**About the Editors**

**Lucien Baldas** (Prof. Dr.) is an expert in the numerical and experimental analysis of gas microflows, including heat transfer aspects. From 2008 to 2012, he was the assistant coordinator of the GASMEMS European Network (ITN 215504; www.gasmems.eu), which is aimed at structuring European research in the field of gas microflows, and led a work package in the MIGRATE European Project (ITN-ETN n◦ 643095), a research and training network on MIniaturized Gas flow for Applications with enhanced Thermal Effects. He has co-authored more than 100 papers in international journals and international conferences in the field of microfluidics.

**J ¨urgen J. Brandner** (Prof. Dr.) has about 25 years of expertise in microstructure devices for process engineering and miniaturized heat exchangers, materials and manufacturing for microscale systems, microsensors and sensor implementation, as well as measurement technologies for microscale devices, including in-situ and operando measurement with optical and electro-magnetic analysis systems such as high-speed videography or NMR spectroscopy. He was a member of the GASMEMS European Network (ITN 215504, www.gasmems.eu) and coordinated the MIGRATE European Project (ITN 643095, www.migrate2015.eu) from 2015 to 2019. He has authored or co-authored more than 350 papers in international journals and international conferences in the field of micro process engineering, microfluidics, micro manufacturing and heat transfer. He is a member of the Editorial Board of *Micromachines* (MDPI).

**Gian Luca Morini** (Prof. Dr.) is a Full Professor of Applied Thermal Engineering at the Department of Industrial Engineering (DIN) of the University of Bologna. He is the author of about 200 technical papers, which have appeared in the most important international journals and conferences related to microfluidics, applied thermal engineering, heat transfer and fluid flows. He is an Italian delegate of the EUROTHERM Committee, an Italian delegate of the Scientific Council of International Center of Heat and Mass Transfer (ICHMT), and a member of the Assembly of the World Conference (AWC) on Experimental Heat Transfer, Fluid Mechanics, and Thermodynamics. He is an Associate Editor of the *International Journal of Thermal Sciences* (Elsevier) and *Micromachines* (MDPI).
