Summary: A ZnO/ZnCl2 composite with stable 3D structural morphologies and long lasting superhydrophilicity was synthesized on a nanoPAA substrate. The water contact angle of the composite could be maintained at 0 degrees for 7 days and remained low even after 50 days. The superhydrophilicity mechanism was attributed to the properties of the ZnO/ZnCl2 nanofilm, wrinkled nanoflakes, nanogaps, and structural morphologies.

Summary: Enhancing hydrophilicity of polymeric materials is crucial for achieving anti-adhesiveness. This study combined atmospheric plasma pre-treatment with UV grafting process to achieve durable surface modification on PET. The most effective conditions for atmospheric plasma process were found to be 15 kW power and 4 m/min speed, resulting in a reduction in contact angle from 70 +/- 6 degrees to approximately 30 degrees. However, the contact angle increased over time due to ageing and washing of the PET surface. Therefore, the plasma-pre-treated PET samples were further modified through a UV grafting process using NaAc and KAc, which exhibited contact angles of 8 +/- 3 degrees and 28 +/- 13 degrees respectively, and showed durability in ageing and washing tests. The anti-adhesive properties of the modified PET surfaces were evaluated using Escherichia coli expressing YadA, showing a reduction in bacterial adhesion by more than 90%.

Summary: This study investigates the directional transportation of droplets using a mixed-wettability surface inspired by kingfishers' feathers. Experimental testing and numerical modelling show that the anisotropic surface can convert vertical impacting to horizontal droplets transport. The intensity and patterns of the thrown droplets are controlled by the wettability and surface offset location. The optimized surfaces can achieve a maximum horizontal transport distance of up to 6.2D0, with a first desorption time of only 7.8 ms. These findings have important implications for engineering designs in anti-icing, lubrication, and spray cooling applications.

Summary: This study demonstrates the potential of biomimetic nanocomposites in aerospace applications for anti-/deicing by utilizing surface microstructure design and flexible temperature control capabilities. The presence of surface micropillars leads to increased ice adhesion strength and decreased ice/frost formation compared to flat surfaces, while higher temperatures result in reduced contact angle and ice adhesion strength. The results suggest promising opportunities for the use of biomimetic nanocomposites in aerospace for ice prevention and removal.

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.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
