  1. 1. Measuring copper abundances in the Galactic Bulge

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Nikolei Höglinger; [2024]
    Keywords : Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

    Abstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

  2. 2. Innovative approaches to recycling of small and electric motors from end-of-life vehicles, electric bicycles and industrial machinery

    University essay from KTH/Industriell ekologi

    Author : Rainer Link; [2016]
    Keywords : recycling potential; end-of-life vehicles; electric bicycles; electric motor; rare earth element recycling;

    Abstract : Recycling and recovery of materials and energy from waste is a key factor to mitigate virgin material demands and reduce resource consumption by utilising waste as a resource for new products. However, some critical materials, such as neodymium, are barely recycled because of missing information on amount and disposition of these critical materials within the waste streams. READ MORE

  3. 3. Potential Ecodesign Directive Contributions to Resource-Efficient Innovations. A Case Study on the Electric Motor Product Group Expansion and Rare Earth Element Use in Permanent Magnet Motors

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Erika Machacek; [2012]
    Keywords : Ecodesign Directive; Innovation; Resource Efficiency; Rare Earth Elements; Permanent Magnet Motors.; Technology and Engineering; Earth and Environmental Sciences; Law and Political Science;

    Abstract : This study looks at potential contributions of the Ecodesign Directive 2009/125/EC to eco-innovations addressing resource efficiency improvements of energy-related products. This aim is secondary to the prime objective of the Directive, the increase in energy efficiency of energy-related products. READ MORE
