The topic focuses on electro winning of metals and alloys from a typical Martian mineral, regolith, and the production of oxygen as a byproduct, without emitting greenhouse gasses or using fossil
fuels in any phase.
The following tasks are proposed for this Master's project:
1. Investigating various available regolith-like samples.
2. Systematic preparation of regolith pellets using the pressing-sintering method.
3. Characterization of the pellets in terms of porosity, morphology (SEM), mechanical (micro-hardness) and electrical (conductivity) properties.
4. Usage of an already existing set-up for high-temperature molten salt electrolysis and the self-prepared pellets for electrowinning, focusing on the impacts of the pellet-type and electrolyte composition on the results.
5. Characterization of the samples after the run using XRD analysis in order to determinethe current efficiency

This course gives an introduction into basic features and concepts of ethics with respect to scientific research, political institutions and business. It is laid out when and how responsibility arises. Basic moral values will be introduced, and together with common moral theories, these will be applied to several typical case studies in engineering. Various Codes of Ethics will be analyzed and discussed. We will also discuss values in the design process, environmental ethics, and space ethics.
There is a reading assignment to every session, which is a text from a pool consisting of introductory teaching material, Codes of Ethics from various organizations and papers about Engineering Ethics.

Achtung: Teilnehmerzahl ist auf 18 begrenzt!

In his (short) text published in 1909, E.M. Forster sketches a dystopian scenario of a completely digitally supported interaction. After reading the text, this seminar will initiate an exchange about the experiences and insights of this summer semester and, based on this, will work out the advantages and disadvantages or helpful and hindering characteristics of digital, distanced interaction as opposed to analogue, personal interaction for various application situations.
