1. Mass Spectrometry with Electrospray Ionization from an Adjustable Gap
Sammanfattning : In this thesis the fabrication and analytical evaluation of two new electrospray emitters utilized for mass spectrometry analysis is presented. The emitters are based on a new concept, where the spray orifice can be varied in size. The thesis is based on two papers. All present-day nanoelectrospray emitters have fixed dimensions. LÄS MER
2. Advancing portable, aqueous drug delivery to the human lung
Sammanfattning : Lung disease profoundly impacts human health: many lung diseases are currently without cure and require continued treatment. Due to their ease of use and integration into the daily routine, portable inhalers are the preferred treatment option for patients. LÄS MER
3. Engineering Ceramics for Tribological Systems. Manufacture, Properties and Testing
Sammanfattning : A broad range of commercial and experimental grades of ceramics and ceramic composites was tested in various model tests and simplified component tests. The tests were done to establish important microstructural features, friction and wear mechanisms. LÄS MER
4. Additive Manufacturing and Integration of 3D MEMS using Ultrafast Lasers and Magnetic Assembly
Sammanfattning : The geometry of MEMS devices is limited by the technologies used to fabricate them. Today, microsystems are manufactured with patterning technologies that allow only for 2D and 2.5D geometries. LÄS MER
5. High-Temperature Microfluidics for Space Propulsion
Sammanfattning : In this thesis, microfabrication methods and tools for analysis of heated cold-gas microthrusters are presented, with the aim of improving their reliability and performance. Cold-gas thrusters operate by accelerating pressurized gas through a nozzle. LÄS MER
