CuBiO synthesized by thermolysis of a new Bi(III)-Cu(II) oxalate coordination compound, namely BiCu(CO)·0.25HO, was tested through its integration within carbon nanofiber paste electrode, namely CuBi/carbon nanofiber (CNF), for the electrochemical detection of amoxicillin (AMX) in the aqueous solution. Thermal analysis and IR spectroscopy were used to characterize a CuBiO precursor to optimize the synthesis conditions.

The oxalate precursor was synthesized through the redox reaction between 1,2-ethanediol and nitrate ion and characterized by chemical analysis, infrared spectroscopy, and thermal analysis. LaFeO obtained after the calcination of the precursor for at least 550-800 °C/1 h have been investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), and high-resolution transmission electron microscopy (HRTEM).

- - The study focused on creating ZnO and Co/Mg-doped ZnO thin films on TiAlV alloy substrates to enhance biocompatibility and antibacterial properties for use in implants.
- - The films were produced through spin coating and thermal treatment at 600 °C, with a doping ion concentration of 1.0 mol%, and were characterized for various properties including microstructure and antibacterial activity.
- - Results indicated that the thin films possessed a nanostructured form, demonstrating strong antibacterial effects and supporting cell adhesion and growth, with these properties varying based on the type of doping ions used.
Influence of Sintering Strategy on the Characteristics of Sol-Gel BaCeTiO Ceramics.
Nanomaterials (Basel)
November 2019
Single-phase Ce-doped BaTiO powders described by the nominal formula BaCeTiO with = 0.005 and 0.05 were synthesized by the acetate variant of the sol-gel method.

The morphological, structural and optical properties were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), -ray diffraction (XRD), Fourier Transform Infrared (FT-IR), UV-Vis and photoluminescence (PL) spectroscopy. The cytotoxicity and biocompatibility of EuHAp were also evaluated using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide)) assay, oxidative stress assessment and fluorescent microscopy.
