Preliminary investigation on the water retention behaviour of cement bentonite mixtures [PDF]
Cement bentonite mixtures are often used to build slurry walls for the containment of both aqueous and non aqueous pollutants, due to their quite low hydraulic conductivity and relatively high ductility and strength.

Nanofiltration Separation of Aqueous Polyethyleneglycol – Salt Mixtures
To investigate nanofiltration (NF) separation for recycling polyethylenglycol (PEG) from an ion partition process using an aqueous two-phase system, fractionation performance of five different NF membranes (NF270, SR3, SR100, SR2, and BW30) with solutions of NaNO3, KClO4, and PEG 4000 in water comprising various mixtures were studied.

The microscopic structure of cold aqueous methanol mixtures [PDF]
The evolution of the micro-segregated structure of aqueous methanol mixtures, in the temperature range 300 K-120 K, is studied with computer simulations, from the static structural point of view. The structural heterogeneity of water is reinforced at lower temperatures, as witnessed by a pre-peak in the oxygen-oxygen structure factor.
