2. 1. Using Light to Probe Surface Electrochemical Processes

   Author : Weronica Linpe; NanoLund: Centre for Nanoscience; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. Lithium intercalation in tin oxide films : Physics and electrochemistry

   Author : Jan Isidorsson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Abstract : Tin oxide films were made by reactive rf magnetron sputtering under conditions that led to both electronic and ionic conductivity. It was found that a high sputter pressure promoted porosity and a high charge capacity. READ MORE

5. 3. Superparamagnetic iron oxide nanoparticles, a novel tracer in breast cancer surgery

   Author : Abdi-Fatah Hersi; Staffan Eriksson; Fredrik Wärnberg; Andreas Karakatsanis; Thorsten Kühn; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast Cancer; superparamagnetic iron oxide nanoparticles; SPIO; magnetic seed; magnetic surgery; sentinel node; sentinel node biopsy; nonpalpable; ductal carcinoma in situ; DCIS; Surgery; Kirurgi;

   Abstract : The most common surgical choice of treatment in breast cancer is breast-conserving surgery (BCS) together with sentinel lymph node biopsy (SNB). Around 10% of breast cancer diagnosis are ductal carcinoma in situ (DCIS). Superparamagnetic iron oxide nanoparticles (SPIO) are a novel tracer for sentinel lymph node (SN) detection. READ MORE

6. 4. In situ observations of tin deposition into nanoporous anodic aluminium oxide

   Author : Weronica Linpe; NanoLund: Centre for Nanoscience; []
   Keywords : 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;

   Abstract : 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.

7. 5. Cation intercalation and surface fractality in metal oxide based films

   Author : Maria Strømme Mattsson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Abstract : New methods have been developed for determining the fractal dimension df of asurface from cyclic voltammograms with the sample of interest serving as the workingelectrode in an electrochemical cell. The methods have been verified by applying them tovoltammograms recorded on gold samples with a well-defined fractal dimension. READ MORE
