  1. 11. Electric Fields for Surface Design and Chemical Analysis

    Författare :Christian Ulrich; Fredrik Björefors; Ingemar Lundström; Tautgirdas Ruzgas; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electric fields; Surface design; Chemical analysis; Bipolar electrodes; Impedance spectroscopy; Electrochemistry; Elektrokemi; Chemical physics; Kemisk fysik; Physical chemistry; Fysikalisk kemi; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : This thesis deals with the use of electric fields for evaluation and control of chemical systems. An electric field can result in the flow of charge across an interface between a metal and a solution, by means of chemical reactions. This interplay between electricity and chemistry, i.e. LÄS MER

  3. 12. Geometrical and Electronic Structures at Molecule-Metal Interfaces from Theoretical Modeling

    Författare :Sai Duan; Yi Luo; Axel Groß; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SERS; Electrochemistry; DFT; MD; SRA - Energy; SRA - Energi;

    Sammanfattning : In this thesis, we focus on theoretical investigations on metal interfaces where many heterogeneous chemical reactions take place. Surface-enhanced Raman scattering (SERS) spectroscopy and the modern electrochemical methods are important in-situ techniques that have been widely employed for a variety of applications. LÄS MER

  4. 13. Electrochemical and Enzymatic In Vitro Studies on Reactive Drug Metabolites. Synthesis, Characterization and Avoidance

    Författare :Tove Johansson Mali´n; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cytochrome P450; Drug; Electrochemical oxidation; Electrochemistry; Intermediate; Metabolism; Metabolic activation; Mimicry; Reactive Metabolite; Trapping.;

    Sammanfattning : During development of pharmaceuticals, it is essential to as early as possible identify and preferably avoid formation of reactive metabolites and intermediates. Reactive metabolites may represent obstacles in the development and use of drugs, due to their potential toxicity. LÄS MER

  5. 14. Corrosion and Surface Studies of Stainless Steel and Chromium Carbide Thin-Films

    Författare :Jonas Högström; Leif Nyholm; Kristina Edström; Patrik Schmutz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; corrosion; electrochemistry; thin film; stainless steel; passive film; chromium carbide; carbon oxidation; surface; depth profile; XPS; SEM; EQCM; sputtering;

    Sammanfattning : Although the passive films that form on stainless steels have been extensively studied, the concentration depth profiles are not fully understood. Their thinness makes passive films hard to study, but angle-resolved X-ray photoelectron spectroscopy (ARXPS) is a non-destructive technique that can be used to obtain depth information. LÄS MER

  7. 15. Polyelectrolyte Brush Electrodes for Protein Capture and Release

    Författare :Gustav Ferrand-Drake Del Castillo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pH-responsive interfaces; Polyelectrolyte brushes; protein immobilization; electrochemistry.;

    Sammanfattning : Stimuli-responsive polyelectrolyte brushes switch as a function of pH between a charged and neutral state that affects their electrostatic interactions with other charged molecules like proteins. Adjustment of the pH results in the binding of large quantities of proteins making polyelectrolyte brushes widely used as biointerfaces. LÄS MER
