is expected for a system following the DLVO colloid theory.
At NaCl concentrations b153mMand experimental durations lower
than 1500 s, the A values showed very small changes (Fig. 4 and Video
S4). For [NaCl] ≥ 153 mM over the same time window, the A decreased
with time to values between 3 and 41% of its initial value. Moreover, at
the highest NaCl concentrations tested (537 and 997 mM) a linear decrease
of around 75–80% of the initial A was observed after 3–4 h
(Video S5).
