Research Topics

In the MIGRATE innovative training network, the aforementioned challenges with regard to heat and mass transfer in gas-based micro-scale processes are addressed. Different aspects of enhanced heat transfer and thermal effects in gases are defined to build the research topics of the 15 Early-Stage Researchers (ESRs).

In the following, the research topics of the 15 ESR projects are listed. On the global project level these are cross-linked with the overall topics of the work package tasks and research groups of MIGRATE. The intersectoral and multidisciplinary collaboration network is offers training to combine these sub-topics.
