1. 1. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

   University essay from KTH/Fiber- och polymerteknologi

   Author : Felix Bogdan; [2023]
   Keywords : Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

   Abstract : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. READ MORE

3. 2. Tuning physical and chemical attributes of the synthetic implant poly(L-lactic acid) and its effects on biological stimulation

   University essay from

   Author : Gabriella Sverlinger; Felicia Norman; Nora Othman; Wilma Hämäläinen; Michaela Thyberg; Maja Jonsson; [2023]
   Keywords : Polylactic acid; degradation rate of PLLA; physio- chemical properties of PLA; injectable PLLA;

   Abstract : Poly(lactic acid) (PLA) is a polymer chain consisting of repeating units of lactic acid (LA) used in various biomedical applications because of its biocompatible features. It is commonly used as a subdermal filler and constitutes as the main ingredient in SculptraR, which is a collagen regenerating filler used to treat lipoatrophy of the cheeks or to rejuvenate the skin.

4. 3. Evaluation of using bioplastics for lab consumables

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Lovisa Mäepea Nilsson; Emelie Gunnarsson; Sara Mardini; Fartun Nuur Yusuf; Jesper Nyström; [2022]
   Keywords : bioplastics; Biotage; sustainability; green washing; biopolymers; PLA; bio-based; environment; PHA; PP; PE; chemical properties; bioplaster; hållbarhet; bio-polymerer; bio-baserad; miljövänlig;

   Abstract : The use of plastic has increased markedly in recent years which has led to more fossil fuels being used and more plastic in nature. This is a literature study that researches on how bio- based plastics can be used instead of plastics made from fossil fuels. READ MORE

5. 4. Optimizing Growth Conditions for Lactic Acid Bacteria

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Lorenzo García Tejada; [2021]
   Keywords : Lactic Acid Bacteria; Optimization; Cell growth; Lactic acid production; Oxygen; Yeast extract; Wood hydrolysate; Poly-lactic acid; Chemical engineering; Technology and Engineering;

   Abstract : High production titers are paramount in lactic fermentation processes aimed towards poly lactic acid (PLA) manufacturing. Optimization of the fermentation stage is therefore essential for the viability of the process. READ MORE

6. 5. Development of polymer based composite filaments for 3D printing

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Elin Åkerlund; [2019]
   Keywords : 3D-printing; fused deposition modeling FDM ; composite filaments; biocompatible materials; biodegradability; medical applications; scaffold materials; poly lactic acid PLA ; polycaprolactone PCL ; hydroxyapatite HA ; mechanical properties; thermal stability; chemical composition; morphological characterization; accelerated degradation study; polymer degradation behavior;

   Abstract : The relatively new and still growing field of 3D-printing has opened up the possibilities to manufacture patient-specific medical devices with high geometrical accuracy in a precise and quick manner. Additionally, biocompatible materials are a demand for all medical applications while biodegradability is of importance when developing scaffolds for tissue growth for instance. READ MORE
