Sutapa Ghosal,John C. Hemminger,Hendrik Bluhm,Bongjin Simon Mun,Eleonore L. D. Hebenstreit,Guido Ketteler,D. Frank Ogletree,Félix G. Requejo,Félix G. Requejo,Miquel Salmeron +9 more
TL;DR: Using x-ray photoelectron spectroscopy operating at near ambient pressure, this paper measured the composition of the liquid/vapor interface for deliquesced samples of potassium bromide and potassium iodide.
Journal ArticleDOI
The Nature of Water Nucleation Sites on TiO2(110) Surfaces Revealed by Ambient Pressure X-ray Photoelectron Spectroscopy
Guido Ketteler,Susumu Yamamoto,Hendrik Bluhm,Klas Andersson,David E. Starr,D. Frank Ogletree,Hirohito Ogasawara,Anders Nilsson,Miquel Salmeron +8 more
TL;DR: In this paper, the adsorption enthalpy of water binding to these sites is estimated to be approximately 70 kJ/mol, much stronger than that in the bulk liquid.

TL;DR: In this paper, the application of synchrotron-based spectroscopies and microscopies to environmentally relevant samples is presented. But the experiments were performed at the molecular environmental science beamline (11.0.2) at the Advanced Light Source, Lawrence Berkeley National Laboratory.

In-situ X-ray photoelectron spectroscopy studies of water on metals and oxides at ambient conditions
Susumu Yamamoto,Hendrik Bluhm,Klas Andersson,Klas Andersson,Guido Ketteler,Hirohito Ogasawara,Miquel Salmeron,Miquel Salmeron,Anders Nilsson,Anders Nilsson +9 more
TL;DR: In this paper, the basic design of the ambient pressure X-ray photoelectron spectroscopy setup that combines differential pumping with an electrostatic focusing is described, and examples of the application of in-situ XPS to studies of water adsorption on the surface of metals and oxides including Cu(110), Cu(111), TiO2(110) under environmental conditions of water vapor pressure.
