  4. 3. Eco-designed functionalization of polyester fabric

    Författare :Tove Agnhage; Guido Sonnemann; Isabelle Vroman; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eco-design; Life cycle assessment; Madder; Anthraquinone; Bioactive; Multifunctional; Polyester; Textil och mode generell ; Textiles and Fashion General ;

    Sammanfattning : There is an increased awareness of the textile dyeing and finishing sector’s high impact on the environment due to high water consumption, polluted wastewater, and inefficient use of energy. To reduce environmental impacts, researchers propose the use of dyes from natural sources. LÄS MER

  5. 4. Pretreatment and Enzymatic Treatment of Spruce : A functional designed wood components separation for a future biorefinery

    Författare :Yan Wang; Gunnar Henriksson; Mikael E. Lindström; Hans Theliander; Martin Lawoko; Adriaan van Heiningen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft cooking; extended impregnation; enzymes; chemo-enzymatic separation process; peeling reaction; sodium borohydride; polysulfide; anthraquinone; sodium dithionite; mild steam explosion; biorefinery.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The three main components of wood, namely, cellulose, hemicellulose, and lignin, can be used in various areas. However, since lignin covalently crosslinks with wood polysaccharides creating networks that is an obstacle for extraction, direct extraction of different wood components in high yield is not an easy matter.

  7. 5. Organic electronic materials for hydrogen peroxide production

    Författare :Maciej Gryszel; Eric Glowacki; Magnus Jonsson; Erin Ratcliff; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrogen peroxide; catalysis; organic materials; electronics;

    Sammanfattning : Hydrogen peroxide (H2O2) is an important oxidant, used in various fields of industry, such as paper manufacturing, production of polymers, detergents, and cosmetics. Considering that the molecule degrades only to H2O and O2, it is regarded as a green chemical. LÄS MER
