Neodymium-based permanent magnets are strategic materials for the global energy transition, supporting technologies such as wind turbines and electric motors. However, the concentration of supply and the environmental impacts of rare-earth mining raise concerns about supply-chain security and technological dependence. This study analyzed the international scientific output on neodymium within the energy transition framework, identifying temporal trends, research areas, influential authors, and the geographic distribution of knowledge. The PROKNOW-C method was applied to the Scopus database, covering the period from 2004 to 2024. After filtering and standardization steps, 1384 documents were analyzed using VOSviewer to map networks of co-authorship, co-citation, and keyword co-occurrence. The results indicated a growth in publications after 2015, coinciding with intensifying debates on sustainability and technological innovation. These publications are concentrated around three main themes: energy efficiency in motors and technological advancements in wind turbine generators, circular economy strategies, and the development of alternative materials. Scientific output is led by China, the United States, and Japan. Ultimately, this mapping reveals that while the electromechanical application of neodymium is a consolidated field, there is an urgent need to foster research and public policies focused on recycling technologies to mitigate supply-chain vulnerabilities and ensure the material security of the global energy transition.

The growing demand for sustainable materials as alternatives to conventional petroleum-based plastics has accelerated research on alginate-based films. Alginate is a naturally occurring polysaccharide, mainly extracted from brown algae and widely used in the bioindustry due to its biodegradability, film-forming ability, biocompatibility, and functional versatility. However, a comprehensive understanding of global research trends and emerging directions in this field remains limited. This study presents a bibliometric analysis of global research on alginate-based films from 2001 to December 2024, aiming to identify key trends, collaboration patterns, thematic structures, and future directions. The dataset was retrieved from Scopus and analyzed using VOSviewer (v.1.6.20). A significant increase in publications has been observed over the past five years. The International Journal of Biological Macromolecules was identified as the leading journal. “Agricultural and Biological Sciences” dominated the field. China was the most productive country, while Jhong-Whan Rhim was the most prolific author. Jiangnan University was the most active institution. Keyword analysis revealed three themes: mechanical enhancement, food packaging, and biomedical applications. Recent trends indicate a growing focus on sustainable food packaging development.

In a post-consensus institutional landscape—where higher education systems face intensifying pressure to demonstrate strategic governance and measurable commitment to global sustainability mandates—understanding how the scholarly field of Education for Sustainable Development (ESD) has itself structurally evolved acquires both analytical urgency and policy relevance. This study maps the intellectual structure of Education for Sustainable Development (ESD) and institutional commitment in higher education through a PRISMA 2020-guided bibliometric analysis of 126 articles retrieved from Scopus for the period 2018–2025. Annual output rose from a single article in 2018 to 32 in 2025, with 46.8% of the corpus concentrated in the 2024–2025 biennium—a pattern indicative of rapid field maturation. Keyword co-occurrence analysis reveals a dual thematic architecture comprising four clusters: a Curriculum Innovation and Pedagogical Transformation axis and a strategic governance and institutional commitment axis. A notable pattern is a reorientation in the relative weight of research themes, evidenced by the growing density of terms such as governance, strategic approach, and institutional commitment in the recent literature. This governance-oriented cluster, consolidated by a core of prolific authors, shows a higher recent growth rate in co-occurrence frequency than the traditional curriculum axis. An emerging tendency toward disciplinary specialization—particularly in engineering education—and toward impact assessment is consistent with a gradual thematic consolidation of the field. The observed co-occurrence patterns are consistent with theoretical frameworks that associate scalable pedagogical innovation with institutional-level commitment and systemic governance frameworks aligned with the SDGs, although bibliometric data alone cannot establish this dependency. These patterns may signal a reorientation in the scholarly framing of ESD toward institutional design and governance questions, although confirming whether this reflects substantive epistemic change or shifts in publishing incentives requires evidence beyond bibliometric indicators.

