<sod>'''The Du Noüy–Padday method''' is a minimized version of the Du Noüy method replacing the large platinum ring with a thin rod that is used to measure equilibrium surface tension or dynamic surface tension at an air–liquid interface. In this method, the rod is oriented perpendicular to the interface, and the force exerted on it is measured. Based on the work of Padday,<ref name="Padday">Padday, J. F., Pitt, A. R., Pashley, R. M.,1974, "Menisci at a free liquid surface: surface tension from the maximum pull on a rod",J. Chem. Soc., Far. Trans. I, 71(10), 1919–1931 (1974)</ref> this method finds wide use in the preparation and monitoring of [[Langmuir–Blodgett film]]s, ink & coating development, pharmaceutical screening, and academic research.<eod>
