  2. 21. Exploring Anaerobic Bacteria for Industrial Biotechnology - Diversity Studies, Screening and Biorefinery Applications

    Author : Rosa Aragao; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic bacteria; industrial biotechnology; biorefinery; microbial diversity; single cell entrapment; llama rumen;

    Abstract : Depletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. READ MORE

    Author : Karolin Axelsson; Jenny Lindh; Anna-Karin Borg-Karlson; Gunaratna Kuttuva Rajarao; Benedicte Albrectsen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Pine weevil; Hylobius; Rahnella; Pseudomonas; bacteria; fungi; metabolites; 2-methoxyphenol; 2-phenylethanol; Kemi; Chemistry;

    Abstract : The pine weevil (Hylobius abietis L.) is one of the two topmost economically important insect pests in Swedish conifer forests. The damage increase in areas were the silvicultural practice is to use clear cuttings were the insects gather and breed. READ MORE

  5. 23. Interactions of chiral ions and molecules in gas phase : Towards an understanding of chiral recognition mechanism

    Author : Oleksii Rebrov; Mats Larsson; Richard Thomas; Vitali Zhaunerchyk; Anne Zehnacker-Rentien; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Abstract : This thesis comprises the research related to interactions of enantiopure amino acids with chiral and achiral molecules in gas phase. The investigation of the mechanism responsible for chiral discrimination is of the special interest in this work. READ MORE

  6. 24. Nanofiber networks, aerogels and biocomposites based on nanofibrillated cellulose from wood

    Author : Houssine Sehaqui; Lars A. Berglund; Ton Peijs; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofibrillated cellulose; nanopaper; nanofiber; biocomposites; aerogel; foam; Materials science; Teknisk materialvetenskap;

    Abstract : Nanofibrillated cellulose (NFC) from wood is an interesting material constituent of high strength and high aspect ratio, which easily forms networks through interfibril secondary bonding including hydrogen bonds. This has been exploited in preparation of new materials, which extend the range of properties for existing cellulosic materials. READ MORE

  7. 25. Upgrading Cellulose Networks: Conquering Limitations in Fiber Foams

    Author : Eliott Jean Quentin Orzan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cross-linking; pore structure; cellular solid; lightweight; porous network; cellulose; flame-retardancy; fibers;

    Abstract : The battle to create structural materials with low environmental impact demands the investiture of two champions: porous structures and cellulose substrates. The dominant solutions when constructing strong lightweight materials are plastic and metallic foams, while currently, cellulose fiber foams suffer from challenges which hamper their development.
