  1. 1. Study of surfactant-preservative and protein-preservative interactions in multi-dose injectable formulation

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Javier Lagares Martín; [2023]
    Nyckelord :Phenol; polysorbate 80; cloud point; somatropin; aggregation; titration; light scattering; salt; surfactant; preservative; protein; tonicity adjusting agents; multi-dose injectable formulation; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : Multidose injectable formulations require a preservative such as phenol to ensure sterility and protection against microbial contamination during clinical use. However, it is known that the interaction between these components and non-ionic surfactants such as polysorbate 80, also found in this type of formulations, present incompatibilities, which can lead to decreases in the efficacy of the product.

  3. 2. Suzuki reactions in novel liquids

    Master-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Nazanin Hassanzadeh; [2021]
    Nyckelord :Suzuki coupling reaction; ni-DES; HPLC; TLC;

    Sammanfattning : Non-ionic deep eutectic solvent (ni-DES) possesses various advantages such as good solvation, biodegradability, and non-toxicity which makes it a perfect and environmentally friendly solvent for organic synthesis. A Pd (OAc)2 catalyzed, Suzuki reaction of aryl bromide and N-heteroaryl halide with arylboronic acid in green and novel solvent (ni-DES) is described. LÄS MER

  4. 3. Effect of filtration aid on downstream processing of polymer particles : Effektivisering av avvattningsprocessen av polymerpartiklar

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Emma Johansson; [2019]
    Nyckelord :;

    Sammanfattning : Polymer particles are expandable and produced by Nouryon. The production consists of polymerization, dewatering and drying. Dewatering of polymer particlesis an important part of the production process and have a large impact on how efficient the downstream process can be performed. LÄS MER

  5. 4. Polymeric single Li+-ion conductors: preparation and characterisation

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Hannes Nederstedt; [2016]
    Nyckelord :single ion conductors; electrolytes; polymers; lithium ion batteries; polymer technology; polymerteknologi; Chemistry; Technology and Engineering;

    Sammanfattning : Lithium-ion batteries are a common type of light-weight, rechargeable batteries. There are safety concerns because these batteries typically use an organic solvent electrolyte which presents fire hazards. By using dry polymer electrolytes, the fire hazards can be eliminated.

  7. 5. Estrogenic Substances in Plastic Bottles

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Frida Karlsson; [2014]
    Nyckelord :xenoostrogen; plastics; ER-Calux; Xenoöstrogen; Plast; ER-Calux; EEQ;

    Sammanfattning : We live in a time were plastic and plastic products are all around us, taking part in our everyday life. Several chemical additives can be present in plastic products, such as plastic bottles, and can have a big impact on development, as well as on the endocrine system in adults by the binding to, and disturbance of, the estrogen receptor (ER) in cells.
