graphene membrane
A new nano-membrane from the "wonder material" graphene is extremely lightweight and breathable. Not only a new generation of functional rainwear, but also ultra-rapid filtration could thus be possible. The membrane that researchers at the ETH Zurich and Empa just presented in "Science" is as thin as it is technically only goes. wwws.empa.ch/plugin/template/empa/3/146762/---/l=1
