  2. 11. Development of hierarchical cellulosic reinforcement for polymer composites

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

    Abstract : 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). READ MORE

  4. 12. Tailored cellulosic materials by physical adsorption of polyelectrolytes

    Author : Andrew Marais; Lars Wågberg; Andreas Fery; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The growing interest in using bio-based resources has made forest-based cellulose (used as fibre and nanofibril building elements) a good candidate for the development of new materials. In order to be used in commercial applications, cellulose must however be processed and/or functionalized to provide the final material with specific properties. READ MORE

  5. 13. Multifunctionality and Durability of Cellulosic Fiber Reinforced Polymer Composites

    Author : Zainab Al-Maqdasi; Roberts Joffe; Nazanin Emami; Liva Pupure; Tatiana Glaskova-Kuzmina; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera kompositmaterial;

    Abstract : The overall objective of this thesis is to develop and evaluate cellulose-based fiber composites with added multifunctionality for advanced applications. In the strive towards sustainable societies and industries, materials as well as production processes need to be assessed against the sustainability criteria and selected accordingly. READ MORE

  6. 14. Ethanol Production from Cellulosic Biomass by Encapsulated Saccharomyces cerevisiae

    Author : Farid Talebnia; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; encapsulated cells; ethanol; s.cerevisiae; dilute-acid hydrolyzate; in situ detoxification; furfural; orange peels; experimental design; immobilization; limonene;

    Abstract : Unstable oil markets with rising environmental concerns have revived widespread interest in production of fuel ethanol from renewable materials. Cellulosic materials are abundant and prominent feedstocks for cheap ethanol production. However, due to recalcitrant structure of these materials, pretreatment is a prerequisite. READ MORE

  7. 15. Pretreatment of cellulosic waste and high rate biogas production

    Author : Solmaz Aslanzadeh; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Two-stage anaerobic digestion; N-methylmorpholine N-oxide NMMO pretreatment; Lignocelluloses; Textile waste; Biofuels; Resursåtervinning; Resource Recovery;

    Abstract : The application of anaerobic digestion technology is growing worldwide, mainly because of its environmental benefits. Nevertheless, anaerobic degradation is a rather slow and sensitive process. One of the reasons is the recalcitrance nature of certain fractions of the substrate (e.g. READ MORE
