Experimental connections between aqueous–aqueous and aqueous–ionic liquid biphasic systems

Thermoreversible (Ionic-Liquid-Based) Aqueous Biphasic Systems.

The ability to induce reversible phase transitions between homogeneous solutions and biphasic liquid-liquid systems, at pre-defined and suitable operating temperatures, is of crucial relevance in the design of separation processes. Ionic-liquid-based aqueous biphasic systems (IL-based ABS) have demonstrated superior performance as alternative extraction platforms, and their thermoreversible beh...

Connections between Linear Systems and Convolutional Codes

Connections between Linear Systems and Convolutional Codes

The article reviews different definitions for a convolutional code which can be found in the literature. The algebraic differences between the definitions are worked out in detail. It is shown that bi-infinite support systems are dual to finite-support systems under Pontryagin duality. In this duality the dual of a controllable system is observable and vice versa. Uncontrollability can occur on...

Experimental Investigation of Phase Inversion of Liquid-Liquid Systems in a Spray Extraction Column

An experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, CCl4/water, toluene /water + glycerol (25 % wt), toluene + CCl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. The effects of physical properties, mass transfer and column geometry...

Cyclohexane-Based Liquid-Biphasic Systems for Organic Electrochemistry

Organic chemistry research comprises three fundamental elements, including synthesis, sep‐ aration, and analysis. The long and untiring efforts of synthetic chemists have established countless useful reactions to enable the preparation of nearly anything. Beneficial and com‐ plex structures can be elaborated from abundant and simple starting materials. For example, several elegant synthetic str...
