Manchester Scientist Develops Designer Membranes

A new graphene project will revolutionise current desalination methods - filtration will need less energy and will not clog. 

Sebastian Leaper, a PhD student at the University of Manchester, is the winner of the Eli and Britt Harari Graphene Enterprise Award 2016.

The £50,000 award which is now in its third year aims to encourage the development of new graphene enterprises from budding entrepreneurs across the University’s undergraduate, postgraduate and post-doctoral researcher communities, as well as recently graduated alumni of the University.

The prize money will help fund a new graphene project, which has the potential to revolutionise current desalination methods which are currently costly in terms of energy usage and the need for pre-treatment.

Using a graphene membrane in the desalination process can help improve the process and fine-tuning its properties can overcome some of the challenges associated with desalination as it can allow water to permeate through them with hardly any resistance.

This uses less energy and is not susceptible to clogging. Untreated water can also be used in the membrane, making it low maintenance. 

This technology has the potential to revolutionise water filtration across the world, in particular in countries which cannot afford large-scale desalination plants.

This system can be built on smaller scales and is flexible making this technology accessible to countries which do not have the financial infrastructure to fund large plants without compromising the yield of fresh water produced.

Sebastian (23), who is currently undertaking his PhD within the Graphene NOWNANO Centre for Doctoral Training said: “When you live in Manchester, it's easy to forget that there's a global water shortage going on. It's crazy to think that in the 21st Century, there are still people who have to walk miles every day for such a basic commodity. Graphene has promise to unlock the door to low-cost, sustainable desalination technology that can end the global water crisis.”

The award is co-funded by the North American Foundation for The University of Manchester through the support of one of the University’s former physics students Dr Eli Harari (founder of SanDisk) and his wife Britt. It recognises the role that high-level, flexible early-stage financial support can play in the successful development of a business targeting the full commercialisation of a product or technology related to research in graphene.
