(a1) A droplet first deposited onto a holder without a barrier (inset (a1)). (a2) Droplet with reduced curvatures as it spread across the substrate. (b1) Shows a droplet first deposited onto a holder with a fixed barrier (height of 1.04 mm) (Supplementary Video 4). (b2) Shows droplet holding its shape in the presence of the barrier showing the effect of liquid pinning. (Supplementary Video 5). The holder images are on a scale bar of 1 mm.
