Kamiloğlu, Aybike; Kutlu, Naciye; Elbir Abca, Tuğba; Yılmaz, Özlem
The concepts of sustainable and green technology have come to the forefront due to problems such as increasing environmental pollution, depletion of resources, and uncontrolled increases in industrialization. Green chemistry aims to reduce or completely eliminate pollution in the environment. In this study, both the ultrasonic method, which is a form of green technology, and deep eutectic solvents, which are among green solvents, were used, and a perspective on creating economic value from a waste product (celery root peel) is presented. In this context, phytochemical compounds (total flavonoid content and antioxidant activities) were obtained from celery root peels by ultrasonic-assisted extraction using 10 different choline chloride–based deep eutectic solvents, and the results were compared with methanol, an organic solvent. As a result, according to the total flavonoid content, the most effective deep eutectic solvent was choline chloride to sucrose, while according to the antioxidant activity value, choline chloride to lactic acid was found to be effective. For all of the analyzed bioactive compounds, higher or equal yields were obtained with all deep eutectic solvent extracts compared to methanol, and deep eutectic solvents could be alternatives to organic solvents (such as methanol) that may have toxic effects on humans or the environment.

Kızıl, Hamit Emre
Carvacrol (CRV) is a phenolic monoterpene abundant in culinary herbs such as oregano and thyme and is well known for its potent antioxidant, anti-inflammatory, and neuroprotective properties. This study investigated the ability of CRV to counteract neurotoxicity induced by cyclophosphamide (CP), a widely used antineoplastic agent. Male Wistar albino rats were divided into five groups and received CP and/or CRV treatments. Neurotoxicity and neuroprotection were evaluated through biochemical assays, real-time PCR, histopathological and immunohistochemical analyses, and behavioral testing (Morris Water Maze). CP administration led to significant increases in oxidative stress markers, disruption of antioxidant enzyme activities, upregulation of inflammatory mediators (NF-κB, TNF-α, iNOS), dysregulation of apoptotic regulators (increased Bax and Casp-3, decreased Bcl-2), alterations in autophagy markers (Beclin-1, LC3A, LC3B), and suppression of Notch1/Hes1 signaling. Histopathological analyses revealed neuronal degeneration, vascular hyperemia, and increased GFAP and 8-OHdG expression in brain tissue. CRV treatment, particularly at higher doses, effectively mitigated these biochemical, molecular, and histological alterations. Notably, CRV administration preserved spatial learning and memory function in CP-treated rats, as demonstrated by the Morris Water Maze test, indicating functional neuroprotection. These findings highlight the multifaceted neuroprotective mechanisms of CRV and suggest its potential as a food-derived bioactive compound for development into functional foods or dietary supplements to improve the quality of life for cancer patients undergoing chemotherapy.

In the present study, Silver sulfide (Ag2S)-based nanocrystals (NCs) were synthesized by employing a facile hot injection method. These NCs are utilized as counter electrodes on dye-sensitized solar cells (DSSCs), representing a smart approach that utilizes these NCs as catalysts instead of platinum (Pt) for the first time. The study provides a comparative analysis of the performance of Ag2S-based counter electrodes (CEs) in DSSCs technologies the traditionally compared Pt-based electrodes under identical conditions. The findings showed that the Ag2S-based DSSCs exhibited a power conversion efficiency (ƞ) that was approximately 5.2 % higher than that of the platinum-based DSSCs. Consequently, the results of this study demonstrate that Ag2S-based NCs possess the potential to function as novel counter electrode materials for low-cost, Pt-free solar cells. Moreover, the results of this study bear considerable implications for the development of cost-effective and sustainable solar energy solutions. The advent of Ag2S-based NCs signifies a significant milestone in the quest for sustainable and efficient energy solutions. This study also invites further exploration into other potential material combinations and synthesis methods that could enhance the properties and performance of DSSCs.

