- MakaleAçık Erişim2026Scopus SJRQ1An Integrated MCDM Framework for Sensitivity of Weighting Methods and Ranking Aggregation: Evidence From Financial Performance Evaluation
Macit, Nazife Şahin
This study proposes an integrated framework for evaluating alternatives in Multi-Criteria Decision Making (MCDM) by addressing weight sensitivity and ranking integration. The aim is to examine the effects of different criteria-weighting methods on ranking results and to develop a more consistent decision-making structure by integrating the resulting rankings. Financial performance indicators of Derimod Konfeksiyon A.Ş., listed on Borsa Istanbul (BIST), were evaluated using the Entropy, WENSLO, and MPSI weighting methods, while the MACAD method was employed to rank the alternatives. The analysis was initially conducted for the 2018–2024 period; however, identical rankings obtained across all weighting methods limited the assessment of weight sensitivity. Therefore, the analysis period was extended to 2015–2024, resulting in ranking variations that enabled a more meaningful comparison of the weighting methods. In the final stage, the resulting rankings were integrated into a single consensus ranking using the CURLIA method. The findings indicate that the proposed framework reduces inconsistencies arising from the use of different weighting methods and produces more stable and reliable performance evaluations. Consequently, the study contributes to the MCDM literature by presenting an integrated methodological framework and demonstrating its applicability to financial performance evaluation.

Çam, Alper Veli; Soydaş, Şafak Sönmez; Özbek, Adem; Çam, Handan
Background: Financial exploitation constitutes a significant psychological vulnerability shaped by cognitive resources, emotional regulation, and financial decision-making behaviors. While financial literacy is widely recognized as a protective factor, limited empirical evidence disentangles the distinct psychological roles of financial knowledge, attitudes, and behaviors in reducing vulnerability to financial exploitation. Methods: This cross-sectional study analyzed survey data from 565 adults in Türkiye. Financial literacy was conceptualized as a multidimensional construct comprising financial knowledge, financial attitude, and financial behavior. Vulnerability to financial exploitation was assessed through three psychosocial indicators: self-confidence, financial anxiety, and financial satisfaction. Structural Equation Modeling (SEM) was employed to examine the relationships among cognitive, behavioral, and emotional components. Results: Financial knowledge was significantly associated with lower financial anxiety and higher financial satisfaction but showed no direct effect on self-confidence. Financial behavior emerged as the most robust protective factor, significantly enhancing self-confidence and financial satisfaction while substantially reducing financial anxiety. Financial attitude was positively related to financial satisfaction but did not significantly influence anxiety or self-confidence. Financial anxiety demonstrated a strong negative association with both self-confidence and financial satisfaction. Conclusions: Financial exploitation vulnerability is driven by interconnected psychological mechanisms rather than cognitive factors alone. The findings highlight the central role of behavior-based financial competencies and emotional regulation in strengthening financial resilience. Interventions aimed at preventing financial exploitation should prioritize behavioral skill development and psychological risk screening alongside traditional financial education approaches.

Salad, Aisha Mohamud; Akar, Zeynep
Biogenic synthesis using plant materials provides a sustainable alternative to classical nanoparticle fabrication, minimizing chemical hazards and decreasing energy input. In this study, silver nanoparticles (AgNPs) were prepared using an aqueous extract of Mercurialis annua and characterized. Physicochemical properties of the AgNPs were confirmed using ultraviolet–visible spectroscopy (UV–Vis), Fourier transform infrared (FTIR) analysis, X-ray diffraction (XRD), and transmission electron microscopy coupled with energy-dispersive X-ray (TEM–EDX), which collectively indicated crystalline, spherical silver nanoparticles stabilized by extract-derived functional groups. Subsequently, the biological activities of both the nanoparticles and the extract were comparatively evaluated using antioxidant tests, including cupric ion reducing antioxidant capacity (CUPRAC), ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH), total phenolic content (TPC), and total flavonoid content (TFC), as well as enzyme inhibition tests targeting α-glucosidase and carbonic anhydrase. Liquid chromatography-mass spectrometry profiling identified 31 phenolic constituents in the extract, with ferulic, caffeic, salicylic, and 4-hydroxybenzoic acids detected in high abundance. Overall, the biosynthesized AgNPs demonstrated higher antioxidant performance and stronger inhibitory effects on both enzymes compared with the crude extract. These results indicate that M. annua-based AgNPs hold considerable promise sustainable and effective bioactive agents for future biomedical and biotechnological applications.

