Comparative Acoustical and Viscometric Study Of L-Alanine And L-Arginine in Aqueous Glycerol Medium: Effect of Side Chain Polarity and Charge On Molecular InteractionsBy Priyanka bhukya, Abrar Shah, Dr. Ashish Wakulkar
Abstract: The acoustical and viscometric properties of L-Alanine (neutral, nonpolar) and L-Arginine (basic, charged) in 10% aqueous glycerol have been investigated over a concentration range of 0.01 to 0.1 mol·kg⁻¹ at temperatures T = 293.15, 298.15, 303.15, 308.15, 313.15, and 318.15 K under atmospheric pressure. Experimental measurements of ultrasonic velocity (µ), density (ρ), and viscosity (η) have been used to derive adiabatic compressibility (), apparent molar volume (Φv), partial molar volume …

Investigation of Thermo-Acoustic Properties of Ethanol-Cyclohexane Binary MixtureBy Dr. Ashish Wakulkar, Priyanka bhukya, Lanjewar M. R, Shah S. A.
Abstract: The density, viscosity, and speed of sound for ethanol-cyclohexane binary mixtures were determined across mole fractions ranging from 0.1 to 0.9 using an Anton Paar DSA 5000 M within the temperature span of 288.15–318.15 K. From these experimental measurements, several thermodynamic and acoustic properties, such as isentropic compressibility, relative association, free volume, relaxation time, Gibbs free energy of activation, internal pressure, and solubility parameter, were derived. These parameters serve as …

Thermoacoustic Properties of Ethanol-n-Hexane and 1-Propanol-n-Hexane Binary Mixtures: A Comparative Study at 298.15 KBy Dr. Ashish Wakulkar, Shah S. A., Priyanka bhukya, Ban P. W.
Abstract: Using an Anton Paar DSA 5000 M instrument, measurements of density, sound velocity, and viscosity were carried out for ethanol–n-hexane and 1-propanol–n-hexane binary mixtures across mole fractions ranging from 0.1 to 0.9 at a constant temperature of 298.15 K. These binary mixtures were specifically selected to investigate the behavior of polar–nonpolar molecular interactions and how they affect the thermophysical properties of the system. The density, sound velocity, and viscosity data …

Thermo-Acoustic Investigation of Molecular Interactions in Aqueous Solutions of L-Histidine at Different TemperaturesBy Priyanka bhukya, Dr. Ashish Wakulkar, Prof. Shaukat Shah
Abstract: The present study investigates the acoustic and thermodynamic behavior of aqueous solutions of L-Histidine across a concentration range of 0.01 m to 0.1 m and temperatures varying from 293.15 K to 318.15 K in 5 K intervals. Ultrasonic velocity (μ), density (ρ), and viscosity (η) measurements wereconducted with high precision to understand the solution behavior under different thermal conditions.Temperature constancy during measurements was ensured using a refrigerated circulatory bath withwater …
