Abstract: An electrolyte and a method to electroplate a metal on a substrate using the electrolyte are described. The electrolyte includes an imidazolium compound, a metal salt, and water. The imidazolium compound has formula (I) wherein R1, R2, R3, R4, and R5 are each independently selected from an H atom and an organic radical. L? is a compatible anion. The metal salt can include but is not limited to salts of the metals Li, Mg, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb, Bi, La, Ce, Al, Ag, Au, Ga, V, In, Nb, Mo, and W.

Abstract: A refrigerant system uses a cofluid of ionic liquid and CO2 as a working fluid, and is adapted to selectively bind and release CO2 molecules from the ionic fluid in exothermic and endothermic processes, respectively. The refrigerant system includes a hermetic compressor which acts as a pump for the substantially uncompressible liquid working fluid. The compressor includes electrical components (such as the electric motor and various wires and connectors) which are electrically isolated from the working fluid in order to prevent electrical shorts caused by the conductive ionic fluid. At the same time, the ionic liquid may act as a lubricating fluid for the compressor components, eliminating any need for separate working and lubricating fluids.
