  1. 1. Imaging mass spectrometry for in situ lipidomics: from cell structures to cardiac tissue

    Author : Sanna Sämfors; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Myocardial infarction; PC12 cells; Cell membrane; Mass spectrometry imaging; Sample preparation; Lipidomics; ToF-SIMS; Gas cluster ion beam;

    Abstract : Imaging of cells and tissues is important for studying different processes within biological systems due to the spatial information provided for different molecular species during imaging. One powerful imaging technique is mass spectrometry imaging (MSI). READ MORE

  2. 2. Electron energization in near-Earth space : Studies of kinetic scales using multi-spacecraft data

    Author : Elin Eriksson; Andris Vaivads; Masahiro Hoshino; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; magnetic reconnection; electron acceleration; electron heating; magnetosheath; magnetotail; magnetic nulls; Cluster; Magnetospheric MultiScale; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : Plasma, a gas of charged particles exhibiting collective behavior, is everywhere in the Universe. The heating of plasma to millions of degrees and acceleration of charged particles to very high energies has been observed in many astrophysical environments. How and where the heating and acceleration occur is in many cases unclear. READ MORE

  3. 3. Experimental studies of cluster ions containing water, ammonia, pyridine and bisulphate

    Author : Mauritz Johan Ryding; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : clusters; ions; water; ammonia; pyridine; bisulphate; cross sections; collision induced dissociation CID ; kinetic modelling; electrospray ionization ESI ; time-of-flight TOF ; mass spectrometry;

    Abstract : Molecular cluster ions are fascinating subjects of study. Bridging the size gap between molecules and bulk, they often display non-trivial size dependent behaviour and properties. READ MORE

  4. 4. Free Clusters Studied by Synchrotron-Based X-ray Spectroscopy: From Rare Gases to Metals

    Author : Sergey Peredkov; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supraconductors; magnetic resonance; relaxation; spectroscopy; magnetic and optical properties; rare-gas clusters; Condensed matter:electronic structure; electrical; metal clusters; photoemission; synchrotron radiation; core-level spectroscopy; Auger decay; XPS; nano-particles; free clusters; egenskaper elektriska; spektroskopi; magnetisk resonans; magnetiska och optiska ; supraledare; Kondenserade materiens egenskaper:elektronstruktur;

    Abstract : The main topic of this Thesis is the x-ray spectroscopic studies of free nano-clusters with size more than 10^3 atoms. The photoelectron spectroscopy experiments on rare gas and metal clusters were performed at beamline I411 at MAX-lab National Swedish synchrotron radiation facility. Free rare-gas clusters are simplest objects in cluster research. READ MORE

  5. 5. Towards a realistic hyperon reconstruction with PANDA at FAIR

    Author : Adeel Akram; Karin Schönning; Michael Papenbrock; Carl Nettelblad; Marek Jacewicz; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Hyperon; Extended Target; Tracking; PANDA; FAIR; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Abstract : The goal of the PANDA (anti-Proton ANnihilation at DArmstadt) experiment at FAIR (Facility for Anti-proton and Ion Research) is to study strong interactions in the confinement domain. In PANDA, a continuous beam of anti-protons () will impinge on a fixed hydrogen (p) target inside the High Energy Storage Ring (HESR), a feature intended to attain high interaction rates for various physics studies e.
