1 When an interface is formed between an alkane and water, the entropy drops due to reducing the number of configurations that a water molecule can adopt in the hydrogen-bonded network. We calculated that the entropy decrease is about -0.10 mJ/K per m² of surface area to form an interface between the exposed. alkane surface area and water. 1 Use this to estimate -TAS when a peptide amphiphile is moved from the nanofiber into aqueous solution (in kJ/mol at 298K).¶
