  1. 1. An in situ spectro-electrochemical study of aluminium/polymer interfaces : development of ATR-FTIR and its integration with EIS for corrosion studies

    Författare :Maria Öhman; Christofer Leygraf; Jan-Olov Nilsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; : ATR-FTIR; EIS; spectro-electrochemical; interface; aluminium; polymer; Other chemistry; Övrig kemi;

    Sammanfattning : In order to extend the applications of aluminium, organic coatings may be applied on sheet materials, for instance for corrosion protection or aesthetic surface finish purposes in the automotive and construction industries, or on foil materials in the flexible packaging industry. The most common mechanisms for deterioration and structural failure of organically coated aluminium structures are triggered by exposures to the surrounding environment. LÄS MER

  3. 2. Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries

    Författare :Neeha Gogoi; Erik Berg; M. Rosa Palacín; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; solid electrolyte interphase; electrolyte additives; reaction mechanism; ethylene carbonate; vinylene carbonate; tris trimethylsilyl phosphate; surface enhanced Raman spectroscopy; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Lithium-ion batteries constitute a leading technology that plays a major role in the transition towards sustainable transportation and power generation. The stability of modern batteries relies on a passivation layer formed on the negative electrode known as the solid electrolyte interphase (SEI). LÄS MER

  4. 3. Labeling, tagging and charging - Long standing issues in bioenergetics addressed with novel techniques

    Författare :Tobias Gustavsson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WrbA; site specific labeling; fusion proteins; spectro electrochemistry; succinate quinone reductase; NADH quinone oxidoredictase; cytochromes; Respiratory chain;

    Sammanfattning : Understanding the molecular details of bioenergetic processes is fundamentally important. Defects in the mitochondrial energy metabolism can lead to untimely apoptosis and thus cause serious degenerative human diseases. LÄS MER

  5. 4. Development of ATR-FTIR Kretschmann Spectroscopy for In situ Studies of Metal / Polymer Interfaces : and its Intergration with EIS for Exposure to Corrosive Conditions

    Författare :Maria Öhman; Christofer Leygraf; Herman Terryn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : The environmental stability of a metal / polymer interface is essential for the durability and mechanical stability of constructions in several important areas such as the automotive, offshore, building and aerospace industries. The protective capability of a polymer film is strongly connected to its barrier properties, but the transport of water and corrosive constituents through the polymer and the subsequent processes at the metal surface are complicated to analyse in detail.
