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

   University essay from Uppsala universitet/Institutionen för materialvetenskap

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

   Abstract : 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. READ MORE

3. 2. Epigenetic Profiling of Canine Brain

   University essay from KTH/Proteinvetenskap

   Author : Roxanne Carlsson Norlin; [2022]
   Keywords : Dog; wolf; evolution; HiCap; enhancers; Hund; varg; evolution; HiCap; enhancers;

   Abstract : Hundens domesticering är en av de äldsta och tros ha startats 35000 f.n. Under domesticeringen från varg till hund, har hunden utvecklat både morfologiska och beteendemässiga skillnader så som bredare snot, högre skallar och minskat risktagande. READ MORE

4. 3. Injectable and shape-retaining collagen hydrogel, crosslinked using bio-orthogonal cycloaddition chemistry

   University essay from KTH/Fiber- och polymerteknologi

   Author : Murtaza Sharq; [2022]
   Keywords : Injectable and shape-retaining collagen hydrogel; crosslinked using bio-orthogonal cycloaddition chemistry; Injicerbara och formbevarande kollagenhydrogeler; tvärbundna med bio-ortagonal cykloadditionskemi;

   Abstract : Under senaste decennierna, har intresset kring implantat från naturliga och syntetiska polymerer ökat markant i samband med en ökad marknadsefterfrågan på vävnadsdonationer. Detta har lett till efterforskningen av nya in-situ formerande geler med formbevarande egenskaper in-vivo. READ MORE

5. 4. Synthesis and Investigation of Nitrile-Containing Polymers Inspired by Lignin

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Tobias Lindborg; [2022]
   Keywords : Lignin; Polymer; Renewable; Bioresource; Glass transition temperature; Nitrile; Polymer technology; Chemistry; Technology and Engineering;

   Abstract : The lignin-inspired derivatives coniferyl aldehyde and sinapyl aldehyde were used to prepare nitrile-containing methacrylate monomers with the aim to synthesize bio-based polymers exhibiting high glass transition temperatures (Tgs). The aldehydes were initially transformed to the corresponding nitriles and then underwent methacrylation before being polymerised by free-radical polymerisation. READ MORE

6. 5. Crosslinked Cartonboard - Challenges and possibilities

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Malin Elvin; [2022]
   Keywords : Cartonboard; crosslinking; mechanical properties; SCT;

   Abstract : The need for sustainable packaging is growing, and plastic waste needs to be reduced. A suitable alternative could be fibre-based packaging and cartonboard, and several actions could enhance this alternative. This study investigates crosslinking, a method to create stronger bonds between the OH-groups in the material. READ MORE
