In memoriam Prof. Yuri Pavlovich Yampolskii


Yuri Pavlovich Yampolskii

08.08.1938 – 24.03.2021


On March 24, 2021, at the age of 83, Professor Yuri Yampolskii, an outstanding scientist, Chief researcher of the TIPS RAS, Doctor of Chemical Sciences, died after a serious illness.

Yuri was at the origin of the Russian membrane science. Since 1973, he worked at the A.V. Topchiev Institute of Petrochemical Synthesis of the Russian Academy of Sciences, where he headed the laboratory of Membrane gas separation.

Yuri Yampolskii was a laureate of the Russian Federation Government Award (1995) for his work in the field of membrane materials science, an honorary member of the European Membrane Society (EMS), a member of the American Chemical Society (ACS), the American Association for Advancing Science (AAAS) and a permanent deputy editor-in-chief of the Petroleum Chemistry journal.

Yuri became world-famous for his work on membrane materials science, in fact, this term, which is widely used today in world science, was coined by him. He was the author of the course of lectures “Membrane Materials Science”, which was taught at the Faculty of Materials Science of MSU since 2004, and continues today by his students. For the first time, he justified the application of the positron annihilation method and other probe methods to the study of the free volume of glassy polymers. His extensive social connections with various groups of scientists in Russia and abroad, including those in the field of synthetic polymer chemistry, allowed us to significantly increase the range of membrane polymers studied and to create in 1998 the Database “Gas separation parameters of glassy polymers”, which is still works as the hallmark of the TIPS RAS Membrane Center. Yuri Yamploskii is the author of more than 450 scientific publications and 12 monographs. His broad scientific outlook and scientific curiosity allowed him to generate new ideas and directions of work until his last days. Thanks to his leadership talent, many of his students work around the world in the field of membrane science and membrane technology.

Bright memory to you, Yuri Yamploskii, colleague, friend and Teacher.

For the first time, I met Yuri Yampolskii in person as a doctoral student at the CHISA 2002 conference held in Prague. Since Yuri was a good friend of my former supervisor Milan Šípek, he also visited our laboratory in all of Prague. Subsequently, we measured the sorption of organic vapors in amorphous Teflon AF2400 for his working group (A. Tokarev et al, Our next personal contact was at the Euromembrane 2006 conference in Giardini Naxos, Sicily. I vividly remember Yuri sitting in a beautiful hotel park on a bench overlooking the sea, and the conference participants coming to the conference building greeted him in a friendly way. Then our meetings were more frequent thanks to the involvement of our workplaces in a solution of joint FP7-NMP DoubleNanoMem project, discussions on joint articles and participation in other conferences such as Euromembrane, ICOM, etc. Our last contact was from last year. As an academic guest editor, Yuri asked me and my close friends from Italy ( ITM-CNR) to review the Ionic Liquid Gas Separation Membranes for Membranes journal.

With Yuri’s passing, the membrane community loses an important member who has been recognized as a scientist and the author of many inspirational books on membrane processes.

Professor Yampolskii contributed with articles, reviews, books and databases to the rationalization and understanding of the process of gas sorption and transport in polymeric membranes for gas separation. He focused, among the others, on fundamental problems such as the ageing of glassy polymers and the role of free volume in gas transport, and created correlations between molecular quantities and separation performance. Professor Yampolskii aimed at creating order in the intricate world of membrane properties and structure. His work will remain to guide those who want to start research in the field of gas separation membranes or want to design a new membrane separation process.
