PURPOSE To endow implants with both short- and long-term antibacterial activities without impairing their biocompatibility, novel Ti-Ag alloy substrates with different proportions of Ag (1, 2, and 4 wt% Ag) were generated with nanotubular coverings (TiAg-NT). METHODS Unlike commercial pure Ti and titania nanotube, the TiAg-NT samples exhibited short-term antibacterial activity against Staphyl...

A Ag/TiO2 nanocomposite, in which silver nanoparticles are highly dispersed in the uniformly sized pores of a cubic mesoporous TiO2 molecular-sieve film, has been fabricated.

The aim of this study was to develop a manufacturing protocol for large-scale production of doped titania radiosensitizing nanoparticles (NPs) to establish their activity under hypoxia and to produce a multimodal radiosensitizing embolic particle for cancer treatment. We have previously shown that radiosensitizing NPs can be synthesized from titania doped with rare earth elements, especially ga...

A ternary hybrid structure of one-dimensional (1D) silver nanowire-doped reduced graphene oxide (RGO) integrated with a CdS nanowire (NW) network has been fabricated via a simple electrostatic self-assembly method followed by a hydrothermal reduction process. The electrical conductivity of RGO can be significantly enhanced by opening up new conduction channels by bridging the high resistance gr...

Biomaterials releasing silver (Ag) are of interest because of their ability to inhibit pathogenic bacteria including antibiotic-resistant strains. In order to investigate the potential of nanometre-thick Ag polymer (Ag/amino-hydrocarbon) nanocomposite plasma coatings, we studied a comprehensive range of factors such as the plasma deposition process and Ag cation release as well as the antibacte...

Abstract This work focuses on improving the durability of Ni/yttria-stabilized zirconia (YSZ) fuel electrode-supported solid oxide cells under reversible operation mode by infiltrating nano-sized electrocatalysts into both electrodes. The resulting cell consists a CGO (Gd-doped CeO 2 ) scaffold-based oxygen electrode that is infiltrated with LSC (La 0.6 Sr 0.4 CoO 3-δ and CGPO (Gd, Pr-co-doped ...

In  this  reaserch,  photocatalyst  titanium  dioxide  was  doped  with silver  and modified  by  polyethylene  glycol  by  sol  gel method  and the  samples  were  characterized  by  X-ray  diffraction  (XRD)  and scanning  electron  microscopy  (SEM).  The  purpose  of  the  present study  was  to  evaluate  the  photocatalytic  bactericidal  effects  of prepared nanocomposite on human p...

ZnS nanoparticles (NPs) doped with ‎Ag‎, ‎Cu‎, ‎and AgCu were synthesized using hydrothermal‎ ‎method in water solution‎. ‎The NPS are characterized by X-ray diffraction (XRD)‎, ‎energy-dispersive‎ ‎X-ray spectroscopy scanning (EDX)‎, ‎scanning electron‎ ‎microscopy (SEM) and dynamic light scattering (DLS)‎. ‎The produced NPs have approximately hexagonal structure and a cubic zinc blended struc...

Pure ZnO, Ag doped ZnO and Ag-Fe co-doped ZnOwere preparedusing thermal evaporation. XRD analysis confirms that all layers present a hexagonal wurtzite structure; however, there is small shift in the peaks position due to thedistortion of film’s lattice. Scanning Electron Microscopy (SEM) reveals morphological variation surfaces doping. Ag:ZnO films have nanostructured surface, Ag-Fe:ZnO showed...

Ag-doped La0.67Sr0.33MnO3 thin films with various Ag concentrations were deposited on (001) LaAlO3 substrates at 400 ◦C by using a dual-beam pulsedlaser deposition system. The Ag-doped films show polycrystalline structure with epitaxial c-axis columns. These columns were composed of closely arranged polyhedra of size 10–15 nm, resulting from the enhanced stressinduced grain boundary diffusion. ...
