  1. 6. Development of Vessel Phantoms for Ultrasound Methods

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Benjamin Meirza; [2018]
    Nyckelord :Longitudinal movement of the arterial wall; Vasa vasourom; Micro vessles; SEBS; Ultrasound phantom.; Technology and Engineering;

    Sammanfattning : Phantoms mimicking the specific mechanical and acoustic properties of human tissues are essential in the development and evaluation of novel ultrasound methods. In this work, various ultrasound phantoms are proposed to be used in the development of ultrasound methods to investigate the arterial walls longitudinal movements influence on the vasa vasorum circulation.

  3. 7. Block Copolymer Lithographyfor Nano-porous Oxide Thin Films

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yandi Liu; [2018]
    Nyckelord :Block Copolymer; Lithography; Nanopatterning; Reactive-Ion Etching; Oxide Thin Films; Blockcopolymer; Litografi; Nanopakning; Reaktion-Jon Etsning; Oxidtunnfilmerna;

    Sammanfattning : This thesis focuses on employing a new patterning technique called block copolymer lithography to transfer the nano-porous pattern from the polymer template to the underlying oxide thin film. Nano-porous block copolymer films are produced by spin-coating polymer solution on wafers followed by annealing, UV exposure and development processes. LÄS MER

  4. 8. Bacterial interactions across a porous membrane

    Master-uppsats, Lunds universitet/Tillämpad biokemi

    Författare :Malin Alsved; Karin Hjerpe; [2015]
    Nyckelord :tillämpad biokemi; applied biochemistry; Biology and Life Sciences; Chemistry;

    Sammanfattning : Deepening our knowledge about bacterial infections is of high priority in the work against antimicrobial resistance. Many infections are as well polymicrobial, and the different bacterial species are able to affect each other by cell-cell communication. LÄS MER

  5. 9. Modification of nanofibrillated cellulose with stimuli-responsive polymers

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Carmen Cobo Sanchez; [2012]
    Nyckelord :thermoresponsive; nanofibrillated cellulose; biocomposites; block-copolymer; stimuliresponsive;

    Sammanfattning : Research of new sustainable and low cost materials, such as cellulose, is of high interest. Modifications of the cellulose can be performed in order to create a “smart” material which responds to external stimuli, such as variations in pH and temperature, by changing its properties.

  7. 10. Analys av Nedbrytningsprodukter av Polymerer för Bitumenändamål

    Magister-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Björn Lindström; [2007]
    Nyckelord :Polymernedbrytning; SBS; Analys; RTFOT; PAV; GCMS; SPE;

    Sammanfattning : This project was aimed to study the degradation of polystyrene-butadiene-styrene block copolymer (SBS). SBS is used to modify bitumen, the binder in asphalt. From earlier studies it is known that SBS degrades in bitumen, but the degradation products have not been identified. LÄS MER
