Journal ArticleDOI
Time dependency of the hydrophilicity and hydrophobicity of metallic alloys subjected to femtosecond laser irradiations
TL;DR: In this article, the effect of time on the wettability of metallic alloys was investigated, and it was shown that the change from hydrophilicity to hydrophobicity occurred over time and is due to surface chemistry modifications.
Journal ArticleDOI
The effects of femtosecond laser-textured Ti-6Al-4V on wettability and cell response
Ophélie Raimbault,Stéphane Benayoun,Karine Anselme,Cyril Mauclair,Tatiana Bourgade,Anne-Marie Kietzig,Pierre-Luc Girard-Lauriault,Stéphane Valette,Christophe Donnet +8 more
TL;DR: Results showed that cells are more sensitive to the nanoscale structures (LIPSS), unless the microstructures's size is close to the cell size and deeper than 5μm, there, the cells aresensitive to the microscale structures and go on spreading following these structures.
Journal ArticleDOI
Wettability versus roughness: Multi-scales approach
TL;DR: In this paper, a model combining the Wenzel and Cassie-Baxter equations with the 3D roughness parameters defined by ISO 25178 was proposed to investigate the influence of multi-scale roughness on contact angle measurements.
Journal ArticleDOI
Wear Protection without Surface Modification Using a Synergistic Mixture of Molecular Brushes and Linear Polymers
Jimmy Faivre,Buddha Ratna Shrestha,Joanna Burdynska,Guojun Xie,Florina Moldovan,Thierry Delair,Stéphane Benayoun,Laurent David,Krzysztof Matyjaszewski,Xavier Banquy +9 more
TL;DR: It is demonstrated that this synergy between the BB and HA polymers emerges from a strong cohesion between the two components forming the boundary film due to entanglements between both polymers, and can be applied to other types of linear polymers and surfaces and is independent of the chemical and mechanical properties of the surfaces.
Journal ArticleDOI
Functionalization of titanium with chitosan via silanation: evaluation of biological and mechanical performances.
TL;DR: Results proved that covalent coating of chitosan has significant potential in biomedical device implantation and provides a biocompatible material with improved bioactive properties.
