Reversible Transitions

Water is an intriguing substance. It shows sharp and reversible transitions between amorphous ices and, possibly, a liquid–liquid phase transition. Here, we discuss how this behavior is altered by the addition of solutes, such as salts and alcohols.

Liquid Liquid Phase Separation

Salt induces liquid–liquid phase separation (LLPS) of the aqueous solutions of a dendrimer. LLPS occurs by cooling at low salt concentration and by heating at high salt concentration.

Set Up

A horizontal electrohydrodynamic (EHD) liquid bridge (also known as a “floating water bridge”) is a phenomenon that forms when high voltage DC (kV·cm−1) is applied to pure water in two separate beakers. The bridge, a free-floating connection between the beakers, acts as a cylindrical lens and refracts light. Using an interferometric set-up with a line pattern placed in the background of the bridge, the light passing through is split into a horizontally and a vertically polarized component which are both projected into the image space in front of the bridge with a small vertical offset (shear). Apart from a 100 Hz waviness due to a resonance effect between the power supply and vortical structures at the onset of the bridge, spikes with an increased refractive index moving through the bridge were observed. These spikes can be explained by an electrically induced liquid–liquid phase transition in which the vibrational modes of the water molecules couple coherently.
