysik; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; Nuclear engineering and technology; Kärnteknik; realtime digital image systems; SEM; ICP-MS; alpha spectrometry; gamma spectrometry; heterogeneous activity concentration; hot particle; separation technique; isotopic ratio; inventory; source term; fallout; americium; uranium; plutonium; radionuclide; Bylot Sound; Greenland; Thule; environmental radioactivity; nuclear accident;

    Abstract : This thesis concerns a nuclear accident that occurred in the Thule (Pituffik) area, NW Greenland in 1968, called the Thule accident. Results are based on different analytical techniques, i.e. gamma spectrometry, alpha spectrometry, ICP-MS, SEM with EDX and different sediment models, i. READ MORE

  6. 19. Miniaturized localized surface plasmon resonance biosensors

    Author : Si Chen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colloidal lithography; Surface plasmon resonance; biosensing; electron beam lithography; single molecule; hyperspectral imaging; photo functionalization;

    Abstract : Abstract Reliable and sensitive biosensors are required for fast and accurate diagnostics. Localized surface plasmon resonances (LSPRs) in noble-metal nanoparticles possess very high refractive index sensitivity close to the metal surface and therefore constitute an attractive biosensing platform.

  7. 20. Direct observation of biomolecule adsorption and spatial distribution of functional groups in chromatographic adsorbent particles

    Author : Anders Ljunglöf; Abraham Lenhoff; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Confocal microscopy; confocal Raman spectroscopy; protein adsorption; ligand distribution; visualization; imaging; Bioteknik; Bioengineering; Bioteknik; Surface Biotechnology; ytbioteknik;

    Abstract : Confocal microscopy has been used as a tool for studying adsorption of biomolecules to individual chromatographic adsorbent particles. By coupling a fluorescent dye to protein molecules, their penetration into single adsorbent particles could be observed visually at different times during batch uptake. READ MORE
