  2. 1. 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

  4. 2. Ni-based coatings for high temperature corrosion protection

    Author : Esmaeil Sadeghimeresht; Shrikant V. Joshi; Nicolaie Markocsan; Petri Vuoristo; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Spray Coating; HVAF; High Temperature Corrosion Protection; Composition; Microstructure; Dispersed Oxide; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Biomass/waste-fired boilers severely suffer from high temperature corrosion of critical load-bearing components, e.g. water-wall and superheater tubes, due to presence of Cl-containing corrosive species. READ MORE

  5. 3. Modeling of frost heave and surface temperatures in roads

    Author : Åke Hermansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Temperature and moisture are very essential parameters when describing the condition of a pavement. In most cases, a high moisture content involves a decreased bearing capacity and, consequently, a shorter durability of the pavement. A frozen pavement has a greater bearing capacity than the corresponding construction in spring or late autumn. READ MORE

  6. 4. Development of materials, surfaces and manufacturing methods for microfluidic applications

    Author : Carl Fredrik Carlborg; Wouter van der Wijngaart; Shoji Takeuchi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microsystem technology; MEMS; microfluidics; polymers; off-stoichiometry thiol-ene; point-of-care; lab-on-chip; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : This thesis presents technological advancements in microfluidics. The overall goals of the work are to develop new miniaturized tests for point-of-care diagnostics and robust super-lubricating surfaces for friction reduction. To achieve these goals, novel materials, surfaces and manufacturing methods in microfluidics have been developed. READ MORE

  7. 5. Homogenization with applications in lubrication theory

    Author : Afonso Fernando Tsandzana; Anders Holmbom; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : In this licentiate thesis we study some mathematical problems in hydrodynamic lubrication theory. It is composed of two papers (A and B) and a complementary appendix. Lubrication theory is devoted to fluid flow in thin domains. The main purpose of lubrication is to reduce friction and wear between two solid surfaces in relative motion. READ MORE
