Summary: In this study, carbon nanotubes were grafted by silica nanoparticles to prepare CNTs-SiO2 hybrids, which were then incorporated into an epoxy matrix to construct a superhydrophobic coating. The optimal ratio of CNTs to SiO2 was found to be 1:3, achieving the best hydrophobicity with a water contact angle of 159.3 degrees. The entwined CNTs-SiO2 hybrids not only enhanced water repellency and mechanical durability, but also showed excellent chemical stability under harsh conditions, significantly delaying water freezing time and efficiently melting ice under laser irradiation.

Summary: Superhydrophobic membranes fabricated using plasma micro-and nanotexturing followed by plasma deposition showed enhanced performance and stability in membrane distillation operations. Both hydrophobic PTFE and hydrophilic CA membranes were transformed into superhydrophobic with water static contact angles greater than 150 degrees and contact angle hysteresis lower than 10 degrees. The superhydrophobic PTFE membranes exhibited improved water flux and stable performance with salt rejection >99.99% even when exposed to low surface tension solutions. Additionally, the proposed method was effective in transforming hydrophilic CA membranes into superhydrophobic membranes with excellent performance and stability.

Summary: Micro-nanoengineered superhydrophobic surfaces can enhance heat transfer by inducing the formation of highly mobile condensate droplets. The critical role of the correlation length of topography in designing these surfaces for heat transfer applications is demonstrated. A high correlation length value leads to increased space between surface structures, resulting in improved heat transfer coefficient and delayed flooding of the surface. Therefore, correlation length is a critical criterion for optimizing surfaces for condensation heat transfer.

Summary: In this work, the complexity of microscopy images of rough surfaces is characterized using the basic ingredients of chaotic dynamics. An image is used as the initial condition of a chaotic discrete dynamical system, and its transformations during the first iterations of the map are tracked. The stretching and folding of image texture caused by the map are exploited to quantify the complexity of the image texture. The method is validated in synthetic and real images, showing interesting results.

Summary: Fluorine-containing polymers have attracted significant interest due to their hydrophobic properties. In this study, fluorinated ethylene propylene (FEP) surfaces were transformed into superhydrophobic surfaces using plasma processing. The superhydrophobicity was achieved by depositing a thin fluorocarbon coating after plasma etching with micro-nanotexturing. Video analysis revealed that increasing etching time reduced friction, creating a hierarchical morphology. The optimum performance was observed for the 10-minute etched surface in an inductively coupled plasma reactor, with an ultra-low dynamic coefficient of friction one order of magnitude lower than untreated FEP.
