The Hitchcock group develops new instruments, methods and applications
of inner shell excitation spectroscopies and microscopies for analysis
of advanced materials. We are particularly active in the application of
X-ray microscopy to fuel cell materials, polymers, nanostructures,
biomaterials, magnetotactic bacteria, environmental studies. A focus at
present is in situ and operando methods, such as in situ
flow electrochemistry, investigation of polymer electrolyte membrane fuel
cell electrodes under realistic (T,RH), and studies of peptide - model
lipid membrane interactions. We also continue using electron impact and
synchrotron methods to advance our understanding ot the fundamentals of
Inner shell excitation spectroscopy of gases, surfaces, solids and
Our group has helped develop the most advanced analytical soft X-ray microscope in the world (a scanning transmission X-ray microscope at the Advanced Light Source in Berkeley, and lead the mplementation of STXMs at the Canadian Light Source (CLS) in Saskatoon). We are exploring new applications on a monthly basis. Over the past 5 years, in collaboration with instrument developers and scientists at the CLS, we have helped develop a new cryo-STXM with capabilities for cryo-spectro-tomography. We are helping to develop analysissoftware and applications of soft X-ray ptychography.
The CLS soft X-ray spectroscopy beamline (SM) features two scanning transmission X-ray microscopes (STXM) and an X-ray photoemission electron microscope (X-PEEM) on separate branch lines of a high performance plane grating monochromator beamline, illuminated by an elliptically polarized undulator.
Please explore the pages of this web site. It contains highlights of our research, information about group members, opportunities for research positions, a list our publications (with links to pdfs), and links to tools we provide to others - aXis2000, BAN, the Core Excitation Bibiography and Database (~600 spectra of ~400 gas phase compounds!!), and a X-ray microscopy bibliography as well as links to related sites.
