Abstract

The current research aims to present the structural characterization of Gd-doped ceria powders and ceramics, investigating the structural evolution resulting from cerium substitution with Gd across the entire composition range from 0 to 100 mol.% Gd2O3. Ce1-xGdxO2-x/2 powders with varying Gd contents (0 ≤ x ≤ 1) were synthesized using the ionic gelation method followed by thermal annealing. The resulting powders were subjected to high-temperature treatment to obtain ceramics. Characterization methods included X-ray diffraction (XRD) to identify phase composition and confirm the formation of Ce1-xGdxO2-x/2 solid solutions, infrared spectroscopy (IR) and scanning electron microscopy (SEM) for structural and morphological studies, and X-ray photoelectron spectroscopy (XPS) to evaluate the electronic structure. Comparative analysis of Gd-doped calcined powders and sintered pellets revealed the impact of thermal treatment on the structural features of the resulting solid solutions, elucidating the influence of gadolinium substitution. The novelty of this research lies in demonstrating the successful preparation of Ce1-xGdxO2-x/2 solid solutions via an alginate-mediated ion-exchange process and providing a detailed structural investigation over the entire range of dopant concentrations. This assessment highlights the feasibility for further research of these materials as suitable candidates for intermediate-temperature solid oxide fuel cells (IT-SOFCs) or catalyst applications.   Doi: 10.28991/ESJ-2024-08-05-01 Full Text: PDF

Abstract

The purpose of the research article is to identify the educational methods suitable for developing employee emotional intelligence. The focus was on the number of hours that small and medium sized enterprises are willing to invest in training their employees in emotional intelligence and on the benefits, i.e., changes in work outcomes as evaluated by respondents. The questionnaire method and interviews were used to obtain data from respondents, line managers, and education managers. Based on correlation coefficient calculations, brainstorming was identified as a frequently used method of active learning, which is related to the physical presence in the learning premises. The analysis of the responses of the respondents and their calculation using the correlation coefficient surprisingly showed that the lecture method gained great support and was considered by the respondents, i.e., managers and education managers, as very important to achieve the cognitive, affective, and psychomotor goals of education. Moreover, it was assessed as a method suitable for remote learning, i.e., for virtual educational spaces. Doi: 10.28991/ESJ-2024-08-05-023 Full Text: PDF
