Journal ArticleDOI
Metal–Support Interactions between Nanosized Pt and Metal Oxides (WO3 and TiO2) Studied Using X-ray Photoelectron Spectroscopy
TL;DR: In this paper, the binding energy of the Pt 4f signal for platinum nanoparticles on an oxide support was significantly lower in comparison to samples where Pt was solely supported onto carbon.
Journal ArticleDOI
Characterization of a calcium phosphate–TiO2 nanotube composite layer for biomedical applications

TL;DR: In this article, the effect of annealing titania nanotubes at 600°C on their morphology and structure was examined using SEM and TEM techniques, which indicated that the nanotubular titania layer became stable after anneal at 600-°C, while its internal structure changed from amorphous to crystalline anatase, and eventually, a mixture of anatase and rutile.
Journal ArticleDOI
Improvement of the bio-functional properties of TiO2 nanotubes
Agata Roguska,Marcin Pisarek,Anna Belcarz,Lionel Marcon,Marcin Holdynski,Mariusz Andrzejczuk,Maria Janik-Czachor +6 more
TL;DR: In this paper, three factors were found to promote the proliferation of osteoblast (U2OS) cells: a larger nanotube diameter, a higher annealing temperature, and the presence of a thin Ca-P layer.
Journal ArticleDOI
Surface-enhanced Raman scattering (SERS) activity of Ag, Au and Cu nanoclusters on TiO2-nanotubes/Ti substrate
Agata Roguska,Agata Roguska,Andrzej Kudelski,Marcin Pisarek,Marcin Pisarek,Magdalena Opara,Maria Janik-Czachor +6 more
TL;DR: In this paper, the surface-enhanced Raman scattering (SERS) was applied on a TiO2 nanotube/Ti substrate for sputter deposition of Ag, Au or Cu.
Journal ArticleDOI
Surface characterization of Ca-P/Ag/TiO2 nanotube composite layers on Ti intended for biomedical applications.

TL;DR: It has been found that the silver nanoparticles are distributed homogeneously in the coating, which is promising for maintaining a steady antibacterial effect and may offer unique surface features for biomedical implants, ensuring both biocompatibility and antibacterial properties.
