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. Bläckborttagning från ben med hjälp av geler En kvantitativ studie för bläckborttagning på björnbäcken och björnkranium från Naturhistoriska riksmuseet

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Engla Nordin; [2023-11-07]
   Nyckelord :Conservation; reversibility; bones; FTIR; nanogels; hydrogels; ink.;

   Sammanfattning : This bachelor's thesis has investigated four different hydrogels loaded in different solvents efficiency to remove unknown ink from four pelvic bones and one skull from five bear individuals that belongs to The Swedish Museum of Natural History. The experimental part of the thesis consists of an FTIR analysis together with microscopy and macroscopy analysis of the ink on the bear skeletons, as well as some tests of different gel-solvent combinations on a moose skull.

4. 3. Decellularized ECM derived collagen bioinks

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för cell- och molekylärbiologi

   Författare :Matilda Carlson; [2023]
   Nyckelord :;

   Sammanfattning : 3D bioprinting allows for the manufacturing of tissue-like structures that could be used for culturing and studying cells in a microenvironment representative of the cell’s natural environment. In recent years, hydrogel bioinks from different biomaterials have been in development and utilized in tissue engineering applications. LÄS MER

5. 4. A viscoelastic evaluation of an injectable disulfide cross-linked thiol-collagen hydrogel: for tissue bulking post-myocardial infarction to prevent heart failure

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Makromolekylär kemi

   Författare :Karin Dungner; [2023]
   Nyckelord :;

   Sammanfattning : Cardiovascular diseases are currently the leading cause of death globally. Progression of the disease affects the composition and function of the heart and in many cases subsequently results in heart failure over time where a heart transplant is vital. Therefore, there is a need for medical treatments to stop the progression of the disease. LÄS MER

7. 5. Glyoxylic-Modified Lignin for Synthesis of Smart Elastomer and Composite Materials

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Xinyi Wei; [2023]
   Nyckelord :Lignin; lignin-based elastomer; nanocomposites; Lignin; ligninbaserad elastomer; nanokompositer;

   Sammanfattning : Sustainable development has become a global goal and the utilization of bioresources is a key way to achieve this crucial goal. Glyoxylic acid-functionalized lignin (GA-lignin) is one of the novel lignin derivatives extracted from beech wood (hardwood) and has great potential to be an industrially important bioresource.
