  1. 1. Alkali Metal Adsorption on Metals Studied by Hiqh Resolution Core Level Spectroscopy and Low Energy Electron Diffraction

    Författare :Edvin Lundgren; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Low Energy Electron Diffraction; Physics; Core Level Spectroscopy; Surface Structures Photoelectron Emission; Single Crystal Surfaces; Alkali Adsorption; Aluminium; Metals; Alkali Metals; Fysik; LEED.; Fysicumarkivet A:1996:Lundgren;

    Sammanfattning : Alkali metal adsorption on metals is studied by High Resolution Core Level Spectroscopy (HRCLS) and Low Energy Electron Diffraction (LEED). The studies can be divided into two parts: adsorption of alkali multilayers and alkali adsorption in the submonolayer regime. LÄS MER

  3. 2. Interfaces in Li-ion batteries seen through photoelectron spectroscopy

    Författare :Ida Källquist; Maria Hahlin; Håkan Rensmo; Laurent Duda; Kristina Edström; Edvin Lundgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : To accommodate the need for greener energy solutions renewable energy sources aswell as reliable energy storage is a prerequisite. For the latter, high energy densitybatteries with long-term cycling stability are necessary. The cycling properties of abattery is to a large extent dependent on the functionality of the battery interfaces. LÄS MER

  4. 3. Passivity & Breakdown of Super Duplex Stainless Steel : Studied with Electrochemical & Synchrotron Techniques

    Författare :Marie Långberg; Jinshan Pan; David Lindell; Ulf Kivisäkk; Edvin Lundgren; Sannakaisa Virtanen; KTH; []
    Nyckelord :Passive film; duplex stainless steel; synchrotron X-ray reflectivity; X-ray diffraction; X-ray fluorescence; hard X-ray Photoelectron emission microscopy; X-ray Photoelectron spectroscopy; Electrochemical impedance; Kemi; Chemistry;

    Sammanfattning : Super duplex stainless steel consists of two phases: austenite and ferrite, and is a highly corrosion resistant material, with a wide range of applications. The corrosion resistance of stainless steels is determined by the performance of a spontaneously formed thin Cr oxide rich film with a thickness of 1-3 nm. LÄS MER
