  2. 1. Sustainable Biobased Protein Superabsorbents from Agricultural Co-Products

    Author : Antonio Jose Capezza; Mikael S. Hedenqvist; Eva Johansson; Antonio Guerrero; KTH; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; proteins; circularity; superabsorbents; sustainability; acylation; extrusion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The preparation of sustainable protein superabsorbents from agricultural industry side-streams is reported. Wheat gluten (WG), a co-product from the ethanol/starch industry, was processed into foams with sponge-like behavior and high liquid uptake. READ MORE

  4. 2. Computer Simulations of Polymer Gels : Structure, Dynamics, and Deformation

    Author : Natasha Kamerlin; Christer Elvingson; Jan Forsman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer simulations; Brownian dynamics; polymer gel; microgel; spherical boundary conditions; hypersphere; core-shell; deswelling; mechanical properties; uniaxial elongation;

    Abstract : This thesis presents the results of computer simulation studies of the structure, dynamics, and deformation of cross-linked polymer gels. Obtaining a fundamental understanding of the interrelation between the detailed structure and the properties of polymer gels is a challenge and a key issue towards designing materials for specific purposes.

    Abstract : Surface modification techniques have played important roles in various aspects of modern technology. They have been employed to improve substrates by altering surface physicochemical properties. READ MORE

  6. 4. Antibacterial materials for wound care applications utilizing antimicrobial peptides

    Author : Edvin Blomstrand; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; self-assembly; lyotropic liquid crystals; antibacterial surface; Antimicrobial peptides; Pluronic F-127; hydrogels;

    Abstract : The spread of antibiotic resistance among bacteria has shown that the development of alternative treatments of infections is of vital importance. This thesis has looked at one potential candidate, antimicrobial peptides (AMPs), as an alternative or compliment to traditional antibiotics. READ MORE

  7. 5. Rheological and mechanical properties of systems containing nanocellulose

    Author : Tobias Moberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shear rheology; Cellulose nanocrystals; Cellulose nanofibrils; Mechanical properties; Dynamic-mechanical analysis; Composites; Extensional rheology;

    Abstract : Nanocellulose is a cellulose entity at the nanoscale. There are several different types of nanocellulose such as cellulose nanofibrils (CNF), which are long, somewhat flexible fibrils and cellulose nanocrystals (CNC), which are shorter and more rod-like particles. READ MORE
