"fractionation into gasoline, diesel, heating oil accounts for 1% world’s energy use... instead of separating components by boiling points, filters crude oil components by molecular size... resistant to swelling, scalable thin film manufactured using common technique, 90% less energy use... reverse osmosis water desalination polymers modified by changing bond connecting monomers from amide bond to more rigid/ hydrophobic imine bond... also introduced triptycene monomer... high permeance and excellent selectivity"
