The inhibitory effect of gallium (Ga) ions on bone resorption and their superior microbial activity are attractive and sought-after features for the vast majority of implantable devices, in particular for implants used for hard tissue. In our work, for the first time, Ga ions were successfully incorporated into the surface of titanium metal (Ti) by simple and cost-effective chemical and heat tr...

In this paper, the impedance matching of flaky carbonyl iron was improved by surface modification with binary coupling agents. The microstructure, phase and electromagnetic parameters were detected Scanning electron microscope (SEM), X-ray diffraction (XRD) Agilent vector network analyzer, respectively. After agent applied, shape particle size (CIP) have changed significantly, whereas remained ...

This research is devoted to studying the radiation-protecting characteristics of calcium titanate (CaTiO3) perovskite-based ceramic material. The ceramics were made by solid-state reaction method (SSRM) and treated at temperatures 1300 °C, 1200 1100 °C. structural analyzed XRD FT-IR. results indicated a CaTiO3 phase formation with an orthorhombic structure. size crystallites was in range 27–36 ...

Calcium titanate (CaTiO3), a multi-metal oxide has received extensive attention in recent years, due to its unique structural features, high chemical stability, strong catalytic activity, inexpensiveness, low toxicity, and easy synthesis. In this work, we have focused our research on investigated the influence of Ca weight microstructure properties CaTiO3 films. films TiO2 nanotube templates we...

biomimetic method was used to apply hydroxyapatite (ha) coating onto ti6al4v cylinders. this process is a physicochemical method in which a substrate is soaked in a solution simulating the physiological conditions, for a period of time enough to form a desirable layer of the calcium phosphate on the substrate. in the present study, specimens were soaked in 5, 10 m solutions of naoh at temperatu...

a Titania (TiO 2) and sodium titanate nanostructures with controllable phases and morphologies were synthesized by hydrothermal method with titanium disulfide (TiS 2) as the starting material. Sodium 5 titanate nanobelts could be synthesized under a relatively low alkaline concentration (1 mol L-1 NaOH) and short duration (6 hours). At 3 mol L-1 HCl, rutile TiO 2 nanorods were synthesized. Anat...

Heavy metals are serious pollutants in aquatic environments. A study was undertaken to remove Cu, Cd, Ni, Pb and Zn individually (single metal system) and together (mixed metals system) from water by adsorption onto a sodium titanate nanofibrous material. Langmuir adsorption capacities (mg/g) at 10(-3)M NaNO3 ionic strength in the single metal system were 60, 83, 115 and 149 for Ni, Zn, Cu, and...

We tried to evaluate the carcinogenic risk of man-made mineral fiber based on the mesothelioma incidence in female F344 rats after intraperitoneal administration. Rats (female F344/ Nslc, 5-week-old, n=330) were observed for 2 years after the intraperitoneal administration of 5 to 20 mg of 9 types of the JFM (Japan Fibrous Material Research Association) standard fiber samples (glass wool, rock ...
