  1. 11. Modification of stable and degradable polymers by heterogeneous grafting

    Författare :Mattias Ohrlander; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis summarizes the investigations of the electronbeam initiated grafting of a hydrophilic monomer, acrylamide(AAm), onto three polymers; linear low density poly(ethylene)(LLDPE), poly(&-caprolactone) (PCL) and chemicallycrosslinked poly( 1,5-dioxepan-2-one) (PDXO-X). LLDPE and PCLare semicrystalline and PDXO-X is fully amorphous. LÄS MER

  3. 12. Light propagation and photonic functionalization of semi-ordered material (transparent wood)

    Författare :Adil Baitenov; Sergei Popov; Sergey Ponomarenko; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; light scattering; scattering material; hierarchical structure; FEM model; wood modification; random lasers; dye lasers; transparent wood; adsorption; diffusive media; Optics and Photonics; Optik och fotonik;

    Sammanfattning : Investigating novel materials requires understanding their chemical and optical properties, which allows for finding their uses through functionalization by chemical modification. In this thesis, we are focusing on a material with high anisotropic scattering - transparent wood. LÄS MER

  4. 13. Simulation-driven design : Motives, Means, and Opportunities

    Författare :Ulf Sellgren; KTH; []
    Nyckelord :CAD; CAE; FE method; Metamodel; Object model; PDM; Physical behavior; System; Mechanical engineering; Maskinteknik;

    Sammanfattning : Efficiency and innovative problem solving are contradictory requirements for productdevelopment (PD), and both requirements must be satisfied in companies that strive to remainor to become competitive. Efficiency is strongly related to ”doing things right”, whereasinnovative problem solving and creativity is focused on ”doing the right things”. LÄS MER

  5. 14. Particle interactions at the nanoscale : From colloidal processing to self-assembled arrays

    Författare :Bertrand Faure; Lennart Bergström; Albert Philipse; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Colloidal processing; nanoparticles; colloidal forces; titania; iron oxide; Hamaker constant; surface modification; rheology; Monte Carlo simulations; collective properties; superparamagnetism; finite-size effects; Materials Chemistry; materialkemi;

    Sammanfattning : Nanostructured materials are the next generation of high-performance materials, harnessing the novel properties of their nanosized constituents. The controlled assembly of nanosized particles and the design of the optimal nanostructure require a detailed understanding of particle interactions and robust methods to tune them. LÄS MER

  7. 15. Tailoring Cellulose Nanofibrils for Advanced Materials

    Författare :Núria Butchosa Robles; Qi Zhou; Kristiina Oksman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibrils; bacterial cellulose; surface modification; carboxymethyl cellulose; polyethylene glycol; chitin nanocrystals; bactericidal activity; nanofibrils orientation; water redispersability; mechanical properties; dye removal; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cellulose nanofibrils (CNFs) are nanoscale fibers of high aspect ratio that can be isolated from a wide variety of cellulosic sources, including wood and bacterial cellulose. With high strength despite of their low density, CNFs are a promising renewable building block for the preparation of nanostructured materials and composites. LÄS MER
