The construction sector is responsible for high energy consumption and large emissions of carbon dioxide, which is strongly linked to building materials. Within the European Union, the construction sector generates more than a third of all waste and circular economy is considered as a suitable approach to tackle these challenges. Furthermore, the need for renewable energy sources has increased, wi
In this thesis, a high-repetition-rate attosecond light source based on high-order harmonic generation in gases was used to perform time-resolved electron spectroscopy in atoms and solids. The source was driven by few-cycle near-infrared laser pulses with a controllable carrier-to-envelope phase, enabling the generation of sequences of two to four attosecond pulses in the extreme ultraviolet range
Within the framework Solar Heating and Cooling Programme of the International Energy Agency Task 51 “Solar Energy in Urban Planning”, case studies from Norway, Sweden, and Denmark were collected and analyzed through a comparative approach. The cases were first classified based on their urban characterization (existing and new urban areas) and then compared within the same country or in a cross-cou
Axially heterostructured nanowires are a promising platform for next generation electronic and optoelectronic devices. Reports based on theoretical modeling have predicted more complex strain distributions and increased critical layer thicknesses than in thin films, due to lateral strain relaxation at the surface, but the understanding of the growth and strain distributions in these complex struct
Nutrient iron sequestration is the most significant form of nutritional immunity and causes bacterial pathogens to evolve strategies of host iron scavenging. Cigarette smoking contains iron particulates altering lung and systemic iron homeostasis, which may enhance colonization in the lungs of patients suffering chronic obstructive pulmonary disease (COPD) by opportunistic pathogens such as nontyp
Technology foresight studies have become an important tool in identifying realistic ways of reducing the impact of modern energy systems on the climate and the environment. Studies on the future cost development of advanced energy technologies are of special interest. One approach widely adopted for the analysis of future cost is the experience curve approach. The question is, however, how robust

Det akuta behovet av att mildra klimatförändringarna har lett till utvecklingen av strategier för att minska utsläppen av växthusgaser. Carbon Capture and Utilization (CCU) har vuxit fram som en lovande teknik som inte bara syftar till att fånga upp koldioxidutsläpp (CO2) utan också använder den infångade koldioxide för att skapa produkter, och därigenom tillhandahålla en potentiell väg mot hållbaThe urgent need to mitigate climate change has prompted researchers to investigate novel strategies to reduce greenhouse gas emissions. One promising technology that might ease the way for sustainable and circular economies is carbon capture and utilization (CCU), which not only captures CO2 emissions but also uses them to produce valuable products. This thesis investigates the potential of CCU i
Bilindustrin genomgår en transformation som inte tidigare har skådats och samtliga aktörer längs med värdekedjan påverkas. Ett företag som befinner sig mitt i detta är Axess Logistics som erbjuder billogistiklösningar till generalagenter och återförsäljare på den skandinaviska marknaden. I tider av förändring uppkommer nya affärsmöjligheter, vilka Axess Logistics vill identifiera. En tydlig trend The automotive industry is undergoing an unprecedented transformation, and all actors along the value chain are affected. A company in the midst of this is Axess Logistics, which offers car logistics solutions to general agents and dealers in the Scandinavian market. In times of change, new business opportunities arise, which Axess Logistics wants to identify. An evident trend is the electrificati
Three different classification solutions for distinguishing events from non-events in surveillance audio are described and evaluated. The three compared methods are energy functions, Gaussian mixture modelling algorithms (GMM) and existing voice activity detectors (VAD). Recorded test signals with corresponding manually labelled ground truth files are used to determine the accuracies of the method
The synthesis of core@shell nanoparticles has predominantly been carried out by chemical methods or physical deposition of a shell material post-growth onto core particles. By combining immiscible materials that differ in surface energy, we demonstrate the spontaneous atomic rearrangement to monodisperse Cu@Ag core@shell particles directly in the aerosol phase, starting from pure Cu and Ag electro

The separation of hot carriers in semiconductors is of interest for applications such asthermovoltaic photodetection and third-generation photovoltaics. Semiconductor nanowiresoffer several potential advantages for effective hot-carrier separation such as: a high degree ofcontrol and flexibility in heterostructure-based band engineering, increased hot-carriertemperatures compared to bulk, and a ge
As the knowledge about anthropogenic impacts of climate change has grown, the awareness of the contributions from treatment of wastewater has widened the scope for wastewater treatment plants (WWTPs). Not only shall ever stricter effluent constraints be met, but also energy efficiency be increased, greenhouse gases mitigated and resources recovered. All under a constant pressure on costs. The main
Problems with bottlenecks in district heating networks occur when the pipes have too small dimensions to sufficiently meet customer needs. This may result in insufficient differential pressure in DH areas attached to these pipes. Bottlenecks are especially common in expanding DH networks, as previously sufficient pipe diameters may become too small when more DH consumers are connected to the DH ne
