Uysal, Turan; Supriyatna, Yayat Iman
Rare-earth elements (REEs) are geologically widespread, but their mining and especially processing are concentrated in a small number of countries; as demand grows, some specific REEs may face supply shortages in the near future. Consequently, owing to their economic potential even at low concentrations, ability to provide alternative supply opportunities, and process development potential, various countries are conducting studies on REE production from secondary geological sources such as high-silica bauxite ore. This study provides a detailed examination of aluminum (Al) and REE recovery from bauxite ore, emphasizing sustainable utilization of these resources. In this context, the study presents the technological evaluation potential of these deposits in the context of modern demands, the acquisition process, and an analysis of the main technical difficulties in this process. Furthermore, the application of both mechanical and thermal activation methods in conjunction may prove more economically viable and environmentally sustainable by reducing the temperature requirements of fossil fuel-consuming heat treatment. The development of sustainable Al and REE recovery technology from bauxite ore is of significant importance, not only in terms of mitigating supply risk but also as an alternative source for REE production.

İncele - MakaleAçık Erişim2026Scopus SJRQ2Selective Determination of Trace Co(II) and Cu(II) in Food and Environmental Matrices via Carrier Element-Free Coprecipitation Using a Novel Thiosemicarbazone-Derived Schiff Base
Bulut, Volkan N.; Demirci, Hamit; Ozdes, Duygu; Gundogdu, Ali; Bektas, Hakan; Soylak, Mustafa; Duran, Celal
A carrier element-free coprecipitation (CEFC) method was developed for the preconcentration and determination of trace Co(II) and Cu(II) in environmental and food samples using a novel thiosemicarbazone-derived Schiff base ligand (MBITAH). Unlike conventional coprecipitation approaches, the proposed strategy eliminates the need for inorganic carriers, reducing potential interferences and improving selectivity toward the target analytes. Under optimized conditions (pH 7.0, 1.5 mg ligand), quantitative recoveries were achieved with limits of detection of 1.16 and 0.79 µg L⁻1 for Co(II) and Cu(II), respectively. A preconcentration factor of 50 enabled sensitive determination by flame atomic absorption spectrometry (FAAS) with good precision (RSD ≤ 3.7%). The method exhibited good tolerance toward common matrix ions and was validated using certified-reference material (CRM-SA-C Sandy Soil C) and spike/recovery tests, showing agreement with certified values (p > 0.05). Its applicability was demonstrated in sea water, stream water, and food samples (red lentil and bulgur), confirming reliable performance in complex matrices. Compared with previously reported approaches, the proposed CEFC method offers a favorable balance between analytical performance, simplicity, and cost-effectiveness. In addition, greenness assessment using the AGREE tool yielded a score of 0.45, indicating a moderate-to-good level of environmental friendliness.

Erust, Ceren; Uysal, Turan
The use of bauxite-related shales as a secondary source for the extraction of rare earth elements (REEs) is very important to meet the raw material supply, which is the keystone of advanced technology applications. This study presents the investigation into the recovery of REEs from Kızıldağ shale ore and the potential utilization of its leach residue as a silica source. Mineralogical analysis revealed that the ore predominantly consists of paragonite, muscovite, quartz, pyrophyllite, and calcite. Calcined ore was subjected to acid leaching, and the resulting pregnant solution was purified using solvent extraction to separate from aluminum the ∑REEs with a content of 1887.35 ppm. Optimal solvent extraction conditions 1.5 M D2EHPA, 50% O/A ratio, pH 1.5, and 15-minute mixing time achieved 95% total REE extraction, with efficiency in the order Pr > La > Nd > Ce > Dy > Y > Sc. To purify Al from the Fe- and K-rich solution post-SX, electrolysis was performed, resulting in 97.16% precipitation efficiency of Al as Al(OH)3 at pH 5. The precipitate was subsequently roasted at 1100°C to produce α-alumina with 75.2% Al2O3 content. These findings confirm the technical feasibility of recovering REEs and producing coarse-purity alumina from Kızıldağ shale ore.

