  1. 11. Performance of on-site systems and a green wall for greywater treatment

    Författare :Mashreki Sami; Annelie Hedström; Elisabeth Kvarnström; Inga Herrmann; Sahar Dalameh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Greywater contains inorganic and organic substances, nutrients, pathogens, micropollutants and microplastics. Source-separated greywater using decentralized systems can potentially provide energy-efficient and low-maintenance treatment. LÄS MER

  3. 12. Development of hierarchical cellulosic reinforcement for polymer composites

    Författare :Abdelghani Hajlane; Angelika Bachinger; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Cellulose is an environmentally friendly material which is obtainable in vast quantities, since it is present in every plant. Cellulosic fibers are commercially found in two forms: natural (flax, hemp, cotton, sisal, wood, etc.) and regenerated cellulose fibers (RCF). LÄS MER

  4. 13. Technical cost modelling and efficient design of lightweight composites in structural applications

    Författare :Mathilda Karlsson Hagnell; Malin Åkermo; Dan Zenkert; Gerhard Ziegmann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technical cost modelling; composite materials; carbon fibre; lightweight design; optimization; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : A lightweight transport design reduces fuel costs and emissions and can be achieved through the use of fibre-reinforced composite materials. Although lightweight, the composite raw material can be expensive and the sequential component production challenging and costly. LÄS MER

  5. 14. Biochemical Study and Technical Applications of Fungal Pectinase

    Författare :Jing Zhang; Gunnar Johansson; Gunnar Henriksson; Jonas Hafrén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Pectin; pectinase; polygalacturonan; polygalacturonase; retting; flax; enzymatic retting; pre-incubation; discoloration; pulping; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : Pectinases are a group of enzymes produced by bacteria, fungi, higher plants and animals. Pectinases can modify and degrade pectins, a class of heterogeneous and multifunctional polysaccharides present in middle lamellae and primary cell walls of plants. LÄS MER

  7. 15. Renewable Composites Prepared from Biobased Thermoset Resins

    Författare :Dan Åkesson; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Renewable; natural fibre; composite; biobased thermoset resin;

    Sammanfattning : In our efforts to create a more sustainable society, several researchers have tried to prepare composites from renewable materials in recent years. The use of natural fibres for reinforcement of composites has been relatively well studied. LÄS MER
