Sheng Dai, leader of Nanomaterials Chemistry Group and senior research scientist at Chemical Sciences Division of Oak Ridge National Laboratory (ORNL) and adjunct professor at the University of Tennessee at Knoxville (UTK), received his PhD in chemistry from UTK in 1990. He has authored or coauthored more than 180 peer-reviewed journal or book publications. He currently holds five U.S. patents. His research interest includes chemical synthesis of novel materials, separation, catalysis, sensor development, and molecular recognition. Many of these publications are in the area of ionic liquids. 

Prominent exceptions are studies on the liquid crystal phase formation and self-assembly of two-dimensional disc- or sheet-like nanomaterials such as the organization of nanodiscs or nanoplatelets into nematic, smectic, or columnar morphologies [263-270] (see Fig. 2 for an example of the self-assembly of nanoclay in aqueous suspensions) or the synthesis of CuCl nanoplatelets from ionic liquid crystal precursors as described by Taubert and co-workers [271-273]. 

In ionic liquids the situation seems to be totally different. It was surprising to us that the electrodeposition of metals and semiconductors in 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide delivers nanocrystalline deposits with grain sizes varying from 10 to 200 nm for the different materials, like Si, Al, Cu, Ag and In, investigated to date. It was quite surprising in the case of Al deposition that temperature did not play a tremendous role. Between 25 and 125 °C we always got nanocrystalline Al with similar grain sizes. Similar results were obtained if the deposition was performed in tri-hexyl- tetradecylphos-phonium bis (trifluoromethylsulfonyl) amide. Maybe liquids with saturated nonaromatic cations deliver preferentially nanomaterials this is an aspect which, in our opinion, deserves further fundamental studies. 

The strategy of self-assembly could be applied to open up developments in molecular-based nanomaterials. We believe that the combination of ionic liquids and biomolecules, organic molecular self-assemblies and inorganic nanomaterials, can lead to new dimensions in materials science.

ILs than in aqueous or conventional organic solvent. This can probably be attributed to cation/jr-electron interactions [79]. Also, the high dielectric constant of ionic liquids may be an important factor in dispersibility of nanomaterials since it leads to shielding of the van der Waals interactions.

Ionic liquid (IL) possesses tunable behaviors based on asymmetric ion-pair combinations. Along with its tmique characteristics, such as high conductivity and wide potential window, it will be desirable to applying IL into the fields of bio-electrochemistry [29]. Incorporating IL with nanomaterials (metallic nanoparticles and carbon materials) into the development of modified... 

Rapid changes in material science such as nanomaterials, graphene, conductive polymers (both ionic and electronic), and ionic liquids will open battery designs to new formats such as thin printed and battery on board, nonreplaceableprimary batteries [7,8]. These trends, further coupled with the rise in popularity of low-power applications, may transition some of today s secondary electrochemistries into primary applications without the added cost of charge control systems required for secondary batteries.

Two distinct groups of experimental techniques were presented in COlL-2 to study the behaviour of different solutes in ionic liquids, spectroscopic and thermodynamic, giving access to different scales of the properties studied - one microscopic and the other macroscopic. It was possible to explain microscopically the phase behaviour of ionic liquid solutions by balancing the effects of the solute-solvent interactions and the dynamics of the solutions. Bases were established to assess the microscopic mechanisms responsible by the properties observed and so to open the way to the rapid advancement of the field contributing to the development of novel applications in a growing variety of disciplines including catalysis, synthesis, nanomaterial synthesis or pharmaceutics.
