This paper reports nano-structured SiO2-TiO2 coatings using the sol-gel technique on 316L steel substrates. Nanoindentation, surface analysis and corrosion resistance tests were performed on different samples. The nanomechanical tests allowed to compare uncoated steel samples (Eavg = 193.24 GPa and mean hardness of 2.63 GPa and coated steel samples (Eavg = 287.38 GPa and mean hardness of 5.74 G...

By using Radio Frequency (RF) magnetron sputtering method, Pb(Zr0.5Ti0.5)O3 (PZT) thin films were deposited on Pt/Ti/ SiO2/Si substrates. Pt/Ti bottom electrode was fabricated on SiO2/Si substrates by magnetron dual-facing-target sputtering system. Phase and crystalline structure analyses of the PZT films were performed on an X-ray diffraction(XRD), Surface morphology, roughness and particle si...

Functionalized Fe nanoparticles (NPs) have played an important role in biomedical applications. In this study, metallic Fe NPs were deposited on SiO2 spheres to form a Fe/SiO2 composite. To protect the Fe from oxidation, a thin SiO2 layer was coated on the Fe/SiO2 spheres thereafter. The size and morphology of the SiO2@Fe/SiO2 composite spheres were examined by transmission electron microscopy ...

Silica (SiO2) nanoparticles are being progressively applied in various applications, including cosmetics, food technology, and medical diagnostics. Although crystalline SiO2 is a known carcinogen, the carcinogenicity of SiO2 nanoparticles remains unclear. Here, we assessed the cytotoxic effects and DNA injury induced by exposure to various dosages of SiO2 nanoparticles at 0-2400 mg/mL (0-3200 m...

2. C (H, E, B) is a function of the values Pr (X | B) and Pr (Y | Z ∩B) assume on the at most 16 truth-functional combinations X, Y, Z of E and H . 3a. If Pr (E | H ∩B) < Pr (F | H ∩B) and Pr (E | B) = Pr (F | B), then C (H, E, B) ≤ C (H, F, B). 3b. If Pr (E | H ∩B) = Pr (F | H ∩B) and Pr (E | B) < Pr (F | B), then C (H, E, B) ≥ C (H, F, B). 4a. C (H, E ∩ F, B)−C (H, E ∩G, B) is determined by C...
