The nitrofurazone (NF) electrochemical reduction has been studied by cyclic voltammetry (CV) and square wave voltammetry (SWV) in non-aqueous medium using three different ionic liquids (IL): BMImTf2N, BMImBF4 and BMMImTf2N, having a carbon fiber microelectrode as working electrode. In all of them, two reversible cathodic peaks were recorded for NF....

A liquid-liquid transition (LLT) is a transformation from one liquid to another through a first-order transition. The LLT is fundamental to the understanding of the liquid state and has been reported in a few materials such as silicon, phosphorus, triphenyl phosphite, and water. Furthermore, it has been suggested that the unique properties of mater...

AbstractIt is established that catalytic systems based on gold nanoparticles stabilized in ionic liquids and supported on an MCM-41–type mesoporous silica show a high activity and selectivity in hydroamination of phenylacetylene with aniline, obeying Markovnikov’s rule. It is shown that the activity of the synthesized gold-containing systems grows ...

AbstractNitrogen-doped graphene nanoflakes with a high nitrogen content (6.6 at %) and developed mesoporosity were synthesized via pyridine pyrolysis. They were tested in a supercapacitor with a non-aqueous electrolyte: a 1.2 M solution of ionic liquid Et4N+TFSI− in acetonitrile. It was found that incorporation of nitrogen into the graphene layers ...

We report halogen-bonded complexes between 1-polyfluoroalkyl-3-alkylimidazolium iodides and mono-iodoperfluoroalkanes of different chain lengths or di-iodoperfluorooctane. 19 F NMR analyses revealed that the preferred stoichiometry between the donors and acceptors is 1 : 1 in the cases of the mono-iodoperfluoroalkanes, and 2 : 1 with di-iodoperfluo...

Bis(trifluoromethylsulfonyl)imidic dicationic liquids containing a disiloxane linker between the imidazole cations have been synthesized. Their thermal stability was estimated, and their melting points, viscosity, and volatility in vacuo were measured. The opportunity to use these ionic liquids as heat transfer agents in a dynamic vacuum has been s...

For the in situ resource utilization (ISRU) of asteroids, the cost-mass conundrum needs to be solved, and technologies may need to be conceptualised from first principals. By using this approach, this Review seeks to illustrate how chemical process intensification can help with the development of disruptive technologies and business matters, how th...

The Cover Feature shows the correlation between the stability and reactivity of ionic liquids (ILs). Undercutting the maximum operating temperature (MOT) the IL initially is protected. Reaching the MOT, reactive species can be formed by thermal decomposition and functionality of the IL changes. Thus IL, actually used as a solvent, can become reacta...

The Front Cover shows the spiro ‐dicubane Bi7S8 5+ in the center, accompanied by two Bi4S4 4+ hetero‐cubanes on both sides, which are shown along their threefold axis. These sulfidobismuth polycations were isolated in salts with [AlCl4]– and [S(AlCl3)3]2– anions. The starting material was Bi2S3, which is generally hard to dissolve but can easily be...
