  1. 1. Characterization of surface defects caused by ultrasonic cleaning of aluminium

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Emanuel Eriksson; [2022]
    Nyckelord :Ultrasonic cleaning; surface cleaning; metal; aluminium; 7050; 2050; defects; surface defects; Energy Dispersive Spectroscopy; Scanning Electron Microscopy; Vertical Scanning Interferometry;

    Sammanfattning : This master thesis studies the behaviour of two aluminium alloys in ultrasonic cleaning at two different intensities, as well as the effect of a cleaning solution, Formula 815 GD-NF on the same surface have been studied with respect to surface roughness and material composition. Methods like Light Optical Microscopy (LOM), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and 3D topography using white light interferometry (VSI) was used to study the surface and material composition.

  3. 3. THE EU AS A SPACE POWER A path towards integration or interdependence?

    Magister-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Mahesh Karthik; [2021-07-01]
    Nyckelord :The European Union; European Space Agency; European Space Policy; Cooperation; Security; Sustainability; Economy; Framework Programmes;

    Sammanfattning : This thesis aims to explore the synergies (or the lack thereof) in the actions and programmes of the European Union in conjunction with the European Space Agency in the areas of the space-based economy, space-based sustainability, and space-based security, based on the joint statement signed in 2016 by the two organizations. The joint statement said that the organizations would work in close cooperation with each other for unified and concerted progress within the space sector. LÄS MER

  4. 4. The Climate Case versus The Business Case The Drivers and Motivations for Early Market Adoption of Renewable Energy Innovations

    Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

    Författare :Sofie Lindström; Michaela Stensjö; [2021-06-30]
    Nyckelord :Adoption; Early Market; Eco-Innovations; Renewable Energy; Start-ups; the Paris Agreement.;

    Sammanfattning : The world has committed to a low-carbon global economy where renewable energy is believed to be one key enabler in the green energy transition. However, the adoption of renewable energy innovations is currently too slow to reach the Paris Agreement by 2050. LÄS MER

  5. 5. A EUROPEAN (NO) COAL AND (GREEN) STEEL COMMUNITY? - A Technological Innovation System case approach in the fossil-free steel sector

    Master-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Hannes Wigerfelt; [2021-06-28]
    Nyckelord :Green steel; HYBRIT; Hydrogen; Technological Innovation System;

    Sammanfattning : The EU has committed to reaching carbon neutrality by 2050 and thereby heavily reducing the emissions of greenhouse gases. Policymakers and scholars have pointed out the development of fossil-free technological energy innovations as crucial in reaching these objectives. LÄS MER