Ecem Bayram, Nesrin; Yenigün, Baran; Gerçek, Yusuf Can
In recent years, it has been important in terms of green technology and sustainability to promote the use of natural deep eutectic solvents (NADESs), especially those based on natural products, for the extraction of bioactive components with different functional properties from foods. Therefore, in this study, the effects of green extraction technology (ultrasonic-assisted extraction) and green solvents (NADESs) on the recovery of bioactive components from lavender (Lavandula angustifolia L.) were investigated and evaluated. In addition, the degree of greenness of the analytical method used during the study was determined using the modified green analytical procedure index (MoGAPI). In this context, the total phenolic content (TPC), total antioxidant capacity, and individual polyphenolic profiles of lavender extracts prepared with two different NADES were investigated by liquid chromatography-tandem mass spectrophotometer. Based on the results obtained, it was determined that NADES formed with choline chloride:formic acid (ChCl:FA) had a higher potential to extract bioactive components from lavender than NADES formed with ChCl:ethylene glycol (ChCl:EG). The TPC, antioxidant capacity, and total individual polyphenolic compound content of lavender extracted with these NADES were determined as 9.76 mg gallic acid equivalent/g, 20.83–104.39 mg Trolox equivalent/g, and 200.835 mg/kg, respectively. However, the degree of greenness determined by the MoGAPI tool of the analytical method used in this study was 78% and classified as ‘excellent green’. As a result, it can be concluded that NADES formed with ChCl:FA can be an alternative to conventional solvents for the extraction of bioactive components from lavender, as it provides a remarkable recovery of bioactive substances.

Adiyaman, Gökhan; Turan, Muhittin
The bending and buckling analysis of porous two-directional (2D) functionally graded (FG) beams was conducted using a higher-order shear deformation theory. The introduction of exponential functions to depict changes in material properties is a novel approach in the static analysis of 2D FG beams. Three distinct porosity distribution functions were taken into account. The governing equations were formulated through the application of Lagrange’s principle. During the numerical analysis, a finite element comprising two nodes and eight degrees of freedom was utilized. This choice facilitated accurate and efficient solutions, even for shorter beams, without the need for a shear correction factor. Notably, the obtained shear stresses aligned with actual values, registering as zero at both the top and bottom of the beam. The obtained results of the study were validated against findings reported in the literature. A parametric study was carried out to investigate the effects of porosity, porosity distributions, gradation parameters, slenderness, and boundary conditions on the non-dimensional deflections, stresses, critical buckling loads, and buckling mode shapes. It was found that both porosity and the distribution of porosity have noticeable effects on the static analysis of the beams.

Yücel, Tuğçenur; Kamiloğlu, Aybike; Kutlu, Naciye
In this study, the ultrasonic-assisted method was applied to extract phenolic, flavonoid, and antioxidant compounds from germinated mung beans. In addition, deep eutectic solvents (DESs) were chosen as solvents to support the green concept and to increase their applicability. Choline chloride is a quaternary ammonium salt and was used as the hydrogen bond acceptor (HBA), and compounds from the alcohol, organic acid, sugar, and amide groups were combined as hydrogen bond donors (HBD) to obtain 8 different DESs. Higher yields were obtained with ultrasonic-assisted DESs compared to the traditional method (maceration) when total phenolic compound and antioxidant activities were evaluated. While the most effective solvent for total phenolic compound yield was choline chloride:fructose, the highest antioxidant activity values were obtained with solvents using organic acids as HBD. Moreover, Blue Applicability Grade Index (BAGI) was used to assess the greenness of the applied ultrasonic-assisted spectrophotometric extraction and DESs. As a result, using green technology and green solvents was influential in the extraction of bioactive compounds, and their applicability was especially effective for mung beans.

Özbilen, Uğur; Banaz, Emrullah; Şahin, Tuğrul Gökmen
Introduction: This study investigates the mediating role of psychological well-being in the relationship between digital reading disposition and artificial intelligence (AI) anxiety among Turkish teachers. Addressing the growing concern of technology-related anxiety in education, the research explores how digital literacy and psychological resilience interact within a single structural model. Methods: A correlational research design was employed with data collected from 324 teachers. Participants completed the Digital Reading Disposition Scale, the Psychological Well-Being Scale, and the Artificial Intelligence Anxiety Scale. Bootstrapped structural equation modeling (SEM) was used to test the measurement model and the hypothesized mediation effect. Prior to SEM analysis, confirmatory factor analysis (CFA) was conducted to establish construct validity of the scales. Results: Findings revealed that digital reading disposition was positively associated with psychological well-being and negatively linked with AI anxiety. Psychological well-being was also negatively related to AI anxiety. Moreover, psychological well-being partially mediated the relationship between digital reading disposition and AI anxiety. Discussion: The results suggest that teachers with stronger digital reading dispositions experience higher psychological well-being, which in turn buffers against AI-related anxiety. These findings contribute novel theoretical insights to educational literature by integrating digital reading, psychological well-being, and AI anxiety into a single model. Practically, the study underscores the importance of fostering digital literacy and psychological resilience to mitigate technology-related anxiety in educational settings.

