Humid‐Air Condensation Heat Transfer on Hierarchical Structured Superhydrophobic Graphite Composites
Advanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.Humid‐air condensation on graphite composites shows that making a surface superhydrophobic is not sufficient to enhance heat transfer. A hierarchical CuO/lauric‐acid coating yields spherical droplets but promotes Wenzel‐type pinning and adds effective thermal resistance under operation.

Statistical framework for condensation frosting incipience on smooth and nanostructured surfaces
Droplet, Volume 5, Issue 2, April 2026.A statistical framework for frost incipience that considers the effect of surface wettability and captures the stochastic nature of both nucleation dynamics for condensation and droplet growth during the subsequent freezing process. Abstract Frost and ice formation on a solid surface is governed by nanoscale liquid‒solid intermolecular interactions ...
