“…3B–D . Figure 3B shows that Ti2p XPS peak shows two peaks at binding energy values of 458.9 eV and 464.6 eV which are ascribed to Ti 2p3/2 and Ti 2p1/2, respectively (Fouad et al 2011 ). The energy distance between the two peaks is 5.7 eV, which is characteristic of Ti 4+ oxidation state of TiO 2 compound (Hariharan et al 2020 ).…”

In this work, the effect of using Ag-doped TiO2 nanopigments on optical, mechanical and antimicrobial properties of coated paper was explored. Furthermore, the long-term antimicrobial activity of the coated paper was examined for up to 25 years. Titanium dioxide (TiO2) nanoparticles have been synthesized and doped with different percentages of Ag nanoparticles (Ag NPs) using a simple wet chemical approach. The Ag@TiO2 modified nanopigments were in the form of nanorods with an average size of about 20 nm as observed from TEM images. Increasing Ag content from 0.01 to 1.0% showed an increase in the mechanical properties of coated paper in terms of tensile, stretching, tensile energy absorption and burst while preserving the optical properties. Moreover, the antimicrobial inhibition activity increased with increasing the Ag content. The 1% Ag@TiO2 showed a long-lasting antimicrobial effect against Staphylococcus aureus (S. aureus) Gram-positive bacteria even after 25 years of ageing (93.4% inhibition). Investigation of reactive oxygen species (ROS) generation and reaction mechanism of antimicrobial activity over Ag/TiO2 under visible light is proposed. These results suggest that Ag/TiO2 NPs can be potentially used as a disinfection coating for paper and improving its mechanical properties. Graphical abstract

Nd doped Titanium coating was applied on stainless steel 316L by DC sputtering method to investigate the corrosion behavior in simulated body fluid at 37°C. The characterization of coated surface was done by XRD analysis that shows the incorporation of coating peaks within peaks of substrate (SS 316L), SEM/EDS also used to identify the structure and elemental composition of coating layer and the results indicated the formation of titanium carbide with neodymium particles which distributed on the titanium thin film and the EDS analysis showed the presence of Ti, Nd, O and high percent of C. AFM analysis indicated the increasing in surface roughness from 52.20 nm to 176.7 nm after coating with more valleys and peaks in two and three dimensions images, as well as more resistant for wear after coating from Abbott-Firestone results. The results of corrosion measurement showed the more positive corrosion potential for coated surface and decreasing in corrosion current density to obtain protection efficiency equal to 97.11% due to ability of the coating layer to isolate the substrate from corrosive environment.

“…On the other hand, titanium carbide (TiC) is a very attractive material due to its interesting mechanical, chemical and physical properties. It is characterized by a high hardness and high melting point [4], excellent electrical and thermal conductivity, high chemical and thermal stability and good wear and corrosion resistance [5][6][7]. Owing to combination of properties this material has been extensively investigated and thoroughly used in many technological applications [7,8].…”
