Ionic Liquids as Grease Base Liquids

The rheological characteristics of one mineral oil and two ionic liquid (IL) based lubricating greases were explored as a function of thickener concentration. The ILs used are 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([BMIM][TFSI]) and trihexyltetradecylphosphonium bis(trifluoromethylsulfonyl)imide ([P6,6,6,14][TFSI]), with polytetrafluoroethylene (PTFE) particles used as t...

Fractal Liquids

We introduce fractal liquids by generalizing classical liquids of integer dimensions d = 1, 2, 3 to a fractal dimension df . The particles composing the liquid are fractal objects and their configuration space is also fractal, with the same non-integer dimension. Realizations of our generic model system include microphase separated binary liquids in porous media, and highly branched liquid drop...

What atomic liquids can teach us about quark liquids

Over the last ten years there has been truly remarkable progress in the study of cold, dilute gases of fermionic atoms in which the scattering length a of the atoms can be controlled experimentally. These systems can be realized in the laboratory using Feshbach resonances, see1) for a review. A small negative scattering length corresponds to a weak attractive interaction between the atoms. This...

Ionic liquids in tribology.

Current research on room-temperature ionic liquids as lubricants is described. Ionic liquids possess excellent properties such as non-volatility, non-flammability, and thermo-oxidative stability. The potential use of ionic liquids as lubricants was first proposed in 2001 and approximately 70 articles pertaining to fundamental research on ionic liquids have been published through May 2009. A lar...