This study aims to provide a comprehensive cross-regional bibliometric analysis of artificial intelligence (AI) research in East Asia and Latin America from 2020 to 2025. By quantifying publication trends, authorship, institutional productivity, collaboration networks, and citation impact, the research seeks to identify regional leaders, thematic clusters, and disparities in visibility and impact between these two regions. Design/methodology/approach; Scopus-indexed publications containing the phrases “artificial intelligence research” or “artificial intelligence innovation” in their title, abstract, or keywords were retrieved for the period 2020–2025. Inclusion criteria required at least one author’s affiliation in any of the fourteen specified countries across East Asia or Latin America. All document types (articles, reviews, conference papers, book chapters) were considered. Metadata were manually extracted from Scopus database ranking to identify the top-cited papers, most prolific authors, leading institutions, thematic and subject-area concentrations, and crossnational collaboration patterns. Findings; this bibliometric review clarifies the dynamic trajectory of AI research in East Asia and Latin America, revealing significant disparities in productivity, visibility, and thematic focus. The findings underscore the need for targeted investments in research capacity building, strategic international partnerships, and thematic realignment particularly for Latin America to enhance global visibility and align with emerging AI trends. Originality; by contrasting two understudied regions (East Asia vs. Latin America), we capture shifts in the AI landscape—specifically, the generative AI boom across subfields and regions that no single region or pre 2022 study can. By highlighting structural disparities in productivity, citation impact, and institutional support, it offers policymakers, funding agencies, and academic leaders novel insights. Full article

Heavy metal contamination in soils threatens ecosystem stability, agricultural productivity, and human health due to its persistence, toxicity, and ecological risks. Microbial remediation has emerged as a sustainable and cost-effective strategy, but the knowledge structure and research trends in this field remain insufficiently summarized. This study conducted a bibliometric analysis of publications on microbial remediation of heavy metal-contaminated soils retrieved from the Web of Science Core Collection from 2000 to 2025. VOSviewer (version 1.6.20), CiteSpace (version 7.0.R0), and the bibliometrix package (version 4.5.0) were used to analyze publication trends, major contributors, influential journals, and keyword evolution. The results showed that the number of publications increased continuously, with rapid growth after 2020. China, India, and the United States were the leading contributors, while Poland, Spain, and the United States played important bridging roles in international collaboration. Ravi Naidu was the most cited author, and Journal of Hazardous Materials was the most productive journal. Keyword analysis revealed a shift from pollutant degradation and microbial screening toward plant–microbe synergistic remediation, co-contaminated soil treatment, microbial community responses, and ecological risk assessment. Future research should emphasize multi-omics-based mechanisms, long-term in situ applications, and integrated evaluation frameworks. Full article

Background: Gender discrimination in sport remains a persistent global issue, reflected in women’s limited participation, leadership representation, media visibility, salary equity, and personal safety. These forms of discrimination also negatively affect athletes’ psychological well-being, mental health, and overall sports experience. Despite growing scholarly attention over the past three decades, a comprehensive quantitative synthesis of this research area has been lacking. Methodology: A bibliometric analysis of 397 peer-reviewed documents published between 1995 and 2026 was conducted using the Scopus database. Data were analysed through the Bibliometric R package 4.2.1 and Biblioshiny interface. Science-mapping techniques including keyword co-occurrence, thematic clustering, thematic evolution, and collaboration network analysis were combined with performance indicators such as annual publication output, leading sources, author productivity, and citation impact. Results: Scientific production increased markedly after the mid-2010s, involving 187 sources and 1106 authors, with rising collaboration and citation influence. Core research themes included gender inequality, leadership exclusion, media representation, harassment and abuse, and structural discrimination in sports systems. Importantly, many of these themes are directly linked to reduced athlete well-being, including increased stress, anxiety, and decreased participation. Recent thematic developments highlighted intersectionality, safeguarding, inclusion, governance, and athlete welfare. Conclusion: Research on discrimination against women in sport has evolved into a multidisciplinary, policy-relevant field. Addressing gender discrimination is essential not only to achieving equity but also to improving athletes’ subjective well-being and long-term participation in sport. However, significant gaps remain, particularly in Global South contexts and intervention-based studies, indicating the need for stronger evidence-driven strategies to advance gender equity, inclusion, and ethical governance in sport.

