How does one identify a promising non-synthetic applicationfor ionic liquid technoU Our answer to this question four years ago was also very vague. We made some general comments that researchers on synthetic and non-synthetic applications should collaborate to broaden the range of general physicochemical properties of ionic liquids and speculated that such better data ranges would lead to the identification of new non-synthetic applications. 

A constant trend towards a better understanding of the relationship between redox - and more generally physicochemical - properties of the metallo-organic molecules and their composition and topography, involved in the recent years the building of ligands with specific architecture. ... 

In a colloidal dispersion, if the particle is a macromolecule of polyelectrolyte nature, additional properties to the general physicochemical properties may arise. The British physicist Donnan, in 1911, showed that when two solutions of electrolytes arc separated by a semlpermeable membrane, potentials arise at the junction. This happens v icn movement of atleast one of the ions through the semlpermeable membrane is hindered. Th<- hindrance may be due to the colloidal nature of the ion or the electroMe may be chcndcimmobile matrix of macromolecular nature like an ion-exchange resin on oiie side. In addition, an osmotic pressure difference between the two compartments is observed at equilibrium. Tlie explanation for these apparent anomalies was provided by Donnan and therefore the phenomenon, Donnan membrane equilibrium bears his name to this day. 

Flavonoids are characterized by having an aromatic ring with different degrees of substitution, including functional derivatives such as esters, methyl ethers, and glycosides. These structural characteristics determine the general physicochemical properties of these compounds. 

Five-membered heteroaromatic ring compounds have been extensively studied in terms of their relative reactivity and specific physicochemical properties. In particular, it is generally accepted that the degree of aromaticity follows the order... 

Because of their preferential use as detergents, the main interest in the physicochemical properties of the salts of a-sulfo fatty acid esters is related to their behavior in aqueous solution and at interfaces. In principle these are surface-active properties of general interest like micelle formation, solubility, and adsorption, and those of interest for special applications like detergency, foaming, and stability in hard water.
