Realistic Assessment of Electric Vehicle Policies in Africa: a Case Study of Ghana
(Elsevier Ltd, 2025) Ayetor, G.K.; Ativor, A.; Kesse, M.A.; Tawiah, P.O.; Diouf, B.; Opare, S.; Andoh, P.Y.
This research aims to provide a realistic assessment of Ghana's electric vehicle (EV) policy regarding energy requirements, capability to achieve its intended goals, implications to the national grid, and what is required to achieve it. The research uses the historical population census, vehicle registration, the net-zero target of the policy, and the Verhulst pearl curve equation to forecast the EV penetration and energy requirements. The mixed methodologies employed were unique such that it exposed mismatches between EV targets, grid readiness, and renewable energy timelines in a way that cannot be found in other studies. Fuel savings and greenhouse gas emissions were modeled based on the EV policy, penetration targets, and the International Energy Agency fuel economy dataset. The results indicate that the current incentives, and measures in place are inadequate to achieve the policy's objectives. The policy will lead to a 90 % reduction in transportation emissions in 2060, not net-zero emissions, unless higher renewable energy integration is pursued. To meet the policy targets, the capacity of public charging stations must expand by a minimum of 2 GW per year through 2060. Meeting the EV policy goals would increase total electricity demand to 415,390 GWh by 2060, significantly exceeding the BAU projection of 115,170 GWh. However, in the worst-case scenario, a 1 % yearly increase in EV penetration will require 223,249 GWh by 2060. Sensitivity analysis is recommended for future studies. © 2025 World Conference on Transport Research Society

Key innovations discussed include the use of phase change materials (PCMs) in TES, advanced direct absorption solar collectors (DASCs) with nanofluids, and composite-enhanced photovoltaic back sheets. We also explore the incorporation of eco-friendly materials, such as natural fibers, and the exciting potential of 2D materials like graphene and MoS2 in improving solar technology performance. The review stresses the importance of ongoing research to address challenges in material optimization and system integration, aiming to create scalable and reliable solar technologies. Ultimately, composite materials play a crucial role in the shift toward cleaner energy, helping make solar energy a more competitive, efficient, and sustainable solution to meet global energy needs. © 2025 International Solar Energy Society
Laboratory Investigation of Strength Evolution in Organic Soils Improved by Deep Mixing Method
(Elsevier Ltd, 2025) Zoriyeh Aligholi, H.; Bozbey, I.
This study investigates the effectiveness of deep soil mixing (DSM) in enhancing the strength and modulus of organic soils. The research evaluates how varying cement types, binder dosages, water-to-cement (w/c) ratios, and curing durations affect the mechanical properties of two different organic soils that were used; natural soil from the Golden Horn region of Istanbul with 12.4% organic content, and an artificial soil created from a 50/50 mixture of Kaolin clay and Leonardite, which has an acidic pH due to high organic content. The specimens were cured for four durations, ranging from seven days to one year. The testing program included mechanical testing; Unconfined Compression Tests (UCS), Ultrasonic Pulse Velocity (UPV) measurements, and chemical analyses; X-Ray Fluorescence (XRF) and Thermogravimetric analyses (TGA). The UCS tests indicated that higher binder dosages and extended curing durations significantly improved the strength. Higher w/c ratios resulted in decreased strength. Long curing durations resulted in strength values which were four times the 28-day strength values. This amplified effect of strength gain in longer durations was evaluated through “Curing time effect index, (fc)”. The results were presented in terms of cement dosage effect, effect of cement type, effect of total water/cement ratio (wt/c), standard deviation values, E50 values and curing time effect index (fc) values respectively. Results of UPV tests were used to develop correlations between strength and ultrasonic pulse velocities. Quantitative evaluations were made using the results of XRF and TGA analyses and strength. Significant amount of data was produced both in terms of mechanical of chemical analyses. © 2025 Elsevier Ltd
Review of Solar Pond Performance With PCM and NePCM
(Elsevier Ltd, 2025) Dhaidan, N.S.; Rashid, F.L.; Alkhekany, Z.A.K.; Kadhim, S.A.; Hammoodi, K.A.; Al-Obaidi, M.A.; Agyekum, E.B.
