​Graphene-oxide aerogel helps extract drinking water from air 

An international scientific collaboration, led by the Australian Research Council Centre of Excellence for Carbon Science and Innovation (ARC COE-CSI) UNSW Associate Professor Rakesh Joshi and Nobel Laureate Professor Sir Kostya Novoselov at the National University of Singapore (NUS), has developed a lightweight, sponge-like aerogel made from calcium-intercalated graphene oxide. 

The nanomaterial can hold more than three times its weight in water and can achieve this far quicker than existing commercial technologies, features that enable its potential in direct applications for producing potable water from the air.
