  2. 1. Concrete Bridges : Improved Load Capacity

    Author : Jonny Nilimaa; Terje Kanstad; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : There are many beautiful old structures around the world, some of which were designed for completely different purposes than their current applications. For example, Swedish railway bridges were only designed to carry axle loads up to 200 kN in the beginning of the 20th century, while modern loads can be twice as high. READ MORE

  4. 2. Structural Modifications of Lignosulphonates

    Author : Dimitri Areskogh; Gunnar Henriksson; Arthur J. Ragauskas; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Abstract : Lignosulphonates are by‐products from the sulphite pulping process for the manufacture ofspecialty dissolving pulps and paper. During the liberation of the cellulose, the lignin isfractionated and solubilised through covalent addition of sulphonic acid groups at variouspositions in the structure. READ MORE

  5. 3. Polymer and Protein Physics : Simulations of Interactions and Dynamics

    Author : Anna Sinelnikova; Johan Nilsson; Carl Caleman; Erik Lindahl; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymers; proteins; Monte Carlo; molecular dynamics; phase diagram; renormalisation group; SPI; polymer effective model; coarse-graining; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Proteins can, without any exaggeration, be called the "building blocks of life". Their physical properties depend not only on the chemical structure but also on their geometric shape. In this thesis, I investigate protein geometry using several different methods.We start with a coarse-graining model to study the general behavior of polymers. READ MORE

  6. 4. Strengthening reinforced concrete structures with FRP composites

    Author : Jincheng Yang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GFRP; finite element analysis.; corrosion; interfacial stress; externally bonded reinforcement; self-anchorage; CFRP; debonding; concrete structures; Fibre reinforced polymer; prestressing level;

    Abstract : Civil infrastructures made of reinforced concrete (RC) play an important role in the economic activities and services of society. However, signs of deterioration and functional deficiency are commonly found in existing RC structures. Thus, there is a great demand for upgrading the capacity and performance of existing concrete structures. READ MORE

  7. 5. Advanced Functional Thin Films and Networks towards Biological Applications

    Author : Surinthra Mongkhontreerat; Michael Malkoch; Anders Hult; David Haddleton; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Abstract : Functional polymeric scaffolds have been employed in biological applications as several utilities, from nano-sized drug delivery systems to concrete implants. The progression in biological fields essentially relies on finding an appropriate material to fulfil the critical requirements for various types of applications with great potential for tuning functionality and mechanical properties.
