The Patrick Meares Prize

In 2015 the EMS received a donation from the late Patrick Meares, one of the pioneers of membrane science. From his will one can read “...with the request, but without imposing any binding trust, that the sum be used to establish a prize to be awarded biannually to a deserving young membrane scientist on the basis of criteria to be established by agreement between the Board and the Council of the Society.".

With this in mind, the EMS Council established the Patrick Meares Prize for the best Ph.D. thesis work on membrane science.


  • EMS membership (valid membership at least one year before the deadline of applications);
  • D. awarded between 01/07/2018 and 30/06/2021.


  • Two supporting letters (one from outside the applying institution) in which the contribution of the work to the membrane field performed by the applicant is clearly stated;
  • A two pages summary of the thesis contents and a list of published papers and conference presentations based on the thesis work.
  • A proof that the Ph.D. has been awarded (copy of the diploma or certificate of completion from the institution awarding the diploma).

The deadline for applications is 30/06/2021. The applications will be submitted to the EMS Secretariat at


A committee of EMS Council members and Honorary Council Members will evaluate the applications and the 4 shortlisted candidates will be invited to present their work in a Patrick Meares Prize Symposium that will be held at the Euromembrane 2021 congress in Copenhagen (September 12-16). A panel will evaluate the presentations and nominate the winner of the prize at Euromembrane 2021.

The 4 shortlisted candidates will receive a free Euromembrane 2021 registration and the winner of the Patrick Meares Prize wins a check of 1,500 euros.


EMS Logo contest Result



The results for the Logo selection are:

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.

Title: Sustainable Membrane Production through Polyelectrolyte Complexation Induced Aqueous Phase Separation
Presenter: Muhammad Irshad Baig
Affiliation: Membrane Surface Science, University of Twente, The Netherlands
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.
