  1. 1. Biomimetic surfaces : Preparation, characterization and application

    Författare :Annika Borgh; Bo Liedberg; Fredrik Höök; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Self-assembled monolayers; biomimetic surfaces; phosphates; antifreeze; surface spectroscopy; Molecular physics; Molekylfysik;

    Sammanfattning : I denna avhandling beskrivs tillverkning, karaktärisering och tillämpning av ett antal biomimetiska ytor. Biomimetik är att härma naturen och grundtanken är att titta på hur naturen löst liknande problemställningar. LÄS MER

  3. 2. Water-Metal Surfaces : Insights from core-level spectroscopy and density functional theory

    Författare :Theanne Schiros; Anders Nilsson; John Hemminger; Stockholms universitet; []
    Nyckelord :water; hydroxyl; metal; surfaces; x-ray spectroscopy; density functional theory; bonding; fuel cell; kemisk fysik; Chemical Physics;

    Sammanfattning : Computational methods are combined with synchrotron-based techniques to analyze the structure and bonding of water and water plus hydroxyl at metal surfaces under UHV and at near-ambient conditions. Water-metal interaction plays a crucial role in a multitude of cosmic, atmospheric and biological phenomena as well as heterogeneous catalysis, electrochemistry and corrosion. LÄS MER

  4. 3. Tunable surfaces : using polyoxoniobates and -tantalates as molecular building blocks

    Författare :Mark Rambaran; C. André Ohlin; Jean-Francois Boily; Mari-Ann Einarsrud; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes and explains the use of aqueous polyoxometalates (POMs), as molecular building blocks in the fabrication of tunable solid-state materials, such as thin films.  Microwave irradiation in the synthesis of Nb10, Nb6 and Ta6 is a rapid and efficient alternative to conventional hydrothermal methods, while offering equal – if not greater yields – of product.
