The new IZA Ambassador is Paul Ratnasamy.
As the winner of the IZA Award at the last IZC for his outstanding lifetime contributions to and achievements in the field of zeolite science, Prof. Ratnasamy was awarded not only a plaque, but also a travel grant to enable him to give a series of lecture tours during the coming three years. He has put together the following list of potential topics for these lectures:

Denise Bartomeuf

It is with great sadness that we report the death of Denise Barthomeuf on the first of November 2004. Denise served as Vice President of the IZA and chaired the Breck Award selection committee during the period 1986-1989. She also founded the French Zeolite Association (Groupe Français des Zéolithes) in 1986. Her work in the fields of zeolite modification and acid-base catalysis are without doubt major contributions to our scientific community. In addition to her scientific achievements we will cherish the memory of her personal qualities of kindness, generosity and loyal friendship.

George Kokotailo

It is with great sadness that we report the death of George Kokotailo on October 27, 2004. For 34 years, George was a productive materials science researcher with the Mobil Oil Company, Paulsboro, NJ, and for much of this time taught physics in the evenings at Drexel University. His main research interest was in zeolite structure, and he is probably best known for his part in the solution of the structure of ZSM-5. He served as a member of the IZA Council from 1983 to 1989 and from 1992 to 1996, and was a consultant to the original Structure Commission of the IZA. During his career, he received several honors, including the prestigious Alexander von Humbolt Fellowship. His enthusiasm for his work and his generosity to generations of students will be sorely missed by all those who had the privilege of knowing him.
