## Measurement of the contact angle of water, glycerol, formamide. methylene iodide, cc-bromonaphthalene, ethylene glycol and its aqueous solutions was carried out on the surface of Polish coal of rank 3 1.1,3 1.2,32.1, 32.2,33,34 and 35. On the basis of these results, the critical surface tension

The Helmholtz free energy of formation of a spherical microcluster in a ftite system is computed using different reelations for the curvature dependence of the surface tenson. Comparison between computer simulation results of Rao et aL and macroscopic thermodynanucs shows relalve close agreement.
We have investigated the impact of single droplets of various surfactant solutions on a low-surface-energy solid substrate using a high-frequency visualization technique (one picture every 100 ΞΌs). Whatever the surfactant, the drop spreads and retracts in about 1 s under the action of inertia and ca
