Dual-functionalised ionic liquids: synthesis and characterisation of imidazolium salts with a nitrile-functionalised anion

Paul Joseph Dyson, Gabor Laurenczy, Zhaofu Fei, Dongbin Zhao

A series of 'dual-functionalised' ionic liquids, comprising imidazolium cations with various functionalities and the nitrile functionalised anion CH3H(BF3)CH2CN have been prepared; some exhibit very low viscosities-a highly valuable property in many a ...

Mixing Effects for the Structural Relaxation in Binary Hard-Sphere Liquids

Giuseppe Foffi, Francesco Sciortino

We report extensive molecular-dynamics-simulation results for binary mixtures of hard spheres for different size disparities and different mixing percentages, for packing fractions up to 0.605, and over a characteristic time interval spanning up to 5 order ...

Modeling and Analysis of Helicoidal Flow in a Conical Extruder

The present paper discusses the uniqueflow behavior in a new type of extruder. The extruder design is based on a hollow conical assembly of static (stators) and rotating (rotor) parts. Extrusion is achieved from each side of the rotor to provide a two-laye ...

A strong to fragile transition in a model of liquid silica

Philippe Gillet, James Badro

The transport properties of an ionic model for liquid silica [1] at high temperatures and pressure are investigated using molecular dynamics simulations. With increasing pressure, a clear change from "strong" to "fragile" behaviour (according to Angell's c ...

A Study Of Sio2 Glass And Supercooled Liquid To 1950 K Via High-Temperature Raman-Spectroscopy

Philippe Gillet

We have measured in situ Raman spectra of SiO2 glass between room temperature through the glass transformation range to the supercooled liquid at 1950 K, using a new wire loop heating technique. These results provide valuable insights into the structural a ...
