Functional Nb2O5 film and Nb2O5+ CuO, Nb2O5+ Graphene, Nb2O5+ CuO + Graphene composite films to modify the properties of Ti6Al4V titanium alloy

Influence of Material Composition on Structure, Surface Properties and Biological Activity of Nanocrystalline Coatings Based on Cu and Ti

“…Thin films were prepared by pulsed DC magnetron sputtering [73][74][75][76][77][78][79]. Desired material composition was obtained by simultaneous sputtering (with the appropriate power) of several targets made of Cu and Ti [78,[80][81][82][83][84][85][86].…”

Insights into Different Reaction Behaviors of Propane and CO Oxidation over Pt/CeO2 and Pt/Nb2O5: The Crucial Roles of Support Properties

“…Regarding the O 1s XPS spectra (Figure b), three oxygen species (e.g., O a , O b , and O c ) are observed in the Pt/CeO 2 and Pt/Nb 2 O 5 catalysts. The component at BEs of 529.5–530.0 eV (O a ) is assigned to lattice oxygen species; , the component at BEs of 531.6–532.0 eV (O b ) is assigned to surface absorbed oxygen species, which is related to the existence of oxygen vacancies. , The component at BEs of 533.0 eV (O c ) is assigned to the surface hydroxyl group or carbonates . In addition, the content of O b species in Pt/CeO 2 catalyst (23.2%) is much higher than that of Pt/Nb 2 O 5 catalyst (2.4%).…”

Polyoxoniobates as molecular building blocks in thin films

“…This allows for the production of films that can be freely doped with different ions and at different ratios. Finally, while there is a range of existing methods for making metal oxide films, [29][30][31][32] not all scale well, or can be applied to a wide range of substrates. Sol-gel, 29 sputter deposition 30 or laser ablation methods 31,32 may suffer from issues of reproducibility and/or cost.…”

“…Sol-gel, 29 sputter deposition 30 or laser ablation methods 31,32 may suffer from issues of reproducibility and/or cost. 32 The use of polyoxometalates circumvent these limitations, while offering the possibility of heteroatom doped Nb 2 O 5 or Ta 2 O 5 to be fabricated through soft methods. Film preparation through spin-coating of benign, non-volatile, water-compatible precursors that can easily be made in bulk quantities, is thus a very appealing idea.…”