The paper discusses how sentiment analysis can support urban planning and public health by linking environmental features to well-being and explores emerging methodological trends like deep learning, multimodal approaches, and context-aware models. Overall, it maps the field’s intellectual landscape and argues in future directions for human-centered, data-driven urban decision-making. Full article

Background/Objectives: Dental implant research has expanded substantially over recent decades, yet the characteristics of its most influential publications remain insufficiently defined. This study aimed to analyze highly cited dental implant research to identify global publication patterns, leading contributors, and major research themes. Methods: Publications indexed in the Web of Science Core Collection (SCI-EXPANDED) up to 1 May 2025 were retrieved. The analysis was restricted to WoSCC and used a fixed citation threshold; citation normalization and network analyses were not performed. Highly cited publications were defined as those with TC₂₀₂₄ ≥ 100 citations. A total of 1599 highly cited publications were identified; after application of the “front page” filter, 1324 implant-related documents remained, and 1016 original research articles were included in detailed bibliometric analyses. Citation indicators (TC₂₀₂₄, CPP₂₀₂₄) and authorship metrics (FP, RP, IP, CP, SP, and APP) were evaluated. Temporal trends, keyword frequency, and Y-index analysis were applied to assess research development and author contributions. Results: Publication output demonstrated steady growth, with peak citation impact observed after approximately 16 years. Research was primarily concentrated within dentistry, oral surgery, and biomedical-related fields. The United States and several European countries accounted for the majority of highly cited publications, with internationally collaborative articles showing higher citation impact than single-country publications. Keyword analysis identified four major research themes: biological integration, implant materials and surface characteristics, clinical treatment strategies, and peri-implant diseases. Conclusions: Highly cited dental implant research is characterized by strong representation of biological, material, and clinical domains. These findings should be interpreted as WoSCC-based citation patterns rather than definitive evidence of clinical impact, methodological quality, or global research priorities. Full article

Marginal land refers to areas where environmental constraints prevent cost-effective production; driven by global energy and food security strategies and greenhouse gas reduction targets, its potential productivity has garnered significant attention. However, macro-level and data-driven knowledge graph analyses remain scarce. Therefore, this study employed VOSviewer, Bibliometrix R, and CiteSpace to conduct a bibliometric analysis of 2535 Web of Science Core Collection documents (1995 to 2025). Findings reveal that: (1) The research is split into four stages—early exploration, fluctuating development, rapid growth, and stable output, peaking at 191 papers in 2021. (2) The collaboration of authors and institutions has reached an initial scale but remains relatively weak, with Lewandowski and the Chinese Academy of Sciences occupying the core of the co-authorship network. The United States (N = 501) ranks as the top-producing country. France (MCP% = 56.8%) leads in international collaboration intensity, and US—China cooperation is the most frequent. (3) Journals primarily focus on environmental science and agronomy, with Global Change Biology Bioenergy leading with 109 publications. (4) Through consolidating core keywords like “marginal lands,” “biomass,” and “productivity” into four perspectives: technological/model interventions, farmer behavioral choices, natural baseline conditions, and theoretical understanding, this study constructs a comprehensive framework to help research become sustainable.

