6. Fabrication and Applications of a Focused Ion Beam Based Nanocontact Platform for Electrical Characterization of Molecules and Particles
Sammanfattning : The development of new materials with novel properties plays an important role in improving our lives and welfare. Research in Nanotechnology can provide e.g. cheaper and smarter materials in applications such as energy storage and sensors. LÄS MER
7. Development and application of advanced electron microscopy techniques for materials in biological systems
Sammanfattning : Theoretically, electron microscopy and scanning probe microscopy offer information on a scale beyond the optical microscope. However, the quality of the micrograph and the obtained information is limited by the sample preparation. LÄS MER
8. An Electron Microscopy Study on Materials in Electronic Packaging
Sammanfattning : This thesis is concerned with an investigation of the microstructure on materials in electronic packaging. The materials include Ag-filled conductive adhesives, Sn-Ag-based lead free solders and metal-oxide semiconductors. LÄS MER
9. Quantitative microscopy of coating uniformity
Sammanfattning : Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer.

10. Quantitative studies of changes in microstructure and activity during ageing of supported catalysts
Sammanfattning : Catalytic converters have substantially contributed to the improvement of air quality in populated areas in the last decades by abatement of the emission of hazardous componentssuch as CO, unburned hydrocarbons and NOx. However, due to the exposure to high temperature and different components in the exhaust gas, the performance of the catalysts degrades with time. LÄS MER
