Scientific Trends

Today XAS research is so widely distributed and still is growing in diversity which is a right word to describe recent activities that span from biology to condensed matter, from chemistry to nanoscience. Accordingly XAFS Conferences cover such a wide areas of science and it is difficult to categorize presentations. However, it would be worthwhile to see a recent trend from temporary categories. Here categories for XAFS11 (Akoh, 2000) and XAFS14 (Camerino, 2009) are compared. For simplicity two conferences are compared in categories given below.

  • Molecules & Clusters
  • Inorganic and Organic Chemistry
  • Surface
  • Interface and Nano-structures
  • Amorphous, Glass and Liquids
  • Magnetic Materials
  • Materials for Electronics
  • Environmental
  • Biological Systems
  • Catalysts
  • Experimental Techniques
  • Data Analysis, Related Phenomena
  • Dichroism
  • Theory and Fundamentals
  • Strongly Correlated Materials, Novel Functional Materials
  • Time-resolved, Fast Dynamics
  • Radioactive Materials

The original categories (a-n) are based on K. Baberschke's review on the XAFS conference (J. Synchrotron Rad. 8, 1012 (2001)). Reflecting the recent trend, Strongly Correlated Materials, Novel Functional Materials (o), Time-resolved, Fast Dynamics (p) and Radioactive Materials (q) were added (H. Oyanagi, Sep. 1, 2009).

By comparing the categories for XAFS11 and XAFS14, one would find an obvious trend that all categories are growing in number and distributions are more averaged out, indicating that all fields are growing which explains why XAFS conferences are always successful. Moreover, topics such as strongly correlated materials such as high temperature superconductors and manganites, novel materials such as iron oxynictides, time resolved studies and studies on dynamics, and radioactive materials newly joined to the family. Detailed report on the latest conference (XAFS14, 2009) will be found at the conference web but it is obvious that the XAS community is growing steadily.
