  1. 1. Precipitating Amine Absorption Systems for Carbon Capture

    Författare :Hanna Karlsson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; Non-aqueous; AMP; Solubility; Heat of absorption;

    Sammanfattning : Carbon capture using amine-based absorption is an established technology for the separation of gaseous CO2. It is used in the upgrading of gaseous fuels, and it has also been suggested that it could play a crucial role in the mitigation of climate change through post-combustion carbon capture and sequestration (CCS), and by creating carbon sinks through bioenergy CCS.

  3. 2. Innovation for tackling grand challenges : Cleantech industry dynamics and regional context

    Författare :Hanna Martin; CIRCLE; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic geography; regional innovation systems; regional innovation policy; regional path development; innovation system failures; socio-technical transitions; grand challenges; cleantech; Transformative change; Sweden;

    Sammanfattning : Grand challenges such as climate change put focus away from innovations and innovation policy as engines of economic growth towards fulfilling societal goals and sighting sustainable development. The literature on the geography of innovation has provided valuable insights on innovation activities of firms and industries and how they are positively influenced by co-location. LÄS MER

  4. 3. X-ray Phase Contrast Tomography : Setup and Scintillator Development

    Författare :Hanna Dierks; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-rays; x-ray imaging; x-ray microscopy; X-ray detectors; perovskites; laboratory setups; phase contrast; μCT; scintillator; Phase contrast PC ; Tomography x-ray computed ;

    Sammanfattning : X-ray microscopy and micro-tomography (μCT) are valuable non-destructive examination methods in many disciplines such as bio-medical research, archaeometry, material science and paleontology. Besides being implemented at synchrotrons radiation sources, laboratory setups using an X-ray tube and high-resolution scintillation detector routinely provide information on the micrometre scale.

  5. 4. Evolution of sex chromosomes in Sylvioidea songbirds

    Författare :Hanna Sigeman; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sex chromosome; neo-sex chromosome; Birds; vertebrates; Genomics; Bioinformatics;

    Sammanfattning : Sex chromosomes were discovered more than 100 years ago. They have been studied intensely from a theoretical perspective since then, giving rise to a large body of testable predictions about their evolution from autosomes. LÄS MER

  7. 5. Acute Pancreatitis. Biomarkers and radiology assessment

    Författare :Hanna Sternby; Kirurgi; []
    Nyckelord :acute pancreatitis; severity grade; Biomarkers; morphology; classification; radiology assessment; Acute pancreatitis; severity grade; Biomarkers; morphology; classification; radiology assessment;

    Sammanfattning : Background: Acute pancreatitis (AP) is a common and potentially severe disease. Early identification of severity grade is crucial for the outcome of the patient. For study approaches and comparison of inter-institutional data the AP patients need to be uniformly classified. LÄS MER