Sarac, Mehmet Fahri; Mert, Merve; Solakyildirim, Tuba; Teber, Ahmet
The photosensing properties of TiO2/ZnO nanowires (NWs) were investigated by sequential deposition using thermal oxidation and sol–gel. It was found that TiO2/ZnO NWs with 5 mM concentration exhibit a higher aspect ratio compared to the 10 mM and 25 mM TiO2/ZnO NWs. The surface-to-volume ratio directly influences the photoluminescence (PL) intensity and electrical properties of the ZnO NWs. XPS confirmed the presence of TiO2 on the surface, while EDS detected titanium, with its concentration increasing as the TiO2 concentration rises. The photosensing performance of ZnO has been significantly improved by modifying it with TiO2. However, determining the optimum concentration is a critical factor in performance improvement. The findings show that high TiO2 concentrations improve surface properties, but excessive coating may limit carrier mobility. Photosensitivity has been increased at lower TiO2 concentration due to a higher surface-to-volume ratio (SVR) and, as a result, higher surface photoactivity. The 25 mM TiO2/ZnO NW array stands out in optimal detectability and photoresponsivity due to the reduced resistance caused by the increased Ti concentration on the surface. The 25 mM TiO2/ZnO NWs achieved the highest photoresponsivity (717 mA/W) and specific detectivity (1.48 × 101° Jones), while the 5 mM TiO2/ZnO NWs exhibited exceptional photosensitivity (320.11%), making them ideal for UV detection. The samples at varying concentrations show promise in photosensitivity, detectability, and photoresponsivity, making them suitable for environmental sensors, UV detectors, and other optoelectronic applications.

Glucansucrases (GS) are functional enzymes for the production of distinct glucan and gluco-oligosaccharide structures with potential bioactive characteristics. In this study, an active glucansucrase (GS40) was identified within the genome of Leuconostoc mesenteroides YTU 40 that was further cloned, heterologously expressed and biochemically characterised. GS40 was capable of production of a branched dextran with ~ 20% (1→3)-α-D-Glc residues detected by1H and13C NMR analysis. Acceptor reactions of GS40 with maltose and cellobiose were performed and distinct maltose/cellobiose derivative acetylated gluco-oligosaccharides were produced detected by TLC, NMR and LC-MS analysis. The bioactive characteristics of branched dextran and gluco-oligosaccharides were tested by determination of their immune-modulatory roles in terms of triggering IL-12, IL-10, IL-4 and TNF-α cytokine levels. These findings can be important to unveil the role of glucansucrases for the production of gluco-oligosaccharides that can be used as functional ingredients for food and other industries.

This study presents a structural analysis of NiO and the fabrication of Al/NiO/p-Si isotype heterojunction photodiode (PD) as well as an investigation of the photo-response and photovoltaic (PV) properties of the PD in the various illumination intensities. The series resistance (RS) value of the Al/NiO/p-Si was calculated to be 0.11 kΩ using Ohm’s Law at 2 V. This result corroborates the assertion that RS is the pivotal parameter for attaining optimal performance in a PD. The NiO has made a notable improvement to the electrical parameters such as ideality factor, barrier height, and series resistance. The spectral responsivity R value of the PD was calculated as 1.59 A W−1 at −2 V. The Al/NiO/p-Si exhibited a short-circuit current density (JSC) of 60.38 mA·cm−2, an open-circuit voltage (VOC) of 149.0 mV, a fill factor (FF) of 27.67%, and a power conversion efficiency (PCE) of 2.49%. In view of the experimental results, it can be concluded that NiO represents a promising material for the optimization of heterojunction photodiode applications.

