DESCRIPTION:Until recently it has not been possible to study liquid surfac
 es with vacuum based surface science techniques\, because they just evapor
 ate and disappear.  However\, ionic liquids are precisely what they sound 
 like\, liquids composed entirely of ions\, where the Coulombic attraction 
 between the ions confers such a high enthalpy of vaporisation that they ca
 n exist as liquids at ultra-high vacuum. So these liquids can now be studi
 ed by the vast range of surface science techniques developed over the past
  half century\, giving molecular level insights into their nature and beha
 viour. I will describe some of our work on the interaction of ionic liquid
 s with gold and copper single crystals\, and the behaviour of gases dissol
 ved in ionic liquids.  Although ionic liquids may appear exotic\, they out
 number the ≈ 600 "normal" liquids by at least 100\,000×\, and with thei
 r chemically tuneable properties\, they are finding ever-increasing uses i
 n academic and industrial applications.
