Plot of cosθ versus x (see text) for 5 different liquids (see Table 1) and single crystalline alumina (top curve), single grained icosahedral APM (middle curve) and PTFE (bottom curve). Unlike its covering Al₂O₃ oxide (and major component Al, not shown here), the quasicrystal behaves like the apolar PTFE, showing clear evidence that no AB interactions take place at its surface
