  1. 21. Nanofiber networks, aerogels and biocomposites based on nanofibrillated cellulose from wood

    Författare :Houssine Sehaqui; Lars A. Berglund; Ton Peijs; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofibrillated cellulose; nanopaper; nanofiber; biocomposites; aerogel; foam; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Nanofibrillated cellulose (NFC) from wood is an interesting material constituent of high strength and high aspect ratio, which easily forms networks through interfibril secondary bonding including hydrogen bonds. This has been exploited in preparation of new materials, which extend the range of properties for existing cellulosic materials. LÄS MER

  3. 22. Unravelling protein stability and aggregation

    Författare :Tanja Weiffert; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein stability; protein aggregation; amyloid beta peptide; protein stabilization; split GFP; monellin; secretagogin; ; aggregation kinetics; toxicity; aggregation mechanism; coaggregation;

    Sammanfattning : Proteins are complex macromolecules that are fundamental to all living species. The stability of proteins are governed by non-covalent forces within the protein and between the protein and its surrounding environment. LÄS MER

  4. 23. Fluids, Gels and Crystals : Phase behavior of binary thermoresponsive microgel mixtures

    Författare :Jasper Immink; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colloidal phase behavior; microgel; binary mixture; colloidal gel; sequential gelation; patchy particle; binary crystal; crystal-to-crystal transition;

    Sammanfattning : Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction.

  5. 24. Venturing Further into the Field of 2D Materials and their Laminated Parent Phases

    Författare :Pernilla Helmer; Johanna Rosén; Jonas Björk; Martin Dahlqvist; Hannu-Pekka Komsa; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Density Functional Theory; Bonding analysis; Themodynamical stability; Electronic band structure; Computational screening; Dynamical stability; Nanolaminate; MXene; 2D material; Boridene; Chemical exfoliation; Selective etching;

    Sammanfattning : The field of 2D materials is a relatively young and rapidly growing area within materials science, which is concerned with atomically thin states of matter. Because of their intrinsic 2D morphology, 2D materials have exceptionally high surface to weight or surface to volume ratio. LÄS MER

  7. 25. Computational Studies on Homogeneous Water Oxidation Catalysts

    Författare :Ge Li; Mårten S. G. Ahlquist; Moyses Araujo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational studies; homogeneous; water oxidation catalysts; ruthenium; iron; mechanisms; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Sammanfattning : To combat the increasing energy demand and climate change, artificial photosynthesis is a promising approach to producing renewables by storing energy into chemicals and fuels. Water oxidation, responsible for offering electrons and protons to the reduction reactions, suffers from slow kinetics. LÄS MER
