  2. 1. Nanolatexes: a versatile toolbox for cellulose modification

    Author : Alexandros Efraim Alexakis; Eva Malmström; Justin Zoppe; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanolatexes; RAFT; PISA; adsorption; cellulose; modification; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Cellulosic materials are widely used in our everyday lives, ranging from paperand packaging to biomedical applications. However, in most applications, cellulose must coexist with hydrophobic polymers which can be challenging due to its hydrophilic character. This has encouraged the exploration of chemical and physical modifications of cellulose. READ MORE

  4. 2. Design of Functional Polymeric Nanoparticles for Biomedical Applications

    Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PISA; latex; RAFT; Cellulose Nanofibrils; Cellulose Nanocrystals; Nanocomposites; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : This thesis is focused on applying modification chemistry to already known cellulosic substrates from wood (i.e. cellulose nanofibrils, CNFs, and cellulose nanocrystals, CNCs). READ MORE

  7. 5. Prion-infection and Cellular Signaling : Influence of scrapie-infection on lipid raft-associated proteins

    Author : Hanna Gyllberg; Katarina Bedecs; Albert Taraboulos; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Prion diseases are a group of fatal neurodegenerative diseases affecting almost all mammals including humans. The diseases are caused by formation of the misfolded isoform of the cellular prion protein (PrPC) to the disease causing PrPSc. READ MORE
