A better way to provide clean drinking water

post-image

In a revolutionary breakthrough, a team of researchers have come up with a method to turn sea water into safe drinking water in a way that's more energy efficient, economically sustainable and cost effective than current technologies. Metal-Organic Frameworks (MOFs) are an amazing next generation material that have the largest internal surface area of any known substance. The sponge like crystals can be used to capture, store and release chemical compounds. In this case, the salt in sea water.

A just released paper found that membranes made out of MOFs can mimic the way cells allow specific atoms or molecules through to help them grow and survive, while stopping everything else. Known as selective permeability this allows cells and now MOFs to act as a filter. MOF's selective permeability means they're designed at the molecular level to only let water pass. https://blog.csiro.au/ocean-glass-sucking-salt-sea/
