11. Electric Fields for Surface Design and Chemical Analysis
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
12. Geometrical and Electronic Structures at Molecule-Metal Interfaces from Theoretical Modeling
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
13. Electrochemical and Enzymatic In Vitro Studies on Reactive Drug Metabolites. Synthesis, Characterization and Avoidance
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
14. Corrosion and Surface Studies of Stainless Steel and Chromium Carbide Thin-Films
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
15. Polyelectrolyte Brush Electrodes for Protein Capture and Release
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
