    Författare :Weronica Linpe; NanoLund: Centre 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

    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.