The Salt gradient solar pond (SGSP), or only solar pond (SP), is a system that utilizes a renewable solar energy source to store thermal energy in a brine. The use of phase change materials (PCMs) and nano-enhanced PCMs (NePCMs) to improve SGSPs performance has received limited attention in previous review articles. The current review organizes the available research into two primary groups to address this gap: SGSPs with PCMs and SGSPs with NePCMs. It also aims to uncover the challenges and areas where further investigation is needed and suggest future research paths to improve the efficiency and effectiveness of solar thermal energy technologies. The classical PCMs, especially paraffin wax, have high latent heat but low thermal conductivity, which has drawbacks to their effectiveness. The NePCM involves using nanoparticles like copper oxide (CuO) and aluminum oxide (Al2O3) to augment the heat transmission and thermal conductivity of PCMs substantially. The outcomes of different studies revealed that integration of SP with PCM enhances the SP's thermal and salinity stability, improves the average exergy and thermal efficiencies, decreases the heat loss from the SP, extends the operation duration, and results in more uniformity and less fluctuation in temperature compared to the SP without the PCM system. Using a PCM of a high melting temperature enhances SP stability and smoother SP peak temperatures. Meanwhile, lower melting PCM results in a more stable temperature during heat extraction. In addition, dispersion nanostructures with the PCM augment the thermal features, extend the operation period of the SP, and increase the stored energy within the SP and the thermal efficiency (up to 87.58 %). In addition, adding nanoparticles increased the average maximum temperature by 3.5 %–37.7 % depending on the nanoparticles' loading and type, PCM kind, and other geometrical parameters and weather conditions. In addition, attention should be paid to balancing the thermal enhancement effect and the adverse effect of increasing nanoparticles' viscosity and agglomeration possibility, especially at a relatively large concentration. Moreover, the affecting controlled parameters, the challenges faced by utilizing PCM and NePCM in SP applications, and suggestions for future studies are also discussed. © 2025 Elsevier Ltd
The Atomic and Thermal Performance of CuO Nanoparticles/Paraffin as Phase Change Materials in a Circular Tube: Molecular Dynamics Simulation Approach
(Elsevier B.V., 2025) Al-Timimy, S.Q.; Hassan, W.H.; Singh, N.S.S.; Naser, G.F.; Salahshour, S.; Sajadi, S.M.; Hekmatifar, M.
Background: Using molecular dynamics simulation, this study investigates the effect of CuO nanoparticle addition on the thermodynamic and atomic properties of an octadecane that was being utilized as a phase change material within a circular tube. Methods: The results indicate that the density (D) was greatest in the vicinity of the tube walls. At its peak, D was 0.0300 atoms per square centimeter. This behavior is due to the increased attractive force that is between the structure's boundaries and its particles. Particle velocity (V) values reached their utmost attainable values in the intermediate regions of the tube, where movement was greatest. At its peak, V was 0.0078 Å/fs. The tube exhibits a maximum temperature (Max T) value of 754.43 K at its midpoint. Significant Findings: Due to the increased particle motion in the intermediate regions, the investigated structure experienced a greater number of collisions in those areas. After 10 ns, the sample's heat flux, thermal conductivity, and thermal stability converged to values of 3.94 W/m2, 1.38 W/mK, and 1821 K, respectively. The structure showed charging and discharging times of 6.41 and 7.15 ns, respectively. © 2025 Elsevier B.V.
Optimising Phase Change Materials for Ventilated Building Components in Sustainable Building Design: a Comprehensive Review
(Elsevier Ltd, 2025) Rashid, F.L.; Al-Obaidi, M.A.; Hatem, W.A.; Al Maimuri, N.M.L.; Ameen, A.; Ahmad, S.; Hammoodi, K.A.
