DESCRIPTION:Speakers: Hitoshi Abe (Photon Factory (PF)\, Institute of Mate
 rials Structure Science (IMSS)\, High Energy Accelerator Research Organiza
 tion (KEK))\nInstitute of Materials Structure Science is one of the instit
 utes in KEK\, and runs a synchrotron facility\, Photon Factory (PF)\, wher
 e two synchrotron rings\, PF and PF-AR (Advanced Ring) are operated.  PF i
 s operated with the beam energy of 2.5 GeV\, and PF-AR with 6.5 GeV or 5. 
 0GeV to provide higher x-ray energy.  There are about 50 end stations incl
 uding 6 x-ray absorption fine structure (XAFS) beamlines: 9A\, 9C\, 12C\, 
 15A1\, AR-NW2A and AR-NW10A.\n   XAFS is one of the most demanded methods 
 at synchrotrons and is used to study various materials such as catalysts\,
  batteries\, functional oxides\, semiconductors\, minerals and environment
 al samples.  XAFS is usually divided into characteristic two regions\, x-r
 ay absorption near edge structure (XANES) and extended x-ray absorption fi
 ne structure (EXAFS).  XANES is the region of the spectrum from just below
  the absorption edge to ~50-70 eV above the edge.  EXAFS is the other high
 er energy region above XANES and analysed to investigate local structures 
 of elements of interest\, e.g. bond length and coordination number.  We wi
 ll share recent topics of our XAFS studies performed at our facility.  In 
 addition\, I would suggest potential topics to be studied at the AfLS in t
 he context of natural resources in the African continent.\n\nhttps://event
