Diffusion Lab predicts room temperature diffusivity of solvent (molecule) within polymers and solvent sorption at different activities.
            
            Use molecular SMILES for solvent and polymer SMILES with [*] symbols for polymer.
            
            
              Activity and solvent density must be positive values. Please provide the solvent density at STP to get reasonable predictions.
