Simple transmission measurements discriminate instability processes in multiple emulsions

Simple and Multiple Water Fuel Emulsions Preparation in Helical Flow

This paper presents a method of simple and multiple water fuel emulsions preparation in a liquid-liquid contactor with Couette-Taylor flow (CTF contactor). This method concerns the integration of the CTF contactor with diesel engines for the injection of just-prepared emulsions. Stable simple O/W and multiple O/W/O emulsions, both with quite narrow drop size distribution, have been prepared. Th...

Prediction of Instability in Planar Anisotropic Sheet Metal Forming Processes

In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...

Multiple Emulsions – Preparation and Stability

Multiple emulsions (W1/O/W2) with a long-term stability of at least 12 months were prepared in order to encapsulate low molecular weight bioactive substances (Mr < 2000 g/mol). The influence of the emulsifying procedure, i.e. the variation in energy input for dispersing W1/O in W2, and the influence of the emulsion composition were investigated in relation to emulsion stability and encapsulatio...

Multiple Emulsions a Coprehensive Review

Multiple emulsions are also known as emulsions of emulsions, liquid membrane system or double emulsion. These have been proposed to have numerous uses including their use for enhancement of bioavailability or as a prolonged drug delivery system. Multiple emulsions are often stabilized using a combination of hydrophilic and hydrophobic surfactants. The ratio of these surfactants is important in ...
