Three solutions of an ionic liquid ferrofluid (ILFF) using 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM-NTf2) as the carrier liquid were emitted from a capillary electrospray source and the resulting beam was measured using a time-of-flight mass spectrometer (TOF-MS). The solutions had 3.04, 5.98, and 8.80 wt% iron oxide nanoparticles making them susceptible to magnetic f...

Planar electrochemical double-layer capacitors (supercapacitors) are strategic elements for the realization of miniaturized autonomous devices requiring energy storage and conversion capabilities. In particular, supercapacitors fabricated with nanoporous carbon electrodes ionic liquids as electrolytes very promising a wide range applications. The understanding control interactions liquid porous...

An ionic liquid ferrofluid (ILFF) using 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM-NTf2) as the carrier liquid was emitted from the peak formed via the Rosensweig instability and the electrospray beam was measured using quadrupole and TOF mass spectrometry. The Rosensweig instability peak source (RIPS) was found to operate in three stable emission current modes: transie...

Aqueous electrolytes are very effective for supercapacitor applications but their narrow electrochemical potential window (∼1 V) and associated limited energy currently limits use. Here, we demonstrate a new strategy to enlarge the by designing an artificial interface ( ai ). An was achieved via mixture of siloxanes doped with ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfony...

Helium ion (He(+)) beam produced by a heavy ion linear accelerator was used to simulate α-rays for studying the radiation effect on 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ionic liquid ([C4mim][NTf2]). The water-soluble radiolytic products of [C4mim][NTf2] under He(+) beam irradiation were analysed, and it was found that they were similar to those by γ-ray irradiation, but...

Reprocessing tailings for gold recovery is generating new low-grade refractory secondary tailings. Unlocking trapped within these potentially holds additional economic value. In this study, the use of supercritical carbon dioxide (scCO2) at 100 bar and 40 °C extraction from such a sample (0.27 g Au/t) was investigated. The research identified screened following ligands as suitable extractants i...

Two new samples of poly(amide-imide)/nanocomposites containing bicyclo segment and dibenzalaceton moiety in the main chain were synthesized by a solution intercalation technique. Poly(amide-imide) (PAI) 8 as a source of polymer matrix was synthesized by the direct polycondensation reaction of N,N´-bis(4-carboxyphenyl)bicyclo[2,2,2]oct-7-ene-2,3,5,6-tetracarboxylic diimide 3 with 2,6-bis(4-amino...
