Engineering the surface of a material can profoundly influence how heat is transferred or retained in a system. By tailoring surface characteristics such as roughness and wettability, engineers can enhance heat transfer coefficients or mitigate thermal losses according to specific needs. For instance, textured or rough surfaces and micro/nano-structuring are known to disturb boundary layers, thereby increasing convective mixing and nucleation for improved heat dissipation. Additionally, changes in surface wettability can alter condensation modes, leading to increase heat transfer efficiency. Conversely, carefully designed coatings and surface treatments, such as thermal barrier coatings, can insulate components, sustaining large temperature differences and protecting underlying materials. This dual capability highlights the importance of surface properties in modern thermal management strategies.

This Research Topic explores surface-driven thermal transport phenomena, focusing on how surface characteristics influence heat conduction, convection, phase-change and radiative heat transfer. The aim is to showcase insights into multi-scale heat transport, from fundamental mechanisms at micro/nanostructured interfaces to overall system performance. This Research Topic will shed light on how engineered surface properties can control thermal transport across scales, inspiring innovative strategies for both augmenting heat dissipation and achieving superior insulation as needed in future technologies. By bringing together this knowledge, this collection will provide a robust understanding that facilitates the predictive design of surfaces aimed at specific thermal outcomes, bridging the gap between theoretical thermal sciences and practical surface engineering.

Studies ranging from fundamental physics and modelling of interfacial heat transfer to applied research on engineered surfaces in real systems are welcome. Both experimental investigations and simulations are encouraged, particularly studies that connect surface microstructure with macro-scale thermal performance. Interdisciplinary approaches are also encouraged.
