Effect of Ionic Liquid Electrolytes in DSSCs with Titanium Dioxide (TiO2) Inverse Opal Structures
… and volatilization. We propose that using ionic liquids (ILs), which are more viscous, less volatile, and conductive, may be more suitable electrolytes. However, one unwanted side effect of the higher viscosity of the ILs may be an incomplete infiltration of the DSSC’s nanoporous TiO2 …

Systematic coarse-graining of ionic liquid
… molecular simulation of imidazolium-based ionic liquids (ILs). To obtain CGFF parameters, we employ a systematic coarse-graining approach based on the relative entropy (RE) method to reproduce not only the structure but also the thermodynamic properties of the reference all-atom molecular …

Structure-Activity Relationship and Mitochondrial Actions of Ionic Liquids as Potential Anticancer Agents
Ionic liquids (ILs) are a class of low melting point salts. They possess unique physicochemical properties that make them amenable to many industrial processes, however, their cytotoxicity presents a liability for their commercial utilisation. On the other hand, the cytotoxicity of ILs presents …

Cost Effective Synthesis of Ionic Liquids and Their Thermal Properties
<p>Ionic liquids (ILs) are liquid organic salts at room temperature which are composed of only ions (cations and anions). Ionic liquids are regarded as “novel solvents” and have been gaining attention as alternatives to volatile molecular organic solvents. Ionic liquids have outstanding properties, …

Functionalization of nanoclays through exchange reactions
A cationic clay (sodium-montmorillonite, MMT) and an anionic clay (hydrotalcite, HT) were treated with two phosphonium based ionic liquids (ILs) and a commercial corrosion inhibitor. Clay modification was examined by TGA, FTLR and WXRD. The cationic clay modified with both ILs had similar thermal …

Thermodynamical, structural, and dynamical characterization of solvent mixtures of technological interest: experimental and computational studies
N-methyl-2-pyrrolidone(NMP) and ionic liquids(ILs)are solvents with “green” characteristics, such as low volatility and low toxicity. They can be used as a valid alternative to the common organic solvents with a high environmental, health and safety impact. The aim of my research was to investigate …

Interaction studies of imidazolium based ionic liquids with organic acids and acetophenone : thermodynamic, spectroscopic, and theoretical approaches
Ionic liquids (ILs) are salts that are primarily composed of cations and anions. They exist as liquids below 100°C or at room temperature, which is why they are sometimes referred to as room-temperature ionic liquids (RTILs). These salts are receiving a great deal of attention in a wide range of …
