    Sammanfattning : Within healthcare there is a market pull for biomedical devices that can rapidly perform laboratory processes, such as diagnostic testing, in a hand-held format. For this reason, biomedical devices must become smaller, more sophisticated, and easier to use for a reasonable cost. LÄS MER

  4. 8. Thiol-ene Nanostructuring

    Författare :Reza Zandi Shafagh; Klas Tommy Haraldsson; Wouter van der Wijngaart; Niels Bent Larsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanostructuring; thiol-ene; OSTE; electron beam lithography EBL ; reaction injection molding RIM ; nanoimprint lithography NIL ; BioNEMS; QCM; digital bioassay; protein patterning; Lab-on-a-chip; polymer;

    Sammanfattning : Improving the health and well-being of humankind does not only constitutepart of our moral codes, but is also enlisted as the number three goal ofthe 2030 agenda for sustainable development set by the UN. Fulfilling suchobjective in the regions of resource-poor settings or for age groups with morevulnerability to infectious agents demands immediate actions. LÄS MER

  5. 9. Natural fiber composites : optimization of microstructure and processing parameters

    Författare :Birgitha Nyström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Sammanfattning : Natural fiber composites, (NFC) are defined in this work as a group of materials where at least the fibers originates from renewable and CO2 neutral resources. NFC consists of a polymer matrix and a natural fiber. The fibers which originate from wood or plants can replace non-renewable fibers or fillers or simply replace part of the plastic. LÄS MER

  7. 10. Diffractive Optical Elements: Fabrication, Replication, and Applications and Optical Properties of a Visual Field Test

    Författare :Fredrik Nikolajeff; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perimetry; beam homogenizing; antireflection; high-pass spatial frequency target; proximity effect; electron beam lithography; replication; successive development; diffractive optical element; axicon;

    Sammanfattning : This thesis mainly treats the fabrication, replication and applications of diffractive optical elements. A smaller part deals with optical properties of a visual field test. Diffractive optical elements are computer-generated micro-optic components that use diffraction to manipulate light. LÄS MER
