Summary: Prevention of bacterial adhesion is important in reducing biofilm formation and associated infections. In this study, a PET film was modified with silica nanoparticles and fluorinated carbon chains to create a superhydrophobic surface. However, contrary to expectations, bacterial adhesion, specifically of E. coli YadA, increased on the modified PET surfaces. This highlights the significance of material micro topography in bacterial adhesion.

Summary: This study presents a new method to collect 3D confocal images of irregular polysiloxane micro- and nanorods for discussing their wetting response and quantifying their dimensions. Through different staining scenarios, the researchers were able to resolve the micro- and nanorods and validate the results against electron microscopy images. The findings from the 3D confocal images shed light on the long-time existence of multiple wetting states and the shifting and pinning of three-phase contact lines under the same droplet on surfaces.

Summary: A superhydrophobic surface with micro/nanoscale structures was designed by employing facile and low-cost demolding and initiated chemical vapor deposition (iCVD) processes. The achieved micro/nanostructured superhydrophobic surface exhibited a maximum static contact angle of about 170 degrees, a roll-off angle and contact angle hysteresis below 1 degree, ultralow solid/liquid adhesion for water droplets, and maintained excellent superhydrophobicity even after exposure to strongly corrosive substances for 60 hours. This reasonably-designed method provides valuable guidelines for the manufacture of transferable superhydrophobic surfaces and enables potential applications in optoelectronic devices and self-cleaning materials.

Summary: The susceptibility of surface-modified wood, surface-modified acetylated wood and acetylated wood to mold and blue stain fungi was investigated. The surface modifications based on fluorinated and non-fluorinated silicone nanofilaments increased the hydrophobicity, resulting in enhanced mold resistance for the surface-modified superhydrophobic wood. Acetylated wood samples exhibited good mold resistance due to reduced available water, while surface modifications on acetylated wood slightly negatively affected mold resistance.

Summary: We propose an environmentally friendly and cost-effective method to enhance nanoscale structures on metallic surfaces through thermo-mechanical and microwave-assisted hydrothermal processing. The processing of the aluminium alloy resulted in significant grain refinement, and after hydrothermal treatment, nanostructured morphology was observed. The processed samples exhibited high water-repellent properties and mechanical resilience due to the unique interfacial energy and negative capillary pressure of the nanostructures. These findings provide practical approaches for achieving anti-wetting surfaces in different industrial settings.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