Altay, Kadriye; Akdoğan, Arda; Erdoğan, Selma Lubabe; Koç, Gülşah Çalışkan
Olive pomace (OP), a by-product of olive oil production, is a rich source of various bioactive compounds. OP can be used as a value-added product for the development of functional food. The research aimed to produce functional crackers incorporating different levels of OP powder (ranging from 0% to 20%). Subsequent analysis involved evaluating the physicochemical and phytochemical compositions, antioxidant activity, mineral content, and sensory characteristics of all samples. In light of the findings, the samples containing OP powder are rich in phytochemicals (total phenolic and flavonoid contents), with higher antioxidant activities (total antioxidant content, DPPH radical scavenging activity, ABTS radical scavenging activity, and ferric reducing power), as well as a high amount of minerals compared to the control sample (P<0.05). Moreover, as the concentration of OP increased, there was a decline in the moisture content, water activity, and color values of the crackers. Conversely, the ash, fat, total flavonoid, total phenolic, and mineral contents, as well as antioxidant activity and hardness values, exhibited an increase. Sensory analyses revealed that the addition of 10% OP powder produced highly acceptable crackers compared to the higher concentration of OP (15 and 20%). Overall results indicated that functional crackers can be produced by the addition of powder and a maximum of 10% OP powder fortification is recommended for consumer acceptability.

Yadav, Subhash Kumar; Arya, Diksha; Sharma, Prayas; Zaman, Tolga
The Quest for the improved estimators of population mean is a continuous process to estimate it more efficiently and more closely to the true population mean of the study variable. There are various estimators of population mean in the literature, which estimate it efficiently, but still there is space for more efficient estimators. For improved estimation of population mean of primary variable, we suggest six different searls type ratio estimators utilizing the known auxiliary parameters. We derive the expressions for the biases and the mean squared errors of the introduced estimators for an approximation of degree one. The optimal values of the Searls characterizing constants, which minimize the mean squared errors of the introduced estimators, are obtained. The least value of the mean squared error of the proposed estimators for these optimal values of the characterizing scalars is also acquired. The efficiency of the proposed estimators is compared theoretically with the competing estimators of population mean through their mean squared errors. We derive the efficiency conditions of the proposed estimator for which it is more efficient than the estimators of population mean in competition. These efficiency conditions of the proposed estimators are verified through empirical data and the improvement over the competing estimators is calculated based on the minimum values of the mean squared errors. It is evident from the numerical study that the proposed estimator has the least mean squared error and the highest percentage relative efficiency in comparison to competing estimators. Thus, the proposed estimators are recommended for applications in different areas of applications.

İncele - MakaleYalnız künye2026Scopus SJRQ3Do special economic zones support regional development in transition economies? The case of Kazakhstan
Önder, Kübra; Şahin, Muhammet
This study examines the impact of Special Economic Zones (SEZs) in Kazakhstan between 2000 and 2023 on regional development, explicitly accounting for institutional and spatial heterogeneity. For causal identification, it employs a Forward Orthogonal Deviations-based GMMf (System GMMf) estimator to address endogeneity and reverse causality, complemented by an event-study framework to trace the dynamic evolution of policy effects. The results reveal strong path dependence in regional growth and show that the effectiveness of SEZ incentives is non-linear and systematically conditioned by the depth of regional production structures, proxied by the Value Added Index. Empirical evidence suggests that SEZ incentives stimulate growth in low value-added regions, while potentially distorting market signals and generating crowding-out effects in regions with high value-added production. Dynamic analyses indicate that the negative shock observed immediately after implementation reflects temporary adjustment costs and resource reallocation, with effects converging towards zero over time. Overall, the findings imply that SEZs are not automatic engines of growth but require careful calibration to local production structures to mitigate risks of policy saturation and adverse selection. The study provides an original contribution to the literature on the design and life-cycle management of next-generation industrial policies in transition economies.

