  1. 1. From bio-based residues to nanofibers using mechanical fibrillation for functional biomaterials

    Författare :Linn Berglund; Kristiina Oksman; Monika Österberg; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofibers; Industrial residues; Ultrafine grinding; Energy-efficiency; Network formation; Hydrogel; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : Bio-based resource utilization in different forms has been driven by societal, industrial and academic research interests towards the development of “green”, sustainable materials from renewable sources. Within this context, exploiting biomass from different industrial residues is further advantageous from an environmental and economic point of view, leading to minimization of residues by means of waste treatment and to the development of high-addedvalue- products.

    Sammanfattning : The use of acoustic waves initiated by the deformation of a microchannel is one method for generating monodisperse, micrometer-sized droplets from small orifices and is employed in piezo-electric inkjet printheads. These printheads are used in both graphical printing and digital fabrication, where functionalities, such as optical, biological, electrical or mechanical, are being produced locally. LÄS MER

  4. 4. Biological Sensing and DNA Templated Electronics Using Conjugated Polymers

    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; conjugated polymer; conjugated polyelectrolyte; DNA; sensor; nanowire; Bioengineering; Bioteknik;

    Sammanfattning : Conjugated polymers have been found useful in a wide range of applications such as solar cells, sensor elements and printed electronics, due to their optical and electronic properties. Functionalization with charged side chains has enabled water solubility, resulting in an enhanced interaction with biomolecules. LÄS MER

  5. 5. Spatially Controlled Covalent Immobilization of Biomolecules on Silicon Surfaces

    Författare :Elisabeth Pavlovic; Sven Oscarsson; Marcus Textor; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Biotechnology; silicon oxide; electrooxidation; sulfur; nanotechnology; self-assembled monolayers; atomic force microscopy; electron spectroscopy for chemical analysis; biomolecules; covalent immobilization; reversibility; Bioteknik; Bioengineering; Bioteknik;

    Sammanfattning : The work described in this thesis aims to achieving surface patterning through chemical activation of thiolated silicon oxide surfaces, resulting in a spatially controlled covalent immobilization of biomolecules with high resolution.Existing chemical methods to immobilize molecules on surfaces do not reach below the micrometer scale while the ones allowing for spatial control mostly lead to non-covalent adsorption of molecules on surfaces, or require several successive chemical reactions to obtain the final covalent immobilization.
