Haematite particles of four different morphologies (polyhedral, platelike, needlelike and disk shaped) were synthesized by the hydrothermal method. The morphology average particle diameter (1.4, 7.4, 0.2, 0.12 μm, respectively) determined transmission electron microscopy combined with diffraction. haematite samples studied Mössbauer spectroscopy in temperature range 4.2–300 K. In all cases, a weak ferromagnetic (WF) phase was present above Morin 230 K found to coexist an antiferromagnetic...
Textile materials can be easily used as a support for the nano-decoration with active particles in order to gain new features such self-cleaning, antimicrobial efficiency, water repellency, mechanical strength, color change and protection against ultraviolet radiations. In this context, our present research reports fabrication characterization (physico-chemical analysis surface morphology) of cotton fabrics treated reduced graphene oxide decorated two types TiO 2 nanoparticles co-doped 1%...
TiO2-based photocatalysts were obtained during previous years in order to limit pollution and ease human daily living conditions due their special properties. However, obtaining biocompatible is still a key problem, the mechanism of toxicity recently received increased attention. Two types TiO2 nanoparticles co-doped with 1% iron nitrogen (TiO2-1% Fe–N) atoms synthesized hydrothermal at pH 8.5 (HT1) 5.5 (HT2), antimicrobial activity cytotoxic effects exerted on pulmonary dermal fibroblasts...
Our research was focused on the evaluation of photocatalytic and antimicrobial properties, as well biocompatibility cotton fabrics coated with fresh reused dispersions nanoscaled TiO2-1% Fe-N particles prepared by hydrothermal method post-annealed at 400 °C. The powders were characterized X-ray diffraction (XRD), Mössbauer spectroscopy photoelectron spectroscopy. textiles doped TiO2 scanning electron microscopy energy dispersive analyses, their effect trichromatic coordinates materials...
Co, Ni, Mn, Cr, and Cu substituted magnetites were prepared by the hydrothermal method at 300 °C, with concentrations ranging from 8.2% to 12.5%. Transmission electron microscopy determined average particle diameter 〈Φ〉 be in hundred of nm range morphological modifications induced various substitutions employed. Hysteresis loop measurements performed determine coercive field Hc, saturation magnetic moment ms. While Hc decreased increasing 〈Φ〉, shape was found play an important role...
