  1. 1. Synthesis and characterization of lactic acid-based elastomers

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Afsaneh Makhdoumi; [2023]
    Nyckelord :Lactic acid; Elastomer; Bio-based elastomer; Renewable resource;

    Sammanfattning : Synthesized polymer from bio-based and renewable resources reported as an attractive substitution for fossil-fuel based polymers. Therefore, this work has focused on using sustainable material for production of elastomers to reduce the environmental impact of fossil-based elastomers and overcome the shortage of non-renewable fuels.

  3. 2. 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

  4. 3. Development Of Bio-Based Thermosetting Resins

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Snehaben Gaurangkumar Mistry; [2021]
    Nyckelord :Bio-based polymer; Resin; lactide; lactone; isosorbide; butanediol; polymerisation; characterisation; FTIR; NMR; TGA; DMA;

    Sammanfattning : Thermoset polymers are widely used polymers in the world, but Increase in global plastic pollution and lack of fossil fuel stimulates intense research towards environmentally sustainable materials. Bio-based unsaturated polyesters (UPs) would be an excellent solution to replace oil-based synthetic polyesters. LÄS MER

  5. 4. The effect of silage quality on gross energy losses

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Irfan Sakhawat; [2011]
    Nyckelord :Additive; Clostridia; Fermentation; Lactic acid bacteria; Losses;

    Sammanfattning : Silage is a feed for ruminants resulting in the preservation of fresh forage crops by acidification, which is achieved under anaerobic environment. The process of ensiling is mainly depends upon the chemical and microbial composition of forage. LÄS MER

  7. 5. Lättlösliga kolhydrater i vallfoder och i hästens grovtarm

    L3-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Sofia Fridh; [2007]
    Nyckelord :lättlösliga kolhydrater; digestion; vallfoder; häst; kolon;

    Sammanfattning : The purpose of this study was to investigate how the content of glucose, fructose, sucrose and fructan (WSC) varied in silage, haylage and hay harvested from the same field and at the same time of harvest. The study also investigated if differences in the WSC-fraction in the forages caused differences in composition of WSC in the colon of horses fed the forages. LÄS MER
