  1. 6. Air-Sea Fluxes of CO2 : Analysis Methods and Impact on Carbon Budget

    Författare :Maria Norman; Anna Rutgersson; Erik Sahlée; William Drennan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; air-sea exchange; carbon dioxide; Baltic Sea; eddy-covariance method; inertial dissipation method; cospectral-peak method; Baltic Sea measurements; CO2 fluxes; Galathea 3 expedition; Baltic Sea modeling; water-side convection; coastal upwelling; carbon budget; Meteorology; Meteorologi;

    Sammanfattning : Carbon dioxide (CO2) is an important greenhouse gas, and the atmospheric concentration of CO2 has increased by more than 100 ppm since prior to the industrial revolution.  The global oceans are considered an important sink of atmospheric CO2, since approximately one third of the anthropogenic emissions are absorbed by the oceans.

  3. 7. Carbon exchange in boreal ecosystems: upscaling and the impacts of natural disturbances

    Författare :Julia Kelly; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Carbon fluxes; CH4; Climate change; CO2; Drought; Ecosystem respiration; Forest; Peatland; Remote sensing; Temperature; Thermal camera; UAV; Wildfire;

    Sammanfattning : Boreal forests and peatlands are globally significant carbon stores but they are threatened by rising air temperatures and changes in precipitation regimes and the frequency of natural disturbances. Predicting how the boreal biome will respond to climate change depends on being able to accurately model and upscale the greenhouse gas fluxes between these ecosystems and the atmosphere. LÄS MER

  4. 8. Biomass Retrieval in Topographic Boreal Forest using Polarimetric and Tomographic SAR in P- and L-band

    Författare :Erik Blomberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest Biomass; Tomography; SAR; L-band; EM Modelling; P-Band;

    Sammanfattning : Forests and their associated habitats are an integral part of Earth's biosphere and provide essential environmental services. There is an ever present need for accurate and economic monitoring of forest parameters such as biomass - of great interest both locally, for forest management and resource utilization, and globally as it represents stored atmospheric CO2 and one of the largest uncertainties in climate modelling.

  5. 9. Nanoplasmonic Sensing of Materials for Energy Applications

    Författare :Ferry Nugroho; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; localized surface plasmon resonance; sensors; palladium; PIM-1; microporous polymers; nanofabrication; film thickness dependence; indirect nanoplasmonic sensing; glass transition temperature; carbon capture and storage; adsorption; polymer:fullerene blends; organic photovoltaics; alloy nanoparticles; hydrogen sensors; plasmonic sensors;

    Sammanfattning : Sensors are omnipresent in our daily life. They are used in many applications ranging from the touch screen in our smartphones to more critical contexts such as pollution monitoring. LÄS MER

  7. 10. Supercritical CO2 technology in resource-effectiveproduction of functional and smart textiles

    Författare :Molla Tadesse Abate; Satoko Okubayashi; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supercritical CO2; Polyester; Functional textile; Smart textile; Antimicrobial; Antioxidant; UV protection; Textile UV-sensor; Curcumin; Chitosan; Photochromic materials; Photo-grafting; halochromic textile; Resource Recovery; Resursåtervinning;

    Sammanfattning : The demand for functional and smart textiles has risen nowadays due to the lifestyle change of human beings. Along with this, the production of functional and smart textiles is consistently increasing. LÄS MER
