Actuation and Charge Transport Modeling of Ionic Liquid-Ionic Polymer Transducers
Ionic polymer transducers (IPTs) are soft sensors and actuators which operate through a coupling of micro-scale chemical, electrical, and mechanical mechanisms. The use of ionic liquid as solvent for an IPT has been shown to dramatically increase transducer lifetime in free-air use, while also …

Ion dissociation and transport behavior in ionic liquids and ionic liquid solutions
The study of ionic liquids (ILs) has increased significantly over the past two decades as their favorable physiochemical properties have allowed them to be applied in a range of separation, electrochemical, and biological processes. During this time, researchers have repeatedly demonstrated the …

Structure and Ionic Conductivity Properties of Ionic Liquid@Metal—Organic Framework Composites
IL@MOF (IL: ionic liquid; MOF: metal-organic framework) materials have been proposed as a candidate for solid-state electrolytes, combining the inherent non-flammability, high ionic conductivity, and high thermal and chemical stability of the ionic liquid with the host-guest interactions of the …

A Novel Use for Ionic Polymer Transducers for Ionic Sensing in Liquid
Ionic electroactive polymers have been developed as mechanical sensors or actuators, taking advantage of the electromechanical coupling of the materials. This research attempts to take advantage of the chemomechanical and chemoelectrical coupling by characterizing the transient response as the …

A computational study of acidic Ionic Liquids for cellobiose hydrolysis in ionic liquids
… acids catalysts (pKa < −3.2). Room temperature ionic liquids (RTILs) provide potentially environmentally friendly alternative. It has been shown that ILs can dissolve cellulose under relatively benign conditions and can possibly be adapted into a one-pot-like process of hydrolysis using …

Rare gas alkali ionic excimers
The rare gas alkali ionic molecules are established as a new class of ionic excimers which emit in the vacuum ultraviolet (VUV) regime of the electromagnetic spectrum. Temporal and spectral characteristics of these species with (XeRb)$\sp{+}$ at 164 nm and (XeCs)$\sp{+}$ at 160 nm have been …

Membrane Drying of Ionic Liquid
<p>Room temperature ionic liquids (RTILs or, simply, ILs) are liquid salts at temperatures near or slightly above room temperature. ILs consist entirely of bulky, asymmetric organic cations and a variety of anions and, as a consequence, ILs have non-measureable vapor pressure. Due to their unique …

Charge Control of Ionic Polymers
Ionomeric polymer metal composites can be used as transducers characterized by high strain and low force. They are created by bonding a thin conductive electrode to the surfaces of an ionomeric polymer. Much of the work in the past has focused on using a voltage across the thickness of the polymer …
