11. Biofoams and Biocomposites based on Wheat Gluten Proteins
Abstract : Novel uses of wheat gluten (WG) proteins, obtained e.g. as a coproduct from bio-ethanol production, are presented in this thesis. A flame-retardant foam was prepared via in-situ polymerization of hydrolyzed tetraethyl orthosilicate (TEOS) in a denatured WG matrix (Paper I). READ MORE

12. Early Hydration of Portland Cement
Abstract : The production of cement is responsible forapproximately 7 % of the total CO2 emissions caused by man. To compensate for high energyconsumption and CO2 emission, thus making the utilization of concrete more sustainable,several strategies can be used. READ MORE

14. Physiology of Industrially Relevant Bacteria: Freeze-drying tolerance of Lactobacillus reuteri and Pseudomonas chlororaphis and product formation of Lactococcus lactis metabolizing maltose
Abstract : When the metabolic activity of bacteria is exploited by the food and biotechnology industries, freeze-drying is commonly used to produce concentrated bacterial cultures with enhanced storage stability. The freeze-drying tolerance of the probiotic strain Lactobacillus reuteri and the biocontrol agent Pseudomonas chlororaphis has been characterized in this work. READ MORE

15. Porous Cellulose Materials from Nano Fibrillated Cellulose
Abstract : In the first part of this work a novel type of low-density, sponge-like material for the separation of mixtures of oil and water has been prepared by vapour deposition of hydrophobic silanes on ultra-porous nanocellulose aerogels. To achieve this, a highly porous (> 99 %) nanocellulose aerogel with high structural flexibility and robustness is first formed by freeze-drying an aqueous dispersion of the nanocellulose. READ MORE