Çelebi, Turan Meriç; Çelikağı, Yusuf; Kınay, Tuana; Kuyucu, Arda Cem; Kurnaz, Muammer; Şahin, Mehmet Kürşat
Eyelids play a crucial role in protecting the eyes of vertebrates; however, certain reptile species, such as Ophisops elegans, completely lack movable eyelids. In this study, we present the first video-documented evidence of a blink-like reflex in O. elegans, captured through endoscopic field observations and corroborated by laboratory video analysis. The observed movement consisted of a brief convex deformation of the ocular surface, lasting approximately 0.3 s and resembling a blink despite the presence of a fixed transparent brille. This behavior was observed once in the field and twice under controlled laboratory conditions. We propose that O. elegans may employ subtle contractions of the ocular musculature to mimic the protective function of blinking. These findings indicate a novel compensatory mechanism in eyelidless lizards and underscore the need for further research into ocular adaptations among reptiles.

Aim: This study was conducted to examine how nurses experience discriminatory behaviors in the workplace and how these experiences are reflected in their career development. Background: Although discrimination constitutes a significant challenge in nurses’ professional lives, qualitative research examining how these experiences influence their career development processes remains limited. Methods: This phenomenological study was conducted with nurses working in a public hospital in Turkey. Semi-structured individual interviews were conducted with 21 nurses during the study. Participants were selected from various clinical settings through purposive sampling. Data were analyzed using Colaizzi's seven-step content analysis method. Ethics committee approval was obtained for this study. The Consolidated Criteria for Reporting Qualitative Research checklist guided the study reporting. Results: Five main themes with seven subthemes emerged: (1) Discrimination Experiences (types of discrimination, sources of discrimination, emotions/feelings), (2) Reporting Behavior (decision and consequences of reporting, reasons for not reporting), (3) Impact of Discrimination on Career Development (supportive effect, hindering effect), (4) Coping Strategies, and (5) Suggestions for Preventing Discrimination. Discussion: These themes highlight that discrimination is a multidimensional phenomenon and that holistic approaches must be developed at emotional, structural, professional, and institutional levels to cope with it. Conclusion: For some nurses, discrimination acts as a transformative process that supports career development, while for others, it represents a significant barrier to professional advancement. Implications for Nursing/Nursing Policy: The findings highlight the need to strengthen reporting mechanisms, establish a supportive work culture, and implement inclusive institutional policies that promote career development.

Duran, Celal; Ozdes, Duygu; Ozdemir, Olcay; Onal, Yunus; Gundogdu, Ali
The tea industry generates substantial quantities of solid waste with limited high-value industrial applications. In this study, tea industry waste was converted into boric acid-activated carbon (BA–TAC) through a simple one-step chemical activation process and evaluated as an adsorbent for phenol removal from aqueous solutions. BA–TAC exhibited a mixed micro–mesoporous structure with a BET surface area of 592.59 m2 g−1. The adsorption performance was investigated as a function of solution pH, contact time, and initial phenol concentration. Adsorption kinetics were evaluated using pseudo-first order, pseudo-second order, Elovich, Avrami, and intraparticle diffusion models, whereas equilibrium data were analyzed using Langmuir, Freundlich, and Sips isotherms. Linear, pseudo-linear, and non-linear regression approaches were comparatively evaluated, demonstrating the limitations of conventional linearization and the superiority of direct non-linear regression. Moreover, the so-called linearized forms of multi-parameter models such as Sips are not truly linear because iterative parameter estimation remains necessary. The maximum experimental phenol adsorption capacity reached 101.80 mg g−1 despite the moderate BET surface area of BA–TAC. The experimentally determined natural pH and pHpzc values, together with the limited desorption efficiency, indicated that adsorption was governed predominantly by surface chemical interactions rather than electrostatic attraction alone. XPS analysis confirmed the incorporation of boron-containing surface functionalities, highlighting their contribution to phenol adsorption. Overall, this study demonstrates the successful valorization of tea industry waste into a functional boron-modified activated carbon while providing methodological guidance for reliable adsorption kinetics and equilibrium modeling, thereby supporting sustainable waste valorization.

