  3. 12. From Current Collectors to Electrodes : Aluminium Rod Structures for Three-dimensional Li-ion Micro-battery Applications

    Författare :Gabriel Oltean; Kristina Edström; Leif Nyholm; Erik Kelder; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D micro-batteries; aluminium; titanium oxide; current collectros; negative electrodes; electrodepostion; electrophoretic depostion; sol-gel synthesis;

    Sammanfattning : The potential use of 3D aluminium nanorod structures as current collectors and negative electrodes for 3D Li-ion micro-batteries was studied based on the use of relatively simple and cost-effective electrochemical and sol-gel deposition techniques.Aluminium rod structures were synthesised by galvanostatic electrodeposition using commercial porous membranes as templates.

  4. 13. Scanning Tunnelling Microscopy and Spectroscopy of Adsorbates on Aluminium and Silicon

    Författare :Mikael Johansson; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alkali metals; Scanning tunnelling spectroscopies; Scanning tunnelling microscopy; Photoelectron Spectroscopy; Single crystal surface; Silicon; Surface structure; Aluminium; Silicides; Fullerenes.; Physics; Fysik; Fysicumarkivet A:1997:Johansson;

    Sammanfattning : The main topic of this thesis is the investigation of atomic andmolecular adsorbates on single crystal surfaces of silicon and aluminiumusing the techniques of scanning tunnelling microscopy (STM) andspectroscopy (STS). The emphasis has been to use atomic-resolutionspectroscopy and imaging to determine the relationship between thesurfaces' geometric and electronic structures. LÄS MER

  7. 15. Adverse Reactions after Vaccination and Allergen-Specific Immunotherapy: Contact Allergy to Aluminium and Itching Nodules

    Författare :Eva Netterlid; Yrkes- och miljödermatologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patch test; Itching nodules; Contact allergy; ASIT; Aluminium; Allergen-specific immunotherapy; Adverse event; Parental reports; vaccination;

    Sammanfattning : The aim of the work presented in this thesis was to investigate two different types of adverse reactions, persistent itching nodules and contact allergy to aluminium, after immunization with aluminium-containing vaccines and aluminium-containing allergen extracts used for allergen-specific immunotherapy (ASIT). The first paper describes active parental reporting of adverse events (AEFIs) after a booster dose of diphtheria-tetanus vaccine (DT). LÄS MER