Bayraktar, Bülent; Battal, Fetullah
Background: Emotional intelligence is a person’s ability, capacity and ability to understand, use, understand, manage, anticipate, manage and direct the emotions of oneself or others. Students with high levels of emotional intelligence express themselves better, are more resistant to stress in their lives, and are individuals who can direct their emotions. Leaders with strong emotional intelligence will create synergy for all employees. Therefore, emotional intelligence and stress management skills are important issues in the field of leadership and organizational behavior. At the same time, emotional intelligence and stress management skills interact with hormones. This study aims to examine the emotional intelligence levels and hormone (apelin, cortisol) and cerebral (Brain-derived neurotrophic factor (BDNF)) response of 4th-year students of the faculty of health sciences at the university, who are potential managers of the future in terms of some variables. Methods: The research was conducted using the cross-sectional data method with 167 university students aged 18–24 who were reported to be clinically healthy in Türkiye. Apelin, cortisol hormone and BDNF levels in the participants’ saliva samples were analyzed using the ELISA technique. The relationship between emotional intelligence level and total scores from the stress coping scale and salivary apelin, cortisol and BDNF levels were evaluated. Results: In the study, it was determined that the average level of apelin hormone in saliva was “2.36 ± 0.076)’’ ng/mL in girls and “2.57 ± 0.071’’ ng/mL in boys. In girls, the BDNF level was “3.19 ± 0.97’’ and the cortisol level was “2.04 ± 0.72’’. BDNF level in boys is “3.41 ± 0.94’’and cortisol level is “1.92 ± 0.59’’. There is a significant difference between the participants’ allowances (income levels) and the average levels of salivary apelin hormone, BDNF and emotional intelligence scale (p < 0.01). A positive, strong and statistically significant relationship was found between the participants’ emotional intelligence level and stress management skills and apelin and BDNF levels, and a negative, strong and statistically significant relationship was found between salivary cortisol levels (p˂0.01). Conclusions: High emotional intelligence and stress management skills are an important element of strategic importance for a successful management and professional success process in individuals who will work in fields that need people such as health, marketing, law, consultancy, medicine, teaching and the service sector. Our study determined that as university students’ emotional intelligence levels strengthened, the participants’ stress management skills, salivary apelin, and BDNF levels increased, and cortisol hormone levels decreased. As a result, monitoring and examining apelin, BDNF, cortisol hormones can be useful parameters in evaluating the interaction between individuals’ emotional intelligence level and stress management skills and hormone response.

Background: Participation in physical activity is considered an important factor not only for individuals’ physical health but also for their psychological well-being. Developing physical activity habits, especially among university-aged individuals, plays a critical role in long-term health outcomes. In this context, the impact of physical activity enjoyment on individuals’ mental well-being has become a topic of interest. However, the moderating role of individual differences, particularly gender, in this relationship has not yet been sufficiently clarified. The purpose of this study was to examine the relationship between physical activity enjoyment and mental well-being among university students and to reveal the moderating effect of gender on this relationship. Method: The research was conducted using a relational screening model. The study group consisted of 392 university students (261 male and 131 female; mean age = 22.95 ± 2.58) from Sakarya University of Applied Sciences who participated in campus recreation activities. Data were collected via a face-to-face survey using the Physical Activity Enjoyment Scale and the Mental Well-being Scale. Descriptive statistics, Pearson correlation analysis, and regression-based moderation analysis using PROCESS Macro Model 1 were used in the statistical analysis. Results: The level of enjoyment of physical activity was found to have a significant positive effect on mental well-being (r = 0.427, p = 0.001; F = 50.388, p < 0.001; R2 = 0.280). Moderation analysis further showed that gender significantly moderated this relationship (ΔR2 = 0.049; p < 0.001). The effect of enjoyment on mental well-being was significant for both males (β = 0.2693; S.E. = 0.0348; p < 0.001; 95% CI [0.2010, 0.3377]) and females (β = 0.7913; S.E. = 0.0949; p < 0.001; 95% CI [0.6047, 0.9780]), with the effect being stronger among females. Conclusion: The findings show that considering gender-sensitive approaches in physical activity programs to be implemented on university campuses has a potential impact on improving the psychological well-being of students.

This study aims to evaluate the effectiveness of social policies implemented in the aftermath of the February 6, 2023, Kahramanmaraş earthquakes. The research employed the Intuitionistic Fuzzy SIWEC technique, a multi-criteria decision making method. Eight experts with substantial field experience evaluated seven main criteria and forty-four sub-criteria. The findings indicate that social policies—particularly in the "food and basic needs" category (covering clean drinking water, hygiene products, the food supply chain, food safety, and the provision of special nutritional needs) and, more broadly, policies within the "health and education services" category—have been implemented successfully. In contrast, under the "employment and social security" category, efforts to combat informality, provide vocational training, grant tax exemptions, and support SMEs were deemed inadequate. Similarly, within the "basic infrastructure and public services" category, notable deficiencies were identified in urban planning and construction, in ensuring transparency and fairness in public social policies, and in restoring telecommunication and internet infrastructure. In addition policies targeting vulnerable groups and psychosocial support services were found to be relatively neglected.