The rise in energy-efficient, sustainable building operations necessitates the development of advanced innovations that reduce heating and cooling demands while maintaining comfortable indoor thermal conditions. Phase change materials (PCMs) demonstrate significant potential as a stabilization mechanism through latent heat storage for managing residential indoor temperatures; however, their integration into systems requires further optimisation. This review examines PCM-assisted ventilation technologies—specifically ventilated façades, roofs, and windows—highlighting their energy performance, which ranges from 7.7 % to 32.8 %, and their capacity to reduce peak temperatures by 2.5 °C to 7.02 °C. These improvements are influenced by PCM thickness of 15–35 mm and melting temperatures of 15–37 °C. The combination of PCM-enhanced hybrid systems with natural or mechanical ventilation has shown greater operational effectiveness, particularly in hot climates and when integrated with adaptive control systems to achieve optimal performance. Despite their benefits, widespread adoption of PCM technologies is hindered by high material costs, hysteresis effects, and limited discharge cycle efficiency. Nevertheless, PCM-enhanced ventilation systems have proven capable of supporting sustainable, low-energy buildings. Continued research is needed to develop cost-effective design strategies, automated control mechanisms, and climate-responsive optimisations to fully realize their potential. © 2025 The Author(s)
Adaptation of Ventilation Strategies From Acute RDS To Severe BPD a National Multicenter Survey of Practices in Extremely Preterm Infants
(Lippincott Williams and Wilkins, 2025) Akyıldız, C.; Tüzün, F.; Duman, N.; Akcan, A.B.; Ünkar, Z.A.; Aygün, C.; Özkan, H.
Advances in diagnostic and therapeutic methods have led to a paradigm shift in the management of bronchopulmonary dysplasia (BPD). The lack of evidence-based data in this area has led to variations in clinical practice. The aim of this study was to identify these differences and compare them with recommendations based on pathophysiology. The study was designed as an observational online survey of neonatologists from level 3 to 4 neonatal intensive care units caring for premature infants at increased risk of BPD and born before 28 weeks’ gestation. Respondents were invited to participate in the study through the portal of the Turkish Neonatal Society. Participants were surveyed online about preferred ventilation modes, settings and clinical management of these patients through each respiratory distress syndrome, evolving BPD and severe BPD phases. A total of 39 centers involved in the study. Pressure-control assist-control volume-guaranteed was the most commonly preferred ventilation mode in respiratory distress syndrome and evolving BPD, while high frequency oscillatory ventilation was most commonly used in severe BPD. The use of synchronized intermittent mandatory ventilation volume-guaranteed pressure support ventilation increased with disease progression. Ventilation settings were found to be changed according to pathophysiological recommendations, but not to the extent recommended. The study shows that early ventilation strategies are predominantly maintained in the later phases of BPD, although there are notable differences between centers. Copyright © 2025 the Author(s).

Fabrication and Characterization of Biological Biosensors in Sports Injury Treatment: High Sensitivity of Silver Oxide Using Artificial Neural Network Modeling
(Elsevier Ltd, 2025) Wu, Y.; Moghadas, B.K.; Gu, D.; Salahshour, S.; Hashemi, M.
This study focuses on the potential of biosensor technology to revolutionize sports injury management. Conventional methods for sports injury management, such as physical examinations and imaging techniques, often lack the sensitivity and real-time monitoring capabilities required to track the healing process effectively. These methods are also invasive, relying on blood sampling, which can be uncomfortable for athletes. In contrast, the proposed wearable biosensor offers a non-invasive, painless alternative by measuring biomarkers like myoglobin and creatine kinase in sweat. This study introduces a novel graphene field-effect transistor biosensor integrated into a wristband, combined with an artificial neural network (ANN) model to predict material properties and optimize biomarker detection. The results show the potential of this technology to revolutionize sports injury management by providing real-time, accurate, and non-invasive monitoring of injury progression and recovery. The results indicate that changes in compressive strength and porosity have an impact on dissolution rate, pore size growth, and chemical stability. Lower compressive strength leads to an increase in dissolution rate, while higher compressive strength promotes pore size growth and chemical stability. The accuracy of the ANN model's predictions was evaluated using linear regression and demonstrated acceptable error levels compared to experimental testing. Among the nanocomposite hydrogel scaffolds containing silver oxide nanoparticles, a specific sample showed noteworthy characteristics, including a compressive strength of 2.4 Mega Pascal, 55 % porosity, 22 % dissolution rate, 27 % pore size growth, and 65 % chemical stability. © 2025 Elsevier Ltd
Environmental Reflections of Traditional and Improved Recipes: Assessing Greenhouse Gas and Water Footprints
(Elsevier B.V., 2025) Biliroğlu, C.; Demirel, B.; Kılınç, G.E.; Açar, Y.; Şensoy, F.
