Temperature-dependent electronic and vibrational structure of the 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide room-temperature ionic liquid surface: A study with XPS, UPS, MIES and HREELS
Article Abstract:
A study to determine the near-surface structure of the room-temperature ionic liquid 1-ethyl-3-methylimidazolium bis) trifluoromethylsulfonyl) amide as a function of temperature in the range 100 to 620 K is conducted. Results showed that molecules at the surface-vacuum interface are not randomly oriented at low temperatures and volatilization of [EMIM][[Tf.sub.2]N] begins at around 350K.

Interaction of NaI with solid water and methanol
Article Abstract:
The interaction of NaI with amorphous solid water (ASW) and methanol (MeOH) is investigated with metastable impact electron spectroscopy (MIES), UPS(HeI), and temperature programmed desorption (TPD). Surface segregation of iodide is observed in ASW, as predicted for NaI aqueous solutions, but it is not observed in MeOH, as predicted for the interaction of NaI with liquid methanol.

Interaction of CsF with multilayered water
Article Abstract:
Metastable impact electron spectroscopy (MIES) and ultraviolet photoelectron spectroscopy with HeI (UPS(HeI)) is used to investigate the interaction of CsF with multilayered water. CsF-H2O interfaces are prepared on tungsten substrates at 80 and 120 K, namely, CsF layers on multilayered water and H2O adlayers on thin CsF films.
