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, https://doi.org/10.1002/polb.20725). 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.

Title: Preparation of Anion Exchange Membranes using recycled membranes as support for water treatment: towards the circular economy approach

Presenter: Amaia Lejarazu-Larrañaga

Affiliation: Membrane Technology research group at IMDEA Water institute (Madrid, Spain)

Abstract: In this webinar, a new methodology for the preparation of Ion Exchange Membranes, using discarded Reverse Osmosis membranes as mechanical support will be presented. These novel membranes have been prepared by casting a polymeric mixture on the pretreated surface of the discarded Reverse Osmosis membrane. The resulting membranes have been tested in desalination by electrodialysis, selective electro-separation, Donnan Dialysis and Ion Exchange Membrane Bioreactor processes. This research could open an alternative within the recycling of discarded Reverse Osmosis membranes, avoiding landfilling and moving membrane technology into a circular economy.

Speaker Short biography: Amaia Lejarazu-Larrañaga is a PhD candidate working in Membrane Technology research group at IMDEA Water institute (Madrid, Spain). Her main research activities are focused on membrane recycling, preparation of ion exchange membranes, membrane characterization and evaluation of membrane performance, selective separation, Electrodialysis, Donnan Dialysis and Ion Exchange Membrane Bioreactor processes.

EMS WEBINAR ANNOUNCEMENT, Feb 3rd 2021

Wednesday February 3rd 4:00 PM (CET)
Title: Sustainable Membrane Production through Polyelectrolyte Complexation Induced Aqueous Phase Separation
Presenter: Muhammad Irshad Baig
Affiliation: Membrane Surface Science, University of Twente, The Netherlands
Abstract
Nonsolvent induced phase separation (NIPS) is the most common approach to produce polymeric membranes. Unfortunately, NIPS relies heavily on aprotic organic solvents like N‐
methyl‐pyrrolidone to produce the membranes. These solvents are unsustainable, repro‐toxic for humans and have therefore been restricted within the European Union [1]. A new and sustainable method, aqueous phase separation (APS), is presented that eliminates the use of organic solvents. Polymeric membranes can be prepared entirely in water using this new APS method. A homogeneous solution of two polyelectrolytes, the strong polyanion poly(sodium 4‐styrenesulfonate) (PSS) and the weak polycation poly(allylamine hydrochloride) (PAH), is prepared at high pH, where PAH is uncharged. Immersing a film of this solution in a low pH bath charges the PAH and results in the formation of a porous, water-insoluble polyelectrolyte complex. The rate of precipitation can be controlled by a number of parameters for instance, polyelectrolyte solution concentration and pH of the bath. The pore sizes can be tuned from micrometers to just a few nanometers, and even to dense films, simply by tuning the
polyelectrolyte concentrations, molecular weights, and the salinity of the bath. This leads to excellent examples of microfiltration, ultrafiltration, and nanofiltration type membranes.
Similarly, using different types of polyelectrolytes it is possible to produce polymeric membranes in mild pH conditions. A mixture of PSS and Polyethyleneimine (PEI) can be cast at pH 4 to obtain dense nanofiltration type membranes with molecular weight cut-off ~200 g·mol–1. Polyelectrolyte complexation induced APS is indeed a viable and sustainable approach to membrane production that provides excellent control over membrane properties and even allows new types of separations.

In memoriam Prof. C.A. (Kees) Smolders

 

The EMS mourns the loss of Professor Kees Smolders, Honorary Member of our Society since 1991, who passed away on 4 January 2021 at the age of 90.

 

Kees Smolders was a true pioneer in the field of Membrane Technology. He worked as a full professor between 1969 and 1991 at the THT (‘Technische Hogeschool Twente’), renamed to UT (University of Twente) in 1986. While he started out as a professor in Colloid and Interface Chemistry, he was one of the first in the Netherlands to focus on a new field: the field of membranes. He was unique in his persuasiveness, making many others, scientists and businesses alike, enthusiastic for a field of science that was very new at the time. He quickly became a leading scientist in this field, especially through his work on understanding phase inversion that still has a high number of citations to this day. Kees Smolders was one of the first professors to co-operate with companies actively: he was, for example, actively involved in the start-up of X-Flow in the eighties, helping the UT to establish itself as the entrepreneurial university that it is today. Kees Smolders supervised nearly 40 PhD students. The research that he started more than 50 years ago is still actively continued at the UT within the current Membrane Science and Technology (MST) cluster.

After his retirement, he picked up painting, using acrylates, and later he also took up bronze sculpting. In 2016, Kees Smolders donated one of his works of art, appropriately named “The Science Ladder”, to the UT, which is still proudly exhibited in one of the University buildings. The sculpture shows a small man climbing up a double DNA helix. Kees Smolders described it in his own words: “It shows how you can grow in science. Scientists always want to climb to the top, to build up the best reputation.”

Professor Kees Smolders will be remembered a visionary scientist and one of the initiators of membrane research in Europe. The EMS whishes his family, friends and the Membrane Science and Technology cluster at the University of Twente all strength to deal with this loss.
