  1. 1. Stability of Bulk-heterojunction blends for Solar Cell Applications

    Författare :Camilla Lindqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanostructure; PCBM crystallisation; bulk-heterojunction; Polymer solar cells; stability;

    Sammanfattning : Polymer solar cells are a promising alternative to more traditional silicon solar cells. This is mainly due to the good solubility of organic semiconductors, which makes it possible to produce large-scale and mechanically flexible devices with roll-to-roll processes. LÄS MER

  3. 2. Facilitating the Implementation of Smart Maintenance

    Författare :Camilla Lundgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industry 4.0; innovation; maintenance; manufacturing; digitalisation;

    Sammanfattning : Innovations and rapid advancements in digital technologies in the manufacturing industry are setting high expectations of highly automated, intelligent and interconnected production systems. To bring these expectations to realisation and secure productive and sustainable production systems, maintenance organisations must develop accordingly. LÄS MER

  4. 3. Predicting the Long-Term Insulation Performance of District Heating Pipes

    Författare :Camilla Persson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat conduction; polyurethane foam; insulation capacity; diffusion; thermal conductivity; cyclopentane; solubility coefficient; long-term performance;

    Sammanfattning : The aim of the studies that comprise this thesis was to predict the heat loss over timefrom a range of district heating pipes insulated with closed-cells foam. The thermalconductivity of the foam changes over time when it is not diffusion-tight encapsulatedagainst the environment, as diffusion alters the cell gas composition until it reachesequilibrium with the surrounding air.

  5. 4. Site-Dependent Effects in High-Accuracy Applications of GNSS

    Författare :Camilla Granström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Global Navigation Satellite Systems, GNSS are used in many applications demanding millimetre-level accuracy in positioning. Such applications include monitoring of crustal movements. The GNSS technique also facilitates estimates of the tropospheric water vapour content, an important parameter in numerical weather predictions and climate research. LÄS MER
