The interaction of polar liquids with moderately strong fields (kV/cm) has been studied extensively within the field of electrohydrodynamics (EHD). EHD liquid bridges like the floating water bridge have provided unique insights into the non-equilibrium molecular physics of polar liquids such as water. Whereas on the molecular scale water can be described by quantum mechanics, there is a conceptual gap at mesoscopic scale that is bridged by a number of theories including quantum mechanical entanglement and coherent structures in water. Much of the phenomenon is already understood, but even more can still be learned from it, since such “floating” liquid bridges resemble a small high-voltage laboratory of their own: the physics of liquids in electric fields of some kV/cm can be studied, even long-time experiments are feasible since the bridge is in a steady-state equilibrium and can be kept stable for hours. It is also an electro-chemical reactor where compounds are transported through by the EHD flow, enabling the study of electrochemical reactions under potentials which are otherwise not easily accessible. Last but not least, the bridge provides the experimental biologist with the opportunity to expose living organisms such as bacteria to electric fields and proton currents without killing them in order to study the influence of this special environment on their behavior and their genome.
This Special Issue will provide a broad platform for regular and review papers on the numerous up-to-date and multidisciplinary advances that are currently being achieved in the continuously growing area of liquid bridging and electrified liquids. Topics of interests include, but are not limited to:
- Physico-chemical studies of electrohydrodynamic phenomena in general;
- Molecular studies, spectroscopy, and simulation of liquids in strong electric fields;
- Chemical reactions in strong electric fields and gradients;
- Liquid mesoscale dynamics studies;
- Microbiological and biochemical studies in electrohydrodynamic environments;
- Neutron, X-ray, Raman, and Brillouin scattering studies of electrified liquids;
- Microgravity studies of electrified liquids;
- Infrared studies of electrified water;
- NMR, MRI, and ESR studies of electrified liquids;
- (Laser-)optical investigations and visualizations of electrohydrodynamic bridging and related phenomena.
It is our hope that a multidisciplinary collection of contributions will significantly accelerate the progress in this field due to the collaborative fostering of synergistic insights.

1. Title: Electrically induced liquid-liquid phase transition in a floating water bridge identified by refractive index variations
Authors: Elmar C. Fuchs, Giuseppe Vitiello, Adam. D. Wexler and Jakob Woisetschläger
Abstract: A horizontal electrohydrodynamic (EHD) liquid bridge (aka “floating water bridge”) is a phenomenon that forms when high voltage DC (kV/cm) 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 a interferometric set-up line pattern placed in the background of the bridge is split into a horizontally and a vertically polarized component which are both into the image space in front of the bridge with a small vertical offset (shear). Apart from a 100Hz waviness due to a resonance effect between the power supply and vortical structures at the onset of the bridge, refractive index spikes move through the bridge. Both the spikes and the small anisotropy can be explained by an electrically induced liquid-liquid phase transition in which the vibrational modes of the water molecules couple coherently.
