Abstract:
... Determination of methamphetamine in forensic laboratories is a major issue due to its health and social harm. In this work, a simple, sensitive, and environmentally friendly method based on ionic liquid dispersive liquid–liquid microextraction combined with high‐performance liquid chromatography was established for the analysis of methamphetamine in human urine. 1‐Octyl‐3‐methylimidazolium hexaflu ...

Subject:
additives; ambient temperature; fuels; ionic liquids; liquids; oxidants
Abstract:
... A family of hydride-rich bis(borano)hypophosphite-based ionic liquids was developed, which showed good water stability at room temperature and unexpected hypergolic reactivity with oxidizers. These ionic fluids have exhibited the shortest ignition delay times so far, demonstrating their application potential as hypergolic fuels or additives in liquid bipropellants. ...

Subject:
fluorescence; humans; ionic liquids; methamphetamines; paper; urine
Abstract:
... A low cost sensing paper chip supporting an ionic liquid and a fluorescent indicator agent was developed to perform a rapid and ultrasensitive in-site methamphetamine test in human urine. The extraction ability of ionic liquids for methamphetamine, fluorescence behaviour of the system, and performance of the sensing paper were emphasized. ...

Abstract:
... A family of hydrophobic borohydride-rich ionic liquids was developed, which exhibited the shortest ignition delay times of 1.7 milliseconds and the lowest viscosity (10 mPa s) of hypergolic ionic fluids, demonstrating their great potential as faster-igniting rocket fuels to replace toxic hydrazine derivatives in liquid bipropellant formulations. ...
