  1. 1. Graphene Oxide Technology to Advance the Performance of Poly(lactic acid) Materials

    Author : Huan Xu; Minna Hakkarainen; Jean-Marie Raquez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Poly lactic acid ; Graphene Oxide; Stereocomplex; Nucleation Mechanism; Crystalline Morphology; Filler Structure; Mechanical Properties; Gas Barrier; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : In the past two decades, a burgeoning biorefinery concept has grown in concert with the materials science, contributing to the rise of biobased materials that respect environment and are versatile for various applications. An excellent example is poly(lactic acid) (PLA) that exhibits high strength and desirable degradability. READ MORE

  2. 2. Microplastics in the urban environment : Concentrations and composition in stormwater sediments and UV-degradation of common litter

    Author : Lisa Öborn; Helene Österlund; Maria Viklander; Mats Gustafsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microplastic; stormwater; sediment; VA-teknik; Urban Water Engineering;

    Abstract : Microplastics (MPs) are small pieces of plastic material including tyre wear particles (TWPs) smaller than 5000 µm. One of the primary pathways through which MPs including TWPs enter aquatic and marine environments is stormwater runoff from urban areas. READ MORE

  3. 3. Towards Solution Processed Electronic Circuits Using Carbon Nanotubes

    Author : Zhiying Liu; Shili Zhang; Adrian Lonescu; Uppsala universitet; []
    Keywords : ;

    Abstract : Emerging macro- and flexible electronic applications such as foldable displays, artificial skins, and smart textiles grow rapidly into the market. Solution-processed thin-film transistors (TFTs) based on single-walled carbon nanotubes (SWCNTs) as the semiconductor channel can offer high performance, low cost and versatility for macro- and flexible electronics.

  4. 4. Fatigue of Asphalt Mixes - Theory of Viscoelasticity and Continuum Damage Mechanics Applied to Uniaxial Fatigue Data from Laboratory Tests

    Author : Richard Nilsson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asphalt mixture; viscoelastic; Fatigue; deterioration models; Continuum Damage Mechanics; laboratory test; uniaxial; hydraulic engineering; Civil engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : The advance of analytic (mechanistic) design methods increases the need for fundamental material properties. Fatigue cracking due to traffic loading, in combination with permanent deformation (rutting), thermal cracking, irregularities, frost heave and reflective cracking are some of the major criteria used when designing an asphalt concrete pavement.
