New mechanisms discovered to separate air

(Shinshu University) Unlike the windows of your house, nanoscale holes in graphene (named as 'nanowindows') can selectively choose which type of air molecules can pass through.Scientists from Shinshu University and PSL University, France, theoretically proved concerted motion of the nanowindow-rim to selectively allow molecules to pass, in an energy-efficiently and fast way. This brings up new possibilities to create an advanced molecular separation membrane technology.
