Phase behavior of pseudoternary brine/alkane/alcohol-secondary alkanesulfonates systems

Lecithin Based Pseudoternary Phase Diagrams

Aim: Different promising colloidal delivery systems including microemulsions and liquid crystals could be obtained with suitable combination of oil, surfactants/cosurfactants and water. However, the main problem from a formulation point of view has been to choose the surfactants capable of forming such systems and be physiologically acceptable in the same time. To overcome the later shortcoming...

Effect of surfactant and surfactant blends on pseudoternary phase diagram behavior of newly synthesized palm kernel oil esters

BACKGROUND The purpose of this study was to select appropriate surfactants or blends of surfactants to study the ternary phase diagram behavior of newly introduced palm kernel oil esters. METHODS Nonionic surfactant blends of Tween(®) and Tween(®)/Span(®) series were screened based on their solubilization capacity with water for palm kernel oil esters. Tween(®) 80 and five blends of Tween(®) ...

Phase Behavior of Sulfonated Polystyrene Systems

INTRODUCTION Polymer blends are of great interest because they provide an economical route to design and produce novel materials that meet the challenging requirements for industrial applications. Recently, a variety of experimental and theoretical work has been conducted as a means for producing materials with improved properties compared to those of its constituents. Some of the findings sugg...

High Temperature Behavior of Dual Phase Steels

Dual phase steels with different martensite volume fraction and morphology were tensile tested at a temperature range of 25 to 5500C. Stress-strain curves of all steels showed serration flow at temperatures of 250 and 3500C, and smooth flow at the other temperatures. Both yield and ultimate tensile strengths increased with increasing testing temperature up to about 450<sup...
