6. Surface Characterisation Using ToF-SIMS, AES and XPS of Silane Films and Organic Coatings Deposited on Metal Substrates
Abstract : This work focuses on the surface and interfacial characterisation of silane films of a non-organofunctional silane, 1,2-bis(triethoxysilyl)ethane (BTSE), and an organofunctional silane, γ-mercaptopropyltrimethoxysilane (γ-MPS), deposited on Al, Zn and Al-43.4Zn-1.6Si (AlZn) alloy coated steel.

7. Interrogation of drug effects on the lipid composition of single cells and Drosophila brain using ToF-SIMS imaging
Abstract : Lipids are essential for all living organisms on Earth. The most important function of lipids is that they act as the building blocks of cellular membranes. Lipids consist of polar head groups and non-polar tail groups and assemble into bilayer structures to create cell and organelle membranes. READ MORE

8. Imaging mass spectrometry for in situ lipidomics: from cell structures to cardiac tissue
Abstract : Imaging of cells and tissues is important for studying different processes within biological systems due to the spatial information provided for different molecular species during imaging. One powerful imaging technique is mass spectrometry imaging (MSI). READ MORE

9. Imaging of lipids and proteins in Alzheimer's disease using Time-of-Flight Secondary Ion Mass Spectrometry
Abstract : Alzheimer’s disease (AD) is a neurodegenerative disease characterized by the formation of senile plaques. These plaques, which consist of aggregations of a peptide called amyloid-β, are deposited in-between the nerve cells in the brain, where they disrupt the signaling processes. READ MORE

10. Methods for evaluation of early bone healing at titanium implants
Abstract : Titanium has for a long time been the implant material of choice when in need for abilities as strength, biocompatibility and stability. Although numbers of studies have been made, little is known about the early events in implant healing. The primary aim in this thesis was to develop methods for evaluating bone healing around implants. READ MORE
