1. Design of Cellulose-based Materials by Supramolecular Assemblies
Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

2. Strategies for Renewable Barriers with Enhanced Performance
Abstract : Forest biomass is expected to play an increasingly important role in tomorrow´s global bio-economy as one of the main renewable sources of materials, chemicals and energy. In the framework of the biorefinery concept, the forestry industry is looking for new processes to utilize several fractions in the biomass (cellulose, hemicelluloses, lignin etc. READ MORE

3. Strategies to improve the aging, barrier and mechanical properties of chitosan, whey and wheat gluten protein films
Abstract : Chitosan, Whey Protein Isolate (WPI) and vital wheat gluten (WG) are three biomaterials that have quite promising properties for packaging purposes. They have good film forming properties and good gas barrier properties in dry conditions. READ MORE

5. Edible and Biodegradable Whey Protein Films as Barriers in Foods and Food Packaging
Abstract : 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. READ MORE
