Background
Thermoelectric (TE) materials convert temperature differences directly into electrical energy via the Seebeck effect. This current thesis aims to provide an overview of TE materials, the material flow and the possible recycling routes.
Job Definition
Conducting a literature review that covers the following topics:
– Market demand and supply of thermoelectric materials
– Supply chain and reverse logistics (recycling)
– Compiling state of the art methods for processing TE wastes
– Identifying challenges and needs for improvement base on compilation

Background
Fluidised bed reactor is a type of reactor where solid particles are suspended in flowing stream of gas or liquid. A new design of a top-blown fluidised bed reactor had been tested and needs to be optimised based on CFD simulations on different designs of the gas lance.
Job Definition
– Modelling of the current reactor and simulation of fluid flow and temperature profile
– Optimisation of the fluid flow through alternative dimensions of gas lance
– Experimental validation of simulated results using
Requirement: Proficiency in Ansys, COMSOL, or comparable CFD software

Background
In this thesis, the possibility of thermochemical treatment of various mineral fine fractions is investigated. Due to their heterogeneity, potential contamination and non-economic use, they are not often integrated into circular economy systems. With thermal conditioning, there are promising approaches for the utilization of these materials in building material applications. The aim is to identify suitable mixing ratios for different mineral fine fractions and to determine the required process parameters. For achieving this, thermochemical data sets are created using FactSage and then analyzed using machine learning methods. This approach enables a much more efficient search for possible process windows and opens up the opportunity to identify previously undiscovered options.
Job Definition
Data set generation: Creation of thermochemical data sets using FactSage software in previously defined process windows.
Modeling: Application of machine learning methods to analyze the generated data sets and identification of optimal process parameters and mixing ratios through modeling results.ork
