What is it about?

In this work, we apply photoelectron spectroscopy to study the electronic structure and mixing characteristics on either side of a liquid flatjet, formed by collision of two cylindrical jets. We demonstrate that mixing is negligible in a well-defined region after impingement, and that either face of the flatjet retains the characteristics of one of the two initial solutions. We anticipate that photoelectron spectroscopy of liquid flatjets will become a valuable tool for studying reacting species in real time.

Why is it important?

Liquid jet photoelectron spectroscopy has proven to be a powerful technique for studying the electronic structure of liquids and solutions, and in particular for water. By demonstrating the suitability of this technique for measuring liquid flatjets, we open up new possibilities to study mixed and reacting solutions and to study the formation of reaction products in real time, which would not have been possible using traditional approaches.
