  1. 21. Light polarization in single molecule spectroscopy: From visualization of structural anisotropy and energy transfer to super-resolution imaging with orientational contrast

    Författare :Daniel Thomsson; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Single-molecule spectroscopy; π-conjugated polymers; blinking; fluorescence brightness; low temperature; polarization anisotropy; 2D polarization; energy transfer; super resolution; Fourier transform;

    Sammanfattning : Π-conjugated polymers are an important class of materials which can be used in e.g. photoelectric (solar cells) or electroluminescent (displays) devices. These materials are implemented in a number of applications these days since a lot is already known about them. LÄS MER

  3. 22. A comprehensive approach to building-stock modelling - Assessing the impact of renovating urban housing stocks

    Författare :Magnus Österbring; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy performance certificate; costeffectiveness; GIS; LCA; building valuation; renovation; refurbishment; Building-stock modelling; multi-family buildings; energy;

    Sammanfattning : The existing building stock provide a possibility for cost-efficient energy efficiency measures and related reductions in greenhouse-gas emissions. As the rate of renewal in the buildingstock is low, energy efficiency measures need to be applied when renovation is being done in order to reach climate goals. LÄS MER

  4. 23. Land-Use and Climate Effects of Bioenergy: Carbon balances of Swedish forest bioenergy systems – and – Geospatial biomass supply-and-demand matching for Europe

    Författare :Olivia Cintas Sanchez; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GIS; EU; bioenergy; Sweden; agriculture; residues; Forestry; climate change; GHG balances;

    Sammanfattning : In order to keep global warming below 2 degrees Celsius, greenhouse gas emissions have to be drastically reduced. Bioenergy can play a role in climate change mitigation by substituting for energy from fossil fuels; however, biomass is a limited resource associated with emissions from land use and land-use change.

  5. 24. Quantitative laser diagnostics of gas-phase potassium species in biomass combustion and gasification

    Författare :Emil Thorin; Florian Schmidt; Markus Broström; Zhongshan Li; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermochemical conversion; pyrolysis; phosphorus; single pellet; entrained-flow; in situ; spectroscopy; photofragmentation; imaging; numerical modelling; fysik; Physics;

    Sammanfattning : Thermochemical energy conversion processes, such as combustion and gasification, are applied worldwide for generation of electricity, heat and synthesis of chemicals. Today, these processes are mostly run on non-renewable, fossil fuels and constitute a major source of carbon dioxide emissions. LÄS MER

  7. 25. Numerical and experimental study of confluent jets supply device with variable airflow

    Författare :Harald Andersson; Bahram Moshfegh; Mathias Cehlin; Fredrik Karlsson; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Confluent jets; Air distribution system; Air supply device; Ventilation performance; Indoor air quality; Thermal comfort; Experimental study; Laser Doppler Anemometry LDA ; Computational fluid dynamics CFD ; Shear stress transport SST k – ω ; confluent jets; luftdistributionssystem; tilluftsdon; ventilationsprestanda; inomhusluftkvalitet; termisk komfort; experimentell studie; Laser-Doppler-anemometri LDA ; Computational fluid dynamics CFD ; turbulens model SST k – ω ; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : In recent years, application of confluent jets for design of ventilation supply devices has been studied. Similarly, numerus studies have been made on the potential and application of variable air volume (VAV) in order to reduce the energy demand of ventilation systems. LÄS MER
