1. Using Light to Probe Surface Electrochemical Processes
Abstract : This thesis shows how various light-based in situ techniques can be used to follow different surface electrochemical processes such as electrochemical deposition into Nanoporous Anodic Aluminium Oxide (NP-AAO) templates and the surface structure of electrodes. Techniques based on both x-rays and visible light were used to follow surface structures and compositions, in situ. READ MORE

2. Fundamental in-situ and ex-situ studies of energy storage related materials including different applications of voltammetry
Abstract : This thesis is a summary and discussion of eight papers dealing with failures and structural aspects of Ni-Cd industrial pocket plate batteries, applications of voltammetry in adsorption studies on goethite (a-FeOOH) surfaces and synthesis and characterisation of nanostructured carbons. The work consists of different areas of chemistry; electrochemistry, structural chemistry and solution chemistry. READ MORE

3. In-situ TEM Probing of Nanomaterials
Abstract : Nanomaterials because of their small size, may have special properties unlikely to be seen in ordinary types of materials. Nanomaterials like nanotubes,nanowires and nanoparticles are best studied at the nanoscale, vital but also problematic. READ MORE

4. Mechanistic studies of localized corrosion of Al alloys by high resolution in-situ and ex-situ probing techniques
Abstract : A multi-analytical approach based on in-situ and ex-situ local probing techniques was employed to investigate localized corrosion mechanisms of some aluminum alloys in chloride containing solutions, focusing on the influence of intermetallic particles (IMPs) in the alloys. In the EN AW-3003 alloy, SEM-EDS analysis revealed constituent and dispersoid IMPs. READ MORE

5. Understanding corrosion protection mechanisms of nanocomposite polymer coatings on carbon steel : A combination of in-situ AFM and electrochemical studies
Abstract : Corrosion protection of carbon steel is crucial in today’s world and there is an urgent need to replace the hazardous compounds used with environmentally friendly anticorrosion coatings. In this European collaborative research project, new types of functional composite anticorrosion coatings for steel were developed with properties beyond the state-of-the-art using nanotechnology.
