The liquid surface energy parameters, the surface tension measured, work of adhesion and interfacial tension calculated for all the solvents, polymers and blends are summarized in Table 2.
The work of adhesion of Ge(110)/4H-SiC(0001) interface is higher than that of the Ge(111)/4H-SiC(0001) interface, leading to that Ge(110)/4H-SiC(0001) interface is more stable than Ge(111)/4H-SiC(0001) interface.
In order to determine the work of adhesion (a quantitative measure) between aggregates and bitumen, we measured the surface tension of bitumen in the presence of the PFM.

Work of adhesion (WOA) (mJ/[cm.sup.2]) and peak detachment force (PDF) (N/[cm.sup.2]) were calculated from force-distance plot using Texture Exponent 32 version 1.0.0.6.8 beta software package of the instrument.
Among specific topics are which fractal parameter contributes most to adhesion, the lattice gas Monte Carlo simulation of capillary forces in atomic force microscopy, new challenges at the nanoscale of the pull-off force and the work of adhesion, molecular mobility and interfacial dynamics in organic nano-electromechanical systems, and the plasma modification of polymer surfaces and their utility in building biomedical microdevices.
With regard to the determined work of adhesion and its limit ([W.sub.SL] for distilled water = 72.52 mJ; [W.sub.SL] for sea water = 73.53 mJ) the lowest energy or work required to separate the liquid from samples is associated with woven sample, which once again prove its extreme hydrophobicity.
In adhesion, the strain energy release rate is replaced by the interfacial work of adhesion, [W.sub.ad].
The aim of this study was to investigate the effect of surface free energy and the corresponding work of adhesion of biomaterial surfaces on such interactions.
where [W.sub.A] is the work of adhesion, [[Gamma].sub.1] is the surface energy of material i, and [[Gamma].sub.12] is the interfacial energy between materials 1 and 2.
According to Deryagin and Krotova, the high peel energies were due to dissipation of electrical charges and by comparing the system to a capacitor, the work of adhesion corresponded to the energy necessary to separate the two charged plates as predicted by the Paschen gas discharge curve.
The work of adhesion [W.sub.12], represents the energy needed for the separation of two surfaces in contact and is expressed by Dupre Eq.
