1. Plasticization of Biobased Polymers: A Combined Experimental and Simulation Approach
Abstract : The field of bio-based plastics has developed significantly in recent decades and there is an increasing demand for industries to shift from petrochemical to biobased polymers. Biobased polymers offer competitive properties, and in many cases have advantages in terms of cost. READ MORE

2. Effects of carbon dioxide and ozone on wheat crop yield and grain quality
Abstract : Atmospheric concentrations of carbon dioxide (CO2) and ozone (O3) have steadily increased since the industrial revolution. CO2 and O3 directly affect plant physiology, CO2 being an essential substrate for photosynthesis, while O3 is an oxidative agent causing damage to plant tissues. READ MORE

3. Characterisation of starch: development of analytical methods
Abstract : Starch, comprised of amylose and amylopectin, is a very complex biopolymer. Different methods are therefore needed for the investigation of the molecular structures of amylose and amylopectin. In this thesis analytical methods have been developed and various techniques were combined for the characterisation of starch. READ MORE

4. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry
Abstract : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. READ MORE

5. Polyelectrolyte multilayers of cationic and anionic starch and their use for improving the strength of papers made from mechanical pulps
Abstract : Graphic paper is experiencing severe competition from other materials and, most of all, from other media. This means there is a great need to improve paper quality while reducing raw material and production costs. Polyelectrolyte multilayer (PEM) treatment (i.e. READ MORE
