Summary: Bismuth silicate with sillenite structure (Bi12SiO20) nanophase was prepared via melt-quenching technique in the Bi2O3-ZnO-SiO2 glass system. The replacement of ZnO by Bi2O3 was found to affect the glass transition temperature and crystallization temperatures. The heat treatment regimes and the addition of Bi2O3 influenced the crystallization behavior, with sillenite being enhanced. The prepared samples showed high transmission in the mid-infrared region, making them suitable for use in electro-optical instruments and as IR transmitting windows. The addition of Bi2O3 also improved the optical properties, with the samples exhibiting luminescence nature and having calculated optical bandgaps located in the semiconducting range.

Summary: In this study, Fe2O3-doped titania was synthesized and its effects on phase composition, crystallinity, magnetic, and optical properties were investigated. The results showed that high Fe content led to the formation of secondary phases and degradation of crystallinity. The SEM analysis revealed that the particles had a size of around 50 nm. The 2% Fe-doped titania exhibited superior performance in terms of crystallinity, emission intensity, dielectric constant, and magnetization, making it a promising material for magneto-opto-electronic device applications.

Summary: Strontium oxide (SrO) loaded borosilicate glass-ceramics were synthesized and the effect of loading on the phase and chemical durability of the matrix was investigated. The samples with increasing content of SrO showed a more pronounced ceramic phase, and Sr element was distributed homogeneously throughout the matrix. The normalized leaching rates of Si, B, Ba, Ca, Sr, and Ti were obtained after 30 days with 25 mol% SrO loading, suggesting that glass-ceramic wasteforms with a perovskite phase are advantageous for immobilizing short-lived radionuclides such as Sr.

Summary: Electrocatalysts are crucial for the development of environment-friendly energy conversion devices, but the high cost and scarcity of noble metals limit their large-scale application. This review article analyzes strategies for modifying materials without introducing other phases (self-modification) and introducing other phases (multi-phase modification) to design low-cost electrocatalysts. The article also discusses approaches for accelerating electron transfer on electrodes and provides a comprehensive summary and future perspectives on the practical application of these efficient electrocatalysts.
