  1. 6. On the phase-space distribution of heavy particles in turbulence

    Författare :Jan Meibohm; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fluid dynamics; Particle-laden flows; Turbulent aerosols; Chaotic dynamics; Non-equilibrium statistical physics;

    Sammanfattning : Turbulent fluids laden with small, heavy particles are common in nature. Prominent examples of such turbulent suspensions are water droplets in warm clouds, as well as particulate matter or living organisms in the turbulent upper layer of oceans. LÄS MER

  2. 7. Structure and dynamics of complex materials in the water-poor regime

    Författare :Sanna Gustavsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydration; cellulose; dissolution; sugar surfactant; hydrated crystals; structure; dynamics; phase diagram; fuel cell; pulsed-field-gradient PFG spin-echo NMR; Polarization Transfer solid state NMR; PXRD; GVS; TGA; amphiphilic;

    Sammanfattning : In the solid state, molecules are normally ordered in a specific structure. With time, and as a result of influence from the surroundings, solid materials can change their molecular and/or crystal structure and, as a consequence, obtain completely different properties. Water is particularly important in this respect. LÄS MER

  3. 8. Fundamental interactions in transition metal reactions

    Författare :Michael R. Coates; Michael Odelius; Markus Kowalewski; Abhik Ghosh; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum chemistry; electronic structure; multiconfigurational; density functional theory; molecular dynamics; excited state molecular dynamics; non-adiabatic dynamics; solvation; organometallic complexes; x-ray absorption spectroscopy; photoelectron spectroscopy; time-resolved spectroscopy; femtosecond; picosecond; kemisk fysik; Chemical Physics;

    Sammanfattning : Transition metal complexes that participate in homogeneous reactions often perform the role of a catalyst, facilitating novel reaction pathways. When these complexes are pushed away from their equilibrium, the arrangement of the coordinating ligands around the metal center is perturbed and new reaction pathways are opened. LÄS MER

  4. 9. Ultrafast, Non-Equilibrium Electron Transfer Reactions of Molecular Complexes in Solution

    Författare :Jonas Petersson; Leif Hammarström; Antonín Vlček; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron transfer; laser; spectroscopy; transient absorption; anisortopy; inter ligand electron transfer; dye sensitized solar cell; DSSC; vibrational relaxation; ultrafast dynamics; fs spectroscopy; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

    Sammanfattning : Photoinduced electron transfer is a fundamentally interesting process; it occurs everywhere in the natural world. Studies on electron transfer shed light on questions about the interaction between molecules and how the dynamics of these can be utilized to steer the electron transfer processes to achieve a desired goal.
