14-Sep-19 Jens Weitkamp (1942 - 2019)

Professor Dr.-Ing. Jens Weitkamp, the former director of the Institute of Chemical Technology of the University of Stuttgart passed away in Paris on August 25, 2019, the same town in which he was born on June 5, 1942. Jens Weitkamp studied chemistry at the Universities of Berlin and Karlsruhe. In 1971 he completed his doctoral studies under the supervision of Professor Dr. H. Pichler and his habilitation a few years later at the Engler-Bunte Institute of the University of Karlsruhe with Prof. Dr. K. Hedden. In 1986, Jens Weitkamp became Professor of Chemical Technology at the University of Oldenburg. In 1988 he took over a Full Professor position for Chemical Technology at the University of Stuttgart.   
High quality research on upgrading of crude oil and natural gas as well as petrochemistry has determined the scientific life of Jens Weitkamp and he has advanced these fields to a very large extent. Examples are refinery processes like cracking, hydrocracking, isomerisation, alkylation, reforming and demetallization as well as petrochemical reactions like alkylation of aromatics, transalkylation and epoxidation. Jens Weitkamp has advanced our understanding of zeolites and porous materials significantly.                                                     
In his service to the International Zeolite Association, he served on the IZA council from 1994 till 2001 acting as the vice-president from 1994 to 1997 and the president from 1997 to 2001. He also served as the Chairman of the 10th International Zeolite Conference (IZC), held in Garmisch-Partenkirchen in 1994. In 1993, Jens Weitkamp founded the scientific journal “Microporous Materials”, which he edited until the merger with “Zeolites” in 1997. From 1998 to 2003 he edited the new scientific journal “Microporous and Mesoporous Materials” as Editor-in- Chief, which became the leading journal within the field of zeolites and porous materials.                            
Jens Weitkamp received a number of highly ranked recognitions among them are the Alwin-Mittasch-Prize of the DECHEMA (2010) and the Carl-Engler Medal (2002) of the German Society for Petroleum and Coal Science and Technology (DGMK). He became Corresponding Member of the Saxon Academy of Sciences and Humanities in 2003.                                                                                                                                                   
The scientific community devoted to the research of zeolites, porous materials and heterogeneous catalysis shows great respect for the lifetime achievement of Jens Weitkamp and we regret the loss of this excellent scientist, teacher and human being. We will keep him in our memories. Our thoughts go to Sophie, his companion for the last ten years.

20-Jun-19Alberto Alberti (1938 - 2019)
Alberto Alberti suddenly passed away on June 7th, 2019, two days from his 81st birthday. Alberto has been a major pillar of the community of natural zeolites and of crystallography of zeolites. Called by Glauco Gottardi to the Institute of Mineralogy of the University of Modena in 1966, he was an early developer of modern treatment of crystallographic data. He moved in 1986 to the University of Sassari and in 1989 to the University of Ferrara, where he started a successful school of crystallography.                     
In the field of natural zeolites, his name is connected to the discovery and structural refinement of a number of new minerals, from barrerite to gottardiite, terranovaite and mutinaite. Throughout his career, he built bridges between the communities of natural and synthetic zeolites, showing the structural identity of many synthetic zeolites and their natural analogs. He brought fundamental contributions to the crystallochemistry of zeolites, shedding new light on the mechanisms of reconstructive phase transitions and of mobility of cations and acidic protons, improving the understanding of the properties of zeolites and aluminophosphates.              
His dedication to the zeolite community motivated his active participation to the instances of the International Zeolite Association, the International Mineralogical Association and the Associazione Italiana Zeoliti. The number of students who have been induced by his example to endeavour careers in research and teaching is the best witness of his capacity of transmitting his passionate love for science. The colleagues and students of Alberto will fondly remember his kindness, his human warmth and his commitment to help alleviating any human suffering.

6-Mar-19News from the Italian Zeolite Association
The AIZ-CIS-GIC Joint Meeting 2019 will honor the great Italian Scientist, Dr. Giuseppe Bellussi (Senior Vice President R&D Energy Transition Program in the Development, Operations & Technology division of the Eni Company) for his outstanding contribution to the  Zeolite Science and Technology.

1-Mar-19New reports from the Natural Zeolite Commission
Two new reports concerning the sedimentary zeolite deposits in Bulgaria and in Jordan have been put online in the Natural Zeolite Commission website.

