Welcome to the Epsztein Lab!
Who are we?
We are a research group led by Dr. Razi Epsztein at the Faculty of Civil and Environmental Engineering at the Technion. We aim to develop selective separation technologies for a wide range of environmental applications, with a focus on membrane technologies at the water-energy nexus.
Why is selectivity important?
Membrane technology is doing pretty well in water purification and desalination where ideally ALL solutes are UNselectively separated from water. But what if we want to remove a specific pollutant from drinking water and keep the good minerals in the water? Or recover a valuable element from a mixture of species? These examples and many others require membranes that can discriminate between different species. But besides the necessity for selectivity, we find this area of research super interesting!!!
How do we create selectivity?
That’s a great question and the reason why we are here: to figure it out! To do this, we need first to understand the molecular mechanisms that enable selectivity between different species and then develop robust membranes that selectively separate desired species using these mechanisms. Based on this strategy, the research in our lab is divided into three main avenues as illustrated on the right.
