  1. 1. The Role of Molecular Heterogeneity in the Structural Dynamics of Aqueous Solutions

    Författare :Sharon Berkowicz; Fivos Perakis; Anders Hedqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; kemisk fysik; Chemical Physics;

    Sammanfattning : Aqueous solutions constitute the basis of life, yet their complex and anomalous nature is far from well-understood. Transient molecular ordering gives rise to microscopic spatial liquid heterogeneities and fluctuations which are believed to play a key role in biochemical processes as well as in pure water, the latter of which could fundamentally alter our view on water as life's solvent.

  3. 2. The Role of Molecular Heterogeneity in the Structural Dynamics of Aqueous Solutions

    Författare :Sharon Berkowicz; Fivos Perakis; Giulio Monaco; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Water; Aqueous solutions; X-ray scattering; X-ray photon correlation spectroscopy; Dynamic light scattering; kemisk fysik; Chemical Physics;

    Sammanfattning : The liquid-liquid critical point hypothesis suggests that liquid water exists in two liquid states with different local structures, so-called high- and low-density liquid (HDL, LDL). At ambient pressure water locally fluctuates between these two states, with the fluctuations becoming more pronounced as the liquid is supercooled. LÄS MER

  4. 3. Final-State-Resolved Mutual Neutralization of Li+ and H-

    Författare :Alice F. Schmidt-May; Henning T. Schmidt; Fivos Perakis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DESIREE; ion; mutual neutralization; collision; lithium; hydrogen; Physics; fysik;

    Sammanfattning : We studied the mutual neutralization of Li+ and H- at effective collision energies of a few hundred meV, which corresponds to temperatures of around 2000 K, in the double ion storage ring DESIREE.We present a new approach to match beam velocities and a new general analysis method for non-fragmenting mutual neutralization at DESIREE.
