  "abstract": "Polyamide membranes are central to industrial separations, including desalination and water treatment. They are typically described as comprising crosslinked and linear units. Molecular dynamics simulations and topological analysis find branched units to be similar to or more prevalent than crosslinked units, and ignoring them can mischaracterize polyamide membranes. 2 Crosslinked polyamide membranes are widely used as selective layers in thin film composites (TFC) for reverse osmosis, forward osmosis, and nanofiltration.1 The most common desalination membranes are formed by reacting m-phenylenediamine (MPD) with trimesoyl chloride (TMC);",
