In 1914, John Zeleny published work on the behaviour of fluid droplets at the end of glass capillaries. [5] This report presents experimental evidence for several electrospray operating regimes (dripping, burst, pulsating, and cone-jet). [6] A few years later, Zeleny captured the first time-lapse images of the dynamic liquid meniscus. [7]
The electrospray ionization technique was first reported by Masamichi Yamashita and John Fenn in 1984, [3] and independently by Lidia Gall and co-workers in Soviet Union, also in 1984. [4] Gall's work was not recognised or translated in the western scientific literature until a translation was published in 2008. [4]
A colloid thruster (or "electrospray thruster") is a type of low thrust electric propulsion rocket engine that uses electrostatic acceleration of charged liquid droplets for propulsion. In a colloid thruster, charged liquid droplets are produced by an electrospray process and then accelerated by a static electric field.
This cone was described by Sir Geoffrey Ingram Taylor in 1964 before electrospray was "discovered". [1] This work followed on the work of Zeleny [2] who photographed a cone-jet of glycerine in a strong electric field and the work of several others: Wilson and Taylor (1925), [3] Nolan (1926) [4] and Macky (1931).

Ion traps work by using this force to confine ions in a small, isolated volume of space so that they can be studied or manipulated. Although any static (constant in time) electromagnetic field produces a force on an ion, it is not possible to confine an ion using only a static electric field. This is a consequence of Earnshaw's theorem.
Extractive electrospray ionization (EESI) [1] [2] is a spray-type, ambient ionization source [3] [4] [5] [6] [7] in mass spectrometry that uses two colliding aerosols ...
[50] [51] [52] Taylor’s work contributed to electrospinning by mathematically modeling the shape of the cone formed by the fluid droplet under the effect of an electric field; this characteristic droplet shape is now known as the Taylor cone. He further worked with J. R. Melcher to develop the "leaky dielectric model" for conducting fluids.
Desorption electrospray ionization (DESI) is an ambient ionization technique that can be coupled to mass spectrometry (MS) for chemical analysis of samples at atmospheric conditions. Coupled ionization sources-MS systems are popular in chemical analysis because the individual capabilities of various sources combined with different MS systems ...
