21. Assessment of novel applications for nano-porous thermal insulation in district heating pipes and building walls
Abstract : In nano-porous thermal insulation there is a strong relation between the pressure and the thermal conductivity, even at pressures close to atmospheric pressure. This thesis presents research on applications of nano-porous insulation in hybrid insulation district heating pipes and in building walls. READ MORE

22. Insulation materials in district heating pipes : Environmental and thermal performance of polyethylene terephthalate and polyurethane foam
Abstract : District heating can contribute to increased energy efficiency in society. The environmental impact can be reduced by minimising the heat losses in the district heating pipes during distribution of the heat to the customers. READ MORE

23. Characterization of Nanomaterials for Interconnect and Thermal Management in Electronic Packaging
Abstract : Electronic packaging, protecting the fragile chip from atmosphere and providing the paths for signal transmission as well as heat dissipation, is one of the most important parts in electronic devices. The cost, dimensions, performance, and reliability of an electronic device therefore strongly depend on its packaging structures and materials. READ MORE

24. Studies on the thermal degradation of thermosetting polyimides and their composites
Abstract : The thesis contains a background and reflections section, an introduction, and three appended articles. The first section is reserved for some of the background and basics on polymers and polymer composites and a discussion on their effect on our everyday lives. The introduction gives a brief recap of the project. READ MORE

25. Development of a non-destructive testing method for thermal assessment of a district heating network
Abstract : This thesis presents the development of a non-destructive testing (NDT)method for thermal assessment of pre-insulated district heating (DH) pipes with high accuracy, in which the development process from literature review to its present stage is presented and discussed. Pre-insulated DH pipes have been in use for more than 40 years. READ MORE
