Summary: Micro/nano scale surface modifications of titanium based orthopedic and cardiovascular implants have been shown to improve biocompatibility. However, bacterial infection remains a major concern for implant failure. Recent studies have found that superhydrophobic surfaces can prevent protein and bacterial cell adhesion. This study used a thermochemical treatment to modify the properties of the titanium surface and achieved superhydrophilic and superhydrophobic surfaces by modifying with polyethylene glycol and silane, respectively. The modified surfaces significantly reduced bacterial cell adhesion and prevented biofilm formation.

Summary: Micro/nano-hierarchical structures composed of nanohairs on top of micropillars were produced using high-resolution two-photon lithography additive manufacturing technique. Varying the tapering angle of the micropillar and the length of the nanohairs allowed control over the effective stiffness of the structures. In-situ monitoring of the structural deformation and frictional response revealed that changes in structure stiffness through 3D printing could affect the onset of sliding motion, friction force, and coupling between nanohair and micropillar deformation, providing new directions for friction and deformation control.

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.
