Summary: The spinel-type NiMn2O4 negative temperature coefficient (NTC) ceramic compound prepared by co-precipitation technique shows promising structure, microstructure, and transport properties for thermistors application, with improved electrical conductivity at higher temperatures. The observed microstructure is largely influenced by low-temperature synthesis and the presence of Mn3+ at octahedral sites.

Summary: The study found that Li/Mn doping increases the ferroelectric/paraelectric phase transition temperature and spontaneous polarization in ceramic structures, while also suppressing the formation of oxygen vacancies and increasing resistance, resulting in excellent high-temperature piezoelectric properties.

Summary: The effect of Dy3+ ion substitution on the structural, dielectric, and magnetic behavior of BiFeO3 ceramics prepared via the solid-state route has been investigated. The substitution of Dy3+ ion with Bi3+ results in a phase transformation and a reduction in crystallite size. High-temperature transient interaction between oxygen vacancies and Fe3+/Fe2+ ions was observed. The addition of Dy improves the magnetic and dielectric properties, making BiFeO3 a suitable choice for data storage media.

Summary: Ternary ceramics PIN-PSN-PT with morphotropic phase boundary compositions were prepared and their phase structure, dielectric, piezoelectric, and electromechanical properties were investigated. X-ray diffraction analysis confirmed the perovskite structure and MPB compositions in PIN-PSN-PT ceramics. The ceramics exhibited high Tr-t (90-110℃), T-c (296-306℃), and d(33) (530-550 pC/N), as well as high k(p) (approximately 0.67) and excellent thermal stability of piezoelectric properties. Moreover, the ceramics showed a remnant polarization P-r of around 40 mu C/cm(2) and a coercive field E-c of approximately 10 kV/cm. These results suggest that the present ceramics are promising as piezoelectric materials for high-temperature and high-power piezoelectric device applications.

Summary: This study compared two methods, adsorption and in situ incorporation, for preparing hybrid polyphenol/hydroxyapatite nanoparticles. The results showed that adsorption of polyphenols on pre-formed nanoparticles did not change their properties, while in situ incorporation inhibited hydroxyapatite formation but resulted in higher loadings. Most hybrid particles exhibited a burst effect followed by slow release over time.

Summary: The quaternary chalcogenide LiGaSiS4 was prepared through a high-temperature reaction and exhibits good thermal stability and a large band gap. The crystal structure of LiGaSiS4 is based on a three-dimensional framework and the optical properties are closely related to the characteristics of the chemical bonds.

Summary: The traditional solid state reaction technique was employed to synthesize piezoelectric materials of (K0.5Na0.5)NbO3 (KNN) and CS doped KNN ((0.94)K0.5Na0.5NbO3-(0.06)CaSnO3 (KNN-CS (94/06) and (0.96)K0.5Na0.5NbO3-(0.04)CaSnO3 (KNN-CS (96/04)). The addition of CaSnO3 into KNN was found to significantly enhance the electrical properties, particularly in the KNN-CS (96/04) composition.

Summary: Dense (Sr1-xCax)(2)(Ti1-xSnx)O-4 ceramics were synthesized and their microwave dielectric properties were studied. The dielectric constant was mainly influenced by the ionic polarizability, while the Qf value was associated with the amount of Sr3Ti2O7 secondary phase and lattice energy. The tau(f) value could be adjusted towards zero by enhancing the bond energy. The optimal microwave dielectric properties were achieved at x = 0.10.

Summary: Sb-doped S-Ga2O3 crystals were grown using the OFZ method, and they showed high quality according to X-ray diffraction and rocking curves. Raman spectra indicated Sb substitutions in the octahedral lattice. The carrier concentration, electronic mobility, and electrical resistivity of Sb-doped crystals varied with increasing Sb doping concentration. The S-Ga2O3 crystals had good transmittance in the visible region, but decreased in the infrared region due to the increased carrier concentration. Transmittance in the UV region was high, with a cutoff edge at 258 nm.

Summary: A comprehensive study was conducted on the AgCl0.25Br0.75 - AgI system to obtain non-toxic, non-hygroscopic materials for IR fiber optics and optoelectronics. The study revealed a homogeneity region with 0-16 mol.% AgI in AgCl0.25Br0.75 and a heterogeneity region with 16-98 mol.% AgI in AgCl0.25Br0.75 in the phase diagram. The materials synthesized within these regions showed variations in band gap, optical transmission range, and scattering properties.
