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

    Författare :Zhuo Zheng; [2023]
    Nyckelord :Piezoelectric effect; metal-free; bio-organic material; γ-glycine; direct writing; energy harvester; Piezoelektrisk effekt; metallfritt; bioorganiskt material; γ -glycin; 3D-utskrift; energiskördare;

    Sammanfattning : The project is about piezoelectric energy harvesters and piezoelectric bio-organic materials.Nowadays, various kinds of energy harvesters based on micro or nano materials are appliedinmanyelectronic applications, such as wearable devices and electricity generators. LÄS MER

  3. 2. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Victor Eric Pierre Chartrain; [2023]
    Nyckelord :Cellulose; Paper; Plasticizer; Mechanical Refining; Cellulosa; Papper; Mjukgörare; mekanisk bearbetning;

    Sammanfattning : Fibers are interesting materials alternative to replace conventional fossil-based plastics, as they are bio-based and do not lead to CO2 emissions. Due to their limited ductility, it is difficult to use them to make complex three-dimensional shapes. LÄS MER

  4. 3. Anisotropic Muscle Phantoms for Shear Wave Elastography Assessment of the Levator Ani Muscle Properties

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Bleona Koxha; Melissa Jova Martinez; [2023]
    Nyckelord :pelvic floor disorder; levator ani muscle; shear wave elastography; phantom; anisotropy; polyvinyl alcohol; bäckenbottenbesvär; levator ani muskel; shear wave elastografi; fantom; anisotropi; polyvinylalkohol;

    Sammanfattning : Pelvic floor disorder is an emerging research area and is highlighted in many pelvic floor studies. Assessment methods for this type of injury are lacking and new methods for prevention and diagnosis are needed. Pelvic floor disorders are common among women and can lead to suffering for the patient. LÄS MER

  5. 4. Filtration of oil-in-water nanoemulsions for potential adjuvant development applications

    Master-uppsats, KTH/Kemiteknik

    Författare :Emilie Degeneve; [2023]
    Nyckelord :Filtration of oil-in-water nanoemulsions for potential adjuvant development applications; Vaccin; adjuvans; nanoemulsion; ytaktiva ämnen; filtrering;

    Sammanfattning : I den här studien undersöktes innovativa sammansättningar för produktion av vaccinadjuvans. Syftet var att stabilisera nanoemulsioner av olja i vatten, med hjälp av squalenolja (som används inom läkemedelsindustrin), med olika ytaktiva ämnen och att testa filtrerbarheten hos dessa nanoemulsioner.

  7. 5. The Use of Gels for the Removal of Cellulose Nitrate Lacquer on Silver

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Miri Katayon; [2022-07-05]
    Nyckelord :agar gel; metal conservation; nanomaterials; silver coating; sustainable conservation; varnish removal;

    Sammanfattning : The conservation of silver objects mainly constitutes addressing the issues of tarnish removal and of preventing tarnish. For decades lacquer has been used to coat silver objects in order to protect them from tarnishing. LÄS MER
