Over 100 papers selected from presentations and reviewed by peers discuss such topics as synthesizing and characterizing a novel liquid crystalline polymer bearing azobenzene, an infrared imaging system based on liquid-crystal thermo-optic effects, the microwave-assisted synthesis and mesomorphic properties of novel unsymmetric imidazolium as ionic liquid crystals, the electroluminescence of naturally oxidized polypyrrole, and improving the open circuit voltage of amorphous silicon solar cells by treating the p layer with hydrogen plasma.
Some inorganic or organic acids could react directly with N-alkylimidazoles to form a new class of protic IL, which bear an acidic proton on nitrogen of the imidazolium ring.
Some specific subjects covered include ionic liquids for space propulsion, ionic liquids as vehicles for reactions and separations, spatial heterogeneity in ionic liquids, and the potential environmental impact of imidazolium ionic liquids.
