  1. 1. Plasticization of Biobased Polymers: A Combined Experimental and Simulation Approach

    Författare :Hüsamettin Deniz Özeren; Mikael S. Hedenqvist; Richard Olsson; Fritjof Nilsson; Kim Bolton; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasticization; starch; gluten; simulation; molecular dynamics; glycerol; mjukgörning; stärkelse; gluten; simulering; molekyldynamik; glycerol; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : 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. LÄS MER

  3. 2. Effects of carbon dioxide and ozone on wheat crop yield and grain quality

    Författare :Malin Broberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; koldioxid; ozon; vete; skörd; protein; stärkelse;

    Sammanfattning : 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. LÄS MER

  4. 3. Characterisation of starch: development of analytical methods

    Författare :Gunilla Nilsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; substitution pattern; microdialysis; HPAEC-PAD; NMR; biosensor; IMER; potato amylopectin starch; amylose; amylopectin; chain length; Analytical chemistry; Analytisk kemi;

    Sammanfattning : 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. LÄS MER

  5. 4. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry

    Författare :Arieh Cohen; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ESI-MS; Polysaccharides; Hydrolysis; Cellulases; Starch Hydrolases; Enzymatic Degradation; Enzymes; Substituent Distribution; Modified Cellulose; Mass Spectrometry; Modified Starch; Analytical chemistry; Analytisk kemi; HPAEC-PAD;

    Sammanfattning : 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. LÄS MER

  7. 5. Polyelectrolyte multilayers of cationic and anionic starch and their use for improving the strength of papers made from mechanical pulps

    Författare :Lisa Lundström; Lars Wågberg; Mats Johansson; Per Engstrand; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : 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. LÄS MER
