  1. 1. Water-Metal Surfaces : Insights from core-level spectroscopy and density functional theory

    Author : Theanne Schiros; Anders Nilsson; John Hemminger; Stockholms universitet; []
    Keywords : water; hydroxyl; metal; surfaces; x-ray spectroscopy; density functional theory; bonding; fuel cell; kemisk fysik; Chemical Physics;

    Abstract : Computational methods are combined with synchrotron-based techniques to analyze the structure and bonding of water and water plus hydroxyl at metal surfaces under UHV and at near-ambient conditions. Water-metal interaction plays a crucial role in a multitude of cosmic, atmospheric and biological phenomena as well as heterogeneous catalysis, electrochemistry and corrosion. READ MORE

  2. 2. Characterisation of Functional Pressing Die Surfaces

    Author : Johan C Berglund; Chalmers University of Technology; []
    Keywords : functional correlation; functional surface; functional filtration; pressing die; multi-scale analysis; characterisation; finish milling; texture anisotropy; polishing; surface topography;

    Abstract : The manufacture of dies and moulds is a critical aspect of many production systems since the manufacturing and try-out of new dies and moulds often is essential in determining the lead-time and quality of a new production system. In the automotive industry, many new car models are introduced each year and for each of these models, a new set of pressing dies has to be designed and manufactured. READ MORE

    Author : Erika Hult; Chalmers University of Technology; []
    Keywords : physisorption; surfaces; exchange-correlation energy; van der Waals forces; adhesion; density-functional theory;

    Abstract : .... READ MORE

  4. 4. Methods for Characterisation of Pressing Die Surfaces

    Author : Johan C Berglund; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finish milling; scale-sensitive fractal analysis; surface characterisation; polishing; functional correlation; : pressing dies; functional filtration; surface roughness; functional surface;

  5. 5. A Topographic Study of Functional Surfaces

    Author : Robert Ohlsson; Chalmers University of Technology; []
    Keywords : cylinder bore; 3D surface roughness; topography; expert system; AFM; relocation; replication; instrumentation; functional demands;

    Abstract : Surface topography through the years has taken on increased importance, because of the rise in quality demands. The surface often has to meet additional functional demands when products become more complex in accordance with customer preferences. READ MORE
