Fig. 2From: Wetting and adhesion properties of quasicrystals and complex metallic alloys 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 surfaceBack to article page
