The hybrid surface combines hydrophobic nanowires and hydrophilic channels to prevent flooding of condensation
Schematic diagram of a 3D hybrid surface showing anti-loading properties by combining SEM images with film width and drop condensation. Credit: National Taiwan University Condensation is important for applications such as power generation, water harvesting, and cooling systems. However, when the surface temperature is much lower than the ambient steam, traditional surfaces suffer from poor performance under high sub-cooling. This…

New ways to engineer composites: polymer design combines strength and reversibility
Silica nanoparticles blended into polystyrene chains (purple) distribution and hexagonal lattice. Depending on how the chain is organized on the surface of the particles, it is intertwined when compressed (purple) or untangled (blue). Credit: Tiffany Chen; XU Composite adhesives, such as epoxy resins, are great tools for bonding and filling materials such as wood, metal, concrete. But there is one…
