Significant Difference

Electrochemical sensors can detect the heavy metal ions in seawater quickly, conveniently and accurately with the advantages such as the fast detection speed, the simple operability and the low cost. The ionic liquid [Emim]CH3SO3 showed excellent electrochemical performance and could meet the initial application requirements as electrochemical sensors. The characters of the ionic liquids [Emim]CH3SO3 and [Emim]PF6 which include IR, LC-MS, conductivity, electrochemical window and viscosity were detected. The influ-ence of trace impurity on the conductivity of the ionic liquids was investigated. Results suggested that the conductivity of the ionic liquids increased with the concentration of the added organic solvents. In addition, though the conductivity of the ionic liquids increased with temperature, there is no significant difference in the influence of the same impurity at varying temperatures. Muti Walls Carbon Nanotubes (MWCNTs) are appropriate materials which are commonly used materials for electrochemical sensor applications. The effect of theImidaz-olium-based ionic liquids on the performance of the conductivity of the MWCNTs was studied. It was found that Ionic liquid is an excellent extraction agent for metal ions and its presence in the sensor system improves significantly the detection of heavy metal ions.

In this work, different kinds of ionic liquids and reaction conditions for the extraction of lipid from microalgae biomass were optimized and repeated use of ionic liquids for microalgal lipid extraction was evaluated. Morphological changes of microalgae cells were compared in terms of pre- and post-treatment to understand the mechanisms of ionic liquid treatment. Ionic liquid [BMIM][MeSO4] showed the best lipid extraction efficiency at 70°C and with reaction time of 2 hours. The ratios (ILs : methanol) of 1 : 7 and 1 : 3 were the optimum ratios to complete the extraction of the lipids from microalgae. The initial 50% volume fraction of [BMIM][MeSO4] was 16.04% of dry weight, which showed the highest five average extraction rates. The loss of ionic liquid in the reaction system and the increase in water content of ionic liquids were considered as the main reasons for the decrease in the extraction rate. It is suggested that the potential of lipid extraction in this IL-methanol co-solvent system is promising due to the high efficiency, low cost, safety, environmental protection, and other characteristics.

The fascinating properties of ionic liquids make it possible to synthesize semiconductor nanostructures via a simple and low-cost electrochemical pathway. The present paper summarizes our recent work on the synthesis of Si, Ge, and SixGe1–x nanostructures from ionic liquids: thin films, nanowires and photonic crystals. We also introduce our first results on the template-assisted electrodeposition of SixGe1–x photonic crystals from 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide ([EMIm]Tf2N) ionic liquid, and some optical measurements on the previously prepared Ge photonic crystals. Our results confirm that electrochemistry in ionic liquids is excellently suited to the synthesis of high-quality semiconductor nanostructures.

Biodiesel has attracted considerable interest in recent years as an alternative, biodegradable and nonpolluting transportation fuel. Conventional alkaline process for biodiesel production are energy consuming and generate undesirable by-products such as soaps, that make difficult the separation and purification of biodiesel. Ionic liquids as environmentally benign chemical solvent, had been used in diverse chemical reactions. Especially, they could be applied in biodiesel production. Preparation of biodiesel catalyzed by ionic liquids have many merits, such as no corrosion to equipment, no pollution to environment, and reusability. Ionic liquids can improve the catalytic activity and they have wide utilization prospect in biodiesel preparation. In this paper, the advances in the Brønsted ionic liquids catalysts and their application in biodiesel production through esterification of fatty acids were reviewed. In addition, the prospect for the application of the ionic liquids to catalyze biodiesel production was also stated. Since the cost of ionic liquid may be an issue, there are some challenges to be faced, such as the production of ionic liquids with low cost, easy recovery and with the possibility of reutilization of the catalyst for several cycles.
