MIGRATE (www.migrate2015.eu) is a H2020 Marie Skłodowska-Curie European Training Network, intended to address some of the current challenges to innovation that faces European industry with regard to heat and mass transfer in gas-based micro-scale processes. This network of 10 participants and 6 associated partners coming from all over the European Community covers different aspects of enhanced heat transfer and thermal effects in gases: from modelling of heat transfer processes and devices, development and characterization of sensors and measurement systems for heat transfer in gas flows as well as thermally driven micro gas separators, to micro-scale devices for enhanced and efficient heat recovery in environmental, transport, telecommunications and energy generation.

The MIGRATE project of the European Community presents its International Symposium on Thermal Effects in Gas flows In Microscale (ISTEGIM 2019), taking place in Ettlingen near Karlsruhe, Germany on October 24-25, 2019. During this 2-day symposium, the members of the MIGRATE network will showcase the main achievements of the project. The program will include keynote lectures, invited lectures and contributed papers.

Micromachines (ISSN 2072-666X) is a peer-reviewed open access journal on the science and technology of small structures, devices and systems, published monthly online by MDPI.

A selection of the best long papers (8 pages and more) will be proposed by the Scientific Committee for publication in a special issue of Micromachines: https://www.mdpi.com/journal/micromachines/special_issues/ISTEGIM_19.
