Key Points
Enhanced heat-transfer was observed due to increased surface roughness, leading to improved phase change dynamics.
Key evidence showed that the surfaces with wettability contrast achieved a 25% increase in heat-transfer efficiency during tests.
Analysis using thermal conductivity measurements confirmed that roughness plays a crucial role in evaporation rates across diverse surfaces.
These findings support the development of advanced cooling technologies, potentially impacting energy-efficient systems.
