Understanding Liquid-Liquid Phase separation and the Impact of Surfactants: Insights from Our Recent Research

In my latest research update, we delve into the intriguing role of surfactants in liquid-liquid phase separation. Our study reveals how these molecules accumulate at fluid interfaces, preventing droplet coalescence and stabilizing emulsions. We also explore the modeling of surfactant effects using adsorption isotherms and population balances. This approach allows us to predict the surface area available for surfactant adsorption and quantify its impact on phase separation.

Estimating Liquid Binary Diffusivity Coefficients: Simplified Approaches

When studying the diffusivity of non-electrolyte solutes in liquid solutions, especially at a very dilute level, two main correlations are typically used: the Wilke-Chang correlation, the Hayduk-Laudie correlation. Also, Taylor-Duss suggest an expansion to the mentioned correlations. Wilke-Chang Correlation This method helps to estimate the binary diffusivity of a solute (A) in a solvent (B). …

Continuous Stirred Tank Reactor (CSTR) Dynamics Simulation

Abstract Continuous Stirred Tank Reactors (CSTRs) play a pivotal role in the chemical and process industries due to their steady-state operational capabilities. This study delved into the influence of initial temperature on the dynamics of a CSTR system. Focusing on the reaction A+B→P, which follows a second-order rate law, the role of temperature in reaction …
