Novel Approaches to Soft X-Ray Spectroscopy:  Scanning Transmission X-Ray Microscopy and Ambient-Pressure X-Ray Photoelectron Spectroscopy

Morning Session

The morning session will highlight areas of new development using scanning transmission x-ray microscopy (STXM). The current state of the STXM’s will be presented with an emphasis on new developments including time-resolved magnetic experiments, electrochemical experiments, as well as environmental science at low energies. The workshop is designed to bring together experts in a diverse range of fields employing STXM for research. The emphasis is on new and novel uses of the STXM and will provide a unique opportunity to exchange ideas and technology.

Afternoon Session

The properties of solid or liquid interfaces in contact with a gaseous environment are of great importance in the fields of environmental and atmospheric chemistry and heterogeneous catalysis.  One of the main challenges is the study of the interaction of water vapor with surfaces.  The high vapor pressure of water at ambient temperatures (4.6 Torr at 273 K) makes the application of many classical surface science techniques difficult or even impossible.  Ambient pressure photoemission spectroscopy (AP-PES) is a promising tool for the investigation of solid/vapor and liquid/vapor interfaces.  Initially developed more than 30 years ago by Hans Siegbahn and coworkers, a growing number of laboratory- and synchrotron-based AP-PES instruments are now being commissioned.  In this workshop we will discuss technical aspects as well as the applications of AP-PES to heterogeneous catalysis and environmental and atmospheric science studies.
