    Sammanfattning : In this thesis, the studies of native and anodic oxides on both aluminum model single crystal surfaces as well as on aluminum alloys found in applications are presented. The focus has been on the characterization in situ as the oxide is growing by an electrochemical process called anodization. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; XRD; XRF; GTSAXS; XANES; Synkrotronljus; Elektrokemisk deposition; Anodisering; Tinn; Aluminiumoxid; Porös aluminiumoxid; In situ; XRD; XRF; GTSAXS; XANES; Synchrotron radiation; Electochemical deposition; Anodisation; Sn; Native aluminium oxide; Porous aluminium oxide; Nanoporous anodic aluminium oxide; In situ;

    Sammanfattning : AbstractIn this thesis, the electrochemical deposition process of Sn into ordered nanoporous anodic aluminium oxide (NP-AAO) have been studied. The deposition process was studied in situ using the X-ray techniques: X-ray diffraction (XRD), Grazing incidence Transmission Small-Angle X-ray Scattering (GTSAXS), X-ray Fluorescence (XRF) and X-ray Absorption Near Edge Structure (XANES) and ex situ using Focused Ion Beam-Scanning Electron Microscopy and Transmission Electron Microscopy measurements.

  3. 3. Using Light to Probe Surface Electrochemical Processes

    Författare :Weronica Linpe; NanoLund: Center for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrochemistry; X-ray methods; In situ; synchrotron radiation; Ex situ; Single crystal; polycrystalline; aluminium oxide; Au; Pd; Pt; Sn; Super duplex stainless steel.; Fysicumarkivet A:2021:Linpé;

    Sammanfattning : This thesis shows how various light-based in situ techniques can be used to follow different surface electrochemical processes such as electrochemical deposition into Nanoporous Anodic Aluminium Oxide (NP-AAO) templates and the surface structure of electrodes. Techniques based on both x-rays and visible light were used to follow surface structures and compositions, in situ. LÄS MER
