Room-temperature ionic liquids are new emerging green material. They have good chemical and thermal stability, negligible vapor pressure, nonflammability, high ionic conductivity, transparence, and a wide electrochemical window. So the ionic liquid material strongly tempts many researchers. But ionic liquids are usually applied in chemistry and rarely applied in physics. In fact ionic liquids are good photoelectric medium material owing to its well ionic conductivity, transparence. However, in applications, the drive of ionic liquids is the key technic and is also a bottle-neck. Here a kind of electromagnetic drive way is presented, There are not any mechanical moving elements and the drive is bidirectional. Theory and experiments indicate the drive pressure and flow rate are distinct undering a few voltages and 0.5T magnetic flux density. So this drive way can be used as a low power liquid pump. Latency applications in Microfluidics, Optoelectronics and industry are given.

Ionic Dissociation

The clarification of the degree of ionic dissociation occurring in liquid-electrolyte systems such as those used in current lithium-ion batteries is important from both, fundamental and application points of views. In the present study, based on the bond strength–coordination number fluctuation (BSCNF) model proposed by the authors, we consider the relation between the ionic diffusion and dissociation in room-temperature ionic liquids. Specifically, we show firstly, that the molar conductivity Λ is well correlated with the degree of molecular cooperativity NB defined by the BSCNF model. This correlation enables to connect the cooperativity with the degree of ionic dissociation in ionic liquids. Through the comparison between the ionic diffusion coefficients and the molar conductivity, we discuss on a possible relation between these quantities.
