  2. 1. Precision mass measurements : Final limit of SMILETRAP I and the developments of SMILETRAP II

    Author : Andreas Solders; Reinhold Schuch; Juha Äystö; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SMILETRAP; Precision mass spectrometry; Penning trap; Atomic mass; Highly charged ions; Low energy ion storage; Time of flight ion cyclotron resonance; High frequency; Proton mass; QED; g-factor; Physics; Fysik; Physics; fysik;

    Abstract : The subject of this thesis is high-precision mass-measurements performed with Penning trap mass spectrometers (PTMS). In particular it describes the SMILETRAP I PTMS and the final results obtained with it, the masses of 40Ca and that of the proton. READ MORE

  4. 2. Pressurised Fluid Extraction of Bioactive Species in Tree Barks : Analysis using Hyphenated Electrochemical Mass Spectrometric Detection

    Author : Michelle Co; Charlotta Turner; Per J.R Sjöberg; Kari Hartonen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pressurised fluid extraction; antioxidants; DPPH; water; ethanol; antioxidant activity; antioxidant capacity; electrochemial detection; mass spektrometry; Chemistry; Kemi; Analytical Chemistry; Analytisk kemi;

    Abstract : Analytical chemistry has developed throughout time to meet current needs. At present, the interest in biorefinery is growing, due to environmental awareness and the depletion of fossil resources. Biomass from agricultural and forestry industries has proven to be excellent raw material for different processes. READ MORE

  5. 3. Bioanalysis using capillary electrophoresis and mass spectrometry : Applied on proteins, protein nanofibrils and polyvinyl alcohol microbubbles

    Author : Leila Josefsson; Åsa Emmer; Ulrika Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; : amyloid; capillary electrophoresis; contrast agents; detection; human blood plasma; ionic liquids; mass spectrometry; microbubbles; polyvinyl alcohol microbubbles; protein nanofibrils; proteins; Kemi; Chemistry;

    Abstract : The sequencing of the genome of various species, including the human species, have led to increased understanding about how a protein structure is generated, and how specific structures are related to the proteins’ functionality. In paper I and II of this thesis, the folding of proteins in vitro to form hierarchical nanostructures, which in vivo often have a pathological effect, have been studied. READ MORE

  6. 4. Strategies for Miniaturized Biomarker Detection

    Author : Belinda Adler; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomarker; miniturization; lab-on-a-chip; proteomics; PSA; microarray; mass spectrometry; MALDI MS; SPE; sample preparation; immunoaffinity; antibody; aptamer; mass tag; ISET.;

    Abstract : The aim of this thesis is development and application of different miniaturized strategies for detection of biomarkers. The biomarker PSA (prostate specific antigen), which is prostate cancer specific, has been the main focus of the thesis. READ MORE

  7. 5. Weigh them all! : Cosmological searches for the neutrino mass scale and mass ordering

    Author : Sunny Vagnozzi; Katherine Freese; Lars Bergström; Alessandra Silvestri; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neutrinos; neutrino mass; neutrino mass ordering; cosmology; cosmic microwave background; large-scale structure; galaxy surveys; dark energy; cosmic inflation; data analysis; teoretisk fysik; Theoretical Physics;

    Abstract : The elusive neutrinos are among the most intriguing constituents of the particle zoo. The observation of neutrino flavour oscillations, indicating that neutrinos are massive, provides the only direct evidence for physics beyond the Standard Model. READ MORE
