12. Strategies to improve the aging, barrier and mechanical properties of chitosan, whey and wheat gluten protein films
Sammanfattning : 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. LÄS MER
13. Design of Functional Polymeric Nanoparticles for Biomedical Applications
Sammanfattning : Most of the devastating diseases such as cancer are relatively incurable and have high risks of relapse. Therefore, persistent endeavors have been devoted to improve patient survival rate and quality of life. LÄS MER
14. Revealing the potential of Nordic microalgae : turning waste streams into resources
Sammanfattning : As the world's population grows, the demand for fresh water, food, fuel, energy and modern technology increases tremendously. Not only does this require enormous amounts of resources but it also increases the amount of waste and especially wastewater. LÄS MER
15. Synthesis of Biomedical Polymers and Scaffold Design
Sammanfattning : This work has focused on the development of new improved synthesis methods of biodegradable aliphatic polymers and on the preparation of porous scaffolds for tissue engineering applications. The aim of the first part of the work was the synthesis of poly(p-dioxanone) (PPDX) homopolymers with high molecular weights using the cyclic tin alkoxide initiator 1-di-n-butyl-1-stanna-2,5-dioxacyclopentane.
