Microgravity Science and Technology opened a new topical collection that aims to advance the fundamental understanding of heat and mass transfer processes in regimes where classical, buoyancy-driven behavior is altered or suppressed.

We particularly encourage contributions that reveal new physical mechanisms, quantify deviations from Earth-based expectations, and establish links between material properties and system performance. Experimental, theoretical, and numerical studies are all welcome. The collection also highlights the growing role of PCMs in space exploration, especially in thermal management and energy systems, and highlights the mutual benefits of space-driven research for terrestrial technologies.

We invite all researchers to submit relevant contributions, original research papers as well as review articles. All submissions are peer reviewed and will be published in this collection as soon as they are accepted. Please see our submission guidelines for further technical details.

Submission deadline: 1 November 2026

Editors: Xinyu Huang (National University of Singapore), Pablo Salgado Sánchez (Universidad Politécnica de Madrid, Spain), Berin Šeta (Technical University of Denmark)
