Summary: Hydroxyapatite microtubes were synthesized through a bio-mineralization route by depositing hydroxyapatite nanoparticles on gelatin microfibers, followed by a sintering process. The synthesized microtubes had uniform tubular hollow structures with a diameter of 50-200 μm and were mainly constructed of apatite phase. Cytotoxic evaluation revealed that the microtubes were biocompatible with osteoblast MC3T3-E1 cells and supported cell attachment and proliferation.

Summary: In this study, porous hollow hydroxyapatite (HAp) microspheres were successfully prepared using chitosan microspheres as sacrificial templates. The microstructure, biocompatibility, and drug delivery properties of HAp microspheres were evaluated. The results showed that the HAp microspheres had a spherical morphology with a porous and core-shell structure. They exhibited good biocompatibility and could support the attachment and proliferation of osteoblast cells. Furthermore, the HAp microspheres could adsorb and deliver a model drug, tetracycline hydrochloride (TH), and retain its biological activity to inhibit the growth of bacteria.

Summary: Considering the different sources of hydroxyapatite (HA) synthesis and the need to explore their impact on the properties of HA-based scaffolds, porous HA/polymethyl methacrylate (PMMA)/zinc oxide (ZnO) tri-component composite scaffolds were fabricated using a modified gas foaming process. The properties of the scaffolds were investigated by varying the sources of HA and maintaining a constant composition of HA, PMMA, and ZnO. The results showed that the natural HA-based scaffolds had better chemical, mechanical, and biological properties compared to the synthetic HA-based scaffolds. The study concluded that the properties of composite scaffolds significantly depend on the parent material (HA), and the bovine bone-derived HA-based scaffold exhibited improved properties for bone cell growth and proliferation.

Summary: This study demonstrates the efficient utilization of phosphors in solid-state lighting and phosphor-converted light-emitting diodes through the synthesis of undoped and Li+ co-doped CaMoO4:Dy3+ nanoparticles. The characteristic emission lines from Dy3+ are achieved through energy transfer from the host to the dopant. The optical properties of the phosphors are improved by lithium co-doping, resulting in enhanced light output and excited state lifetimes. This work highlights the importance of lithium co-doping in enhancing the optical properties of phosphors.

Summary: The effects of simultaneous Sm and Mn substitutions on LaFeO3 nanoparticle at half-doping level were studied. The nanoparticle exhibited a single-phase structure with a size of 33 nm, and showed significant changes in magnetic behavior and non-ergodic phase at low temperatures compared to the parent LaFeO3. The improved exchange interactions among ions resulted from the altered Fe crystal environment and multiplicity due to the presence of Sm and Mn.

Summary: A series of Sm and Mn co-doped nanoparticles were synthesized to investigate the effects of rare earth ions and Mn on the structural, magnetic, and low temperature electronic behavior of LaFeO3. The nanoparticles exhibited a distorted orthorhombic crystal structure, and the presence of multiple oxidation states of Fe and Mn was confirmed. The modified nanoparticles showed a drastic magnetic disorder phase and a colossal dielectric response at low temperature. The conduction processes in the modified systems were identified as possible N-type and P-type polaronic conduction.

Summary: The influence of Pb-2(+) on the structural, dielectric, and magnetic properties of strontium hexaferrite (SrFe12O19) has been studied. Samples were synthesized using the ethylene glycol assisted sol-gel autocombustion technique, and their structures were analyzed using X-ray diffraction. The dielectric study showed that the dielectric constant and loss tangent decreased with increasing frequency and reached a steady value at higher frequencies. Similar behavior was observed in the doped samples, but with smaller values. The magnetization plots exhibited hysteresis loops, and doping resulted in a decrease in saturation magnetization and an increase in coercivity.

Summary: The study focuses on the development of (Y, Gd)F-3 nanophosphors doped with different concentrations of Eu3+ using a modified hydrothermal process. Analyzing the effects of co-doping rare earth activators on the lattice structure and morphology, the research indicates a tunable optical band gap due to substitutions. The photoluminescence emission spectra of the nanophosphors show intensity variations and fluorescence quenching, with potential applications in bio-labeling due to their longer decay time.