Digital wallets have been provided by FinTech businesses thus reengineering the financial services but nonetheless there is a possibility of keyloggers, bogus personas and assaults of the server with conventional systems using PIN authentication. The current multi-factor authentication configuration usually leaves sensitive biometric information exposed as the logins are processed. To address these security issues, the paper proposes the MHESecAuth that employs Multi-Factor Homomorphic Encryption and Smart Contracts to authenticate. The permission to make transactions is secure since the system operates with PINs, OTPs and no one can view the biometrics. As per experimental research, the system can be accurate at 96.4 percent, false acceptance rate is 0.08 percent, false rejection rate is 0.6 percent and encryption consumes 160ms. The framework optimizes security, privacy and performance against both MFA, encryption-only and combined solutions and is therefore suitable in the development of quantum-secure digital wallets and still blockchain-based audit and transparency.

Recepoğlu, Mürşit; Cay Cakir, Sümeyra; Cakir, Mehmet Ali; Artan, Seyfettin; Hayaloğlu, Pınar; Keşap, Doğan
Environmental degradation has manifested in various forms, including air and water pollution. Therefore, the impacts of environmental policies should be evaluated across all dimensions of environmental degradation. The European Union has targeted to stop CO2 emissions by 2050. Accordingly, the literature has predominantly focused on the relationship between environmental taxation and CO₂ emissions. Even if the net-zero emissions target is achieved, this does not necessarily ensure the elimination of overall environmental degradation. This study investigates the impact of environmental taxation on environmental degradation in the European Union over the period 1995–2021 using the Driscoll-Kraay (1998) estimator. The study focuses on the impact of environmental tax on ecological footprint and its subcomponents. The findings show that the ecological footprint and its subcomponents, except for built-up land and forest product footprints, can be mitigated by current environmental tax policies. However, in order to achieve net-zero environmental degradation, the European Union must reduce pressures arising from built-up land and forest product footprints. In addition to the Driscoll-Kraay (1998) estimator, the Feasible Generalized Least Squares (FGLS) estimator is employed as a robustness check, and the results remain broadly consistent across both methods. Moreover, Dumitrescu and Hurlin (2012) causality test states that strong and bidirectional causal relationships between environmental tax and ecological footprint components. This overall result confirms the existence of a green dividend within the double dividend hypothesis. It is suggested that renewable energy plants should be constructed in areas where built-up land and forest products footprint are not affected. For example, floating solar panels do not use land and also protect water bodies from evaporation.

Şengün Inan, Figen; Canbolat, Özlem; Aslan, Kübra; Tuncer, Gülsüm Zekiye
Background Nurses play a key role in the care of patients with delirium; however, there is a lack of research exploring intensive care nurses' communication-related experiences in this context. Purpose This qualitative study aims to explore nurses' experiences related to communication in the prevention and management of delirium in intensive care settings. Methods This descriptive qualitative study was conducted with nurses working in the intensive care unit of a university hospital in Türkiye. Data were collected through semi-structured individual interviews. The sample consisted of 15 nurses. To ensure the analysis of the data, the content analysis method was used. Results Findings were categorized into five themes: (1) perceptions, (2) elements of effective communication, (3) obstacles to effective communication, (4) results of effective communication, and (5) results of ineffective communication. Conclusion The results revealed that nurses perceived communication in delirium management as an important therapeutic component of nursing care. In their view, effective communication supported patient care and family cooperation. Beyond individual efforts, organizational leaders may play a crucial role in improving delirium care by allocating adequate time and resources to structured educational programs that enhance communication competencies and delirium-specific knowledge.

