1. Fundamental in-situ and ex-situ studies of energy storage related materials including different applications of voltammetry
Sammanfattning : 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. LÄS MER
2. Phase transformation and surface chemistry of secondary iron minerals formed from acid mine drainage
Sammanfattning : The mining of sulphidic ore to extract metals such as zinc and copper produces huge quantities of waste material. The weathering and oxidation of the waste produces what is commonly known as Acid Mine Drainage (AMD), a dilute sulphuric acid rich in Fe(II) and heavy metals. LÄS MER
3. Processes of Magma-crust Interaction : Insights from Geochemistry and Experimental Petrology
Sammanfattning : This work focuses on crustal interaction in magmatic systems, drawing on experimental petrology and elemental and isotope geochemistry. Various magma-chamber processes such as magma-mixing, fractional crystallisation and magma-crust interaction are explored throughout the papers comprising the thesis. LÄS MER

5. Nuclear Structure Studies near 208Pb and γ-ray Imaging Techniques
Sammanfattning : This thesis focuses on a high-resolution γ-ray spectroscopy experiment where the fragmenta- tion of a 208 Pb primary beam was used to populate even-mass nuclei around 208 Pb. It was conducted in 2012 using the Advanced GAmma-ray Tracking Array (AGATA) while it was placed at GSI Darmstadt, Germany. LÄS MER
