Separation Science: a theoretical, experimental and industrial union
28-30 June 2023
Organizers: Ian Griffiths (Oxford), Guy Ramon (Technion) & Uwe Beuscher (W.L. Gore & Associates)
Objectives
Recent years have seen a surge in the number of applications utilizing membranes, from large-scale separations in the chemical, pharmaceutical and water sectors, to biomedical devices and sensors. While many of the early advances have been made by empirical and experimentally driven approaches, mathematical modeling and simulation have started to become more commonplace in the membrane field for supporting experimentation, interpretation of results, and exploring mechanistic hypotheses.
With the growing number of applications and the need for tailored membrane properties and separation capabilities, mathematical and physical modeling and prediction of material properties, energy efficiency, and environmental sustainability is driving a growing interest in developing better quantitative membrane models on a material, membrane, and process scale.
The goal for this workshop is to bring together researchers with expertise in membrane science and related fields at the various length scales to build a community for modeling membrane properties, membrane transport, and membrane processes. We are envisioning this as the first in a series of workshops for developing state of the art models for the advancement of membrane science and technology.
Venue, accommodation and travel
- The venue of the workshop is The University of Oxford's Mathematical Institute.
You can find out more about travelling to the Mathematical Institute here.
The workshop will take place in lecture theatre L4, which is located on the mezzanine level of the Mathematical Institute.
Classroom C1 is also available for breakout discussions, and is also located on the mezzanine level.
