Thermodynamic Stability of Water-in-oil Emulsions
It is well known that colloids can show phase transitions similar to the ones observed in molecular systems. Colloid-diluted and colloid-concentrated phases can coexist in thermodynamic equilibrium at certain conditions. In a previous work, the authors of this research have used this concept to study petroleum emulsions stability, applying thermodynamic perturbation theories to calculate a phas...
متن کاملEmulsion Droplet Sizing Using Nmr: Application to Water-in-crude Oil Emulsions
Emulsion droplet sizing is an essential measurement requirement of a very broad range of industries including food, pharmaceuticals, personal care products, agrochemicals and crude oil dispersions. Nuclear magnetic resonance (NMR), courtesy of its ability to measure restricted self-diffusion via application of pulsed field magnetic field gradients (PFG), is able to readily measure emulsion drop...
متن کاملInfrared Spectroscopy of Bilberry Extract Water-in-Oil Emulsions: Sensing the Water-Oil Interface
Water-in-oil (w/o) emulsions are of great interest in many areas of the life sciences, including food technology, bioprocess engineering, and pharmaceuticals. Such emulsions are complex multi-component systems and the molecular mechanisms which lead to a stable emulsion are yet to be fully understood. In this work, attenuated total reflection (ATR) infrared (IR) spectroscopy is applied to a ser...
متن کاملData on the physical characterization of oil in water emulsions
This article contains experimental data and images for the physical characterization of oil in water emulsions. Mentioned data are related to the research article "Effect of stabilizers, oil level and structure on the growth of Zygosaccharomyces bailii and on physical stability of model systems simulating acid sauces" (A.L. Zalazar, M.F. Gliemmo, C.A. Campos, 2016) [1]. Physical characterizatio...
متن کاملCoagulation and electrocoagulation of oil-in-water emulsions.
In this work the efficiencies of the chemical and the electrochemical break-up of oil-in-water (O/W) emulsions with hydrolyzing aluminium salts are compared. It has been obtained that the efficiency of the processes does not depend directly on the dosing technology, but on the total concentration of aluminium and pH. This latter parameter changes in a different way in the chemical and the elect...
