  1. 21. Wood-derived lignin-based fibers as supercapacitor electrodes

    Författare :Azega Rajendra Babu Kalai Arasi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; lignin; green electrode materials; energy storage; supercapacitor;

    Sammanfattning : Today, in order to replace fossil energy sources with renewable energy sources such as solar and wind, reliable energy storage systems that can provide power regardless of the intermittent nature of the energy sources must be created. Especially with the future’s rising energy demands the development of such energy storage systems from green-collar materials with the least negative environmental impact is pressing. LÄS MER

  3. 22. Titanium(IV) Phosphates : The Next Generation of Wastewater Sorbents

    Författare :Mylene Trublet; Oleg Antzutkin; Anna-Carin Larsson; Marina Maslova; Nigel Clayden; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Treatment of industrial waters containing heavy metal ions is essential before being discharged into the environment. Consequently, European regulations have been established to control and limit the amount of heavy metals released. LÄS MER

  4. 23. Quinoa Stalks Glucuronoarabinoxylan : Biorefinery,xylooligosaccharides production and potential applications

    Författare :Daniel Salas Veizaga; Bioteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quinoa stalks; Glucuronoarabinoxylan; Xylooligosaccharides; Xylanases; Probiotics;

    Sammanfattning : Quinoa stalks were used as a source of hemicellulose for XOs production and further as prebiotic source for probiotic bacteria. Three methods for extraction of hemicellulose were used, of which alkaline extraction (NaOH [0.5 M]) was the optimum method. LÄS MER

  5. 24. Covalent functionalization of carbon nanomaterials for bioelectrochemical applications

    Författare :Naoual Allali; Alexander Soldatov; Manuel Dossot; Victor Mamane; Silvia Giordani; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Sammanfattning : Carbon nanotubes (CTNs) are renowned for their exceptional electronic and mechanical properties. Their structure can be considered as rolling up a graphene sheet along a specific crystallographic direction, leading to a 1D confinement of the electronic wavefunction of the delocalized electrons along the perimeter of the cylindrical structure thus obtained.

  7. 25. Formation and Transformation of Atmospheric Brown Carbon (BrC)

    Författare :Kalyan Mitra; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; brown carbon BrC ; primary organic aerosol POA ; secondary organic aerosol SOA ; BrC bleaching; BrC browning; Toluene photo-oxidation; NOx; Ammonia; NH3; acidity effects; light absorption;

    Sammanfattning : Atmospheric brown carbon (BrC) aerosol absorbs light in the UV-Vis spectrum and has poorly constrained but potentially large climate forcing impacts. Most current climate models lack detailed chemistry and interlinked properties of atmospheric BrC, that induce large uncertainties in radiative forcing predictions. LÄS MER
