Figure 6.

Left side: comparison of the difference xSLD profiles determined from the X-ray interferometry experiments for VSD:POPC membrane tethered to the surface of an inorganic multilayer substrate (dotted) from the first cycle of the series of potentials applied, with those calculated from molecular dynamics simulations for an untethered VSD:POPC membrane (solid) for the two pairs of potentials indicated, each membrane fully hydrated. Right side: the same comparison, but with the abscissa scale for the difference profiles calculated from the simulation expanded by 25%. The time-averaged profiles calculated from the simulations have been smoothed via convolution with a Gaussian whose 1/e width was 2σ.
