THE EFFECT OF OILFIELD CHEMICALS ON THE SURFACE TENSION OF SURFACTANT SYSTEMS

Treated sea water is the most significant source of water and surfactant floods. The various chemicals employed in treatment plants should be compatible with surfactant systems. Based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...

Effect of tocopherol on Pluronic microemulsions: turbidity studies and Dynamic light scattering and dynamic surface tension measurements

The development and design of the biocompatible and biodegradable thermodynamically stable micellar and microemulsion transparent dispersions to reduce the free and unbounded drugs concentration in the blood is a basic challenge in field of drug efficacy and bioavailability of drugs. In the current work, solubilization capacity of the drug (Tocopherol), oil (Ethyl Butyrate), and oil+drug (1:1 m...

نگاشت همدیس در طرح‌های انگشتی سافمن- تیلور

 We studied the growth of viscous fingers as a Laplacian growth by conformal mapping. Viscous fingers grow due to Saffman-Taylor instability in the interface between two fluids, when a less viscous fluid pushes a more viscous fluid. As there was an interest in the rectangular Hele-Shaw cell, we solved the Laplacian equation with appropriate boundary conditions by means of conformal mapping tech...

A Study of Zeta Potential of Plasma Sprayed Hydroxyapatite Coating in Four Simulated Physiological Solutions

The zeta potential magnitude and the duration of its changes have been thought to be directly related to the surface reactivity, the governing of osteoconductivity and availability of valuable information in determining the anticipated in-vivo performance of implants. In this study the zeta potential of plasma sprayed hydroxyapatite (HA) was evaluated in various simulated physiological solution...
