  2. 2. Cellulose nanofibril materials with controlled structure the influence of colloidal interactions

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Andreas Fall; KTH.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Colloidal stability; cellulose nanofibrils; nanofibers; nanostructured materials; biocomposite; DLVO; gel;

    Sammanfattning : Nanoparticles are very interesting components. Due to their very large specific surface area they possess properties in between molecules and macroscopic materials. In addition, a material built up of hierarchically assembled nanoparticles could obtain unique properties, not possessed by the nanoparticles themself. LÄS MER

  3. 3. Colloidal interactions and orientation of nanocellulose particles

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Andreas Fall; KTH.; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NFC; CNC; CNF; MFC nanocellulose; colloidal stability; orientation;

    Sammanfattning : Nanoparticles are very interesting building blocks. Their large surface-to-bulk ratio gives them different properties from those of larger particles. Controlling their assembly can greatly affect macroscopic material properties. LÄS MER

  4. 4. Sterically stabilised liposomes and related lipid aggregates Fundamental studies on aggragate structure and stability

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Markus Johnsson; Uppsala universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; liposome; steric stabilisation; colloidal stability; cryo-TEM; drug delivery; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Various aspects of and approaches towards the steric stabilisation of liposomes have been investigated, mainly by use of fluorescence techniques and cryo-transmission electron microscopy (cryo-TEM). It is shown that PEG(2000)-lipids can be incorporated in the liposome membrane up to a critical concentration of 8-10 mol% without any observable structural perturbations. LÄS MER

  5. 5. Colloidal carrier substances : Properties and impact on trace metal distribution in natural waters

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Anna Ledin; Linköpings universitet.; Linköpings universitet.; [1993]
