2. 1. 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

4. 2. Modeling of the wet-out process in composites manufacturing

   Author : Da Wu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process modeling; liquid composite molding; fiber preform deformation; free surface flow; porous media theory;

   Abstract : The fiber reinforced polymer composites (FRPCs) are carving out a niche amid the keen market competition to replace the other material counterparts, e.g., metals. Due to the low weight and corrosion resistance, the FRPCs are wildly utilized from aviation to automobile industries; both in the sectors of civilian and defense. READ MORE

5. 3. Flame-Retardant Cellulose Fibre/Fibril Based Materials via Layer-by-Layer Technique

   Author : Oruc Koklukaya; Lars Wågberg; Gero Decher; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flame-retardant; cellulose fibre; cellulose nanfibril; layer-by-layer technique; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : According to an analysis conducted by the Swedish Chemicals Inspectorate in 2006, the approximate numbers of fire injuries per year in Sweden are 100 deaths, 700 major and 700 minor injuries.1 Observations also show that there has been an increase in the number of house fires during recent years.

6. 4. Interactions between Polymers in Dispersion Coating and Surface Sizing of Paper and Board

   Author : Caisa Johansson; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

   Abstract : Barrier dispersion coatings are applied to paper or board in order to lower the permeability of the material to liquids and gases. In the present study, the film formation and barrier properties of latices used for coating applications were investigated. READ MORE

7. 5. 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
