Ionic liquid ion sources: characterization of externally wetted emitters.
TLDR
The feasibility of electrostatically extracting and accelerating ions from room temperature ionic liquids in a high vacuum environment is investigated using externally wetted emitters similar to those manufactured for liquid metal ion sources, made out of tungsten wire and electrochemical treated to produce a sharp tip and to increase surface wettability.About:

Triazolium-based energetic ionic liquids
TL;DR: The energetic ionic liquids formed by the 1,2,4-triazolium cation family and dinitramide anion are investigated by ab initio quantum chemistry calculations, to address the following questions: How does substitution at the triazlium ring's nitrogen atoms affect its heat of formation, and its charge delocalization.

Energy properties of an EMI-Im ionic liquid ion source
TL;DR: In this article, the identity and the energy distributions of positive and negative ions electrostatically extracted from the liquid phase in an ionic liquid ion source (ILIS) are analyzed with a time-of-flight mass spectrometer and a multi-grid retarding potential analyzer.

TL;DR: A series of hydrophilic and hydrophobic 1-alkyl-3-methylimidazolium room temperature ionic liquids (RTILs) have been prepared and characterized to determine how water content, density, viscosity, surface tension, melting point, and thermal stability are affected by changes in alkyl chain length and anion.

The room temperature ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate : Electrochemical couples and physical properties
TL;DR: In this paper, the room temperature ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIBF{sub 4}) was demonstrated as a versatile electrolyte by examining three representative electrochemical couples: ferrocene and tetrathiafulvalene oxidations and lithium ion reduction.
