A number of processes are available: condensation-, interfacial-, suspensionand emulsion-polymerization. Suspension and emulsion polymerization are the preferred methods for the commercial production of polymer microsphere carrier particles and reference/standard particles for calibration of scientific instruments. In general, emulsion polymerization produces a smaller particle size and a narro...

background: the dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...

This study was conducted to evaluate emulsion mapping between emulsion stability and cooking yields, apparent viscosity, and hardness of reduced-fat pork emulsion systems. The reduced-fat emulsion systems were supplemented with different lipid types and brown rice bran fiber (BRF) concentrations. Compared to the control with 30% back fat, lower emulsion stability and higher cooking yield of mea...

The steady deformation and breakup of emulsion drops in a uniform electric field are considered experimentally. Due to the low volume fraction of inner drops, the emulsions can be effectively assumed as Newtonian fluids with spatial nonuniformity. The measurements of the electrical properties show that the oil-in-water (o/w) emulsion drop behaves like a conducting drop. On the other hand, the w...

Introduction: F-labelled cells provide an important new technique to evaluate in vivo the migration of implanted cells such as in stem cell therapy [1]. F-marker substances such as perfluorocarbons (PFC ) have been used for cell tracking based on F spectroscopy [2]as well as F magnetic resonance imaging (MRI). We present first results of F MRI of fibroblasts and neuroblastoma cells labeled with...

Microfluidic encapsulation platforms have great potential not only in pharmaceutical applications but also in the consumer products industry. Droplet-based microfluidics is increasingly used for the production of monodisperse polymer microcapsules for biomedical applications. In this work, a microfluidic technique is developed for the fabrication of monodisperse double emulsion droplets, where ...
