“…This value is among the best of the state-of-the-art Ag-based antibacterial materials (1.4, 3.8, 4.5, 6.3 μg Ag cm −3 ). 24–27 The effective antibacterial activity of Ag@Zn-MOF can be attributed to the homogenously dispersed Ag sites within the alkene-functionalized Zn-MOF, which maximizes the accessibility of Ag species and reduces the use of Ag.…”

“…Apatite nuclei are initiated once, the super saturation rises over the critical level necessary for heterogeneous nucleation of apatite. [11][12][13][14][15] The microstructure and crystallinity of TiO 2 or SiO 2 may be the important factors influencing the nucleation of apatite on the surface.16 XRD patterns of the TiO 2 and TS composite coating is shown in The developed nano TiO 2 and TS crystalline particles have higher surface charge densities 17 and readily absorb molecules or ions onto their surfaces in SBF in order to decrease the total free energy and to become more stable. 3 It can be further demonstrated by thermodynamic analysis that the interfacial tension also diminishes due to decrease in particle size.…”

The thermal decomposition process developed in the present work is a viable technique for the formation of a nano TS (TiO2-SiO2) composite coating on Ti substrate. The electrochemical experiments revealed that the developed coatings had high degradation resistance characteristics and high biomimetic growth characteristics. There was no degradation on the coating even when it was subjected to different extent of electrochemical polarization and anodic current impression. The biomimetic growth studies of these coatings were carried out without any alkaline treatment. Surface and topographical analysis including SEM and AFM were also carried after biomimetic growth. The results of elemental analysis of the SBF solution and electrochemical characterization carried out at different stages revealed that there was efficient apatite growth even without pre-alkaline treatment.

Porous titanium samples with a porosity of 1.34~15.54% were prepared by a spark plasma sintering (SPS) process at sintering temperatures of 800 °C, 850 °C and 900 °C, and a sintering pressure of 10 MPa. The microstructures and fracture morphology of the samples were investigated by scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses. The compressive strength and elastic modulus were likewise measured. The results showed that no new phase occurred after the samples were sintered, and the main phases were α phase of hcp structure. The porosity of the samples decreased significantly with the increase of sintering temperature. At 800 °C, the sample phase was dominated by equiaxed α. There were more irregular coarse pores in the samples. At 850 °C, the microstructure was mainly zigzag α, and the pores were finely and relatively uniform in distribution. At 900 °C, the sample’s structure transformed into a dense sheet-like α. The sample’s densities increased and the pores disappeared. The room temperature compression test showed that the porous titanium sintered by SPS had excellent compressive strength. The yield strength, compressive strength, compressive strain and elastic modulus were 81.85~122.36 MPa, 161.65~498.86 MPa, 36.75~59.97% and 2.79~4.22 GPa, respectively.