Çakmak, Seher; Uzun, Sevda; Demi̇r Çam, Sevgi; Tamam, Yusuf
Background: The aim of this study is to evaluate the psychosocial dimension of Parkinson’s disease and the life experiences of patients with a phenomenological approach. Methods: In this phenomenological study, semi-structured in-depth interviews were conducted with 20 Parkinson’s patients who applied to the neurology outpatient clinic of a state hospital in a province in southern Turkey. Criterion sampling method, one of the purposive sampling methods, was used to reach the sample group. Interviews continued until data saturation was achieved. All interviews were recorded on a voice recorder after obtaining the necessary permissions from the patients and then transcribed. The data of the study were evaluated using thematic analysis. The study was conducted and reported according to the COREQ checklist. Results: Data analysis revealed three main themes (metaphors for Parkinson's disease, effects of Parkinson's disease, symptom management and psychosocial needs in Parkinson's disease) and eight sub-themes (metaphors for physical effects, metaphors for mental effects, metaphors for social effects, mental, physical, social, symptom management and psychosocial needs). Conclusions: As a result of this study, it was determined that Parkinson's disease negatively affects patients psychosocially and they have difficulty in coping. It is recommended to implement research and application centers for Parkinson's patients with a focus on psychosocial support and to carry out awareness and awareness-raising studies on Parkinson's disease. Studies on this subject are very limited and it is recommended that large-scale studies on psychosocial problems in individuals with Parkinson's disease be conducted in the future.

Türkkan, Tuğba; Hatipoğlu, Ertuğrul; Yücel, İbrahim; Kulakaç, Nurşen; Sipahi, Ferkan; Zeybek, Halil İbrahim
Violence against women represents a severe violation of human rights and has become a pervasive issue globally. This study aims to examine the risk factors associated with violence against women in a developing country context, specifically Turkey. This study adopted a cross-sectional research design. The study sample comprised 391 women living in a northeastern Turkish province, selected using a stratified sampling method. Participants’ ages ranged from 20 to 60 years, with a mean age of 40.83 years. The findings revealed a positive correlation between the age of both women and their spouses and the likelihood of experiencing physical and verbal violence. Factors such as the number of marriages, duration of marriage, number of children, and spousal infidelity emerged as significant risks for victimization. Additionally, an early age at first marriage, the presence of mental illness, and addiction problems were identified as critical risk factors for women’s victimization in violence. Education and employment were protective factors against violence, with higher educational levels and employment status for women and their spouses reducing the risk. Regression analyses further identified women’s education level, prior exposure to domestic violence, age at first marriage, and the addiction status of the spouse as significant predictors of violence against women. The findings provide valuable insights into the etiology of violence against women. In conclusion, the study has the potential to guide the development of more targeted and effective strategies to combat this pervasive public health and human rights issue.