The concept of sustainability is expressed as to increase people's quality of life and reducing resource use and environmental impacts. The aim of this study was to determine the values of greenhouse gas emissions and water footprints of recipes with improved nutritional content specific to various Turkish cuisines. Thirty traditional recipes were improved in terms of nutritional content, and thirty improved new recipes were created. In this context, the carbon and water footprints of traditional and improved recipes were calculated, and the relationship between nutrients and greenhouse gas emissions and water footprints was analyzed. Compared to traditional recipes, improved recipes for meat dishes, pastries, herb dishes, vegetable dishes, and seafood recipes were found to have lower greenhouse gas emission values (p < 0.05), while the water footprint values of meat dishes, herb dishes, vegetable dishes and seafood recipes were found to be lower (p < 0.05). In traditional recipes, as the amount of energy, protein and fat increased, greenhouse gas values increased (p = 0.030 for energy; p = 0.001 for protein; p=<0.001 for fat), while in improved recipes, as the amount of protein and fat increased, greenhouse gas values increased (p = 0.001; p = 0.012). In addition, in traditional recipes, as the amount of protein and fat increased, the water footprint values also increased (p = 0.013; p = 0.007). In improved recipes, as the amount of protein increased, the water footprint values increased significantly (p = 0.008). It was determined that greenhouse gas emission values decreased by 14.55 % in improved meat dishes, 34.89 % in seafood, and 17.21 % in vegetable dishes, while water footprint values decreased by 15.55 %, 33.82 % and 52.26 % for meat, seafood, and vegetable dishes respectively. We believe that improving and reorganizing traditional cuisines of countries will have positive effects ecologically and health-wise, and will provide important contributions to future studies. © 2025 Elsevier B.V.
The Effect of Hyperuricemia on Acute Renal Failure Due To Sepsis in Elderly Intensive Care Patients and The Relationship With Cancer
(Yuzuncu Yil Universitesi Tip Fakultesi, 2025) Açık, H.; Açık, G.; Gökçe, K.
The aim of our study is to assess hyperuricemia as an early biomarker of sepsis-related acute kidney injury and mortality in elderly cancer patients. This retrospective study was conducted on patients with sepsis, who were hospitalized in the intensive care unit (ICU), based on the quick Sequential Organ Failure Assessment (qSOFA) score. Patients were categorized i nto two groups depending on their uric acid levels. The first group had a serum uric acid level of ≥7 mg/dL, whereas the second group had a serum uric acid level of <7 mg/dL. The median age was 73.5 years, ranging from 65 to 82 years. Among the 106 patient s, 35 patients had hyperuricemia. Acute kidney injury was developed at a statistically significantly higher rate in the group of patients with hyperuricemia than in the group of patients with normal uric acid levels (p=0.019). However, mortality rates were found to be similar in both groups. According to the statistics, the group with hyperuricemia had a significantly longer length of stay in the ICU (P=0.019). Multiple models revealed that having malignancy (p=0.003; OR:5.771) and a high qSOFA score (p=0.0 001; OR:5.535) were risk factors that increased the risk of mortality. The rates of AKI development were found to be statistically significantly higher in the hyperuricemic group. The risk of mortality in elderly hyperuricemic cancer patients hospitalized in the ICU is higher than in non-hyperuricemic patients. Hyperuricemia can be used as one of the early biomarkers of sepsis-related AKI. © 2025, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Transverse Vibrations and Stability of Viscoelastic Axially Moving Rayleigh Beams Under Thermal Fields: an Analytical Approach
(Elsevier, 2025) Sichani, Farzam Fatehi; Mokhtarian, Ali; Babadoust, Shahram; Salahshour, Soheil
In this work, the flexural vibrations and stability of viscoelastic beams under axial motion and thermal fields are investigated using Rayleigh beam theory. The viscoelastic behavior is modeled through the Kelvin-Voigt and Maxwell models, and the governing differential equation is derivative utilizing Hamilton's principle. To create a more realistic model, thermal stresses in the beam are simulated using both linear and non-linear models. An innovative analytical solution method for these equations is presented, employing a power series approach to solve equations. The research provides an explicit mathematical expression for the mixed vibration modes of the beam under axial motion. Various parameters, such as rotational inertia, linear and non-linear thermal stresses, structural damping, and axial movement speed, are analyzed for their effects on the dynamic characteristics and instability of viscoelastic Rayleigh beams under axial motion. The findings indicate that incorporating rotational inertia and Rayleigh beam theory reduces the natural frequencies at low axial speeds but consistently increases the system's critical speed. Furthermore, rotational inertia induces distortions in the vibration mode shapes. Notably, the impact of rotational inertia on the second mode shape is significant, resulting in the loss of the nodal point in the second vibration mode shape of the beam under axial motion.
