Seawater-immersed glass-polyester composites with optimized mechanical properties Issam Touil, Rania Saadeh, Maha S. Al Soudi, Ahmad Qazza, N. F. M. Noor, Nassima Sotehi, Mohamed Kezzar Scientific Reports, 2026 Composites are engineered materials widely used in marine applications due to their excellent durability, strength, practicality, and efficiency. However, prolonged exposure to seawater can cause irreversible degradation. In this study, the maximum stress, strain at break, and tensile modulus of composite materials made from unsaturated polyester reinforced with glass fiber (CMPG) are investigated. Tensile testing in accordance with EN ISO 527 was performed on samples fabricated with 1-layer and 3-layer fiber configurations and varying fiber areal densities (300, 450, 500, and 600 g/m²). Seawater immersion times of 3, 21, and 30 days were applied to assess environmental effects. The results showed that the mechanical properties deteriorated with increased immersion time. For example, the maximum stress decreased by up to 28% after 30 days of seawater immersion compared to dry samples. The 3-layer samples exhibited higher tensile strength than 1-layer samples across all conditions. Additionally, samples with higher fiber content (e.g., 600 g/m²) absorbed less seawater and showed less dimensional swelling than lower-density counterparts. The thickness of 1-layer composites increased from 2.00 mm to 2.81 mm after 30 days, while 3-layer samples increased up to 2.95 mm, primarily due to seawater diffusion into voids. A multiple regression model was developed to predict mechanical properties as a function of fiber number, areal density and immersion time, achieving high accuracy (R² > 0.94). Analysis of variance (ANOVA) confirmed that immersion time had the most statistically significant effect (p < 0.01) on tensile performance. FTIR analysis revealed chemical degradation and shifts in functional groups due to prolonged seawater exposure. These findings confirm that CMPG composites are susceptible to environmental degradation and a careful material selection and surface treatments are essential for long-term marine applications.
A Hybrid Approach for Solving Fractional Caputo Partial Differential Equations with Convergence Analysis Rania Saadeh, Abdelilah Kamal. H. Sedeeg, Ghassan Abufoudeh, Ahmad Qazza, Mohamed Hafez Statistics Optimization and Information Computing, 2026 In this research, fractional Caputo partial differential equations are addressed using the q-Homotopy analysis method merged with the Sawi transform method through the construction of a novel algorithm. This approach combines the Sawi transform with the q-Homotopy analysis method to demonstrate how complex fractional differential equations can be solved analytically in a straightforward manner. The proposed algorithm illustrates the effectiveness of applying the Sawi transform in conjunction with the q-Homotopy method to overcome the challenges associated with handling nonlinear terms numerically. Several examples are provided to verify the accuracy and efficiency of the proposed approach. The results indicate that the method converges to the exact solutions when suitable parameters are chosen. Therefore, the proposed method proves to be a robust and flexible algorithm for solving nonlinear fractional partial differential equations.
Double ARA–Generalized Laplace Method for Solving (2 +1)–Dimensional Nonlinear Singular Pseudoparabolic Equations Rania Saadeh, Abdelilah Kamal. H. Sedeeg, Ahmad Qazza, Osama Ala′yed Journal of Applied Mathematics, 2026 This study presents a novel triple integral transformation, called the double ARA–generalized Laplace transform (DAGLT), and applies it to solve (2 + 1)–dimensional singular pseudoparabolic equations in both linear and nonlinear forms. The work begins by outlining the fundamental definitions, theorems, and characteristics of the single ARA and generalized Laplace transforms, then proceeds to unify them into a single framework (DAGLT). Detailed derivations of the core properties linearity, shifting, and partial derivative transforms demonstrate the theoretical soundness and broad applicability of DAGLT. Utilizing the Adomian decomposition method merged with this new transform, the paper presents an efficient procedure for obtaining closed‐form or series‐based solutions to challenging singular pseudoparabolic partial differential equations. Several illustrative examples showcase the effectiveness of the proposed technique, confirming that its solutions align with known results in the literature. The main advantages of the method are that it can handle singularities, and it improves the convergence. This study is promising for dealing with different models of multidimensional partial differential equations that arise in physical science and models.
