    Sammanfattning : This thesis is focused on studies on the environmental fate and methodological improvements for determination of the global contaminants, PCBs and DDTs, and locally discharged phenolics, e.g. 4,5,6-trichloroguaiacol (4,5,6-TCG), and their transformation products. LÄS MER

  3. 2. Design, Synthesis and Characterization of Nanostructured Thermoelectric Materials

    Författare :Bejan Hamawandi; Muhammet Toprak; MARISOL Martin Gonzalez; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materials chemistry; Material and Nano Physics; Material- och nanofysik; Fysik; Physics;

    Sammanfattning : The demand for energy is rapidly increasing, triggering more carbon emission and global warming. Alternative green energy sources are essential to secure the future generation from the effect of pollution and global warming. LÄS MER

  4. 3. Optimisation and Incentive Mechanisms for Robust Generation Dispatch and Capacity Investment in Electricity Markets

    Författare :Lamia Varawala; György Dán; Mohammad Reza Hesamzadeh; José Manuel Arroyo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal power flow; Look-ahead; $N-k$ contingency criterion; Renewable energy; Environmental externalities; Electricity generation capacity; Strategic behaviour; Incentives;

    Sammanfattning : Power systems constitute a large-scale critical infrastructure and therefore, it is crucial that their operation be robust to deviations from normal functioning of its independent components. Furthermore, due to their large size, any inefficiencies in electricity market design can be very costly and therefore, must be optimised. LÄS MER

  5. 4. Photophysics of Perovskite Nano- and Microcrystals

    Författare :Junsheng Chen; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrafast spectroscopy; Two-photon absorption; Perovskite; Nanocrystals; Photostability; Lead free perovskite;

    Sammanfattning : The demand and consumption of energy is increasing dramatically all around the world. Broad adoption of fossil fuels has triggered an enormous threat to the environment. To ensure sustainability of our species and habitat, new solutions to fulfill the energy demand have to be found. LÄS MER

  7. 5. An Emerging Product Approach in Environmental Law: Incorporating the life cycle perspective

    Författare :Carl Dalhammar; Internationella miljöinstitutet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Trade and environment; Product regulation; IPP; Integrated product policy; Life cycle thinking; Environmental product policy; Environmental law; Miljörätt;

    Sammanfattning : One of the noticeable trends in recent years is that products have received increasing attention in environmental policy. The focus on products and their life cycle impacts is often referred to as ?life cycle thinking?. LÄS MER
