  2. 1. Localised corrosion and atmospheric corrosion of stainless steels

    Author : Sukanya Hägg Mameng; Rachel Pettersson; Christopher Leygraf; Thomas Ladwein; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; localised corrosion; atmospheric corrosion; alloy composition; surface finish; surface roughness; surface treatment; surface orientation; contamination; chloride; sulphate; temperature; chlorination; exposure conditions.; Kemi; Chemistry;

    Abstract : This research is focused on defining limiting conditions for corrosion of stainless steels. The aim of the first part (Papers I-IV) was to understand the role of alloying level and environmental parameters on localised corrosion in aqueous conditions. READ MORE

  4. 2. Surface Force and Friction : effects of adsorbed layers and surface topography

    Author : Xiaoyan Liu; Per Claesson; Bjorn Torger Stokke; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; nanotribology; surface forces; diblock copolymer; lipid; QCM-D; AFM; optical reflectometry; neutron reflectivity; X-ray reflectivity; micro-patterned surface; Kemi; Chemistry;

    Abstract : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. READ MORE

  5. 3. Spatial variations of the urban climate and its influence on thermal comfort and behaviour

    Author : Fredrik Lindberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sky view factor; air temperature; surface temperature; GIS; raster modelling; mean radiant temperature; globe temperature; the SOLWIEG-model; human behaviour; outdoor activity;

    Abstract : The increased number of people living in urban areas emphasises the need for an improved understanding of how the urban climate affects human activity and behaviour. The spatial and temporal variation of climate within cities is an important factor in people’s health and well-being. READ MORE

  6. 4. Properties of modified starches and their use in the surface treatment of paper

    Author : Anna Jonhed; Lars Järnström; Ann-Charlotte Eliasson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface treatment of paper; hydrophobically modified starches; temperature-responsive starch; inclusion complexes; barrier properties; Surface engineering; Ytbehandlingsteknik; Chemical Engineering; Kemiteknik;

    Abstract : The papermaking industry uses a large amount of starch each year, both as a wet-end additive and as a rheological modifier in surface sizing and coating colors. It is important to be able to reduce the amount of chemicals used in the papermaking and surface treatment process, to reduce costs and to make the process even more efficient. READ MORE

  7. 5. High Temperature Corrosion in Fluidised Bed Environment

    Author : Anna Nafari; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFB; coatings; Ni and iron based alloys; HCl; SO2; loop seal; High temperature corrosion; erosion corrosion test rig; surface characterization and temperature gradient;

    Abstract : Successful material selection for power plants is the result of understanding the environment in each boiler. The boiler environment is affected by fuel chemistry, co-firing, process control and deposits as well as boiler type, design, size and load. READ MORE