Exploration of a New Approach Related to Atangana-Baleanu Derivatives for Solving Fractional Partial Differential Equations Rania Saadeh, Ahmad Qazza, Abdelilah Kamal H. Sedeeg, Ghassan Abufoudeh International Journal of Mathematical Engineering and Management Sciences, 2025 This paper explores the application of fractional calculus to solve fractional partial differential equations (FPDEs) using the Sawi transform in combination with the Atangana-Baleanu fractional derivative. The Atangana-Baleanu derivative, formulated in both Caputo and Riemann-Liouville senses, offers a powerful tool for modeling memory and hereditary properties in complex physical systems. We extend the Sawi transform’s operational framework to efficiently handle FPDEs by deriving new properties and convolution theorems relevant to the fractional derivatives. The combination of the Sawi transform with the homotopy perturbation method yields a novel approach, termed the Sawi-Transform-Homotopy Perturbation Method, which facilitates the analytical solution of nonlinear FPDEs. The proposed method was validated using fractional Kolmogorov and Rosenau-Hyman equations, achieving exact solutions in some cases and series solutions with rapid convergence in others. Numerical results demonstrated a reduction in computational complexity by approximately 30% compared to traditional methods, highlighting its efficiency and accuracy. This work underscores the utility of fractional calculus in solving real-world problems and advances analytical techniques for solving FPDEs using modern fractional operators.
A comparative analysis of the impact of different treatments on Luffa Cylindrica fiber tensile properties Rania Saadeh, Ayman A. Dawod, Ibrahim Mahariq, Ahmad Qazza, Abdelkader Khentout, Mohamed Kezzar, Mohamed Rafik Sari Plos One, 2025 In recent years, there has been a growing demand for environmentally friendly materials as alternatives to synthetic fibers, which pose significant environmental hazards due to their non-biodegradability. Natural fibers, such as Luffa Cylindrica, have gained attention due to their sustainability, lightweight properties, and biodegradability. However, their poor mechanical performance in composite applications limits their widespread use. The novelty of this study lies in the exploration of various treatments aimed at improving the tensile properties of Luffa Cylindrica fibers (LCFs), a relatively under-explored natural fiber. The research investigates the effects of immersion treatments in mineral water, seawater, vinegar (CH₃COOH), sodium bicarbonate (NaHCO₃), and ethanol (C₂H₆O) on the tensile strength, surface morphology, and absorption properties of these fibers. The study highlights that untreated LCFs exhibit superior tensile strength (5.59 MPa) compared to treated fibers. Additionally, the statistical analysis utilizing two-parameter Weibull distribution offers novel insights into the mechanical properties of treated LCFs, confirming significant variations in fiber behavior with different treatments. This study contributes to the understanding of surface modifications that enhance the performance of Luffa Cylindrica fibers in composite materials, a promising step towards their industrial application.
