The paper presents the study of phase and structural behavior of pseudoternary compound (Ga1-x-yInxAly)2O3 with focus on the compositional cross-section where the x/y ratio is a fixed at 0.31/0.69. This specific ratio ensures that the average cation radius, equal to that of Ga3+ ions, remains unchanged. Through the combination of experimental XRD studies and DFT calculations, the stability region of the monoclinic phase within the Ga2O3–Al2O3–In2O3 ternary system was established. Detailed analysis of the crystal lattice parameters and unit cell volume of the monoclinic structure was carried out across a wide range of compositions. An empirical relationship was derived linking the monoclinic lattice parameters to the average ionic radius of the cations (Ga3+, Al3+, In3+) enabling prediction of lattice parameters in monoclinic (Ga1-x-yInxAly)2O3 solely from chemical composition. The experimental crystal structure studies and the electronic structure calculations suggest that in the monoclinic (Ga1-x-yInxAly)2O3 structure the tetrahedral positions of Ga1 atoms are preferentially occupied by Ga3+ and Al3+ cations, while the octahedral Ga2 sites accommodate a mixture of Ga3+, Al3+ and In3+ cations. Additionally, the presence of unidentified phase(s) was confirmed in the central region of the Ga2O3–Al2O3–In2O3 triangle. Comparison of the calculated optical absorption spectra and the Tauc-plots derived from the diffuse reflectance spectra indicate that the monoclinic (Ga1−x−yInxAly)2O3 compounds have a direct band gap.Supplementary InformationThe online version contains supplementary material available at 10.1038/s41598-025-21074-7.

This study evaluates the formation of ethical responsibility among master's students enrolled in the "Applied Physics and Nanomaterials" program. Recognizing the pivotal role of ethics in the evolving field of nanoscience, the research implements a three-phase methodology that integrates an Initial Ethical Responsibility Assessment, a facilitator-led Group Discussion, and a Retest Ethical Responsibility Assessment. The assessments are based on realistic scenarios reflecting ethical dilemmas that students may encounter in professional practice. This dual approach - combining quantitative assessment with qualitative analysis - provides a comprehensive understanding of students' ethical reasoning and decision-making. Results indicate varying levels of ethical responsibility, underscoring the need for more integrated ethics education in nanoscience curricula. The study contributes to ongoing discussions on the importance of ethics in scientific training, especially in high-impact fields such as nanotechnology. It offers educators a structured framework for embedding ethics into technical education, ensuring that future nanomaterials specialists are not only proficient scientists but also ethically responsible professionals. The article concludes with recommendations for enhancing ethics education in nanoscience through interactive, scenario-based, and discussion-centered learning methods.

<p dir="ltr"><span>In the context of the study, the essence of the psycholinguistic features of the use of Anglo-American words in youth slang was clarified. The definition of the concept of slang and psycholinguistics is revealed. A theoretical and methodological analysis of the work of researchers as a basis for the formation of trends in postmodern society has been carried out. In the course of the study, a linguistic analysis of concepts and terms characterising Ukrainian youth slang was carried out. The research problem is determined by close integration and globalisation processes. The theoretical significance of the research lies in the development of a neurolinguistic approach to the analysis of Anglo-American loanwords in slang; in expanding the idea of the psychologically real meaning of slangisms; when systematising data on the functioning of borrowings in slang, a technique is used that involves a comprehensive consideration of the research object. The work contributes to the study of the ethno-cultural specificity of the linguistic consciousness of speakers of the American variant of the English language and slang as its meaningful form. The article defines the trends of the neuropsychological aspect in the context of rethinking values and determining priority bases for the formation of neurolinguistic analysis of lexical units. In order to realise the research goal, the method of synthesis and analysis, integration, as well as research, descriptive and scientific methods were applied. The method of generalisation formed an idea of the neurolinguistic essence of English slang in speech and communication interpretations.</span></p><div><span><br /></span></div>

ABSTRACTThis article explores the understudied critical issue of life under military occupation, focusing on Berdiansk (Ukraine), a peaceful resort city now under occupation. While scholarly attention has been directed toward broader military and political consequences, the everyday experiences of people living in occupied cities have largely been overlooked. Berdiansk's transformation under occupation provides a poignant case for examining the phenomenon of “silence” in such cities—what it signifies. The study reveals hidden dynamics of life under occupation through indirect methods like oral interviews, social media analysis, and regional media outlets. This article contributes to urban studies by highlighting the resilience and adaptation strategies of occupied communities. It emphasizes the need for robust global discourse and action to restore sovereignty and revive community and urban life in these silenced cities.

The relevance of this study lies in the growing shift to online education for displaced universities due to war-related disruptions. The aim is to identify barriers faculty and students face in such institutions and propose strategies for creating a barrier-free educational environment. The study employs a survey-based method, analyzing responses from 224 students and 71 faculty members of a displaced Ukrainian university.Results highlight significant economic barriers, with 79% of students reporting financial difficulties affecting access to stable Internet, modern devices, and essential resources. Virtual isolation was noted by 79% of students as a challenge in maintaining social connections, while 78% cited reduced motivation characterized by the dominance of avoidance motives. Faculty reported psychological stress (85.6%), including anxiety (75%), tremors (54%), and sleep disturbances (45%). Organizational barriers, such as adapting practical courses to online formats and increased workloads due to asynchronous learning, were also prominent.These findings underscore the need for targeted strategies to address the barriers and promote inclusivity and effectiveness in online education. A comprehensive approach integrating institutional, pedagogical, and policy-level interventions is critical for overcoming these challenges.

This study examines the complexities of researching Ukraine’s occupied territories, where silence often acts as both a defense mechanism and a barrier to understanding. It addresses the causes of informational isolation, including censorship, fear of repression, and restricted access to independent sources. The paper highlights the methodological and ethical challenges researchers face, particularly in working with sensitive data and engaging with vulnerable populations. The roles of universities, citizen science, media, and NGOs are explored as crucial avenues for gathering fragmented but vital information and fostering a broader understanding of life under occupation. Emphasis is placed on integrating FAIR principles (Findability, Accessibility, Interoperability, Reusability) with CARE principles (Collective Benefit, Authority to Control, Responsibility, Ethics) to ensure data are both responsibly managed and ethically used. Combining analytical rigor with reflective narratives, this study advocates for interdisciplinary approaches and strategic collaborations that transcend academic boundaries. These efforts are vital for post-war recovery, reintegration, and developing socially inclusive and sustainable strategies that address the human realities of occupation.

The study presents an analysis of scientific works related to the process of activating the educational activities of future teachers of natural and mathematical disciplines in the context of digitalization of higher education and the formation of competencies for their implementation. A comparison of the common features and differences between our research and others conducted in related fields has demonstrated, on one hand, the relevance of the topic and, on the other, the insufficient development of the issue. The purpose of the study is to determine effective approaches and methods for using digital technologies to enhance student activity during learning, as well as to create favorable conditions for their active participation in the educational process. The research employs the method of analyzing scientific sources was applied and experimental exercises were examined. The results indicate that the integration of digital tools, particularly energizer exercises, into the learning process significantly contributes to the development of critical thinking, creativity, and the ability to solve complex problems, which are essential for successful learning. The use of innovative approaches activates students’ cognitive processes and forms key competencies necessary for successful professional activity in a digital society. The importance of adapting education to contemporary challenges is also emphasized, particularly in light of the transition to distance learning during the pandemic and the ongoing large-scale war, which requires educators to develop new strategies and approaches to ensure the effectiveness of the educational process.
