  1. 21. Acoustic manipulation for cell and spheroid cellomics

    Författare :Karl Olofsson; Martin Viklund; Maria Tenje; KTH; []
    Nyckelord :Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Ultrasonic standing wave (USW) particle manipulation has during the last two decades matured into a valuable tool to combine with microfluidics. Acoustophoresis, migration through sound, is the result of the acoustic radiation force acting on particles suspended in an acoustic field.

  3. 22. Insights into Electrochemical Energy Storage by use of Nanostructured Electrodes

    Författare :David Rehnlund; Leif Nyholm; Kristina Edström; Fredrik Björefors; Emanuel Peled; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot oorganisk kemi; Chemistry with specialization in Inorganic Chemistry;

    Sammanfattning : Template-assisted electrodeposition is a powerful technique for fabricating complex nanostructured electrodes. Through the use of pulsed-electrodeposition nanostructured electrodes of Al, Cu and Sn have been realised and subsequently coated electrochemically with V2O5, MnxO, Li, Cu2O and a polymer electrolyte.

  4. 23. A search for solar dark matter with the IceCube neutrino telescope

    Författare :Gustav Wikström; Klas Hultqvist; John Carr; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; neutrinos; neutrino telescopes; IceCube; Astroparticle physics; Astropartikelfysik; fysik; Physics;

    Sammanfattning : Dark matter particles in the form of supersymmetric Weakly Interacting Massive Particles (WIMPs) could accumulate in the centre of the Sun because of gravitational trapping. Pair-wise annihilations of WIMPs could create standard model particles out of which neutrinos could reach the Earth. LÄS MER

  5. 24. Moiré Exciton Landscape and its Optical Properties in Two-Dimensional Semiconductors

    Författare :Joakim Hagel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; moiré physics; excitons; 2D materials;

    Sammanfattning : In recent years the emergence of atomically thin nanomaterials has led to a new research venue, revealing intriguing properties making them an excellent platform to study many-particle quantum phenomena. Of particular interest is the class of nanomaterials called transition metal dichalcogenides (TMDs), where the strong light-matter coupling reveals promising opportunities in the pursuit of novel optoelectronical devices.

  7. 25. Molecular-Level Investigations of Water-Organic Systems of Atmospheric Relevance

    Författare :Sofia M. Johansson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EMB method; desorption kinetics; water uptake; organic surfaces;

    Sammanfattning : It is known that aerosol particles may have warming and/or cooling effects on the climate and negative health effects that depend on their chemical and physical properties. However, current understanding of atmospheric particles’ effects is poor due to the diversity of their constituents and associated variations in properties. LÄS MER