Role of ternary hybrid nanoparticle and EMHD on boundary layer flow with stretching-shrinking plate: Optimization analyses using RMS Ibrahim Mahariq, Rania Saadeh, Farhan Lafta Rashid, Ahmad Qazza, Hamiden Abd El-Wahed Khalifa, Mohamed Kezzar, Haifa Alqahtani, Mohamed Rafik Sari Results in Physics, 2025 • The use of hybrid nanoparticles enhances heat transfer rate and reduces skin friction in EMHD boundary layer flow. • Optimization analyses reveal maximum thermal performance and flow improvement under specific electromagnetic and radiation conditions. • Hybrid nanoparticles demonstrate a synergistic effect, leading to improved thermal and fluidic properties compared to individual nanoparticles. • A notable decrease in skin friction coefficient is observed, indicating better flow characteristics. • The combined statistical and numerical approach effectively identifies optimal parameters for thermal management systems. In this present work the statistical and numerical analysis to optimizing the role of ternary hybrid nanoparticle (THNP) (i.e. T i - S W C N T - M W C N T ) on heat transfer of electromagnetohydrodynamic (EMHD) boundary layer flow with different effects (i.e. magnetic and electrical fields, stretching/shrinking and radiation source). The partial differential equations (PDEs) are transformed into model is simplified nonlinear ordinary differential equations using similarity transformation. The ordinary differential equations (ODEs) was numerically using the Runge-Kutta-Fehlberg method and the statistically analysis using the correlation analysis, probable error estimation, Regression, analysis of variance (ANOVA) and Response Surface Designs ( L 15 ). The findings are the optimization the role of THNP in both the local Nusselt number (Nu) and Skin friction coefficient ( C f ) impacted by the pertinent dimensionless characteristics for the considered flow case using RMS method. From the results, the volume fractions of 4% for both Ti, SWCNT, and MWCNT improve both thermal and fluidic properties of the nanofluid and show a combined effect of the nanoparticles. This study is marked by a significant decrease in the C f which implies a better flow characteristics for the hybrid nanoparticles case. Optimum conditions were achieved in the maximum value of the N u thus depicting high thermal enhancement and an enhanced cooling capability, which is very essential in thermal management systems.
Dynamics of the Gierer–Meinhardt reaction–diffusion system: Insights into finite-time stability and control strategies Ahmad Qazza, Issam Bendib, Raed Hatamleh, Rania Saadeh, Adel Ouannas Partial Differential Equations in Applied Mathematics, 2025 This study delves into the dynamics of the Gierer-Meinhardt (GM) reaction–diffusion (RD) system, focusing on finite-time stability (FTS) and synchronization (FTSYN) within integer-order spatiotemporal partial differential frameworks. Unlike traditional studies emphasizing asymptotic stability, this work presents novel insights into achieving synchronization and equilibrium within a predefined finite time. By leveraging Lyapunov-based methodologies, sufficient conditions are derived to guarantee FTS and transient behavior control. A synchronization scheme for master–slave systems is developed, ensuring coherent dynamics within a finite time frame. Numerical simulations, employing the finite difference method, validate the theoretical findings and demonstrate the practical applications of the proposed strategies in systems requiring stringent temporal constraints. The results highlight significant advancements in RD modeling, with implications for biological pattern formation, robotics, and distributed networks, paving the way for innovative control solutions in complex dynamical systems.
Effects of variable thermo-physical characteristics on MHD ternary hybrid second-grade nanofluid in rotating Jeffery-Hamel flow Ibrahim Mahariq, Rania Saadeh, Farhan Lafta Rashid, Ahmad Qazza, Mohamed Kezzar, Hamiden Abd El-Wahed Khalifa, Mohamed Rafik Sari International Journal of Thermofluids, 2025 This research work presents the combined effect of variable electrical and thermal conductivity on the heat transfer of ternary hybrid nanofluids in second-grade flow between rotating non-parallel plates. Furthermore, this research work considers variables such as a rotating channel, non-linear solar radiation, sink/source conditions and the effects of stretching-shrinking walls. We examine a polymer-base fluid that contains hybrid nanoparticles. The fundamental equations undergo transformations from PDEs to ODEs through the use of similarity transformations. The Explicit Runge Kutta Method has numerically solved the computational problem; we validate the present findings in specific cases by comparing them with results from the HAM-based Mathematica package and literature references. We graphically display the impacts of physical factors on temperature, velocity, and engineering parameters. We also examine and demonstrate the impact of multiple variables on the engineering parameters. When it comes to improving heat transfer, this ternary hybrid nanofluid (THNF) does a much better job than the other nanofluids talked about in this research article. The results show that there is a big boost in thermal efficiency, especially when different flow rates are used.
