22-Apr-25 Database security upgraded  
  Over the last few months, Christian Baerlocher has been working to make the Database of Zeolite Structures CSP (Content Security Policy) compliant, so that users are protected from the possibility of malicious code being injected into the website. A Website Security Test before the CSP implementation showed a grade of C. The current version, on the other hand, has a grade of A.
Thank you, Christian!

The code revision was substantial, and although every effort has been made to make the changes transparent to the user, there may still be a few lingering errors that need to be fixed. If you encounter any problems or strange behavior when using the database, please contact Christian, so that he can correct it.

13-Jun-23 Wilfried J. Mortier (1946-2023)
  It is with great sadness that we must report that Wilfried J. Mortier, who served on the Structure Commission for 33 years (1977-2010), passed away on June 5, 2023 after a long illness. He is best remembered in the Commission for the Herculean effort he put into collecting, organizing and finally publishing the data that are now available in the "Compilation of Extra-Framework Sites in Zeolites". Although the Compilation has not been updated since it was published in 1982 (the amount of work involved would be overwhelming), it continues to be a valuable resource for zeolite scientists. His insistence on correct protocol and precision helped to set the course of the IZA-SC at the very beginning of its existence.

He also served on the IZA Council several times when the IZA was first established and provided similar guidance. During the course of his career, he worked in both academia (KU Leuven) and industry (ExxonMobil), and was happy to share the insight into zeolite chemistry and structure that this brought him.

Those of us who had the privilege of working with him, will always remember him with respect and fondness.
 
16-Feb-23 Database of Zeolite Structures
  The latest release of the php software that is used to access the Database of Zeolite Structures is stricter than the previous versions, and this caused some problems with the website. Christian Baerlocher has now fixed the most obvious failures, but there may still be a few that he hasn't caught. If you notice anything unusual, please contact him.
