  1. 11. Exploring the ecotoxicity of microparticle debris

    Författare :Zandra Gerdes; Elena Gorokhova; Martin Ogonowski; Tamara Galloway; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microplastics as emerging pollutants; hazard assessment; ecotoxicological experimental design; aquatic toxicology; chemical vector; suspended solids; reference particles; crustaceans as test organisms; behavioural assays in ecotoxicology; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The global distribution and anticipated increase of environmental microplastic (MP) pollution are concerning. However, while the impacts of macroplastic litter on wildlife are apparent, we know relatively little about the MP hazard potential. LÄS MER

  2. 12. Microbiome Of Ecotoxicity Assays

    Författare :Asa Motiei; Elena Gorokhova; Natàlia Corcoll; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biofilm; Microplastics; Suspended solids; Aquatic toxicology; Daphnia magna; Ecotoxicology; Bacterial colonization; Particle aggregation; Microbiome interaction; Standardization; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Microorganisms are ubiquitous and present in animal microbiomes, particulates, and colonizable surfaces of test systems. From an ecotoxicological perspective, they are metabolically active biological compartments that respond to test conditions, including test substances. LÄS MER

  3. 13. Pressurized entrained flow gasification of pulverized biomass : Experimental characterization of process performance

    Författare :Fredrik Weiland; Thomas Kolb; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : The anthropogenic emissions of greenhouse gases (e.g. CO2), mostly connected to the use of fossil fuels, to the atmosphere have increased during the last century and there is significant evidence that this is the main reason for the recent global temperature rise. LÄS MER

  4. 14. Preparation and characterisation of refractory whiskers and selected alumina composites

    Författare :Mats Carlsson; Mats Johnsson; Tor Grande; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; VLS-growth; Characterisation; Whiskers; Sintering; Ceramic composites; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : A whisker is a common name of single crystalline inorganic fibre of small dimensions, typically 0.5-1 μm in diameter and 20-50 μm in length. Whiskers are mainly used as reinforcement of ceramics. This work describes the synthesis and characterisation of new whisker types. LÄS MER

  5. 15. Characteristic Properties and Applications of Fine Particles in Biomass Gasification

    Författare :Azhar Malik; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Biomass; Fine particles; catalyst deactivation; dilution probe sampling; organic;

    Sammanfattning : The gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. LÄS MER
