Chemistries in Electrosprays

Chemistries in Electrosprays

Internship Description

When a polar or non-polar liquid passes through a narrow metallic capillary (~0.1 mm), connected to electrical voltage (~3 kV), the liquid breaks into what is known as an electrospray. Electrosprays are exploited in analytical techniques, such as Electrospray Ionization Mass Spectrometry (ESIMS), to characterize ionic or neutral species in the solution. Recently, we observed that the rate of polymerization of isoprene (C5H8) was dramatically enhanced in electrosprays in comparison to reactions in condensed phase and oil-water emulsions. However, the underlying mechanisms are unclear. We would like to understand the effects of electrical voltage, temperature, capillary diameters, gas flow rates, etc., factors on the rates of reactions.​​​

Deliverables/Expectations

The VSRP intern will work with a senior graduate student and learn the following skills:

Laboratory experiments: ESIMS, voltage sources, identifying reactions of interest

Theory: basic electrostatics, data analysis, data plotting

We expect the intern to be driven by curiosity, hard working, and thrive in a multicultural work environment.​
