“…The FTIR spectrum of the YO structure is also given in Figure 1b. The peak at 557 cm -1 , which supports the presence of Y-O bond, was determined in accordance with the literature [32]. The peaks observed at approximately 1510 and 1406 cm -1 can be considered as stretching peaks indicating the formation of citric acid complexes with Y ions [30].…”

In this study, graphene oxide (GO) was synthesized by the Hummers method starting from graphite. Also, the sol-gel method synthesized yttrium oxide (YO) and was characterized by FTIR, XRD, SEM, and TEM techniques. The sensor performance of the modified electrode against the paracetamol analyte was investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). As a result of the optimized voltammetric methods calculated the linear working range was 0.25-10.0 µM and the LOD value was 19.0 nM. With the DPV method, advanced analytical parameters such as stability, reproducibility, and selectivity were studied. Moreover, the performance of the new sensor to detect paracetamol in tablet real samples was examined.

“…In another study [48] they successfully utilized vacuum sintering to produce Y 2 O 3 ceramics doped with sintering additives. The addition of La 2 O 3 and ZrO 2 as additives during sintering at 1700 °C for 4 h resulted in a pore-free and homogeneous microstructure, with an average grain size ranging from 15.9 to 16.7 μm.…”

Metallic alloys' behavior at high temperatures, especially their response to corrosion and formation of protective surface layers, has long been a focus of scientific inquiry. Although certain alloy compositions require an initiation period before hot corrosion advances to the propagation stage, no combination of alloys can be considered impervious to hot corrosion indefinitely. The capacity of nickel-based materials to tolerate extreme circumstances such high temperatures, acidity, corrosion, and scratching is highly valued. However, they are unable to satisfy the strict demands of today's high-temperature applications. The durability of thermal barrier coatings (TBCs), which are prone to oxidation, rust, and degradation from sulphates and foreign object damage, has been the subject of recent study. For sophisticated ceramic materials exposed to high temperatures, hot rust degradation poses a considerable challenge. The main objective of this study is to investigate the effects of severe degradation on several advanced ceramic material types and their level of advancement. The purpose of the inquiry is to comprehend the deteriorating processes at the long term working condition, including the function of oxidation and liquid salts. Additionally, we investigate the effects of temperature, environment, and contact duration on the heated weathering behavior of earthenware. Finally, we discuss strategies for mitigating hot corrosion degradation in ceramics, such as protective coatings like new design of TBCs, doping, and composition optimization. This paper aims to offer a thorough understanding of the hot corrosion behavior of ceramics, which is crucial for developing durable materials suitable for high-temperature applications. Additionally, it explores the fabrication of protective coatings and addresses the challenges faced in this regard. The insights gained from this research can contribute to the advancement of resilient ceramic fabrics and the development of effective protective coatings.

“…Over the past few decades, mono-and polycrystalline ceramics have been in great demand due to their excellent chemical and physical stability with high transparency over a wide range of wavelengths. They are used for military use and in the semiconductor industry, for example, as components of transparent armor, window domes, and plasma etching chambers [1,2]. This study focuses on transparent Y2O3 ceramics, which have been attractive as a medium for use in tomorrow's high-power lasers and luminescent materials due to their higher thermal conductivity with lower thermal expansion compared to Y 3 Al 5 O 12 (YAG).…”

The paper is devoted to the changes in the X-ray luminescence spectra of nanoscale Y2O3 ceramics, namely the radiation associated with a self-trapped exciton. Additional heat treatment (annealing) of ceramic samples leads to changes in the exciton band of the spectra. These are a change in the shape and shift of the maximum of this band. Long-term irradiation of the samples by X-ray photons with an energy of 60 keV also led to changes in the exciton band. A theoretical model based on experimental data explains the changes in the spectra. The energy source of luminescence in this case is photoelectrons formed by energetic photons. Traps for these electrons are formed on the surface of submicrocrystals. Changes in the surface-to-volume ratio of crystals, as well as the frequencies of excited phonons and excitons are the basis for changes in the X-ray luminescence spectra of Y2O3 ceramics.
