WebCapillary electrophoresis Hi everyone, I am currently completing a project where I am separating anions via CE. I am using a basic background electrolyte and a negative voltage (-30 kV). WebApr 12, 2024 · In both the inner and outer zones, the barbules lack the usual hooklets and grooves seen in contour feathers in other species of birds. On wetting, the helical coils of barbules in the inner zone unwind, rotating the barbules perpendicular to the plane of the vane, producing a dense forest of fibres that hold water through capillary action.
