Covering up : The greater ability of antifreeze proteins (AFPs), relative to polyvinyl pyrrolidone (PVP), to inhibit the reformation of gas hydrates, despite their smaller adsorption mass, has been explained by using a quartz crystal microbalance equipped with the ability to measure the dissipation factor ( D ). Whereas AFPs can form a rigid and compact film on the nucleating surface (A), PVP forms a porous and loose film (B).
