“…A few ILs were previously subjected to variable intensities of gamma irradiation [16]. One IL was subjected to alpha, beta, and gamma irradiation (alpha dose= 1 kGy, beta and gamma dose= 400 kGy) [17]. In all previous works, the results showed minimal changes to the physical properties, (i.e., calculated G-values, NMR shifts, spectroscopic shifts, etc.)…”

Summary.The electrochemical properties of ionic liquids (ILs) make them attractive for possible replacement of inorganic salts in high temperature molten salt electrochemical processing of nuclear fuel. To be a feasible replacement solvent, ILs need to be stable in moderate and high doses of radiation without adverse chemical and physical effects.Here, we exposed seven different ILs to a 1.2 MGy dose of gamma radiation to investigate their physical and chemical properties as they related to radiological stability.

“…They have very unique properties, such as negligible vapor pressure, excellent solvation ability and high thermal stability (Welton, 1999;Wasserscheid and Welton, 2003;Rogers and Seddon, 2003;Ranke et al, 2007). One important application of ionic liquids is as a medium for the processing of spent nuclear fuel (Allen et al, 2002;Harmon et al, 2001;Shkrob et al, 2007). Successful use of ionic liquids in radiation environments requires an understanding of radiation chemistry of ionic liquid (Grodkowski and Neta, 2002a;Grodkowski and Neta, 2002b;Grodkowski and Neta, 2002c).…”

We examined formation of solvated electrons in several ionic liquids composed of ammonium, pyrrolidinium and piperidinium cations by observing absorption spectra in the visible and near-infrared regions using pulse radiolysi. We also examined reactions of the solvated electrons with imidazolium cations in the ionic liquids. The reaction rate constants were an order of magnitude faster than the diffusion limited rate calculated from the viscosity. The electrons before full solvation (dry electrons) reacted efficiently with the imidazolium cations . These observations suggest that the electrons in the ionic liquids can move easily before solvation. The scavenging of the dry electron by the imidazolium cation was also examined using C2-alkylated-imidazolium cations. It is found that the alkylation of imidazolium suppresses the reactivity with the dry electron.

“…Uniting the properties of imidazolium derivatives, which have low melting points, low volatility, inflammability, high chemical stability, tunable conductivity, and wide electrochemical windows, with those of liquid crystals, which have many forms of labile microscopic ordering, raises fascinating prospects. 5,6 Electrodeposition of copper is essential for a variety of industrial and decorative purposes, including large-scale use in the electronic industry for the production of printed circuit boards, and electrotypes in the printing industry. For copper plating, cyanide based electrolytes are most widely employed and are highly corrosive and suffer from several drawbacks including, toxicity, high energy consumption, and air pollution.…”

A dense and adhesive Cu layer was successfully electrodeposited on mild steel in a copper chlorideof copper nucleation is studied using cyclic voltammetry and chronoamperometry. It is observed that 3D-instantaneous nucleation leads to a bright nano-structured deposit. The morphology of the deposit was characterized SEM and X-ray diffraction techniques. The deposition method was found to take place in an environmentally friendly green electrolyte without co-ligands such as cyanide and volatile toxic solvents.
