  1. 21. Polymer Directed Engineering of Novel Cellulose Network

    University essay from KTH/Fiber- och polymerteknologi

    Author : Christel Gradin; Adina Landström; Julia Szecsödy; [2021]
    Keywords : Hydrogel; Carboxylated CNF; TEMPO-oxidation; bis-MPA ammonium dendrimer; Polymer salt bridge; Rheology;

    Abstract : This study investigated a CNF/dendrimer hydrogel and how different concentrations of the carboxylated CNF and bis-MPA ammonium dendrimer affected the hydrogels’ rheological properties. A third generation bis-MPA ammonium dendrimer was diffused into a dispersion of carboxylated cellulose nanofibrils. READ MORE

  3. 22. 3D Bioprinting Meniscus for Future Tissue Replacement in Osteoarthritis Affected Knee Joints

    University essay from

    Author : Ida Pettersson; Amanda Olsson Widjaja; [2020-06-22T09:59:20Z 2020-06-22T09:59:20Z 2020 2019]
    Keywords : Alginate; Articular Cartilage; Bioink; Induced Pluripotent Stem Cells; Meniscus; Nanofibrillated Cellulose; Osteoarthritis; Screening; 3D Bioprinting;

    Abstract : Progressive cartilage defects in human knee joints are a worldwide health issue that exposes a great burden on society as well as on single individuals. Sudden traumas to the knees can induce tears in the structures of the joints such as the articular cartilage and the meniscus. READ MORE

  4. 23. Approaches for improving the rheological characterization of fermented dairy products

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Abdulrahman Muhammad; [2020]
    Keywords : food engineering; livsmedelsteknik; Technology and Engineering;

    Abstract : Fermented dairy products are wildly consumable products in today societies, and these products are known for their unique rheological properties due to the complex structural systems they possess. The simplest rheological model for describing yogurt behavior is the Power Law model, but this model parameters are not sufficient for describing the complex behavior during flow and filling.

  5. 24. Method development for rheological characterization of microfibrillated cellulose

    University essay from Karlstads universitet

    Author : Elin Wahlkrantz; [2020]
    Keywords : microfibrillated cellulose; MFC; rheology; characterization; dynamic rotational rheometer; complex viscosity; amplitude sweep; dry content; pH; conductivity; measuring geometry; gel; mikrofibrillerad cellulosa; MFC; reologi; karakterisering; dynamisk rotationsreometer; komplex viskositet; amplitudsvep; torrhalt; pH; konduktivitet; mätgeometri; gel;

    Abstract : This thesis contributes to a development of a method for rheological characterization of microfibrillated cellulose. The intended use of the method is to be able to distinguish between different grades of microfibrillated cellulose. READ MORE

  6. 25. Quality of fermented dairy products beyond best before date

    University essay from SLU/Department of Molecular Sciences

    Author : Therese Holmsten; [2020]
    Keywords : yoghurt; sour milk; date labelling; rheology; microbiological plating method; Pivot Profile;

    Abstract : Date labelling is one factor influencing food waste in consumer households and evaluation of optimum shelf life is a tool food industry can use to contribute to di-minished food waste. This explorative pilot study aimed to investigate how quality of sour milk and yogurt changed beyond best before date. READ MORE
