  2. 1. Investigation of CO2 interactions with cellulose dissolved in the NaOH(aq) system

    Author : Maria Gunnarsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DBU; ATR-IR spectroscopy; NaOH aq ; dissolution; NMR spectroscopy; CO2; cellulose;

    Abstract : Cellulose derived from wood can be used as raw material for production of textile fibres, making it a renewable alternative to fossil oil. One of the key steps in this process is dissolution of the cellulose. READ MORE

  4. 2. Understanding overlooked molecular interactions in the cellulose/NaOH(aq) system

    Author : Maria Gunnarsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ATR-IR; dissolution; cellulose; NMR; urea; CO2; NaOH aq ;

    Abstract : The cold NaOH(aq) system is a promising process for the production of textile fibres. Although the process has been studied for almost a century, there remain unsolved research issues, especially regarding the dissolution mechanism. READ MORE

  5. 3. On the use of genomics to asses environmental risks of pharmaceuticals

    Author : Lina-Maria Gunnarsson; Göteborgs universitet; []
    Keywords : comparative pharmacology; ecotoxicology; fish; microarray; genomics; wastewater treatment;

    Abstract : Many drugs are found in the aquatic environment and are therefore a cause for concern. Low concentrations of active ingredients from human pharmaceuticals reach the environment via sewage treatment plants, mainly as a result of excretion. READ MORE

  6. 4. In situ remediation of contaminated sediments using thin-layer capping : effectiveness in contaminant retention and ecological implications

    Author : Göran Samuelsson; Jonas Gunnarsson; Maria Granberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thin layer capping; sediment remediation; activated carbon; contaminated sediment; benthic community; Systems Ecology; systemekologi;

    Abstract : Hydrophobic organic contaminants (HOCs) often reside in sediment sorbed to particles, most tightly to particles with high content of organic carbon. If persistent, such pollutants can accumulate in the sediment for many years and constitute a contamination risk for sediment-living organisms and organisms at higher trophic levels, including humans.
