  1. 6. Functional Fiber Based Materials for Microsystem Applications

    Författare :Carl Zandén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis explores the integration of functional electrospun micro- and nanofiber based materials in two fields of microsystem technology: fibrous scaffolds as cell culture substrates and fiber-reinforced metal matrix composites as thermal interface materials (TIMs).Electrospun structures have been found to carry great potential as biomimicking microenvironments for future tissue engineering and cell culture applications.

  3. 7. Processing and Properties of Nanostructured Biocomposites

    Författare :Natalia Herrera Vargas; Maria Soledad Peresin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : In this work, nanostructured biocomposite fibers and films with cellulose nanofibers (CNF), cellulose nanocrystals (CNC) and chitin nanocrystals (ChNC) were prepared using solutions mixing followed by electrospinning and melt compounding. The main processing challenges for these materials were to find parameters for: 1) fiber alignment in electrospinning, 2) feeding the nanomaterials into the extruder and 3) dispersion and distribution of the nanomaterials in the polymeric matrix.

  4. 8. Technology Development for Electrospinning of Novel Biomaterials Structures

    Författare :Anna Thorvaldsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : As the population gets older, the demands for new medical treatments increase since many of our most common diseases are related to age, including coronary heart disease, osteoarthritis and chronic ulcers. With this comes an increasing need for new biomaterial structures supporting and promoting tissue regeneration. LÄS MER

  5. 9. Porous structures based on nanopolysaccharides for medical applications

    Författare :Narges Naseri; Nazanin Emami; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : Recently, the use of bio-based nanomaterials has attracted much interest in medical applications due to their cytocompatibility, good moisture stability, good mechanical properties, hydrophilic surfaces and their ability to form porous structures. The aim of this work is to develop porous nanocomposites based on nanochitin and nanocellulose with controlled pore size and porosity in order to facilitate cell growth and interconnectivity and to investigate their potential in wound dressing and cartilage regeneration.

  7. 10. Composite Regenerative Scaffolds

    Författare :Elle Edin; Jöns Hilborn; May Griffith; Alicia El Haj; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nerve; neurite; regeneration; PEDOT; PEDOT:Tosylate; electrostimulation; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Sammanfattning : Regenerative medicine and tissue engineering solutions of heavily innervated tissues are at this point lacklustre. This thesis expands our knowledge of appropriate acellular scaffolds for tissue repair in general and nerve regeneration in particular. LÄS MER
