  2. 1. Multifunctional Carbon Foams by Emulsion Templating : Synthesis, Microstructure, and 3D Li-ion Microbatteries

    Author : Habtom Desta Asfaw; Kristina Edström; Leif Nyholm; John R. Owen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Battery; Carbon; Electrochemical; Electrodeposition; Emulsion; Energy; Exfoliation; Foam; Lithium; Microbattery; Multifunctional; Nanoparticles; Polyaniline; Polymer; Power; Sol-gel; Storage; Structured; Three-dimensional; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. READ MORE

  4. 2. Freeze-Dried Wheat Gluten-Based Foams

    Author : Thomas Blomfeldt; Mikael Hedenqvist; Delcour Jan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foams; Wheat gluten; Glutenin; Gliadin; Renewable; Freeze-drying; Pore structure; Baceterial cellulose; Glycerol; Mechanical properties; Thermal conductivity; Combustion properties;

    Abstract : This thesis presents wheat gluten foams as an alternative to the available commercialfoams. Polymeric foams, like all plastics, are mostly made from petroleum, and this isaffecting the environment negatively with the emission of greenhouse gases and generation oflandfills. READ MORE

  5. 3. Sustainable Biobased Protein Superabsorbents from Agricultural Co-Products

    Author : Antonio Jose Capezza; Mikael S. Hedenqvist; Eva Johansson; Antonio Guerrero; KTH; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; proteins; circularity; superabsorbents; sustainability; acylation; extrusion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The preparation of sustainable protein superabsorbents from agricultural industry side-streams is reported. Wheat gluten (WG), a co-product from the ethanol/starch industry, was processed into foams with sponge-like behavior and high liquid uptake. READ MORE

  6. 4. Bio-inspired cellulose nanocomposites and foams based on starch matrix

    Author : Anna Svagan; Lars A. Berglund; Salvatore Iannace; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; starch; cellulose nanofibers; foam; nanocomposites; cushioning materials; biodegradable; expanded polystyrene; mechanical properties; diffusion; Polymer chemistry; Polymerkemi;

    Abstract : In 2007 the production of expanded polystyrene (EPS) in the world was over 4 million tonnes and is expected to grow at 6 percent per year. With the increased concern about environmental protection, alternative biodegradable materials from renewable resources are of interest. READ MORE

  7. 5. Modeling of foams for impact simulations

    Author : Mats L Landervik; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Theory of Porous Media; Shell theory.; Constitutive modeling; Multiscale Analysis; Foams; Computational Homogenization;

    Abstract : Stimulated by the strong drive in the automotive industry to reduce energy consumption,and, linked to that, the need to reduce weight, this thesis concerns modeling of foams forimpact simulations. To start with, a continuum hyperelasto-viscoplastic model is developedwithin the framework of Theory of Porous Media. READ MORE
