  2. 1. Nanopolysaccharide coatings for functional surfaces in water-treatment materials : From mechanisms to process scalability

    Author : Andrea Aguilar Sánchez; Aji P. Mathew; Albert Mihranyan; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanopolysaccharides; coating; water treatment; nanocellulose; nanochitin; antifouling; antibacterial; separation technologies; materialkemi; Materials Chemistry;

    Abstract : In this thesis, materials from renewable resources were used to develop functionalized surfaces for water treatment. The work is thus inspired by, and contributes to, the United Nations sustainable goals of: (i) clean water and sanitation, (ii) climate action, (iii) responsible consumption and production, (iv) life below water, and (v) partnerships for the goals.

  4. 2. Polymer-coated paper and board - Role of substrate, polymer characteristics and additives

    Author : Thomas Schuman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface energy; latex; surface roughness; corona; contact angle; barrier properties; liquid sorption; surface treatment; calendering; poly vinyl alcohol ; coating;

    Abstract : The surface roughness of paper or board has a significant influence on the homogeneity of an applied polymer film, and this thesis discusses how it may be improved by a surface treatment, e.g. high-temperature calendering or precoating. READ MORE

  5. 3. High Temperature Oxidation and Corrosion of Ni-Based Superalloys for Industrial Gas Turbines

    Author : Haiping Lai; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H2O; Ni-based superalloys; Pt; electron microscopy.; surface treatment; atmosphere Na2SO4; SO2; coating; oxide scale;

    Abstract : High temperature oxidation and corrosion of Ni-based superalloys used for blades in industrial gas turbines was studied using advanced high-resolution electron microscopy methods. Both coated and non-coated alloys were tested. READ MORE

  6. 4. A Study of the Adhesion Strength of Plasma Sprayed Coatings

    Author : Fouzi Bahbou; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Splat.; Surface roughness; Mechanical anchoring; Grit blasting; Adhesion strength; Protal® process; Fractal analysis; Thermal spraying; Coating; Surface pre-treatment;

    Abstract : Surface preparation prior to thermal spraying is a key factor in ensuring a good adhesion of the coating onto the part to be coated. Surface pre-treatment conditions and methods have mainly been developed experimentally and have changed little over the years. READ MORE

  7. 5. Evaluation of Innovative Rehabilitation Technologies Utilising Polymer Composites for Aging Sewer Systems

    Author : Parastou Kharazmi; Folke Björk; Tord af Klintberg; Tor Broström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Water and wastewater sewer system maintenance is among the costliest aspects of infrastructure investment. The replacement of deteriorated lines is a difficult and expensive process that causes community disturbance and is generally not conducted fast enough to meet demand. READ MORE