Interaction of Doxorubicin With Carbon Nanotubes in the Capillaries Surrounding Cancer Tumors Using Molecular Dynamics Simulation: the Impact of Ph on the Thermal Properties
(Elsevier B.V., 2025) Zheoat, A.M.A.; Al Luaibi, A.I.M.; Darraji, R.K.A.A.; Singh, N.S.S.; Salahshour, S.; Sajadi, S.M.; Hekmatifar, M.
Environmental factors, including pH, can affect the efficacy of doxorubicin, a chemotherapeutic drug that is frequently used. This study employs molecular dynamics modeling to investigate the correlation between doxorubicin and carbon nanotubes in the capillaries surrounding malignant tumors. After a period of 10 ns, the system reaches to equilibrium when the kinetic and potential energies are stabilized at 0.93 kcal/mol and 5.68 kcal/mol, respectively. The maximum density increases from 0.0033 to 0.0036 atm/Å3 as the pH increased from 3 to 11. Conversely, the shear tension decreases from 3.25 to 3.11 Pa, and the maximum temperature decreases from 391.91 to 368.77 K. The enhancement in drug stability and minimal degradation under physiological conditions was demonstrated by the decrease in temperature and shear stress that occurred with an increase in pH. The root mean square deviation and mean squared displacement also suggested that structural stability was improved at higher pH levels. This work facilitated the development of pH-responsive drug delivery devices, which improved drug stability and facilitated the controlled release of pharmaceuticals at physiological pH. These results may have a direct impact on the development of more effective cancer medications, particularly in the form of pH-sensitive drug delivery systems. This study facilitated the development of personalized therapies that could improve the stability and controlled release of chemotherapeutic medications throughout the body by regulating the interactions between doxorubicin and carbon nanotubes, thereby paving the way for future clinical research. This method had the potential to enhance the precision of drug administration, mitigate adverse effects, and enhance therapeutic outcomes in the treatment of cancer. © 2025 The Authors
Effect of Air Layer Thickness on Melting Kinetics and Heat Transfer in Horizontally Oriented Hemispherical Phase Change Material Enclosures
(Elsevier B.V., 2025) Khalaf, A.F.; Rashid, F.L.; Al-Obaidi, M.A.; Mohammed, H.I.; Ameen, A.; Agyekum, E.B.
Phase change materials (PCMs) in thermal energy storage systems often encounter unintended air gaps that critically affect performance, yet their effects in hemispherical enclosures remain unexplored. This research delves into the critical role of air layer thickness in modulating the melting kinetics and heat transfer performance of PCM within horizontally oriented hemispherical enclosures—a configuration with considerable applications for thermal energy storage (TES) systems. This research has systematically quantified how air layer thickness (0–3 mm) affects PCM melting dynamics using advanced ANSYS/FLUENT 16 simulations. The absence of an air layer (0 mm) affords the fastest melting, driven by unobstructed natural convection and conduction. In other hand, incremental air layer thicknesses (1 mm, 2 mm, 3 mm) have introduced enlightened thermal resistance, delaying melting completion by 15 %, 30 %, and 45 %, respectively. In this regard, a 3 mm air layer has exhibited the most noticeable insulating effect, overwhelming the convective flow velocities by 35–40 % and creating non-uniform temperature distributions of 18–22 °C gradients. The obtained results disclose an essential trade-off. This is specifically disclosed as while air layers can enhance insulation, they obstruct heat transfer competence, extending the melting duration from 85 min (0 mm) to 123 min (3 mm). This research delivers actionable visions for optimising air gap design in PCM-based systems, balancing thermal regulation requirements with energy storage performance. The associated results are predominantly relevant for applications necessitating detailed thermal management, such as building-integrated TES and electronic cooling, where hemispherical enclosures offer geometric advantages. © 2025 The Author(s)

Recognizing the Unexpected: a Rare Cause of Rice Bodies in Brucellosis
(Wiley, 2025) Kalender, Ayse; Akcin, Ali Izzet; Eyvaz, Nuran; Dundar, Umit; Fazli, Sakhi Ahmad
Brucella is a gram-negative zoonotic agent transmitted by consumption of raw milk and infected meat. Among musculoskeletal manifestations, axial involvement such as spondylodiscitis and sacroiliitis is well documented, while peripheral manifestations like tenosynovitis and rice bodies remain underreported. In this case, flexor tenosynovitis and associated rice body involvement due to Brucella, which developed progressive swelling, pain, and restricted movement in the wrist and third finger of the hand after a minor abrasion, were investigated ultrasonographically. As far as we know, this is the first reported case of primary brucellosis with flexor tenosynovitis and associated rice bodies demonstrated ultrasonographically in the literature.

