  1. 1. Effect of Wood Constituents Oxidation of Unsaturated Fatty Acids

    Author : Alireza Salehi Movahed; Mats K.G. Johansson; Mats Johnssson; Karin Jacobsson; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

  2. 2. Thiol−ene Coupling of Renewable Monomers : at the forefront of bio-based polymeric materials

    Author : Mauro Claudino; Mats K. G. Johansson; Mats Jonsson; Anna Wistrand; Sven Göthe; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Thiol-ene chemistry; monounsaturated fatty-acids; renewable resources; cis trans-isomerization; photopolymerization; networks; polyesters; thermal viscoelastic properties; thin-films; unsaturated macro lactones; coatings;

    Abstract : Plant derived oils bear intrinsic double-bond functionality that can be utilized directly for the thiol–ene reaction. Although terminal unsaturations are far more reactive than internal ones, studies on the reversible addition of thiyl radicals to 1,2-disubstituted alkenes show that this is an important reaction.

  3. 3. Gluten Protein-Based Microcellular Foams and Composites: Development and Functional Properties

    Author : Thomas Blomfeldt; Mikael Hedenqvist; Mats K G Johansson; Lars Kloo; KTH; []
    Keywords : Wheat Gluten; Foam; Freeze-drying; Glycerol; Bacterial cellulose; Pore structure; Protein structure; Compression; Thermal conductivity; Combustion;

    Abstract : Most common foams are produced from non-renewable resources (e.g., synthetic plastics),with a number of environmental concerns, hence there is a demand for alternative bio-derivedfoam materials. Wheat gluten protein is widely known to have excellent foaming properties(e. READ MORE

  4. 4. Fabrication of polymeric microfluidic devices via photocurable liquid monomers

    Author : Klas Tommy Haraldsson; Mats K. G. Johansson; Ken Carter; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Photopolymerization; radical photopolymerization; polymerization kinetics; photoinitiation; vinyl ether; maleate; vinyloxy; Polymer chemistry; Polymerkemi;

    Abstract : Microfluidic devices have long been considered an ideal tool for rapid and inexpensive chemical analysis and reactions in areas ranging from point-of-care health to national security applications. However, fabricating microfluidic devices is time consuming, difficult and above all expensive. READ MORE

  5. 5. Protein-Based Adhesives for Particleboards

    Author : Sara Khosravi; Mats K. G. Johansson; Mikael Hedenqvist; Mikael Gällstedt; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Chemical engineering; Kemiteknik;

    Abstract : The main objective of this study was to elucidate the possibilities to use wheat gluten (WG) as a binder for particleboards, as well as soy protein isolate (SPI). The focus was on the effect of the adhesive formulation and the processing conditions, while the press parameters were kept constant. READ MORE
