 k\, McMaster University\, Hamilton (Ontario)\, Canada\n\nTitle: Chemically
  sensitive imaging with synchrotron based soft X-ray STXM and ptychography
 \n\nRegistration deadline: Oct 12\, 11:00 CET\n\n\nBIO\n\nAdam Hitchcock 
 was born and educated in Canada (B.Sc.\, Chemistry\, McMaster\, 1974\; Ph.
 D.\, Chemical  Physics\, UBC\, 1978). His research focus is inner shell e
 xcitation spectroscopies and spectromicroscopies. A professor at McMaster 
 since 1979\, his group has studied inner shell electron energy loss (EELS)
  spectroscopy of gases and surfaces\, using home built instruments. In 198
 0 he started synchrotron experiments\, initially hard X-ray spectroscopy o
 f materials at Cornell (USA)\, then soft X-ray spectroscopy of gases at LU
 RE (France) and SRC (USA). In 1994 he began developing soft X-ray transmis
 sion microscopes (STXM) and photoemission microscopes (PEEM) at ALS (USA).
  He helped establish the Canadian Light Source (CLS\, Saskatoon) and the C
 LS spectromicroscopy beamline\, currently equipped with 2 STXMs and a PEEM
 . In 2006\, he was awarded fellowship of the Royal Society of Canada (FRSC
 \, Canada’s highest scientific honor)\, for his contributions to develop
 ment of X-ray microscopy and the CLS.  His current research is focused on
  technique developments of STXM and ptychography and their application  t
 o automotive fuel cell materials\, in situ electrochemistry\, magnetic bac
 teria\, and catalysts for CO2 reduction.\n\nABSTRACT\n\nSoft X-ray scannin
 g transmission microscopy (STXM) is a powerful synchrotron based tool for 
 nanoscale materials analysis. Ptychography (scanning coherent diffraction 
 imaging) which can be measured using soft X-ray STXMs\,  provides signifi
 cant improvements in spatial resolution (~10 nm\, as opposed to 20-30 nm f
 or conventional STXM). Quantitative 3D imaging (tomography) at multiple ph
 oton energies – can be performed with STXM  and ptychography. Principle
 s of STXM and ptychography will be described\, with emphasis on spectromic
 roscopy - X-ray absorption spectroscopy (NEXAFS) and chemical mapping by i
 maging at multiple photon energies. Applications in biosciences (magnetota
 ctic bacteria)\, energy materials (fuel cells\, CO2 reduction catalysts) a
 nd in situ electrochemical studies will be presented.\n\nDuring our events
  we sometimes take photographs and short film clips to profile our activit
 ies. Please let us know if you don’t want to be in any photos/films befo
 re we start the event. Some talks might be recorded to be used for educat
 ional purposes in the LINXS website.\n\nBy registering to our events you g
 ive your permission to LINXS\, according to the General Data Protection Re
 gulation (GDPR)\, to register your name and e-mail address to be used for 
 the sole purpose of distributing newsletters and communications on LINXS a
 ctivities.\n\nhttps://lindico453.srv.lu.se/event/247/