Olgun, Oğuzhan; Demirel, Çağatay; Demirel, Uğur
This study examines the contemporary manifestations of George Gerbner’s Cultivation Theory within the Turkish media landscape by analyzing the relationship between televised representations of violence and digital audience reception. Adopting a mixed-methods research design, the study first conducts a structured qualitative content analysis of 15 selected episodes from three popular Turkish TV series (Camdaki Kız, Sadakatsiz, and Son Yaz) to categorize and quantify various forms of violence. Subsequently, a large-scale computational emotion analysis is performed on 74,478 YouTube comments associated with these episodes using two transformer-based Turkish language models (KUBI and TREMO). The content analysis findings reveal a high prevalence of emotional and psychological violence (61.3%) across all series, followed by physical violence (29.9%), suggesting that mediated harm is increasingly represented through relational and verbal conflict. The computational analysis suggests that these narrative patterns are associated with a high-arousal and largely negative emotional environment in audience discourse, especially around anger and sadness. Notably, while traditional cultivation research emphasizes fear as a primary outcome (Mean World Syndrome), this study finds that digital reception is characterized more by outward-facing anger and moral disgust than by internalized apprehension. The results are consistent with the interpretation that the “seeds” of television cultivation continue to circulate within networked media ecologies, where televised conflict is publicly interpreted and emotionally negotiated through collective digital interaction. By bridging the gap between screen reality and platformed discourse, the research provides a comprehensive framework for understanding the long-term affective impact of Turkish television narratives in the digital age.
- MakaleYalnız künye2026Scopus SJRQ1A numerical case study on distinct inerter-based TMD configurations for SDOF structures under near-fault and far-fault ground motions
Araz, Onur; Abdo Saif, M.M.
This study presents a comprehensive optimization and performance evaluation of three distinct inerter-based tuned mass damper (TMD) configurations (C3, C4, and C6) for seismic vibration control. The optimal parameters for three different structural damping ratios (0%, 2%, and 5%) and a wide range of mass ratio (0 to 0.1) suitable for practical applications are determined in the frequency domain using the Sequential Quadratic Programming (SQP) algorithm to minimize the displacement response. To bridge the gap between complex optimization and practical engineering, novel empirical design formulas are proposed, enabling researchers to determine optimal parameters for C3, C4, and C6 configurations without requiring exhaustive computational effort. Unlike previous studies, the study presents a rigorous validation of inerter effectiveness through an extensive suite of 160 ground motions, providing a granular comparison of performance under near-fault excitations versus far-fault records. Results demonstrate that while inerter-based systems significantly outperform classical TMDs in the frequency domain, their comparative superiority in the time domain is more bound, with average response reduction improvements of approximately 5%. The inerter-based TMDs exhibit the highest efficiency in mitigating kinetic energy, followed by displacement and acceleration. Notably, the effectiveness of the control systems is found to be highly sensitive to ground motion characteristics and structural damping, where higher damping ratios consistently lead to reduced control performance. Considering the trade-off between seismic efficiency and mechanical simplicity, the C6 configuration is identified as the most viable solution for structural protection.

Kaya, Hacer; Kamiloğlu, Aybike
This study investigated the influence of the consumption of hawthorn (Crataegus tanacetifolia) fruit vinegar (HFV), a fermented product, on meat quality and gut microbiota in broiler chickens under cyclic heat stress (HS). A total of 300 one-day-old male Ross 308 chicks were divided into six groups with five replicates of ten birds, following a 2×3 factorial design with two temperatures (24 and 35°C) and three HFV supplementing levels (0, 2, and 4 mL/L) after one-week acclimation. Broilers in the thermoneutral groups were kept at 24°C, while HS groups experienced 35°C for 8 hours daily from day 21. Feed and water were provided ad libitum under a 24-hour lighting program. HS increased breast pH, reduced b* color value, raised ΣSFA and ΣMUFA levels, and lowered ΣUFA and ΣPUFA ratios. Supplementing 4 mL/L HFV increased breast L* color value and ΣSFA level while reducing ΣUFA ratio. The 2 mL/L HFV dose decreased ΣMUFA and increased ΣPUFA levels. Overall, HFV supplementation improved meat quality and beneficially altered fatty acid composition in heat-stressed broiler breasts. These results suggest that HFV supplementation may be a practical natural additive for broilers under cyclic heat stress and provide new evidence regarding its combined effects on meat quality and intestinal microbiota.

