1. Laser-assisted CVD Fabrication and Characterization of Carbon and Tungsten Microhelices for Microthrusters
Abstract : Laser-induced chemical vapor deposition (LCVD) is a process enabling the deposition of solid material from a gas phase in the form of free-standing microstructures with high aspect ratios. The deposition rate, wire diameter, and material properties are sensitive to changes in temperature and gas pressure. READ MORE

2. Synthesis and Characterization of Transition Metal Diborides
Abstract : This thesis is devoted towards physical vapor deposition (PVD) of thin films of transition-metal (TM) diborides, focused on the material system TiBx, Ti1-xAlxB2-y and CrBx. The metal diborides are a large family of compounds with both metallic and ceramic properties, due to its bonding nature being a mix of covalent and ionic bonds. READ MORE

3. Electron Tunneling and Field-Effect Devices in mm-Wave Circuits
Abstract : Short high-frequency electromagnetic pulses, also referred to as wavelets, are considered for use in various short-range impulse based ultra-wideband applications, such as communication, imaging, radar, spectroscopy, and localization. This thesis investigates field-effect and tunneling based semiconductor devices and their operation in millimeter-wave (mm-wave) impulse transceivers. READ MORE

4. The asthmatic airway response – effects on physiology and biomarkers
Abstract : Asthma is a common airway inflammatory disease, associated with a variable degree of airway obstruction. It is a heterogeneous condition with large variations in severity and clinical presentation. Moreover, disease activity can vary from time to time. Taken together, these factors make the diagnosis, monitoring and treatment of asthma challenging. READ MORE

5. Deposition of Al-doped ZnO films by high power impulse magnetron sputtering
Abstract : Transparent conducting oxides (TCOs) are an important class of materials with many applications such as low emissivity coatings, or transparent electrodes for photovoltaics and flat panel displays. Among the possible TCO materials, Al-doped ZnO (AZO) is studied due to its relatively low cost and abundance of the raw materials. READ MORE
