  1. 1. BORTTAGNING AV TRYCKKÄNSLIG TEJP PÅ PAPPER En studie över användningen av hydrogeler

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Amanda Nyagake Mwita; [2023-11-07]
    Nyckelord :Pressure-sensitive tape; agar-gel; hydrogel; nanogel; paper conservation;

    Sammanfattning : The purpose of this thesis is to examine hydrogels practical efficiency in the removal of pressure-sensitive tapes on paper. The organic agar gel and synthetically produced Nanorestore Gel® PG5 Peggy Gel and Nanorestore Gel® High Water Retention are used in an experimental process upon removing three common pressure-sensitive tapes (PTSs) on paper.

  3. 2. Production of textile fibres from filamentous fungi grown on apple pomace : invertase pre-treatment

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Sofia Berg; [2023]
    Nyckelord :apple pomace; invertase; fibres; filamentous fungi; dry gel spinning;

    Sammanfattning : In this work Rhizopus Delemar was grown on an apple pomace medium, a waste product from the juice industry. The apple pomace was pre-treated with the enzyme invertase to hydrolyse the sucrose available in the waste to glucose and fructose, which are digestible by the fungus. LÄS MER

  4. 3. Navmark - ett nytt sätt att rädda liv

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Ida Stjärnborg; Lina Torkelsson; [2023]
    Nyckelord :;

    Sammanfattning : Cancer is a tough disease and in some cases is difficult to treat, which leads to too many people dying. Of the cancer diagnoses made each year, 3.2 million of these are primary and secondary liver cancer. The world needs to be able to reduce these tragic outcomes and to be able to remove a liver tumor in a more patient-centered way. LÄS MER

  5. 4. Protein-based hydrogel electrolytes for stretchable Zn-ion batteries

    Master-uppsats, Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Författare :Lovisa Byström; [2023]
    Nyckelord :Hydrogel; gelatin; kappa-carrangeenan; Zn-ion battery; Kemisk biologi; Kemisk biologi;

    Sammanfattning : Stretchable aqueous-based Zn-ion batteries have shown promise as a sustainable and safe energy storage system for wearable electronics used in healthcare, sports, soft robotics, and prosthetics. A battery consists of the active electrode, electrolyte, current collector, and encapsulation. LÄS MER

  7. 5. 3D Printing Hydrogel Artificial Muscles and Microrobotics

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Malin Alterby; Emily Johnson; Anton Jonason; Denize Svensson; [2023]
    Nyckelord :3D printing; MXene; CNT; CNF; hydrogel; actuator;

    Sammanfattning : The purpose of this lab was to investigate the printability of cellulose nanofiber/carbon nanotubes, their functions as actuators, and to compare these properties with MXene/nano cellulose gels. Data on MXene/nano cellulose gel was obtained from previous research made by Hamedi labs. LÄS MER
