  1. 21. Nanocellulose-based materials: from colloidal assembly to functional films

    Författare :Yingxin Liu; Lennart Bergström; German Salazar-Alvarez; Orlando Rojas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materials Chemistry; materialkemi;

    Sammanfattning : The assembly of nature-based nanomaterials into complex architectures is both a design principle of biological composites, e.g., wood and nacre with outstanding properties and a promising route for developing functional macroscopic materials. LÄS MER

  3. 22. Termination and Cost Analysis : Complexity and Precision Issues

    Författare :Abu Naser Masud; Samir Genaim; Germán Puebla; Technical University of Madrid; []
    Nyckelord :;

    Sammanfattning : The research in this thesis is related to static cost and termination analysis.Cost analysis aims at estimating the amount of resources that a given programconsumes during the execution, and termination analysis aims at proving thatthe execution of a given program will eventually terminate.

  4. 23. Power System Operation Planning and Wind Power Curtailment : Efficient Methods for Power System Scheduling and Integration Studies of Variable Renewable Energy

    Författare :Elis Nycander; Lennart Söder; Mehrdad Ghandari; Robert Eriksson; Germán Morales-España; Benjamin Hobbs; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Variable renewable energy; wind power integration; production cost model; power-based unit commitment; wind power scenarios; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : To reduce carbon dioxide emissions, variable renewable energy (VRE) sources are replacing conventional fossil-based power plants for electricity generation. Due to the variability and uncertainty of weather dependent VRE sources, there can be situations when it is not possible to accommodate all the available VRE production, and VRE sources have to be curtailed.

  5. 24. Laser sintered materials with Non-equilibrium structures

    Författare :Bin Qian; Zhijian Shen; Germán F. de la Fuente; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser sintering; Materials; Non-equilibrium structures; microstructure; hierarchical structure; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : This thesis is focused on achieving materials with non-equilibrium structures fabricated by high-energy laser sintering. The chosen precursor materials have rigid and inert structures like high-melting point ceramics or metals. LÄS MER

  7. 25. Fabrication of nanocellulose-based materials : Liquid crystalline phase formation and design of inorganic–nanocellulose hybrids

    Författare :Christina Schütz; Lennart Bergström; Germán Salazar-Alvarez; Mark MacLachlan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materials Chemistry; materialkemi;

    Sammanfattning : The increasing need to replace fossil fuels as a source of energy and raw material is resulting in extensive research efforts towards identifying and developing high performance materials and devices based on renewable sources. Cellulose being the most versatile and abundant biopolymer in nature is one of the obvious choices. LÄS MER
