16. Viscoelastic properties and plasticization potential of native, residual, and technical lignin
Sammanfattning : Lignin in biomass, pulp, and isolated during pulping all have great potential as renewable and inexpensive thermoplastic components and materials, but widespread utilization is hindered by high glass transition temperatures (Tg), brittleness, and poor flow properties. The aim of this thesis is to elucidate what molecular structures govern lignin thermoplasticity and how these can be efficiently manipulated. LÄS MER
17. Edible and Biodegradable Whey Protein Films as Barriers in Foods and Food Packaging
Sammanfattning : This thesis focuses on the characterization of whey protein films. The films were cast from heated aqueous solutions and dried in a climate room at 23 °C and 50% relative humidity for 16 h. The microstructure of the films was found to be dependent on the protein concentration, the plasticizers, and the pH. LÄS MER
18. Dynamics of Biomembranes and Rheological Properties of Living Cells
Sammanfattning : An ingenious assembly of biomolecules and water constitute what we call biological tissue. The presence of water in this assembly is fundamental for the physiological processes and can make the difference between life and death. LÄS MER
19. Material Properties of Starch and Cereal Protein Films and Foams
Sammanfattning : Materials that are renewable and biodegradable are demanded for environmental reasons. Biopolymeric materials, such as materials from starch and cereal proteins, are both renewable and biodegradable. However, starch and cereal protein materials are generally rather brittle and therefore need to be plasticized to become more flexible. LÄS MER