Özparlak, Arif; Gül, Uğur; Karakaya, Dudu; Efe, Emine
Objective The aim of this study was to develop the Healthy Internet Use Scale for Adolescents (HIUS-A) and examine its psychometric properties in order to evaluate healthy internet use (HIU) among adolescents. Methods The study was conducted according to a methodological, correlational and cross-sectional design. Data was collected between September and December 2025 at three middle schools and three high schools in the province of Antalya, Türkiye. The study used a stratified sampling method, and it was completed with 516 adolescents. The scale's content validity was examined through expert evaluation, and its construct validity was tested through exploratory and confirmatory factor analyses. The reliability of the scale was assessed using Cronbach's alpha coefficient, split-half reliability, and item-total correlations. Results The analyses revealed that HIUS-A exhibited a two-factor structure explaining 49.1% of the total variance. These factors were named “self-control” and “conscious use”. Confirmatory factor analysis findings revealed that the model showed a good level of fit (χ2/sd = 1.450; RMSEA = 0.042; SRMR = 0.039; CFI = 0.981). The internal consistency coefficient was calculated as 0.864 for the total scale, 0.855 for the “self-control” subscale, and 0.711 for the “conscious use” subscale. Conclusion HIUS-A is a valid and reliable ten-item assessment tool for evaluating healthy internet use in adolescents. Implications for practice The scale may be used by nurses and other healthcare professionals to determine HIU levels in adolescents and to evaluate the effectiveness of intervention studies relating to HIU.

Objective: The no-reflow phenomenon in ST-segment elevation myocardial infarction (STEMI) is a significant clinical issue associated with poor cardiovascular outcomes. This study aimed to develop and compare multiple supervised machine learning algorithms, including the recently introduced Kolmogorov-Arnold Network (KAN), to predict the occurrence of the no-reflow phenomenon in patients with STEMI undergoing primary percutaneous coronary intervention (PCI). Method: This prospective, single-center study included 890 consecutive STEMI patients undergoing primary PCI. The Synthetic Minority Over-sampling Technique (SMOTE) was utilized to address class imbalance during training. Feature selection using analysis of variance (ANOVA) F-statistics and validation of feature independence (Variance Inflation Factor [VIF] < 5) identified ejection fraction (EF), baseline troponin level, stent length, B-type natriuretic peptide (BNP) level, and total ischemic time as the most influential predictors. Results: The KAN and Extreme Gradient Boosting (XGBoost) models achieved the highest predictive accuracy (area under the curve > 0.98, F1 > 0.95), outperforming traditional models such as logistic regression and decision tree classifiers (DeLong test, P < 0.001). Feature selection improved efficiency and reduced runtime by 20–40%, while Shapley Additive exPlanations-based (SHAP-based) explainability confirmed that the predictions were physiologically consistent: higher EF and lower BNP reduced the probability of no-reflow, whereas longer stent length and ischemic time increased it. The superior performance of KAN and XGBoost underscores the importance of modeling nonlinear relationships and multidimensional interactions among clinical, laboratory, and procedural variables. Conclusion: These findings suggest that KAN may serve as a reliable analytical framework for exploring complex cardiovascular outcomes. However, further multicenter and externally validated studies are needed to confirm its generalizability and potential role in clinical risk assessment.

Erol, Ismail; Oztel, Ahmet; Peker, Iskender; Ar, Ilker Murat; Benli, Tolga; Turan, İsmet
Charging the increasing number of electric vehicles (EVs) in use requires the deployment of EV charging station networks (EVCSN). However, there are various challenges to deploying EVCSN in a sustainable manner. Türkiye, a developing country, should also build a robust EVCSN to encourage future adoption of EVs as the country’s market for EVs has been rapidly growing. The literature review concludes that no previous study has systematically explored challenges to the sustainable deployment of EVCSN. The goal of this study is, therefore, twofold: first, it identifies those challenges through the lenses of commonly used theories. Second, it explores them using a multi-criteria decision-making (MCDM) framework that incorporates a rough-derived interval-valued neutrosophic set (R-IVN)-based ISM into MICMAC. By deriving interval neutrosophic information from single-valued expert inputs using rough number operators, the proposed approach more accurately captures epistemic uncertainty and variability in expert judgments compared to conventional interval-based models. The method is further validated through a novel Dice–Sørensen similarity index-based simulation approach. The findings of this study suggest that developing government policies and regulations and addressing the existence of vertically integrated companies are the critical challenges with higher driving powers. These findings provide key responsibilities for stakeholders, including urban municipalities, in developing guidelines for EVCSN deployment.

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.

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.