The family Asphodelaceae, particularly the genera Asphodelus L. and Asphodeline Rchb., includes Mediterranean wild plants of ecological, agronomic, and phytochemical importance. Yet, their applied scientific studies remain fragmented and lack synthesis. This study provides the first bibliometric analysis of applied agronomic, ecological, and phytochemical research on these genera, integrating a transparent and reproducible framework. Publications indexed in the Scopus database from 1987 to 2026 were systematically screened. A sensitivity analysis of the search string progressively reduced the corpus from 1797 taxonomy-only records to 149 after applying intervention, outcomes, and exclusion criteria, of which 64 studies met the final inclusion criteria (43% inclusion rate). Bibliometric analysis was performed using Bibliometrix and VOSviewer. The final dataset spans 57 sources, with 265 contributing authors, an average of 4.95 authors per paper, and an international collaboration rate of 22.15%, highlighting the interdisciplinary nature of the field. Scientific production shows a gradual increase over time, with peaks after 2019, although citation impact remains uneven (mean 15.23 citations per document) and concentrated in a few highly cited studies. Research is geographically clustered along a Mediterranean–South Asian axis, with Italy emerging as the main hub of citation impact and collaboration. Keyword analysis identifies four main thematic clusters, revealing a progressive shift from early ecological and weed–crop interaction studies toward phytochemistry, plant extracts, flavonoids, and antioxidant activity. Despite this growth, substantial gaps persist in agronomy, domestication, and large-scale cultivation, limiting the translation of these species into viable crops. The present analysis is therefore motivated by the need to clarify the current level of scientific knowledge on these species and to assess their potential for future domestication. In this context, identifying research gaps is essential not only for guiding interdisciplinary studies but also for supporting the development of value chains and processing pathways aimed at the sustainable valorisation of these underexplored Mediterranean species.

Background: Sleep apnea is identified and treated less frequently among racial and ethnic minorities. Objective: The purpose of this systematic review was to examine disparities among racial and ethnic minorities and to understand the reasons for poor sleep health. Methods: The authors conducted a literature search using PubMed and Cochrane Library databases, last accessed in September 2025, using regular and MeSH keywords. A total of 123 articles were identified. PRISMA guidelines were followed, the PICO framework was applied, and the inclusion criteria were based on studies conducted in the past 10 years. After quality assessment, 18 studies were included for in-depth analysis. Results: The 18 studies included meta-analyses and observational cohort studies. In total, 51,489 patients were represented. Studies revealed that sleep apnea is underdiagnosed and undertreated in ethnic minority populations. Resident location, gender, economic status, and marital status also play an important role. One study noted clinically insignificant differences in positive airway pressure requirements between black and white populations. Nocturnal hypertension and increased left ventricle size are also observed in untreated sleep apnea. Given the heterogenous nature of the studies, quality risk assessment was not possible, which is a limitation of this study. Conclusions: Sleep apnea is underdiagnosed and undertreated among ethnic minorities. Factors such as ancestry, comorbidities, social determinants, geography, and healthcare access drive global inequities. Further sleep apnea phenotyping may be of value in planning treatment strategies. Full article

It is known that a significant portion of global carbon dioxide (CO₂) emissions originate from concrete production. However, construction and demolition activities result in a considerable amount of construction and demolition waste (CDW). The proper recycling of CDW is important in terms of conserving natural resources and ensuring sustainability. A significant amount of recycled concrete aggregate (RCA) is obtained from the recycling of CDW. Many researchers have contributed to reducing carbon emissions by conducting studies on RCA. However, the fact that recycled aggregates (RAs) are obtained from different construction wastes is the biggest obstacle to generalizing the studies in the literature. This study aims to identify machine learning (ML) models that can reliably predict the compressive strength of concrete produced with recycled concrete aggregates (RCAs) and to evaluate the impacts of their use. In this study, keywords (15) obtained from articles (7953) selected from Web of Science were searched in the Scopus database. The selected studies (397) were analyzed using VOSviewer (version 1.6.20) software to identify leading institutions, countries, authors, sources, fields, gaps, challenges, and trends related to the use of recycled aggregate in concrete. This study not only has a theoretical structure but also makes a significant contribution to the literature by offering practical recommendations for field applications. This is the most important feature that distinguishes this study from other research. This study also promotes the use of RAs in concrete to reduce CO₂ emissions and encourages its sustainable use in the construction sector. Full article
