1. 1. Thermoset biopolymer reinforced with carbon-nanotubes

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Morteza Esmaeili; [2019]
   Keywords : biopolymers; bio-composites; glycerol lactic acid; carbon nanotube; reinforcement; thermoset; dispersion;

   Abstract : Compared to conventional fibers, carbon nanotubes possess several significant properties, which make them as an excellent alternative reinforcement in multi-functional material industry. In this study, the possibility of dispersion of the multi-wall carbon nanotube (MWCNTs) in a thermoset bio-based resin (synthesized based on end-functionalized glycerol-lactic acid oligomers, GLA, at university of Borås) was investigated.

3. 2. Biodegradation and ageing of bio-based thermosetting resins from lactic acid

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Lara Lopes Gomes Hastenreiter; [2019]
   Keywords : bio-based polymer; lactic acid; glycerol; ethylene glycol; pentaerythritol; biodegradation; ageing; characterisation; DSC; TGA; FTIR; tensile;

   Abstract : The need for replacing petroleum-based polymers has been increasing and bio-based polymers prove to be a suitable solution. The aim of this thesis was to synthesize bio-based resins with different chemical architectures to evaluate the effect of the structure on the properties and on their response to ageing and biodegradation.

4. 3. Att bedöma hygienisk kvalitet i grovfoder för hästar

   University essay from SLU/Dept. of Animal Nutrition and Management

   Author : Mikaela Würtz; [2017]
   Keywords : bakterier; jäst; LPS; mykotoxiner; mögel;

   Abstract : Denna litteraturstudie behandlar ett urval av metoder för att bedöma hygienisk kvalitet i grovfoder för hästar. Mikrobiella och makroskopiska undersökningar tas upp såväl som hur innehållet av mykotoxiner och lipopolysackarider (LPS) i grovfoder kan analyseras. READ MORE

5. 4. Eco Friendly Composites Prepared from Lactic Acid Based Resin and Natural Fiber

   University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

   Author : Nima Esmaeili; Shahrzad Javanshir; [2014]
   Keywords : Biobased thermoset; thermoset poly lactic acid; biobased composite; natural fiber; viscose;

   Abstract : Lactic acid based thermoset were synthesised by reacting lactic acid with glycerol andfunctionalizing lactic acid branches by methacrylic anhydride. Resins with different chainlength were prepared and their thermo mechanical properties were examined through DMAanalysis and their molecular structures were analyzed by NMR method and their viscositywere investigated through rheometry analysis and three monomers were selected as the bestchain length.
