1. Wood hydrolysates- New concepts in renewable material design
Sammanfattning : Wood hydrolysates (WHs) are biomasses obtained in processes involving hydrothermal treatments of wood. WHs are rich in hemicelluloses and lignin. Instead of complicated extraction processes, such as precipitation, or extensive purification, this work utilizes the crude WHs. LÄS MER
2. Creep Behavior of High Temperature Cast Materials for Exhaust Applications
Sammanfattning : This thesis focuses on creep of four cast materials intended for exhaust manifolds in heavy-duty truck engines. Two of the materials are ferritic ductile cast irons, SiMo51 and SiMo1000, one is an austenitic ductile cast iron, D5S, and another one is an austenitic cast steel, HK30. LÄS MER
3. Mechanical considerations in the design of high-precision surface micromachined devices
Sammanfattning : Many mechanical properties of surface micromachined devices, such as strength and elastic properties, depend on the manufacturing process and are therefore unique to the device. In order to achieve higher precision, it is essential that correct mechanical characteristics are used in the work of designing devices. LÄS MER
4. Mechanical Properties of Semi-Solid Al Castings : Role of Stirring
Sammanfattning : Semi-solid metal (SSM) casting has been widely used in automotive industries to reduce the weight. In RheoMetalTM process which is one of the variations of SSM, the slurry fabrication can be finished within 30 second and can the slurry making process can be integrated into a high pressure die casting (HPDC) route without significant adjustments, making the process a promising alternative for industrial application.

5. A study of wood adhesion and interactions using DMTA
Sammanfattning : The aim of the work presented in this thesis was to investigate whether the adhesion of glues and lacquers to wood could be studied using dynamic mechanical thermal analysis (DMTA). This method has been widely used to study interactions in polymer blends, copolymers and in polymeric composites but very few investigations had been done on solid wood. LÄS MER
