  1. 6. Acoustic Characterization of the Cellulose-coated Perfluorocarbon Droplets based on Phase Velocity Measurements

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Emma Lindroth; [2020]
    Nyckelord :Ultrasound; Droplets; Contrast agent; Cellulose; Perfluorocarbon; Acoustic characterization; Non-destructive evaluation; Phase velocity; Bulk modulus; Compressibility;

    Sammanfattning : Today, microbubbles are one of the most commonly used ultrasound contrast agents, since their high compressibility results in a strongly scattered signal. Despite this advantage, microbubbles experience limitations by the decreased stability and large diameter. LÄS MER

  3. 7. Acoustic Characterization of the Frequency-Dependent Attenuation Profile of Cellulose Stabilized Perfluorocarbon Droplets

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Lisa Saljén; [2020]
    Nyckelord :Ultrasound; Contrast Agent; Attenuation; Acoustic Characterization; Non Destructive Evaluation; Perfluorocarbon; Droplet; Cellulose; Oscillation; Acoustic Droplet Vaporization;

    Sammanfattning : The use of ultrasound contrast agents increases the information available for reconstruction during ultrasound imaging. Previously studied microbubbles, consisting of a gas core, are subject to limitations such as a short lifetime and a large size. LÄS MER

  4. 8. Mechanical properties of films made of faba bean protein nanofiber and non-fibrillated protein

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Alice Dunge; [2019]
    Nyckelord :Faba bean; amyloid; fibrils; meat substitutes; elasticity; stiffness; proteins;

    Sammanfattning : The production of livestock puts a huge strain on our ecosystem and the planet. It is the largest source of greenhouse gases and it causes loss in biodi-versity and pollution of water. One way to reduce these environmental dam-ages is to decrease the intake of meat and increase the intake of plant-based proteins. LÄS MER

  5. 9. Framställning av nanocellulosa och påverkan av råmaterialet

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

    Författare :Viktor Bladholm; Adam Britts; Alexandra Edberg; Anmol Khawaja; [2016]
    Nyckelord :Nanocellulosa; Framställning; Råmaterial; Kemisk sammansättning; Karakterisering;

    Sammanfattning : Den här rapporten behandlar framställning av nanocellulosa, CNF, och hur det kemiska innehållet för barr- respektive lövmassa påverkar framställningen. De massor som använts i undersökningen var båda ursprungligen från oblekta sulfatmassor. LÄS MER

  7. 10. NANOMATERIALS FOR THE DECONTAMINATION OF WASTE WATER CONTAINING PHARMACEUTICAL DRUGS

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Joydip Paul; [2015]
    Nyckelord :;

    Sammanfattning : The existent of pharmaceutical drugs in our aquatic media is a preeminent burden for the environment effect including health fitness issues. The presence of tiny amount of organic and inorganic pharmaceutical drugs including hormones, birth control pills, NSAID, antibodies can causes a huge destruction for our living entity now a days.
