  1. 1. Effects of natural aging and low strain-rate on mechanical properties of aluminium alloy sheets used in automotive industry

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Amirhossein Gholami; Ali Abedisamarin; [2024]
    Nyckelord :Ageing. AA6014. AA6016;

    Sammanfattning : These days, lightweight materials such as aluminum alloy sheets, especiallythose in the AA6xxx series, are in high demand for use inthe automotive industry. During natural aging, the properties of aluminummay undergo significant changes due to the diffusion of atomswithin the crystal structure, impacting the strength and formabilityof aluminum sheets.

  3. 2. Structural analysis of HZO thin film and electrode using X-ray diffraction

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Elliot Winsnes; [2024]
    Nyckelord :HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Sammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER

  4. 3. Synthesis and Characterization of Materials for Carbon Based Hybrid Asymmetric Supercapacitor Electrodes

    Master-uppsats, KTH/Tillämpad fysikalisk kemi

    Författare :Avital Cherednik; [2023]
    Nyckelord :Supercapacitor; hybrid supercapacitor; metal oxide nanoparticles; carbon electrodes; ionic liquid; Superkondensator; hybrid superkondensator; metaloxid nanopartiklar; kolelektroder; jonvätska;

    Sammanfattning : Superkondensatorer är energilagringsenheter som har uppmärksammats mer under det senaste decenniet. Några av de fördelar som dessa enheter har varit är lagring av hög effekttäthet, förlängda livscykler och snabba laddnings- och urladdningstider. LÄS MER

  5. 4. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Aidas Urbonavicius; [2023]
    Nyckelord :ETEM; Nucleation; GaSb; Nanowires; Materials chemistry; Technology and Engineering; Chemistry;

    Sammanfattning : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. LÄS MER

  7. 5. Investigation of enzymatic mediated CO2 capture : A computational study of enzymatic systems

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Amelie Grunditz; [2023]
    Nyckelord :;

    Sammanfattning : Enzymes converting CO2 can be helpful with battling today’s environmental problems with global warming due to greenhouse gases. It can also contribute to make industrial processes cheaper and cleaner. During this project, enzymes have been studied to understand the process better. LÄS MER
