“…The observed bands in the lower wavenumber region (below 750 cm -1 ) are associated with the vibration modes (A1g, E1g and E2g) corresponding to the SFO magnetic phase [13,14]. Therefore, it is noticed that the glass-ceramic characteristics are also confirmed from the Raman spectroscopy measurements whose dynamic response is governed by the contribution of the vibrational modes from both glass-matrix and SFO magnetic phase.…”

Bioactive ferromagnetic glass-ceramics composites have been prepared through the combination of the quenching and solid-state reaction (SSR) sintering methods, viewing their integration in biomedical applications. The material under study consists of a glassy system with the chemical formula (94-2x)SiO2−xNa2O−xCaO-6P2O5, which acts as host-matrix for the magnetic phase (strontium ferrite). The samples were obtained by a modified incorporation technique, where the magnetic phase, previously synthetized by the SSR method, was added to the glass-matrix in desired proportions. The physical properties were investigated considering the analysis of the X-ray diffraction as well as Raman spectroscopy techniques, both performed at room temperature. Results revealed the formation of partially crystallized bioglass-ceramics, with a strong influence of the magnetic phase on the crystallization kinetics, which suggests the obtained bioactive composites promising materials for clinical treatments.

Hexagonal ferrite (MFe12O19, M=Sr, Ba, Cu, Ni, Pb) is a kind of semiconductor material with excellent performance and an important magnetic material, with high chemical and thermal stability, low cost, simple preparation process, excellent optical, magnetic, wave-absorbing, dielectric, photoluminescence properties and catalytic activities have been widely used in broadcast communication, information storage, aerospace, automatic control, catalytic synthesis, medicine and biology and many other fields. This paper focuses on the application of MFe12O19-based ferrite in the field of photocatalysis, and further discusses the effect of preparation method on the photocatalytic activity of MFe12O19-based photocatalysts. The application of MFe12O19-based photocatalysts in the degradation of dyes, drugs and persistent organic pollutants (POPs) was deeply revealed, and the photocatalytic mechanisms of single-phase MFe12O19, ion-doped MFe12O19 and MFe12O19-based composite photocatalysts were also explored. The relationship between photocatalytic activity and photoluminescence properties of MFe12O19-based photocatalysts have also been investigated. This review points out the direction for further research on the application of MFe12O19-based photocatalysts in the field of photocatalysis.

“…The nucleating and growing rate of the particles can be subsequently controlled. EDTA has been used to synthesizing highly dispersed Fe 3 O 4 nanoparticles (27.9 nm), 14 uniform SrFe 12 O 19 magnetic nanoparticles (60 nm), 15 single-phase cubic spinel LiMn 2 O 4 nanoparticles, 16 etc. Till now, few attempts have been made for preparing AgCl nanoparticles by using EDTA as a coordination agent.…”

Single-size AgCl nanoparticles were successfully synthesized through a direct precipitation method with ethylene diamine tetraacetic acid (EDTA) as the complexant. Fourier transform infra-Red (FTIR), X-ray diffraction (XRD), scanning electron micro spectroscopy (SEM) and density functional theory (DFT) calculation were conducted to analyze the structure and morphology. Linear sweep voltammetry and cyclic voltammetry (CV) were used to evaluate the electrochemical activity. The kind of formed complexes between Ag + and EDTA in the solutions changes by varying pH values in the solution. The stability of the formed complexes differs from each other, which notably affects the nucleation and growth of AgCl particles in the solutions and subsequently the particle size and morphology of synthesized AgCl particles. The reactants concentration, temperature and C Ag+ /C EDTA ratio are also dominant to the particle size and morphology of synthesized AgCl particles. Single-size AgCl nanoparticles (75 nm) with spherical shape were synthesized. The AgCl electrodes prepared by synthesized AgCl nanoparticles show the highest current density of 15.2 mA/cm 2 at potential −0.2 V and excellent cathodic and anodic recycling properties, indicating that the AgCl electrode is suitable for use as the electrode for rechargeable seawater battery.
