In this disclosure, transition and rare earth metal-based magnetic ionic liquids (MILs) are successfully prepared in a two-step synthesis and used to extract viable bacteria from a liquid sample. The disclosed MILs are extremely hydrophobic MILs and were insoluble in aqueous solution at 0.01% (v/v). Furthermore, these MILs were miscible in a variety of polar and non-polar organic solvents. Moreover, these MILs possess low viscosity and increased magnetic susceptibility. These MILs possess unique characteristics that can have great potential uses in various chemical applications such as extraction solvents in LLE, liquid electrochromic materials (Co-based MILs), and novel reaction media for organic synthesis.

The present invention relates to the formation of a stable dianionic π-dimer-[TCNE].sub.2.sup.2− (TCNE-tetracyanoethylene) at ambient conditions that exhibits unusually intense white emission over the entire visible spectral range (400-800 nm) and has application in designing white light emitting devices. Particularly, the present invention relates to a process for the preparation of stable dimer in an organic solvent upon aging at room temperature, in the presence of anions such as Br−, Cl−, SCN−, which reduces the TCNE to a TCNE anion radical (TCNE..sup.−) which subsequently dimerizes to form the stable dianionic dimer upon aging. More particularly, the dimer formed in this invention opens a new class of materials to design white light emitting devices having high intensity over the entire visible spectral range. The dimer also forms electron transfer salts used to develop new molecule-based metals, superconductors, and magnets.

A continuous wire that includes a wound inductance from a first yarn material formed of filaments or nanotubes, the first yarn being doped with or including a first material that causes it to be electrically conductive and a second yarn formed of material filaments or nanotubes that is electrically insulating and may include magnetic particles wound with the first yarn in bifilar fashion or both yarns wrapped in a bifilar fashion around an insulating core yarn which may include magnetic particles to increase the inductance of the wire. The doping and electrical conductance of the yarns can be varied along the length of the wire to integrate sections of lumped electrical conductance and inductance.
