Synthesis and process optimization of colloidal unimolecular polymer, cup, particle formation, and its interfacial surface tension behavior
… system that was useful for studying the interfacial behavior of pure aqueous nanoparticles using a maximum bubble pressure tensiometer. The equilibrium surface tension shows a dependence on concentration and the charge density of the CUP particle. The equilibrium surface tension becomes …

Determining the surface tension of gas-liquid interfaces through metadynamics
The measurement of surface tension γ provides information on the behaviour of phases at an interface. γ can be determined both experimentally and through computer simulation. Here, a gas-liquid interface is constructed and simulated in order to determine the value of gas-liquid interfacial surface …

Computational methods for two-phase flow with soluble surfactant
… so that the bulk-interface surfactant exchange, surface surfactant concentration, and interfacial surface tension can be evaluated to determine the drop's dynamics and evolution. To resolve this computational difficulty, the dynamics of the transition layer are modeled by a leading order singular …

Vibration-Induced Atomization Of Liquids With Application To Ultrasonic Medical Nebulizers
… therapy. The formation of standing waves on the surface of this sort of thin film have an oscillating frequency that is roughly half the driving frequency and a wavelength that is equal to a function of the ultrasonic driving frequency, fluid density, and interfacial surface tension. The standing …

Surface Free Energy Characterization of Powders
… angle measurements were conducted to study the surface chemistry of powdered minerals. The contact angle measurements were conducted on both flat and powdered talc samples, and the results were used to determine the surface free energy components using Van Oss-Chaudhury-Good (OCG) equation. It …