Bağci, Uğur; Alpteki̇n, Hasan Kerem; Hatik, Sefa Haktan; Aydin, Emine Büşra
Backgorund: To investigate the effect of a speleotherapy environment on spirometric parameters in smokers and to compare the outcomes with those of the same yoga-based breathing exercise program performed in a standard clinical setting. Methods: This randomized controlled clinical trial included 60 adult smokers aged 18–65 years who were allocated to a speleotherapy group (n = 30) or a control group (n = 30). Both groups received the same physiotherapist-supervised yoga-based breathing exercise program for 6 weeks, twice weekly, in 50-minute sessions; the only difference was the intervention setting. Forced vital capacity, forced expiratory volume in 1 s, peak expiratory flow, and forced expiratory volume in 1 s/forced vital capacity were assessed at baseline, week 3, and week 6. Physical activity, functional exercise capacity, and quality of life were also evaluated. Data were analyzed using linear mixed-effects models with group, time, and group × time interaction as fixed effects and participant as a random effect. Results: Both groups showed improvements over time in spirometric and secondary outcomes. In the linear mixed-effects model analysis, the primary spirometric outcome, forced expiratory volume in 1 s, showed a significant group × time interaction in favor of the speleotherapy group. Significant group × time effects were also observed for 6-minute walk distance and selected quality-of-life domains, whereas broader spirometric superiority across forced vital capacity, peak expiratory flow, and forced expiratory volume in 1 s/forced vital capacity was limited. Conclusion: The findings suggest that the treatment environment may influence selected respiratory and functional outcomes in smokers. Yoga-based breathing exercises were associated with improvements in spirometric outcomes in both settings. The additional effect of the salt-cave environment on respiratory outcomes was limited, with a significant between-group difference observed only for forced expiratory volume in 1 s. The salt-cave setting may also be associated with greater improvements in functional capacity and selected quality-of-life outcomes, but broader pulmonary benefits or an independent speleotherapy effect cannot be concluded from the present findings.

Can, Aysun Akçakaya; Demirağ, Hatice; Hintistan, Sevilay
OBJECTIVES: To examine the effects of live and robotic cat-assisted therapies on chemotherapyinduced symptoms and happiness levels in patients with cancer. SAMPLE & SETTING: 45 patients were randomly assigned to live cat therapy, robotic cat therapy, or control groups in a university hospital. METHODS & VARIABLES: Data were collected between June 1 and September 1, 2023. Patients in therapy groups interacted with a live or robotic cat for 20 minutes twice weekly for three months. RESULTS: Although the live cat therapy group had higher median happiness scores than the robotic cat therapy group, differences in happiness and symptom scores between groups were not statistically significant. Both therapies alleviated chemotherapy-induced symptoms and enhanced emotional well-being, with robotic cat therapy showing slightly greater overall effectiveness. IMPLICATIONS FOR NURSING: Robotic pet therapy offers a feasible alternative where live animalassisted therapy is impractical. Integrating these therapies into oncology nursing can enhance symptom management and psychological support, promoting holistic, patient-centered care.

Pilatin, Abdulmuttalip; Ayaydın, Hasan; Soto, Gonzalo Hernández; Pala, Fahrettin
Foreign direct investment inflows are an important factor in the development of countries. Rising FDI can cause unexpected environmental consequences by changing technology use or energy consumption. The study examined the relationships between fossil energy consumption, carbon emission rate, and FDI for 27 European Union countries in the period 2006–2021. In addition, for the first time in this study, EU countries were divided into two according to their income levels and re-analysed. Panel data method and robust Driscoll and Kraay (1998) estimator were used in empirical analyses. The research findings show that a one-unit increase in FDI across EU countries results in a 0.055% increase in GDP and fossil fuel consumption, respectively, and a −0.155% decrease in pollution. These results support the pollution halo hypothesis, which posits that foreign direct investment reduces environmental degradation. The research findings support the pollution halo hypothesis, which states that FDI reduces environmental degradation. It also confirms that the EKC hypothesis, which states that there is an inverted U-shaped relationship between pollution and GDP, is valid in 27 EU countries. However, it has been determined that the pollution haven hypothesis is valid in low-income EU countries. Low-income EU countries should encourage more foreign investment in technology-intensive and environmentally friendly areas and develop various environmental regulations in this direction. The results obtained from the research are expected to provide benefits and insights to policy makers, researchers, and industrialists to increase environmental awareness. The results suggest that low-income EU countries should encourage technology-intensive and environmentally friendly investments, improve green financing and investment conditions, and develop regulations to strengthen environmental standards, so that they can limit environmental degradation while preserving the general welfare-enhancing benefits of FDI.

