  2. 1. 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

  4. 2. Effect of Wood Constituents Oxidation of Unsaturated Fatty Acids

    Author : Alireza Salehi Movahed; Mats K.G. Johansson; Mats Johnssson; Karin Jacobsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wood constituents; oil; oxidation; unstatured fatty acids; lignin; model lignin compounds; Polymer chemistry; Polymerkemi;

    Abstract : This work presents the mechanisms of free radicals in a model system between fatty acids oxidation process and wood components. The aim is to create a better understanding of new environmentally friendly materials for exterior wood protection. READ MORE

  5. 3. Dried nanofibrillated cellulose and its bionanocomposites

    Author : Christian Eyholzer; Olli Ikkala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Abstract : During the past decade there has been a growing interest in the reinforcement of synthetic polymers with cellulose nanowhiskers and nanofibrillated cellulose (NFC) obtained from plants or bacteria. Their beneficial mechanical properties like high stiffness and strength, in combination with their low mass allowed successful reinforcement of water based polymer dispersions (latexes) for the production of solution cast composite films.

  6. 4. Interaction of sound waves with a swirl stabilized wood powder flame and their effects on flame characteristics

    Author : Burak Göktepe; Henrik Wiinnika; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Swirling flows have been widely used for many years in engineering applications such as; chemical and mechanical mixing devices, separation units, spray drying technologies, turbo machinery and combustion systems. In practical combustion applications, swirl motion has been adopted to the incoming reactant flows in order to enhance the mixing of fuel and oxidizer and to improve flame stabilization and establishment, especially in regions of relatively low velocities, by recirculating hot product gas to the incoming reactants.
