  1. 11. 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. 12. Negative energy elasticity and a model for the behavior of the residual strain in doubly cross-linked gels fabricated by shear strain

    University essay from Uppsala universitet/Polymerkemi

    Author : Therese You; [2020]
    Keywords : Polymer gel; Tetra-PEG; hydrogels; doubly cross-linked gels; shear modulus; energy elasticity;

    Abstract : Doubly cross-linked gels were fabricated based on tetra-poly(ethylene glycol) (Tetra-PEG) by shear strain. These are gels with two network structures present in the same polymeric network. The second network structure is introduced by applying a mechanical field to the first natural network structure.

  4. 13. Tuning the crosslinking chemistry for self-healable mucin hydrogel synthesis and application

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Francesca Pacella; [2020]
    Keywords : Mucin; Hydrogel; Click-chemistry; Characterization; Self-healing; Injectable; Hydrogeler; Mucin; självhelande;

    Abstract : Immune-orchestrating biomaterials that precisely modulate the immune reac-tion to the host could lead the way for improving the implantation outcomein the transplantation field, in comparison to passive biomaterials. The lab-oratory of Dr. READ MORE

  5. 14. Comparison of Corn and Rye Arabinoxylans for the Production of Bio-based Materials

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Chen Chen; [2020]
    Keywords : cereal bran; subcritical water extraction; arabinoxylans; enzymatic crosslinking; hydrogel; spannmålskli; extraktion av subkritiskt vatten; arabinoxylaner; enzymatisk tvärbindning; hydrogel;

    Abstract : Enzymes and subcritical water can be used for the extraction of hemicelluloses from cereal by-products, making the processes eco-friendly. The polysaccharides extracted from cereal by-products can be used as matrices for development of materials for various applications. READ MORE

  6. 15. Design, evaluation and use of a microfluidic device for automated production of mucin microparticles for cell encapsulation for diabetes therapy

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Bharathesh Badadamath; [2019]
    Keywords : ;

    Abstract : Droplet microfluidics has prevalent growth in a wide range of applications in the life science field. This project is one such example where we used a droplet microfluidics tool for treating diabetes mellitus type 1. Mucin hydrogels (Muc-gels) modulate the immune response driving biomaterialinduced fibrosis.[1]. READ MORE