- MakaleAçık Erişim2026Scopus SJRQ1Structure-Dependent Triglyceride Protection of Freeze-Dried Lactiplantibacillus plantarum: Storage Protection Window, Lipid Oxidation, and Stress Adaptation
Sun, Zheneng; Zhang, Nan; Wang, Xiaomai; Wei, Xinyao; Ozturk, Samet; Liu, Shuxiang
Lipid-rich matrices can protect probiotics by limiting direct exposure to moisture, oxygen, and gastrointestinal stressors. However, triglycerides are chemically dynamic during storage, and differences in fatty acid structure and oxidation susceptibility may determine whether they exert protective or detrimental effects. In this study, tricaprylin, triolein, and trilinolein were evaluated as post-drying lipid storage matrices for freeze-dried Lactiplantibacillus plantarum 124 during storage at 25 °C, and 37 °C was used to accelerate lipid oxidation. Survival during storage, fatty acid chain retention, oxidation-derived products, stress tolerance, qualitative confocal imaging of membrane-integrity patterns, and transcriptomic responses were analyzed. After 30 d at 25 °C, log reductions were 0.30, 0.24, and 0.24 log10 units in the tricaprylin, triolein, and trilinolein groups, respectively, compared with 0.60 log10 units in the oil-free control, defining a common protective window. Tricaprylin showed the highest fatty acid chain retention, whereas trilinolein exhibited the greatest loss and strongest oxidative change. GC–MS detected no representative oxidation-derived products in tricaprylin, while unsaturated triglycerides generated dimethyl azelate and methyl 9-oxononanoate. Cells recovered from the protective window showed improved acid and bile tolerance, with survival increasing from 30.48% to 53.43–55.65% and from 14.85% to 22.49–27.79%, respectively. Confocal imaging further showed better-preserved membrane-integrity patterns in the triglyceride-treated groups after acid exposure. Transcriptomics indicated enhanced transport, redox, DNA-related, and cell-envelope responses, accompanied by reduced translation and growth-associated metabolism. Within the experimental conditions tested, these results suggest that triglyceride-associated attenuation of viability loss varies among triglyceride systems and across storage stages, while excessive oxidation of unsaturated triglycerides may weaken probiotic stability.

Aydin, Aydanur; Bağcivan, Gülcan; Özkan, Aleyna
Background: Despite its growing presence in healthcare settings, research on the effectiveness of virtual reality (VR) interventions for symptom experience of patients with cancer remains varied and requires a comprehensive synthesis to reach definitive conclusions. Objective: This systematic review and meta-analysis aimed to assess the effectiveness of VR interventions in managing anxiety among individuals diagnosed with cancer. Methods: A comprehensive search of Ovid MEDLINE, PubMed, CINAHL, Web of Science, and Scopus databases was conducted for studies published from 2000 to November 2025. Publications were evaluated by independent reviewers for inclusion. The methodological quality of the included studies was assessed via Joanna Briggs Institute (JBI) critical appraisal tools for randomized controlled trials and quasi-experimental studies. Results: Twenty-one publications satisfied the requirements for review inclusion. The meta-analysis demonstrated that VR-based interventions were significantly effective in the management of patients’ anxiety, yielding a moderate-to-high effect size (SMD = −0.793, 95% CI = −1.403 to −0.184; Z = −2.551; p = 0.011). Most studies reported statistically significant decreases in anxiety scores across various cancer types, including breast, prostate, and ovarian cancers. No major side effects were reported, although minor instances of cyber sickness were managed by adjusting session durations. User satisfaction was exceptionally high, with satisfaction scores reaching 4.47/5 and 7.35/10. Implications for practice: The results support the use of VR as an effective and safe non-pharmacological intervention for anxiety management. The findings highlight the potential for VR to be integrated into routine oncology nursing and palliative care to improve the patient experience during stressful treatments like chemotherapy. Conclusion: VR-based interventions are an effective, safe, and highly acceptable approach for managing anxiety in patients with cancer. Further research is needed to support wider clinical implementation and to investigate the potential benefits of VR for other physical and psychological symptoms over longer follow-up periods.

