Assist. Prof. Dr. Hesham Khalaf dynamical systems research encompasses the analytical and numerical investigation of chaotic, hyperchaotic, fractional-order, and distributed-order models, with emphasis on understanding system behavior across different dimensions. Core contributions include examining symmetry properties, identifying equilibrium points, and performing stability, multistability, and bifurcation analyses to reveal transitions between periodic, chaotic, and hyperchaotic states. Advanced synchronization techniques—such as modulus-modulus, N-tuple compound, dual combination, and distributed-order synchronization—are applied to explore how distinct nonlinear systems interact, converge, or desynchronize under various coupling schemes. These synchronization strategies support practical applications in secure communications, image encryption, neural networks, circuit implementation, and control systems. Additional work investigates fractional-order derivatives and distributed-order operators, which capture memory effects and enhance the modeling of real-world processes. Research includes proposing new high-dimensional fractional-order hyperchaotic systems, studying their dynamic features, and applying them to grayscale and color image encryption. Numerical simulation methods, MATLAB-based modeling, and system dynamics tools are used to validate analytical results and visualize attractor structures. Further studies explore dynamical behaviors of classical models such as the Lorenz system, detuned laser models, and complex-valued chaotic systems, contributing to the advancement of applied mathematics, complex systems analysis, and modern chaos theory.

Ms. Nabila Tabassum research trajectory focuses on the intersection of computational materials science, catalysis, and high-temperature materials engineering, emphasizing atomistic simulations and experimental validation for sustainable technological advancement. The work encompasses Density Functional Theory (DFT) and Molecular Dynamics (MD) simulations for understanding the structural, mechanical, and thermal behavior of High Entropy Alloys (HEAs), High Entropy Ceramics (HECs), and High Entropy Oxides (HEOs), specifically for applications in thermal barrier coatings and energy systems. The studies explore thermal stability, phase transformations, and electronic properties of multi-component alloys such as AlCoCrFeNi, contributing to the prediction of thermodynamic behavior and optimization of mechanical strength under extreme conditions. Experimental research complements computational findings through synthesis, sintering, and characterization of high entropy materials, bridging modeling with practical performance. Additional work includes catalytic conversion of ethanol and methanol into hydrocarbons, glycerol reforming for hydrogen generation, and development of amine–ionic liquid-based solvents for CO₂ capture, aligning with global sustainability goals. The outcomes, disseminated through peer-reviewed journals, book chapters, and international conferences, demonstrate a cohesive integration of computational chemistry, thermomechanical modeling, and green energy research, advancing the understanding and design of next-generation materials for energy-efficient and environmentally resilient applications.