Ari-Arat, Ceren; Cetinkaya, Elif; Oz, Koray
Objectives: Understanding the factors that influence parental acceptance during the preschool period when many children with developmental disabilities are diagnosed is crucial. Mindfulness in parenting is the intentional, nonjudgmental attention a person gives to their child and their parenting actions and is associated with processes of acceptance. This research examines the relationship between parental acceptance and mindfulness in parenting among parents of preschool children with developmental disabilities. Methods: The investigation included 120 parents of preschool-aged children (3–6 years) with developmental disabilities in Turkey. Results: The findings reveal that parental acceptance of children with developmental disabilities varies according to the father’s education level and the child’s age. A significant correlation was found between mindfulness in parenting and parental acceptance. Notably, mindfulness in parenting accounted for approximately 19.2% of the variance in parental acceptance of children with developmental disabilities (R2 = 0.192). Conclusions: The results underscore the importance of interventions aimed at enhancing mindfulness in parenting, particularly in supporting the acceptance processes during the preschool years. This is especially critical for younger children and for fathers with lower educational levels. The study also highlights the need for further research to deepen our understanding of the acceptance process.

Ozulku, Gorkem; Harris, Hannah C.; Savva, George M.; Ahn-Jarvis, Jennifer H.; İspirli, Hümeyra; Dertli, Enes; Warren, Frederick J.
Glucooligosaccharides (GLOS) produced by glucansucrases via acceptor reactions are oligosaccharides that transit upper intestinal tract and evade digestion and may be considered to be a prebiotic. The prebiotic function of GLOS can be dictated by the type of acceptor sugar used during its production. Therefore, the prebiotic effect on the gut microbiome and short chain fatty acids (SCFAs) production can be used to inform the selection of acceptor sugars. In this study, alternansucrase-based GLOS derived from different acceptor sugars (melibiose, cellobiose and lactose) and inulin (positive control) were investigated using in vitro colon model fermentation to examine their prebiotic effect and SCFAs production. Microbiome composition was determined using shotgun metagenomics. SCFAs and lactate formation was determined using 1H NMR spectroscopy. Fusicatenibacter saccharivorans and Bacteroides uniformis appeared to increase in abundance after 24 h following fermentation of all three GLOS. The highest abundance for Bifidobacterium longum was seen after supplementation with lactose derived GLOS. Fermentation of GLOS appeared to produce around twice as much acetate than fermentation with inulin, while similar amounts of other SCFAs and lactate were produced. Melibiose derived GLOS supplementation in healthy 3 donors increased F. saccharivorans while inulin supplementation promoted Lactobacillales in order level. This study suggests that there may be beneficial effects of GLOS's on gut microbiome composition and metabolite composition, relative to the effects seen for inulin.

Uçurum, Metin; Özdemir, Akın; Teke, Çağatay
Fly ash (FA) is the fine-grained waste product obtained by burning coal after being ground to specific sizes in thermal power plants, carried with flue gases, and kept in cyclones or electro-filters. Like every industrial waste, the possibilities of utilizing FA have been investigated, and it can be utilized as an additive in cement and concrete. Despite this, industrial waste, which increases daily in the world, brings many problems, especially environmental problems. For this reason, alternative usage areas of the waste in question are constantly being investigated. In this paper, FA containing approximately 50 % CaO from Afşin-Elbistan, Turkiye was processed with stearic acid in a planetary mill to be used as a filling material in industrial products, and it has a grain size of 68.10 μm on a d50 basis, a specific surface area (SSA) of 176.40 m2/g and a contact angle of 13.89. An optimization and characterization study was conducted to make the hydrophilic surface structure hydrophobic by mechanochemical surface modification. Also, surface modification parameters, such as operational speed (rpm), ball filling ratio (%), FA filling ratio (%), pulp density, stearic acid dosage (% of FA), and modification time (min.) were optimized with the D-optimal experimental design. Based on the optimum surface modification parameters, a coated fly ash (CFA) product was obtained with an active ratio of 99.70 %, a contact angle of 95.06o, a medium size (d50) size of 10.60 μm, and an SSA of 926.90 m2/g.

Akçay, Latif; Yalçın, Berna Örs
Lattice-based cryptography (LBC) algorithms are considered suitable candidates for post-quantum cryptography (PQC), as they dominate the standardization process put forward by the National Institute of Standards and Technology (NIST). Indeed, three of the four key encapsulation mechanism (KEM) algorithms in the third round of the process are based on computationally hard lattice problems. On the other hand, there is an urgent need for processor designs that can run PQC algorithms efficiently, especially for embedded systems. This study presents an application-specific instruction set processor (ASIP) design for the Kyber, Saber, and NewHope algorithms based on transport triggered architecture (TTA). Custom hardware accelerators are added to the baseline processor architecture for computation-intensive steps without applying any software optimization to the reference code. We compared FPGA and ASIC implementations of our design with the prominent RISC-V cores and instruction set extension studies in the literature. According to the results, the proposed design offers greater efficiency, better performance, and lower resource utilization than its competitors in most cases.
