1. Silicon nanowire based devices for More than Moore Applications
Sammanfattning : Silicon nanowires (SiNW) are in the spotlight for a few years in the research community as a good candidate for biosensing applications. This is attributed to their small dimensions in nanometer scale that offers high sensitivity, label-free detection and at the same time utilizing small amount of sample. LÄS MER
2. Fatigue of steel bridges : New structural details and the implementation of high strength steel
Sammanfattning : The use of high strength steel has the potential to reduce the amount of steel used in bridge structures and thereby facilitate a more sustainable construction. The amount of steel and what steel grade that can be used in bridge structures and other cyclic loaded structures are often limited by a material degradation process called fatigue. LÄS MER
3. DFT calculations of initial localized corrosion of aluminum : Influence of aqueous ad-layer, chloride ions, and intermetallic particles
Sammanfattning : Localized corrosion of aluminum (Al, here including Al alloys) involves a series of physico-chemical processes at the interface between the metal and the aqueous ad-layer or the aqueous solution. The mechanisms that govern localized corrosion are quite complex and have been the subject of many experimental studies. LÄS MER
4. Processability of Laser Powder Bed Fusion of Alloy 247LC : Influence of process parameters on microstructure and defects
Sammanfattning : This thesis is about laser powder bed fusion (L-PBF) of the nickel-based superalloy: Alloy 247LC. Alloy 247LC is used mainly in gas turbine blades and processing the blades with L-PBF confers performance advantage over the blades manufactured with conventional methods. LÄS MER
5. Machining of wood : cutting data and its effect on the work environment and surface quality
Sammanfattning : Machining using circular tools is very frequent in the wood manufacturing industry. Such machinery is very efficient but also leads to problems, for example in the indoor factory environment, in the form of unhealthy wood dust emissions. Another example is imperfections in wood products such as unacceptable surface quality. LÄS MER
