Abstract Scope As a consequence of surface modification with sulfuric acid, titanium surfaces exhibited growth of novel rosette-like two-dimensional formations. It is most likely that this nano formations evolve as a consequence of chemical reactions of sulfuric acid and oxygen on insufficiently rinsed Ti specimens, after water has evaporated or removed by convection. This new surface features can have important implications in corrosion science and applied fluid-surface interactions, just to name a few. Possible applications of this new crystal morphology can be inspired by the uses developed for similar titanium-based nanocrystals. Several authors have developed techniques for the hydrothermal synthesis of tiny (2-5 micron) flower-like titanium phosphate crystals, designed to improve its use in photocatalysis applications. In the biomedical realm, titanium oxide films with a flower-like nanostructure have been used to improve the corrosion resistance of magnesium alloy vascular stents.
