Density functional theory calculation was conducted to determine the optoelectronic properties of bismuth titanate sillenite (Bi12TiO20) and perovskite-like (Bi4Ti3O12) structures. The lattice parameters were experimentally obtained from Rietveld analysis. The density functional perturbation theory approach was used with the standard Perdew-Burke-Ernzerhof functional and screened Coulomb hybrid...

Biomaterials are increasingly used for bone tissue regeneration because of their potential to overcome the morbidity caused by autologous grafts and allografts. A combination properties is required, as biocompatibility, osteoconductivity, good mechanical strength fracture toughness. In this research, a compound alumina matrix with calcium titanate phosphate proposed. Magnesium stearate was poro...

Magnetoelectric lead-free composite ceramic based on the piezoelecrtic Ba0.85Ca0.15Ti0.9Zr0.1O3 (BCZT) and magnetic NiCo0.02Cu0.02Mn0.1Fe1.8O4−d (NCCMF) has been obtained by solid state method using preliminarily synthesized solid-state precursors. X-ray diffraction measurements, microstructural, magnetic, dielectric, piezoelectric magnetoelectric studies have carried out. Impurity phases were ...

A new titanate coupling agent synthesized from polyethylene glycol (PEG), isooctyl alcohol, and phosphorus pentoxide (P₂O₅) was used for the modification of calcium sulfate whiskers (CSWs) and the preparation of high-performance CSW/poly(vinyl chloride) (PVC) composites. The titanate coupling agent (sTi) and the modified CSWs (sTi-CSW) were characterized by Fourier transform infrared (FTIR) spe...

A vertically aligned nanotube array of titanium oxide was fabricated on the surface of titanium substrate by anodization. The nanotubes were then treated with NaOH solution to make them bioactive, and to induce growth of hydroxyapatite (bone-like calcium phosphate) in a simulated body fluid. It is shown that the presence of TiO2 nanotubes induces the growth of a "nano-inspired nanostructure", i...