7-Feb-19Harry Edwin Robson (1927 - 2019)
It is with great sadness that we must report that Dr. Robson, a former employee of Exxon and renowned expert in zeolite synthesis, passed away on January 18, 2019.
Harry Edwin Robson was born on 19, 1927 near Burlington, USA. He earned a Ph.D. in Physical Chemistry in Kansas University. He moved to Baton Rouge in 1957 to join the research lab at Esso (later Exxon), remaining there until his first retirement in 1986. He spent the next six years consulting in the chemical industry and teaching at LSU. He was a pioneer in the field of zeolite synthesis, and he was instrumental in the formation of the International Zeolite Association. With his colleagues, he compiled and edited three books on zeolite synthesis.
The zeolite community and in particular the synthetic chemists will continue to enjoy his  legacy for many years to come.

4-Feb-19Stefan Ernst (1960 - 2019)
It is with great sadness that we report the passing of Professor Stefan Ernst. This is truly a loss for the worldwide community of chemical technology and zeolite science in particular. Stefan Ernst studied Chemical Engineering in Karlsruhe, obtained his Ph.D. in Oldenburg with Jens Weitkamp and finished his habilitation at the University of Stuttgart.  Since 1997, he has been Professor of Chemical Technology at TU Kaiserslautern.
Stefan Ernst is known as one of the pioneers of zeolite science in Germany. He has made outstanding contributions to the synthesis of zeolites and their application in industrial catalysis. A landmark example is the synthesis of phase-pure ZSM-20 in 1987. Moreover, he introduced the spaciousness index to characterize the effective pore width of bifunctional zeolites via a catalytic test reaction. Stefan published more than 150 papers in particular on zeolite-based ship in the bottle catalysts as well as hydrocarbon isomerization and cracking. He established ethylbenzene disproportionation as a standard reaction for the characterization of acid zeolites.
Moreover, Stefan was closely connected with scientific organizations such as DECHEMA, the German Zeolite Association and the German Catalysis Society. He served on the board of the International Zeolite Association (IZA) und was chair of its catalysis commission. He organized and contributed to many national and international conferences in the fields of zeolites and petrochemistry.
Whenever we met him, we could feel his passion for zeolites and catalysis. His large profound knowledge and friendly encouragement made him a well-respected advisor for students, co-workers, colleagues and industrial partners. We will certainly memorize his ability of networking and connecting people across regions, cultures, faculties and generations. His unselfishness, kindness, strong support and knowledgeable advice will surely be missed by the zeolite community.

25-Aug-17Gérard Férey (1941 - 2017)

It is with great sadness that we report the passing of Professor Gérard Férey, one of the pioneers of metal-organic framework chemistry.

Gérard was born in Normandy in 1941 and began his scientific career at the University of Le Mans in the 1960s. Initially, he was a solid-state fluorine chemist but his interest in microporous materials began with his work on fluorophosphate open framework solids and his synthesis if the ULM-n series of compounds, and his pioneering Secondary Building Unit (SBU) approach of crystalline porous solids. In 1996 he moved to the University of Versailles Saint-Quentin-en-Yvelines and founded the Institute Lavoisier de Versailles. It was here that he began his work on metal-organic frameworks (MOFs) and his laboratory produced some of the most iconic MOFs including the flexible MIL-53 and MIL-88, and highly porous frameworks such as MIL-100 and MIL-101. Throughout the latter part of his career he was a strong supporter of the zeolite and MOF communities, and in particular his efforts to ensure that MOFs became recognised by the IZA. 

Gérard received many awards during his long career; he was awarded France’s highest scientific honour, the gold medal of the CNRS in 2010, and was inducted into the Ordre National de la Légion d'honneur – France’s highest civil award. Gérard Férey’s legacy and his commitment to the community will be felt by all followers of microporous materials for many years to come.

17-Mar-16 Jule Rabo (1924-2016)

It is with great sadness that we must report that Jule Rabo, one of the pioneers of zeolite science, passed away on March 1, 2016.

Dr. Rabo, one of UOP's leading scientists, has a long list of accomplishments, but he is best known for his discovery of the acidic forms of zeolite Y and and for applying them to petroleum catalysis. The catalysts he discovered have formed the basis for the production of motor fuels for almost 60 years. He was a Senior Research Fellow at Union Carbide, later UOP, and continued to consult for the company for many years after his retirement in 1990.

He earned wide recognition for his discoveries, and received numerous awards, including, in 1993, the Chemical Pioneer Award from the American Institute of Chemists for pioneering discoveries in zeolite catalysis. He was a generous teacher who shared his knowledge enthusiastically with colleagues and students during his career. He lectured widely on catalysis and surface chemistry at national and international conferences, at universities, catalysis societies and industrial research centers all over the world. He earned more than 60 U.S. patents and authored several dozen articles, studies and books. The zeolite community will continue to enjoy this legacy for many years to come.
