  1. 6. Prototype manufacturing of microwave components using plastic 3D printing

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Björn Malmquist; [2019]
    Keywords : ;

    Abstract : The ability to easily customize and produce specialized MW-components for research and industry is a real challenge and the need is identified, as standardized parts have limited use and can limit design freedom. This study aims at exploring if there are simple ways to manufacture rectangular X-band waveguides with operating frequency of 8-12GHz with novel polymer additive manufacturing and chemical metal deposition that can match Computer Numerical Control (CNC) manufactured rectangular metal waveguides in performance.

  3. 7. Morphology of electrodeposited Na on Al electrodes

    University essay from Uppsala universitet/Strukturkemi

    Author : Tim Melin; [2019]
    Keywords : Electrodeposition; Morphology; Sodium-ion batteries;

    Abstract : The demand for alternative secondary batteries to lithium-ion batteries (LIBs) grows. Sodium-ion batteries (SIBs) have been studied for many years and could replace LIBsfor some application. Metallic anodes for both LIBs and SIBs are interesting due totheir high energy densities.

  4. 8. Fabrication and Characterization of Nano-Confined Pd Catalysts for CO Oxidation

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Alfred Larsson; [2019]
    Keywords : Catalysis Palladium Nano Nanopore CO oxidation; Physics and Astronomy;

    Abstract : During this thesis nanoporous alumina has been used as a template for the synthesis of nano-confined palladium structures. The nanoporous templates have been synthesized by anodization of aluminum and characterized using atomic force microscopy (AFM), scanning electron microscopy (SEM) and small angle X-ray scattering (SAXS), resulting in good statistics of the pore diameter and interpore distance of these nanoporous structures.

  5. 9. Effect of Electrodeposition Method on Ni/SiC Composite Coating

    University essay from

    Author : Gao Jing; [2016]
    Keywords : ;

    Abstract : Abstract The work attempts to find out the effects of current parameters on particle codeposition and microhardness of composite coatings. Also, it uses pulse reverse current in increasing nanoparticle content and microhardness. READ MORE

  6. 10. Validation and development of an electroplating process to deposit a black chromium coating from a trivalent chromium electrolyte

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Josefin Sjöberg; [2016]
    Keywords : ;

    Abstract : SAAB AB coats a part of their magnetron with black chromium to enhance its ability to radiate thermal radiation. Today an electrodeposition process that has hexavalent chromium as its main component is used, but hexavalent chromium is carcinogenic and will be prohibited. READ MORE
