Dr. Arash Pakravesh research focuses extensively on advancing thermodynamic modeling through the development, refinement, and application of SAFT-type equations of state, particularly for complex fluids, supercritical systems, and industrially relevant mixtures. Key contributions include the PρT parameterization of the SAFT equation of state, which introduces an optimized framework for improving accuracy in density, pressure, and temperature predictions across diverse fluid conditions. Additional investigations examine the thermodynamic behavior of supercritical hydrogen using both cubic and SAFT-type models, offering insights essential for hydrogen storage, transportation, and energy technologies. Comparative evaluations involving friction theory, free-volume theory, entropy scaling, and Helmholtz energy scaling viscosity models further demonstrate how coupling these models with PρT-SAFT enhances prediction reliability for ethylene glycols and alkanolamine mixtures. Significant work also explores the modeling of pure, binary, and ternary mixtures of alkanolamines using multiple SAFT versions, contributing valuable data for chemical engineering processes such as gas treatment and solvent design. Moreover, upcoming studies assess the performance of PρT-SAFT, PC-SAFT, CPA, and related equations of state for predicting density, heat capacity, compressibility, speed of sound, and vapor pressure in pure ethylene glycols and their mixtures, collectively advancing the broader understanding of molecular thermodynamics in engineering science.

Dr. Kalaivanan Nagarajan | Chemistry | Young Scientist Award

Tata Institute of Fundamental Research, Mumbai | India

Dr. Kalaivanan Nagarajan research focuses on exploring the fundamental and applied aspects of light–matter strong coupling, particularly vibrational strong coupling (VSC), to understand and manipulate chemical reactivity and material properties within optical cavities. By integrating principles from physical chemistry, quantum electrodynamics, and materials science, the work investigates how molecular vibrations interact coherently with confined optical modes in Fabry–Perot cavities to form hybrid light–matter states known as vibrational polaritons. These studies reveal how strong coupling conditions can reshape potential energy surfaces, influence molecular structure, dynamics, and reaction kinetics, and ultimately enable control of chemical transformations without the need for external photoexcitation. A key highlight of this research is the demonstration that VSC can modulate phase transition behaviors, such as the glass transition temperature of polymers like polyvinyl acetate and polystyrene, providing experimental evidence of cavity-modified thermomechanical properties. Through systematic spectroscopic, thermodynamic, and theoretical investigations, the research establishes how vacuum electromagnetic fields play an active role in determining material behavior and chemical outcomes. This pioneering approach contributes to the emerging field of polariton chemistry, offering new pathways for designing energy-efficient reactions, reactivity control strategies, and material innovations driven by quantum light–matter interactions.
