  1. 1. Biomolecular interactions at model interfaces : a self-assembled monolayer approach

    Författare :Sofia Svedhem; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The overall aim of this thesis has been to explore the use of self-assembled monolayers (SAMs) in model studies of biomolecular binding at interfaces. Molecular details of interfaces are difficult to address experimentally, and in spite of the fact that interactions in the living system commonly occur at interfaces, e.g. LÄS MER

  3. 2. Phthalocyanine interfaces : the monolayer region

    Författare :Pål Palmgren; Mats Göthelid; Mats Fahlman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phthalocyanine; III-V semiconductor; transition metal oxides; adsorption; self-assembly; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : Organic molecules adsorbed on inorganic substrates are the topics of interest in this thesis. Interfaces of this kind are found in dye sensitized solar cells that convert solar energy to electricity, a promising environmentally friendly energy source which might provide a route to replace fossil fuels.

  4. 3. Molecular studies of initial atmospheric corrosion of copper : Exploration of ultra-sensitive techniques for the inhibiting effect of self assembled monolayers, and the effect of gamma radiation

    Författare :Saman Hosseinpour; Christofer Leygraf; Franz Geiger; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion; copper; self assembled monolayer; sum frequency spectroscopy; qcm; gamma radiation;

    Sammanfattning : Atmospheric corrosion indoors is of great practical importance for the degradation of metals, for example in electronics, military equipment, and cultural heritage items. It involves a wide range of chemical, electrochemical, and physical processes occurring in gas, liquid, and solid phases, and at the interfaces between them. LÄS MER

    Sammanfattning : Self-assembled monolayers (SAMs) provide well-defined and ordered films of molecules spontaneously chemisorbed on a surface. By designing molecules with desired functionalities, such molecular film can be interesting for a range of applications from molecular electronics to catalysis. LÄS MER

  7. 5. Nanometer Scale Protein Templates for Bionanotechnology Applications

    Författare :Jonas Rundqvist; David B. Haviland; Michael Grunze; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; bionanotechnology; nanobiotechnology; electron beam lithography; EBL; poly ethylene glycol ; PEG; self-assembled monolayer; SAM; self-immobilization; protein pattern; Physics; Fysik;

    Sammanfattning : Nanofabrication techniques were used to manufacture nanometer scale protein templates. The fabrication approach employs electron beam lithography (EBL) patterning on poly(ethylene glycol) (PEG) thiol (CH3O(CH2CH2O)17NHCO(CH2)2SH) self-assembled monolayers (SAM) on Au. LÄS MER