- MakaleAçık Erişim2026Scopus SJRQ1The mediating role of attitudes in the effect of human and environment-centered value orientation on green cosmetic product purchasing behavior: comparison of different countries
Baltacı, Duygu Çinar; Durmaz, Yakup; Baltacı, Furkan
The growing concern for environmental issues has reached a critical level, demanding immediate attention. With the widespread integration of cosmetic products into daily routines, the escalating environmental impact cannot be ignored. Consumers are increasingly scrutinizing the environmental footprint of their purchases and the practices of manufacturing companies. To maintain their competitive edge, businesses must proactively understand and address the evolving needs and expectations of their consumers. This study aims to reveal the relationships between consumers’ environmental values, attitudes toward green products, and green cosmetics purchasing behaviors to guide decision-makers in the cosmetics industry. In addition, the study also evaluated the impact of consumers’ cultural backgrounds on their attitudes toward green products and their purchasing behaviors in the green cosmetics sector. We conducted a comprehensive online survey by collecting primary data from 883 respondents from 10 countries in Asia and Europe. Our analysis used partial least squares (PLS) with SMART PLS to comprehensively examine the interrelationships between variables. An ecocentric orientation positively influences attitudes and purchasing behavior toward green cosmetic products, while an anthropocentric orientation has a negative effect. Additionally, consumers’ attitudes mediate the impact of environmental attitudes on purchasing behavior and counteract the negative effect of anthropocentric attitudes. Cultural differences significantly impact consumers’ attitudes and purchasing behavior for green cosmetics. The study’s findings offer valuable insights for cosmetic companies dealing with growing demand for cosmetic products and environmental awareness. The empirical support for existing literature is significant, and the study’s structural model enriches the green cosmetics literature. It’s essential to consider both consumers and producers for sustainable green cosmetic production, ensuring profitability and encouragement for producers.

Şan, Murat; Nacar, Sinan; Kankal, Murat
The impacts of climate change are increasingly sensible, and Türkiye with its varied topography and diverse climate types is particularly exposed to these shifts. Understanding how precipitation patterns are evolving across its regions is therefore critical. While trend analysis is a widely used tool for this purpose, conventional approaches overlook periodicity, limiting their practical value for water resource management and irrigated agriculture. Therefore, this study aims to examine seasonal trends in long-term (1969–2020) monthly total precipitation in Türkiye, in which each calendar month is treated as a separate season in the sense of seasonal trend-analysis terminology, accounting for altitude, slope, geographical region, and Köppen climate classification. For this purpose, the seasonal Mann-Kendall (SMK) test and the innovative polygon trend Wilcoxon significance test (IPWST), a relatively new graphical method, were used, and the two approaches were comparatively evaluated. According to the study’s results, the rate of increase in coastal areas, specifically the Aegean and Black Seas, exceeds the rate of decrease. In contrast, the reverse is observed in inland and eastern regions. The IPTWST method indicates a more pronounced increasing trend in the Marmara and Mediterranean regions. Furthermore, although analogous trends are observed at lower slopes and altitudes, analyses indicate that these trends are more strongly related to altitude, with the rate of increase decreasing as altitude increases. The IPTWST identified significant or weak trend signals at a larger number of stations than the SMK, particularly in relation to altitude. Nationwide, the two methods revealed significant increases of 7% and decreases of 6%, respectively; this pattern was supported by statistical tests, reflecting the variability of regional climates and the influence of topographic factors on trend analysis.

Mediostoma izmiricum Snegovaya, Kurt and Yağmur, is a species of the family Nemastomatidae Simon, and is endemic to Türkiye. To date, there is no molecular data available for the 16S rRNA gene region for this species or its genus, which limits our knowledge of its phylogenetic position. The 16S rRNA gene region of this species was analysed for the first time, yielding a sequence length of 465 bp. Bayesian inference (BI) and maximum likelihood (ML) phylogenetic trees were subsequently constructed based on these data, revealing the phylogenetic position of both the species and its genus.
- MakaleAçık Erişim2026Scopus SJRQ2Topic Modeling of Occupational Accident Narratives in the Manufacturing Sector Using BERTopic: Sector-Specific Accident Pattern Analysis
Aktaş, Esra; Atmaca, Hatice Ediz
Despite technological developments and increasing awareness in the field of occupational health and safety, occupational accidents remain one of the fundamental problems that continue to have significant economic and social consequences. Particularly in the manufacturing sector, the diversity of production processes, differences in the machinery and equipment used, and the complexity of working environments cause occupational accidents to exhibit risk patterns that are both shared across sectors and specific to individual sectors. In this context, this study conducted a topic modeling analysis using the BERTopic algorithm on 1,600,000 occupational accident narratives to identify sector-specific risk patterns and error types associated with 24 different economic activities within the manufacturing sector. To improve topic modeling performance, a multilingual SentenceBERT-based embedding model and a Turkish-specific tr-MTEB embedding model were compared, and the analysis was carried out using the model that provided higher representational capacity and better topic separation performance for the occupational accident narratives. The findings show that, although the sectors differ in terms of production structure, types of machinery and equipment used, material characteristics, and working environments, occupational accidents largely cluster around similar risk mechanisms. As a result, it was determined that the BERTopic method makes the sectoral risk patterns embedded in occupational accident narratives more visible and provides an analytical basis for developing sector-specific prevention strategies in occupational safety practices.

