Researchers develop new graphene nanochannel water
filters

When sheets of two-dimensional nanomaterials like
graphene are stacked on top of each other, tiny gaps form between
the sheets that have a wide variety of potential uses. In research
published in the journal Nature Communications, a team of Brown
University researchers has found a way to orient those gaps, called
nanochannels, in a way that makes them more useful for filtering
water and other liquids of nanoscale contaminants.
