SUMMARY:PSI Seminar: Oxide Interfaces: Playing away from UHV

DESCRIPTION:Join us for this PSI seminar with guest speaker Dr Rob Lindsa
 y. Preparing and/or probing metal oxide interfaces away from ultra-high 
 vacuum (UHV) can be hugely challenging but is of immense importance for 
 elucidating properties of technological relevance.  In this presentation
 \, Dr. Lindsay will outline some of the endeavours of my group and colla
 borators to contribute to this area.  Firstly\, work conducted on wet-ch
 emically prepared single crystal metal oxide surfaces will be described\
 , focusing on structure determinations of rutile-TiO2(110) and rutile-Ti
 O2(011) with surface X-ray diffraction (SXRD).  It will be demonstrated 
 that non-UHV surface preparation can lead to significantly different sur
 face terminations.  The potential importance of these results will be di
 scussed\, including enhancing our understanding of the superhydrophilici
 ty and photocatalytic activity of titania interfaces.\n\nIn the second p
 art of the presentation\, Dr. Lindsay will describe measurements to unde
 rstand the occurrence of atmopheric corroson prior to surface condensati
 on of bulk liquid water\, i.e.\, at a relative humidity (RH) below 100%.
   The focus will be on the interaction between water vapour (0% ? RH ? 1
 00%) and an oxidised surface of polycrystalline zinc\; the latter is an 
 important material for atmospheric corrosion control.  New light is shed
  onto the phenomenon of atmospheric corrosion through the application of
  two in situ surface spectroscopies\, namely near ambient pressure X-ray
  photoelectron spectroscopy (NAP-XPS) and vibrational sum frequency spec
 troscopy (VSFS).  Combining evidence emerging from both spectroscopies\,
  we conclude that water does not simply grow atop a sharply terminated z
 inc substrate\, as often proposed\, but accumulates through capillary co
 ndensation in the ubiquitous layer of adventitious carbon covering the s
 urface. \n\n\n\n\n\n\n
