Ionic-liquid materials for the electrochemical challenges of the future.
TLDR
The goal in this review is to survey the recent key developments and issues within ionic-liquid research in these areas, and to generate interest in the wider community and encourage others to make use of ionic liquids in tackling scientific challenges.Abstract:
Ionic liquids are room-temperature molten salts, composed mostly of organic ions that may undergo almost unlimited structural variations. This review covers the newest aspects of ionic liquids in applications where their ion conductivity is exploited; as electrochemical solvents for metal/semiconductor electrodeposition, and as batteries and fuel cells where conventional media, organic solvents (in batteries) or water (in polymer-electrolyte-membrane fuel cells), fail. Biology and biomimetic processes in ionic liquids are also discussed. In these decidedly different materials, some enzymes show activity that is not exhibited in more traditional systems, creating huge potential for bioinspired catalysis and biofuel cells. Our goal in this review is to survey the recent key developments and issues within ionic-liquid research in these areas. As well as informing materials scientists, we hope to generate interest in the wider community and encourage others to make use of ionic liquids in tackling scientific challenges.read more

Toxic effects of imidazolium-based ionic liquids on Caenorhabditis elegans: The role of reactive oxygen species
TL;DR: The results suggest that ROS play an important role in IL-induced toxicity in Caenorhabditis elegans, and the addition of 0.5% dimethyl sulfoxide, which acts as a radical scavenger, remarkably rescued the lethality of C. elegans and significantly decreased the ROS level.

Pyrrolidinium-Based Ionic Liquids Doped with Lithium Salts: How Does Li+ Coordination Affect Its Diffusivity?
Franca Castiglione,Antonino Famulari,Guido Raos,Stefano Valdo Meille,Andrea Mele,Giovanni Battista Appetecchi,Stefano Passerini +6 more
TL;DR: The long-range, intermolecular NOEs have been detected and provide information on the ions' organization beyond the first solvation sphere and the minimum energy structures for all systems correspond to a tetrahedral coordination of the Li-ion by four oxygen atoms of the anions.
