  1. 1. Surface Characterisation Using ToF-SIMS, AES and XPS of Silane Films and Organic Coatings Deposited on Metal Substrates

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ulf Bexell; Uppsala universitet.; Högskolan Dalarna.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; materialvetenskap; Materials Science; Materials science; Silanes; Organic films; ToF-SIMS; AES; XPS; Materialvetenskap;

    Abstract : This work focuses on the surface and interfacial characterisation of silane films of a non-organofunctional silane, 1,2-bis(triethoxysilyl)ethane (BTSE), and an organofunctional silane, γ-mercaptopropyltrimethoxysilane (γ-MPS), deposited on Al, Zn and Al-43.4Zn-1.6Si (AlZn) alloy coated steel.

  2. 2. Rare-gas Clusters Studied by Electron Spectroscopy Structure of Heterogeneous Clusters and Effects of Electron Scattering on Auger Decay

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Marcus Lundwall; Uppsala universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Nano-particles; Clusters; Heterogeneous clusters; Core-shell clusters; XPS; UPS; AES; Electron scattering; Radial structure; Surface structure; Surface sensitivity; Synchrotron radiation; Ne; Ar; Kr; Xe; Fysik;

    Abstract : In this Thesis experimental studies of nano-clusters using synchrotron radiation based photoelectron (UPS and XPS) and Auger Electron Spectroscopy (AES) are presented. The investigations may be divided into two parts where the first reports on the structure of heterogeneous two component clusters, and the second concerns electronic decay processes. READ MORE

  3. 3. ROLE OF SURFACE OXIDES IN SINTERING OF CHROMIUM-ALLOYED STEEL POWDER

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Henrik Karlsson; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water atomisation; surface analysis; sintering; chromium-alloyed steel.; Powder metallurgy; surface reactions; surface; surface oxide; SEM; XRD; AES; XPS;

    Abstract : During water-atomisation and handling of steel powder the surface inevitably oxidises. The surface bound oxide is an important factor in the processing of powder metallurgical (PM) steels, especially in case the powder contains elements forming stable oxides, such as Cr, Mn, and Si.

  4. 4. Traffic Safety Potential and Effectiveness of Lane Keeping Support

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Simon Sternlund; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CLRS; ELK; Traffic Safety; Lateral positioning; LDW; AES; Lane keeping; Effectiveness;

    Abstract : In the road transport system, crashes due to lane departure account for a large proportion of the most severe crashes that passenger car occupants are exposed to. While Electronic Stability Control (ESC) effectively prevents lane departure due to loss of control, lane departure due to unintentional drifting has not been addressed to the same extent. READ MORE

  5. 5. Free Neutral Clusters and Liquids Studied by Electron Spectroscopy and Lineshape Modeling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henrik Bergersen; Uppsala universitet.; [2008]
    Keywords : Physics; Clusters; Nano-particles; XPS; UPS; AES; Radial structure; Molecular dynamics; Density functional theory; Liquids; Liquid microjet; Solvation; Fysik;

    Abstract : The electronic and geometrical structure of free neutral clusters and liquids have been studied using synchrotron-radiation based photoelectron and Auger electron spectroscopy in combination with lineshape modeling. A novel experimental setup has been developed for studies of liquids, based on the liquid microjet technique. READ MORE
