Summary: This work reported the optical properties of polycrystalline Sr1-3x/2EuxTiO3 (x = 0.01-0.07) materials prepared by the sol-gel method. The microstructure of the Sr1-3x/2EuxTiO3 powders consisted of nanograins, with average particle size decreasing from 86.32 nm to 51.87 nm with increasing Eu amount. Optimized sintering conditions resulted in single-phase cubic SrTiO3 ceramics, which exhibited high purity and uniform distribution of chemical elements, ensuring good optical properties. The emission spectra of the Eu-doped SrTiO3 phosphor indicated orange-red emissions, making it a promising candidate for red-emitting components in solid-state light sources.

Summary: Erbium-doped silica films were synthesized using a two-step sol-gel methodology with acid and base catalysts. The samples with efficient emission were annealed at 800-900 degrees C and doped with 3-6% erbium. The internal structure of the films was influenced by annealing temperatures and doping concentrations. The proposed method shows promise for the synthesis of erbium-doped silica films with potential optical device applications.

Summary: The study investigated the influence of Sr concentration on the structure, surface morphology, particle size, microstructure, chemical durability, ion release, and in vitro mineralization of mesoporous bioactive glass nanoparticles (MBGNs). The interaction of MBGNs with simulated body fluid (SBF) resulted in the formation of crystalline hydroxyapatite (HA). The in vitro apatite-forming ability of MBGNs decreased with increasing Sr concentration. The MBGNs showed promising potential for applications in orthopedics, dentistry, wound healing, and drug delivery systems.

Summary: This study reported the sol-gel synthesis of Y3+ doped BCZY with different chelating agents, investigating their effects on thermal decomposition, phase formation, and morphology. Results showed that the molecular weight of chelating agents influenced the weight loss of intermediate compounds and the formation of BCZY crystals, leading to different crystal structures. The use of different chelating agents interacted with metal cations, causing the formation of Zr-cluster and Ce-cluster, which may explain the fluctuations in the elemental composition of the calcined powders.

Summary: Multiferroic nanocrystalline Bi1-xSrxFeO3 samples were synthesized using the sol-gel method and characterized through various techniques. The increase of Sr content led to a phase transition and reduction of impurities. Substitution of Bi3+ by Sr2+ ions generated oxygen vacancy equilibrium valence state in the samples.

Summary: In this study, highly crystalline bi-functional manganese-doped zinc silicate (Mn-doped Zn2SiO4) nanostructures were synthesized using a low-cost sol-gel route followed by solid state reaction method. Structural and morphological characterizations of the doped nanostructures were conducted using X-ray diffraction and high-resolution transmission electron microscopy (HR-TEM) techniques. Photoluminescence (PL) spectra showed strong green emission at 521 nm under 259 nm excitation wavelengths, with the intensity increasing with increasing Mn-doping concentration. The magnetic properties of the doped nanostructures were also investigated. These findings open up new possibilities for the application of Mn-doped Zn2SiO4 nanostructures in magneto-optical and spintronic devices.

Summary: In this study, the low-cost carbon powder obtained from PET bottles waste was investigated for the removal of Pb (II) ions from aqueous solution. The carbon sample was characterized and batch experiments were conducted to study the adsorption process. The results showed that the carbon powder had a maximum adsorption capacity of 97.95 mg.g(-1) for Pb (II) ions. The adsorption process followed a pseudo-second-order kinetic model and the Langmuir isotherm model provided the best fit to the experimental data. The study concludes that PET waste is an advantageous and effective adsorbent for removing lead from water.
