    Författare :Ingvar Sundh; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : .... LÄS MER

  3. 2. The importance of terrestrial carbon in plankton food webs

    Författare :Cesar Bolivar Daniel; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecology; lakes; carbon; zooplankton; Spumella elongata; Poterioochromonas malhamensis; flagellates; bacteria; stable isotopes; photochemistry; autochthonous; DOC; allochthonous; plankton; Ekologi; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : Allochthonous substances, i.e. produced in terrestrial ecosystems, are known to fuel bacterial production in humic lakes. I observed that allochthonous carbon subsidizes bacteria even at high levels of phytoplankton biomass. LÄS MER

  4. 3. Cellulose–Assisted Dispersion of Carbon Nanotubes : From Colloids to Composites

    Författare :Alireza Hajian; Lars Berglund; Milo Shaffer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocelluloses; Carbon nanotubes; Composites; Colloids; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : It is a challenge to disperse nanoparticles to obtain a nanostructured composite. This thesis aims at providing a new route to fabricate carbon nanotube (CNT) composites and suggests mechanisms for nanocellulose–CNT interactions. This route is based on unmodified CNT dispersed in water with the help of nanocellulose. LÄS MER

  5. 4. Towards sustainable shipping: Evaluating the environmental impact of electrofuels

    Författare :Elin Malmgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; environmental assessment; LCA; emerging technology; marine fuels; human health; future fuel; sustainable shipping; carbon utilization; power-to-x; carbon capture;

    Sammanfattning : The global, local, and regional environment is under pressure from human activity. Changes in the environment can be beneficial and strived for, but environmental and health problems need to be considered when we design human activities. LÄS MER
