  1. 6. Deacetylated Hyaluronan : Exploration of deacetylation techniques for hyaluronan (oligo and polysaccharides)

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Sima Mardini; Hanna Björk; Marcus Möller; Carl Lagergren; Oscar Samuelsson; [2023]
    Nyckelord :hyaluronic acid; deacetylated hyaluronan; N-deacetylation; re-acetylation; hydrogels;

    Sammanfattning : Hyaluronic acid is an organic polysaccharide with a wide range of uses in medical and cosmetic industries due to its physiological properties. Crosslinked hyaluronic acid is a commonly used filler agent because of its water retention capabilities. N-deacetylation can be performed to enable new derivatives of hyaluronic acid. LÄS MER

  3. 7. Green Protein Hydrogels and Non-dry Aerogels in Water Purification

    Kandidat-uppsats, KTH/Kemi

    Författare :Emanuel Nelsson Vedung; Alexander Singh; Julia Wadefjord; [2022]
    Nyckelord :Aerogel; Hydrogel; Whey Protein Isolate; Water purification; Adsorption; Sustainability;

    Sammanfattning : Having access to clean water is not a certainty for every human being. Today, there are major problems with polluted water that not just affect us humans, but also the ecosystem around us. In recent years, research into making aerogels from protein nanofibrils (PNF) has increased. LÄS MER

  4. 8. Exploration of bioactive additives for hyaluronan based hydrogels : A literature study

    Kandidat-uppsats,

    Författare :Tilda Eriksson; Lisa Quakkelaar; Alexander Parkstam; Alina Karlsson; Mansourah Askari; Shukri Said Ahmed; [2022]
    Nyckelord :Hyaluronan; Hyaluronic Acid; HA; 1; 4-Butanediol diglycidyl ether; BDDE; polynucleotides; mannitol; biomedical applications; dermatological fillers; fillers; Hyaluronan; Hyaluronsyra; HA; 1; 4-butandiol diglycidyleter; BDDE; polynukleotider; mannitol; biomedicinska applikationer; dermatologiska fyllmedel; fyllmedel;

    Sammanfattning : Hyaluronan (HA) is a substance that is commonly used in biomedical applications in the form of hydrogels. One of these biomedical applications is dermatological fillers where HA is cross-linked with 1,4-Butanediol diglycidyl ether (BDDE) to reduce its rapid turnover within tissue. The filler gives a volumetric effect that can fill out wrinkles. LÄS MER

  5. 9. Hyaluronic Acid Hydrogel as a Scaffold for Cells’ Encapsulation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Susanna Wärmegård; [2022]
    Nyckelord :hyaluronic acid; hydrogel; 3D cell culture;

    Sammanfattning : Hydrogels are high water-content polymers that mimic the extracellular matrix of cells. The polymers can have many sources and be of natural origin from the extracellular matrix (ECM) of cells or be synthetically derived. LÄS MER

  7. 10. Cleaning Research for 18th century Unvarnished Water-sensitive Matte Tempera Paint

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Anastasiya Serdyukova; [2021-11-03]
    Nyckelord :Conservation; Water-Sensitive; Matte Tempera; Hydrogels;

    Sammanfattning : This master thesis studies various cleaning techniques used to conserve the unvarnished matte tempera painted surfaces of the Per Stålhammar funeral coat of arms for the Kalmar Läns museum (KLM 014946). The polychrome sculpture is dated from 1701 and has never been conserved before. LÄS MER
