Clean water with crystals

Cara Doherty is developing new technologies that could transform water filters, batteries and medical sensors, and clean up carbon emissions. And it all comes down to holes and surface area.

She has a vision for a new manufacturing industry for Australia. She works with crystals that are packed with… nothing. They’re highly porous sponges—down to a molecular level—and can be customised to absorb almost any molecule.

These crystals are metal–organic frameworks (MOFs). They can be challenging to make. And it’s also difficult to determine which crystal will be good for which job. But it’s even harder to deploy the crystals—to put them in the right place to do useful work.

Cara uses antimatter (positrons) and synchrotron light (X-rays) to measure the crystals and their properties. Then she uses her patented technique to imprint useful shapes for devices.

With the help of her L’Oréal For Women in Science Fellowship she investigated how to take the next step: to develop the 3D structures that would be needed for a smart water filter.
