Abstract: An article comprises a structure having an outer surface extending along a longitudinal axis. At least a portion of a cross section of the outer surface is convex. Fluid control channels extend along a channel longitudinal axis along at least a portion the convex surface. The channel longitudinal axis makes an angle between 0 and 90 degrees with respect to the longitudinal axis of the outer surface. The fluid control channels are configured to allow capillary movement of liquid in the channels and across the convex surface.