- MakaleAçık Erişim2026Scopus SJRQ1Protecting the Privacy of Patients With Impaired Consciousness in Intensive Care: A Qualitative Study
Tuncer, Metin; Özalp, Cemal; Keskin, Azra
Background: Maintaining privacy in intensive care units (ICUs) is challenging because of high workload, invasive procedures, continuous monitoring and shared care environments. Patients with impaired consciousness may be particularly vulnerable because their ability to express privacy preferences, assert personal boundaries and advocate for themselves is limited. Aim: To explore intensive care nurses' experiences of protecting privacy when caring for patients with impaired consciousness. Study Design: A descriptive qualitative study was conducted with 20 intensive care nurses in Türkiye between March and April 2026. Data were collected through semi-structured online interviews and analysed using inductive thematic analysis. The study was reported in accordance with the Consolidated Criteria for Reporting Qualitative Research guidelines. Findings: Four themes were identified: the marginalisation of privacy under clinical priorities; structural and process-related constraints on privacy in intensive care; loss of subjectivity and the mechanisation of care in patients with impaired consciousness; and ethical and psychosocial implications of privacy violations. Conclusions: Privacy in intensive care is shaped not only by individual ethical awareness but also by workload, environmental conditions, care routines and communication practices. Patients with impaired consciousness have the same rights to privacy and dignity as other patients; however, their reduced ability to express preferences, assert personal boundaries and advocate for themselves may make privacy violations less visible and increase their dependence on nurses for protection. Relevance to Clinical Practice: Protecting the privacy of patients with impaired consciousness in ICUs requires structured care routines, standardised bedside communication, minimisation of unnecessary exposure during procedures and targeted ethical awareness training to support dignity in everyday practice.
- MakaleAçık Erişim2026Scopus SJRQ1The past scene of hospitality ethics: A citation analysis perspective
Polat, Eray; Köseoglu, Mehmet Ali
The literature on ethics research in hospitality has significantly expanded in recent years. The objective of this study is to present a comprehensive overview of ethical research in the field of hospitality literature. This will facilitate insight into future developments by examining the past. A two-step approach is employed, comprising citation analysis, a bibliometric analysis technique, and a systematic review. The former is used to identify themes, which are then discussed in the latter. The citation analysis revealed five main themes of the domain: environmental concerns, organisational citizenship behaviour, reputation management and ethical leadership. Environmental concerns were examined from two perspectives: the viewpoint of hotels and the environmental behaviours of tourists and consumers. Subsequently, a systematic review was conducted using the TCM framework (theory/context/methodology) with the objective of identifying the most prominent theories, contexts, and methodological issues associated with each theme. The issue has predominantly been discussed using quantitative analysis and social-based theories. Research has been mainly conducted in the US and the EU. Environmental ethics is likely to remain a significant area of concern in the future. This study offers a perspective that can aid researchers in developing future studies on ethics and help practitioners enhance the ethical climate of the industry.

Uysal, Turan; Kaya, Selim
This study investigates the gamma-ray and neutron shielding performance of advanced ceramic composites containing colemanite, pyrophyllite, and plastic clay as environmentally friendly alternatives to conventional lead-based shielding materials. Gamma-ray attenuation properties were evaluated over the energy range of 59.54–2000 keV using theoretical calculations from WinXCOM and Monte Carlo simulations performed with the EGS4 code. Excellent agreement between the two methods confirmed the reliability of the simulation results. The mass attenuation coefficient (μ/ρ) decreased with increasing photon energy due to the transition from photoelectric absorption to Compton scattering and pair production mechanisms. Correspondingly, the half-value layer (HVL) and mean free path (MFP) increased, while radiation protection efficiency (RPE) decreased with photon energy. The effective atomic number (Zeff) exhibited an energy-dependent decline, reflecting changes in dominant photon–matter interaction processes. Neutron shielding performance improved with increasing colemanite content owing to the presence of boron-rich phases, and Sample-5 exhibited the highest fast neutron removal cross-section (ΣR = 0.11062 cm−1). The same sample also showed the highest gamma-ray kerma coefficients, indicating enhanced energy absorption capability. Overall, the results demonstrate that colemanite-enriched ceramic composites provide effective combined gamma-ray and neutron shielding and represent promising, sustainable, and non-toxic alternatives for radiation protection applications.