(Institute of Electrical and Electronics Engineers Inc., 2025) Kaky, K.M.; Bilgen, S.
This study explores the potential of cellular-vehicle-to-everything (C-V2X) wireless communications in enhancing AV localization in GNSS-deprived scenarios. Specifically, we propose CV2X-LOCA, a novel unit (RSU)-assisted cooperative localization substructure utilizing only C-V2X channel state information to achieve lane-level precision. CV2X-LOCA comprises four main components: a data processing module, environment parameter correction module, coarse positioning module, and vehicle trajectory filtering module, collectively addressing challenges in dynamic C-V2X networks. Through extensive modelling we demonstrate that CV2X-LOCA attains cutting-edge localization performance even in noisy conditions, with fast-moving vehicles and sparse RSU coverage. The findings offer valuable insights for transportation agencies to make informed decisions regarding cost-effective RSU deployment in the future. © 2025 IEEE.

Effect of Osteotomy Strategy on Primary Stability and Intraosseous Temperature Rise: an Ex-Vivo Study
(BMC, 2025) Gokce Uckun, Gozde; Saygili, Sina; Cakir, Merve; Geckili, Onur
Background Primary stability is a perquisite for achieving successful osseointegration. Additionally thermal effect of implant bed preparation plays an important role in success of a dental implant. This ex vivo study was conducted to compare one step implant specific osteotomy and conventional osteotomy in terms of primary stability and thermal changes during surgery. Methods Forty eight implants were inserted into the sheep iliac crest bones each with a safe distance to each other and divided into six groups. In two of the groups implant specific osteotomy and in the remaining 4 groups conventional osteotomy was performed. In the groups, the primary stability of the trioval implants designed for the implant specific osteotomy were compared with the oval active threaded implants. The two osteotomy methods were also compared. Additionally the thermal changes during the two osteotomy methods were compared using a double-channel temperature monitoring device. Results Statistically significant differences (P <.05) were observed between the stability groups and the thermal evaluation groups (P <.05). Implant specific osteotomy revealed significantly higher stability than the conventional osteotomy (P <.001). Osteotomy without irrigation caused significantly higher thermal changes than the conventional osteotomy wit irrigation (P <.001). Conclusion Although the implant specific osteotomy reveals better primary stability, it causes higher temperature during drilling. However, since this increase is within the limits and doesn't cause a risk in terms of osseointegration, it may be used safely in clinical practice.

Precision values ranged from 0.73 to 0.98. Maxillary sinus segmentation exhibited the highest performance, while mandibular canal segmentation showed the lowest performance.ConclusionThe results demonstrate high accuracy and precision across most structures, with varying Dice scores indicating the consistency of segmentation. Overall, our segmentation model exhibits robust performance in delineating anatomical features in CBCT images, promising potential applications in dental diagnostics and treatment planning.
Potential Health Benefits of Berry Bioactives, Their Use as Nutraceuticals, and Regulatory Issues
(Elsevier, 2025) Gunal-Koroglu, D.; Ozkan, G.; Ozdal, T.; Kamiloglu, S.
As living standards have gradually improved, there has been a growing awareness of the importance of a healthy diet. This has led many people to shift their eating habits from simply seeking fullness to prioritizing nutritious diets. Recently, dietary guidelines in many countries have recommended increasing daily fruit and vegetable intake, with a particular emphasis on nutrient-rich berries. Berries are rich in nutrients and phytochemicals, which have been shown to enhance health and prevent various chronic diseases in both in vivo and in vitro studies. The primary phytochemicals in berries include phenolic compounds such as flavonoids (including anthocyanins, flavanols, and flavonols), tannins, and phenolic acids. In this chapter, we presented the potential health benefits of these berry phenolics, including their antioxidant, anticancer, antidiabetic, and antiinflammatory properties. Moreover, we discussed the use of berry bioactives as nutraceuticals and the regulatory issues related to their use. © 2025 Elsevier Inc. All rights reserved.
