  1. 1. Functional Degradable Polymers : from the monomeric point of view

    Författare :Peter Olsén; Ann-Christine Albertsson; Karin Docent; Andrew Dove; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Degradable polymers is key, within the future vison, of creating a sustainable society were all aspects, cradle to grave, can be realized in a sustainable way. It is imperative to consider, how the monomer is formed, its polymerization, the material properties created and the final degradation behavior. LÄS MER

  3. 2. Nanomechanics – Quantum Size Effects, Contacts, and Triboelectricity

    Författare :Martin Olsen; Jonas Örtegren; Håkan Olin; Per Gradin; Peter Glans; Rusen Yang; Mittuniversitetet; []
    Nyckelord :triboelectricity; adatom; ion; charge; mound; quantum size effect; triboelctric nanogenerator; TENG; wind driven; contact; nanomechanics; fri electron model; nanowire cantilever;

    Sammanfattning : Nanomechanics is different from the mechanics that we experience in everyday life. At the nano-scale, typically defined as 1 to 100 nanometers, some phenomena are of crucial importance, while the same phenomena can be completely neglected on a larger scale. LÄS MER

  4. 3. Thermodynamic Toolkit for Chemical Recycling to Monomer

    Författare :Linnea Cederholm; Karin Odelius; Minna Hakkarainen; Peter Olsen; Louis Pitet; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chemical recycling to monomer; polymerization thermodynamics; ring-opening polymerization; solvent effect; polyester; polycarbonate; copolymer; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The design of polymeric materials for a circular economy is, to a largeextent, a challenge of thermodynamics. The work presented in this thesishas explored the thermodynamic features of ring-opening polymerizationand ring-closing depolymerization, to develop polymeric materials andrecycling strategies for chemical recycling to monomer.

  5. 4. Tailoring and Characterization of Polymer-linked Fibrillar Structures

    Författare :Maria F. Cortes Ruiz; Lars Wågberg; Peter Olsén; Michael Malkoch; Gil Garnier; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose nanofibrils; hydrogels; cellulose fibres; functionalisation; structure-property relationships.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The development of sustainable and renewable materials is paramount in today’s society. As the most abundant biopolymer on Earth, cellulose from cellulose-rich fibres is an excellent alternative for advanced and innovative material solutions. LÄS MER

  7. 5. SEMANTIC INFORMATION AND PHYSICAL MULTI-DOMAIN MODELING AND SIMULATION FOR POWER SYSTEMS

    Författare :Francisco José Gómez; Luigi Vanfretti; Svein Olsen; Peter Palensky; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; POWER SYSTEMS; MODELING; SIMULATION; CIM; MODELICA; ISO 15926; MULTI-DOMAIN; UML; SYSML; Energy Technology; Energiteknik;

    Sammanfattning : There are different reasons for combining different modeling languages and simulationlanguages: Exchange of more detailed information about power network components, theirparameters and, most importantly, mathematical equations describing their behavior andthe exchange of a mathematical description, using equation-based languages (e.g. LÄS MER
